The 24RGLXM system pairs two units: the \u003cstrong\u003eAMUG24LMAS\u003c\/strong\u003e, a multi-position air handler that takes your old furnace’s place on the ductwork, and the \u003cstrong\u003eAOU24RGLX\u003c\/strong\u003e outdoor unit, running on R-410A. It is exactly the machine sold under the Fujitsu AIRSTAGE name, with the same model numbers. Since January 1, 2026, its manufacturer has gone by the corporate name GENERAL Inc. instead of Fujitsu General Limited; the spec sheet and the warranty have not changed by a single line.\u003c\/p\u003e\n\u003cp\u003eThe situation is a classic. The electric furnace in the basement is reaching the end of its life, the ducts are sound, and since the unit has to be replaced anyway, you want two things the old one could never do: cool the house in July and heat with something other than resistance for a good part of the winter. The 24RGLXM covers both by connecting to the air distribution you already have.\u003c\/p\u003e\n\u003cp\u003eCandour first, because it changes the math: the 24RGLXM carries \u003cstrong\u003eneither ENERGY STAR certification\u003c\/strong\u003e nor cold climate recognition, and Hydro-Québec has \u003cstrong\u003enot listed it for LogisVert\u003c\/strong\u003e. Its outdoor unit heats down to −21 °C; on colder nights, the electric backup carries the house.\u003c\/p\u003e\n\u003ch3\u003eGENERAL or Fujitsu AIRSTAGE: the same machine\u003c\/h3\u003e\n\u003cp\u003eThe name comes with a new owner: since August 2025, Paloma Rheem Holdings (Rheem’s parent group since 1988) has held the former Fujitsu General Limited; the corporate name GENERAL Inc. followed at the turn of 2026. Otherwise, nothing has moved. Kawasaki is still home to the head office and R\u0026amp;D, the same factories build the same AIRSTAGE units, and those keep their numbers as well as their warranty coverage. Rheem Canada has run the Canadian sales side since February 2026; we still buy from Groupe Master.\u003c\/p\u003e\n\u003cp\u003eWhile the transition lasts, the same unit circulates under two labels. So that two quotes can be compared without ambiguity, we publish both pages and the table below, value by value. This system also appears in our catalogue as a “central heat pump.”\u003c\/p\u003e\n\u003ctable class=\"tp-compare\"

An electric furnace turns each kilowatt-hour into the same amount of heat, no more, no less. A heat pump instead moves heat captured from the outdoor air into the house, which lets it deliver more energy than it consumes. The manufacturer rates the system at 27,000 BTU\/h in heating and 24,000 BTU\/h in cooling, at nominal conditions. When the house asks for more than the heat pump supplies, the backup kit joins in to make up the difference; below −21 °C, it heats alone.\u003c\/p\u003e\n\u003cp\u003eOn efficiency, AHRI certificate 205123807 gives the system an HSPF2 of 9.2, a SEER2 of 17.6 and an EER2 of 11.7. Two cold-weather readings appear as well, each taken at its own test point: 18,700 BTU of heating at −8 °C, then 19,800 BTU at −15 °C, where the \u003cstrong\u003eCOP\u003c\/strong\u003e is 1.80. That COP means that at −15 °C, every kilowatt-hour consumed still returns 1.80 in heat, where the old furnace’s elements returned just one.\u003c\/p\u003e\n\u003cp\u003eLet us put it in black and white: the 24RGLXM is not one of the manufacturer’s extra-low-temperature models, and during cold snaps the electric backup will take up more of your winter. If you are counting on Hydro-Québec’s help, or if the heat pump needs to hold on as far into the season as possible, we will price a LogisVert-listed system alongside it.\u003c\/p\u003e\n\u003cp\u003eIn summer, on the other hand, the AMUG24LMAS cools the whole house through the grilles that used to blow the furnace’s heat. Its all-aluminum coil also pulls humidity out of the air, and the water runs off through a drain.\u003c\/p\u003e\n\u003cp\u003eDuctwork designed for an electric furnace was not always sized for air conditioning, which often needs more air. The air handler offers a maximum airflow of 800 CFM and handles \u003cstrong\u003estatic pressure\u003c\/strong\u003e of up to 1.0 in. WC, a high value; its fan motor has adaptive control. That margin does not replace an adequate return: during the visit we check the return, the ducts and the grilles, and you know before installation whether a correction is needed.\u003c\/p\u003e\n\u003cp\u003eThe air handler adapts to the old furnace’s position, not the other way around. It is truly \u003cstrong\u003emulti-position\u003c\/strong\u003e: upflow in the basement, downflow in an upstairs closet, horizontal in a crawl space. The manufacturer includes the downflow and horizontal right kits with each unit at no charge. At 42.5 in. high, 21 in. wide and 21.69 in. deep, it needs minimum clearance on three sides and 21 in. clear in front for service.\u003c\/p\u003e\n\u003cp\u003eOn site, AirGreen, an \u003cstrong\u003eAIRSTAGE Elite Plus\u003c\/strong\u003e installer, removes the furnace, sets the air handler on the plenum, installs the backup kit, runs the refrigerant line, the cable and the drain, connects the 208\/230 V supply and provides an access panel for the filter. A \u003cstrong\u003erefrigeration technician\u003c\/strong\u003e then commissions the complete system.\u003c\/p\u003e\n\u003cp\u003eOutside, the outdoor unit, rated at 55.0 dB(A), measures 35.44 × 13 × 32.69 in.; we set it on a pad or a bracket, away from snow sliding off the roof and from bedroom windows.

The \u003cstrong\u003eAMUG30LMAS\u003c\/strong\u003e multi-position air handler goes on your ductwork in the furnace’s place; outside, the \u003cstrong\u003eAOUH30LUAH1\u003c\/strong\u003e unit gathers the heat. Fujitsu AIRSTAGE sells this combination under the same numbers. The manufacturer is the same: it simply adopted the name GENERAL Inc. on January 1, 2026, and neither its spec sheet nor its warranty has changed one bit.\u003c\/p\u003e\n\u003cp\u003eOn the cold side, it is one of the manufacturer’s extra-low-temperature systems.

The electric backup heat kit comes from the manufacturer and is installed on site, inside the unit, and the downflow and horizontal right kits come with every air handler at no additional cost. When the house dictates where the old furnace sits, those details make the difference.\u003c\/p\u003e\n\u003ch3\u003eGENERAL or Fujitsu AIRSTAGE: the same machine\u003c\/h3\u003e\n\u003cp\u003eThe group that has owned Rheem since 1988, Paloma Rheem Holdings, completed the purchase of Fujitsu General Limited in August 2025. The company then took as its corporate name a name it had already been using on its products since 1946: GENERAL Inc. It has not moved from Kawasaki, Japan, either for its head office or for its research and development; its factories, its AIRSTAGE model numbers and its warranty program have not been touched.\u003c\/p\u003e\n\u003cp\u003eCanadian sales have been entrusted to Rheem Canada since February 2026, and Groupe Master remains the supplier we order from.

Its cabinet measures 21 × 21.69 × 42.5 in., its coil is all aluminum, and the manufacturer calls for a minimum of clearance on three sides plus 21 in. in front of the cabinet for service.\u003c\/p\u003e\n\u003cp\u003eWinter is then shared between two sources. As long as the heat pump keeps up with the house’s demand, it heats alone: it does the main work. When the cold deepens and the house loses more heat than the outdoor unit supplies, the kit joins in to close the gap, without replacing the heat pump. The system heats down to −26 °C; below that, the electric backup takes the whole load.\u003c\/p\u003e\n\u003cp\u003eFor an electric furnace owner, the most telling figure is still the COP. Heating elements return one unit of heat per unit of electricity. AHRI certificate 207657376 gives the 30LUAH1M a \u003cstrong\u003eCOP of 3.03\u003c\/strong\u003e at the −8 °C test point, where the published capacity is 21,600 BTU, and still 1.76 at the −15 °C point, with 33,000 BTU. Each of these points has its own test conditions, and we report them as published. The heating season is summed up by an HSPF2 of 9.7; in cooling, SEER2 reaches 18.8 and EER2 stands at 11.7. The manufacturer’s nominal capacities: 32,000 BTU\/h of heat, 28,600 BTU\/h of cooling.\u003c\/p\u003e\n\u003cp\u003eThe $2,592 amount is the one the list gives, but Hydro-Québec has the final say on eligibility. For your file, note two references: AHRI certificate 207657376 and ENERGY STAR ID 2409932.\u003c\/p\u003e\n\u003cp\u003eYour ducts keep their role. The AMUG30LMAS moves up to 870 CFM and tolerates high \u003cstrong\u003estatic pressure\u003c\/strong\u003e, which can reach 1.0 in. WC; its fan motor follows an adaptive control. Before confirming the size, we check the ductwork and the \u003cstrong\u003ereturn air\u003c\/strong\u003e, since air conditioning, which the old furnace never offered, needs the air to reach the upstairs rooms properly. On sound, the indoor unit sits between 25 and 39 dB(A), and the outdoor unit is rated at 53.0 dB(A).\u003c\/p\u003e\n\u003cp\u003eAn outdoor unit expected to heat in deep cold needs air around it. The AOUH30LUAH1 measures 38.19 × 14.56 × 39.31 in.; we raise it on a pad or a bracket away from the eavestrough, and keep its sides free of any hedge or fence.\u003c\/p\u003e\n\u003cp\u003eThe replacement follows this order:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003evisit: condition of the furnace, the \u003cstrong\u003eplenum\u003c\/strong\u003e, the return air and the grilles, choice of the outdoor location;\u003c\/li\u003e\n\u003cli\u003eremoval of the electric furnace and installation of the AMUG30LMAS in the required position, with the mounting kit it needs;\u003c\/li\u003e\n\u003cli\u003einstallation of the electric backup heat kit in the unit;\u003c\/li\u003e\n\u003cli\u003ecable, drain and the two tubes of the refrigerant line, 3\/8 and 5\/8 in., outdoor pad or bracket, 208\/230 V supply and filter access panel;\u003c\/li\u003e\n\u003cli\u003ecommissioning: a \u003cstrong\u003erefrigeration technician\u003c\/strong\u003e checks how the heat pump operates as well as the backup.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003eThe outdoor unit and the air handler form a fully communicating heat pump.

It is the resistance the ductwork puts up against the air: every length of duct, every elbow, every grille and the filter itself add to it. In a split-level house, the branches are long and change levels, and the resistance climbs. A fan that runs short of pressure then delivers plenty of air to the rooms near the unit and very little to the bedroom at the far end.\u003c\/p\u003e\n\u003cp\u003eOn that front, the AMUG36LMAS holds its own: the manufacturer gives it high static pressure, with a ceiling of 1.0 in. WC; as for its \u003cstrong\u003efan motor\u003c\/strong\u003e, it is driven by an adaptive control. Maximum airflow reaches 1,200 CFM. If the upstairs bedroom has always been the coldest room in winter, the balance of the ductwork often has something to do with it.\u003c\/p\u003e\n\u003cp\u003eThat margin has its limits. An undersized return, a duct crushed under a floor or registers closed for years will hold back any unit. During the visit, we follow the ductwork level by level: supply, \u003cstrong\u003ereturn air\u003c\/strong\u003e, grilles, condition of the accessible ducts. If a return needs to be added or a branch corrected, the quote says so.\u003c\/p\u003e\n\u003cp\u003eIn this type of house, the furnace often sits in a utility room on the lowest level, sometimes in a closet. The AMUG36LMAS measures 21 in. wide, 21.69 in. deep and 57 in. high. Truly multi-position, it stands upright in upflow, works in downflow when it has to blow downward, or lies flat in a crawl space; the downflow and horizontal right kits are provided at no additional cost with each unit. You also need to keep 21 in. in front of the cabinet for service, on top of minimum clearance on three sides.\u003c\/p\u003e\n\u003cp\u003eAHRI certificate 207657377 gives the system an \u003cstrong\u003eHSPF2 of 10.4\u003c\/strong\u003e, a SEER2 of 17.1 and an EER2 of 11.0. At nominal conditions, the manufacturer rates it at 38,000 BTU\/h in heating and 33,000 BTU\/h in cooling. The certified file adds two cold-weather readings, each to be read on its own: 25,600 BTU of heating at −8 °C, and 42,000 BTU at −15 °C for a COP of 1.84. Heating continues down to −26 °C.\u003c\/p\u003e\n\u003cp\u003eThe heat pump supplies the heat as long as it meets the demand. When the house calls for more, the \u003cstrong\u003eelectric backup heat kit\u003c\/strong\u003e, supplied by the manufacturer and fitted on site inside the unit, joins in to make up the difference; below −26 °C, it handles the heating alone. Electric heat does not disappear from the house, then: it moves from the lead role to a supporting one.\u003c\/p\u003e\n\u003cp\u003eThe financial side is quickly summed up: no ENERGY STAR certification, no cold climate recognition, and Hydro-Québec did not include it in its LogisVert list of October 27, 2026. Extra-low-temperature heating describes the design of the outdoor unit according to the manufacturer; it does not qualify for any grant. If the grant is decisive for you, we will put a listed system alongside it for comparison.\u003c\/p\u003e\n\u003cp\u003eIn a split-level house, the unit is often half a floor away from the living room, and its sound matters: 25 dB(A) at its lowest, 40 dB(A) at full speed. The outdoor unit, for its part, is rated at 53.0 dB(A); its dimensions are 38.19 × 14.56 × 52.5 in. We find a spot with you on a pad or a bracket, out of reach of the snow from the roof and away from bedroom windows.\u003c\/p\u003e\n\u003cp\u003eThe job, as we run it:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003esurvey of the ductwork on every level and check of the plenum;\u003c\/li\u003e\n\u003cli\u003eremoval of the electric furnace and installation of the AMUG36LMAS in the chosen position, with the backup kit;\u003c\/li\u003e\n\u003cli\u003erefrigerant line (3\/8 and 5\/8 in.), cable, drain and 208\/230 V supply;\u003c\/li\u003e\n\u003cli\u003efilter access panel, placed where you can reach it without contortions;\u003c\/li\u003e\n\u003cli\u003ecommissioning by a \u003cstrong\u003erefrigeration technician\u003c\/strong\u003e, who also checks that air reaches the farthest rooms.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eControls are straightforward: the heat pump is fully communicating, Wi-Fi can be added as an option, and an external input\/output interface, also optional, is used to interlock the system with third-party systems.

Check it often, keep the drain clear and free the outdoor unit after snowfalls. On coverage, the compressor and parts each get 12 years, and labour 6.

The AMUG48LMAS stands 57 in. high; on the floor, it takes up 21 in. by 21.69 in. The manufacturer requires clearance on three sides, at a minimum, and \u003cstrong\u003e21 in. in front\u003c\/strong\u003e for service. In a narrow room, that front space is what gets negotiated: neither the door, nor the water heater, nor the neighbouring electrical panel should encroach on it.\u003c\/p\u003e\n\u003cp\u003eBefore quoting, we measure the room as it really is: width between the walls, height under the joists, door swing, position of the floor drain, the water heater and the electrical panel. If the front of the unit cannot stay clear, the quote says so, along with the solution we propose.\u003c\/p\u003e\n\u003cp\u003eWhen the room truly leaves no space, the \u003cstrong\u003emulti-position\u003c\/strong\u003e design opens other options. The unit can lie horizontally in a crawl space or blow in downflow from a closet; the downflow kit and the horizontal right kit are part of the delivery, at no cost. We choose the position with you, based on the duct layout.\u003c\/p\u003e\n\u003cp\u003eThe extension also raises the question of the ductwork. If the added rooms are connected to extensions of the original ducts, the air has to travel a long way to reach them. The AMUG48LMAS offers a maximum airflow of \u003cstrong\u003e1,640 CFM\u003c\/strong\u003e, high allowable \u003cstrong\u003estatic pressure\u003c\/strong\u003e (1.0 in. WC at most) and adaptive control for the fan motor. If the extension never had grilles and heats with baseboards, we look with you at whether extending the ductwork there is worth it; the branches and grilles to add are decided during the visit.\u003c\/p\u003e\n\u003cp\u003eIn heating, the manufacturer rates the system at 51,000 BTU\/h at nominal conditions, against 45,500 BTU\/h in cooling. AHRI certificate 207657378, for its part, publishes 34,400 BTU at −8 °C, then 51,000 BTU with a COP of 1.92 at −15 °C; these are two test points, each with its own conditions, and we do not set them against each other. The HSPF2 is 10.0, the SEER2 16.6 and the EER2 8.8. Heating continues down to −26 °C.\u003c\/p\u003e\n\u003cp\u003eOn days when the heat pump is no longer enough for a house this size, the \u003cstrong\u003eelectric backup heat kit\u003c\/strong\u003e, original manufacturer equipment installed on site inside the unit’s cabinet, adds its heat to the heat pump’s; below −26 °C, it heats alone. At commissioning, the refrigeration technician checks that the two sources hand off to each other properly.\u003c\/p\u003e\n\u003cp\u003eOn the program side, there is nothing to claim: the 48LMAH1M does not carry ENERGY STAR certification, is not recognized as cold climate and is absent from the LogisVert list as of October 27, 2026. We are putting it in writing now so that your comparison of quotes happens on equal terms.\u003c\/p\u003e\n\u003cp\u003eAn extended bungalow often collects other equipment over the course of renovations. The external input\/output interface, available as an option, allows the system to be interlocked with third-party systems. The heat pump, for its part, is fully communicating with the air handler, and Wi-Fi is optional.\u003c\/p\u003e\n\u003cp\u003eIf the mechanical room adjoins a bedroom or an office, the door and the insulation matter: the indoor unit runs between 29 and 47 dB(A) depending on speed. Outside, the AOUH48LMAH1 (38.19 × 14.56 × 52.5 in.) is rated at 54.0 dB(A); a pad or a bracket places it on the side of the lot where it bothers people least, out of reach of the snow sliding off the roof.\u003c\/p\u003e\n\u003cp\u003eIn practical terms, the job includes:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ea survey of the mechanical room and the ductwork, including the extension’s branches;\u003c\/li\u003e\n\u003cli\u003eremoval of the electric furnace and installation of the AMUG48LMAS on the plenum, existing or new;\u003c\/li\u003e\n\u003cli\u003einstallation of the backup kit and of a filter access panel that stays clear;\u003c\/li\u003e\n\u003cli\u003ethe cable, the drain, the 208\/230 V supply and the refrigerant line (3\/8 and 5\/8 in. diameters);\u003c\/li\u003e\n\u003cli\u003ecommissioning by a \u003cstrong\u003erefrigeration technician\u003c\/strong\u003e.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eIn a narrow room, maintenance is settled at the design stage. A filter that cannot come out without moving the water heater ends up forgotten; so we put the access panel on the clear side and leave the drain visible. The compressor is warranted for 12 years, the parts too, labour for 6 years; for exact dimensions, the manufacturer’s technical document, in French and English versions, comes with the listing.\u003c\/p\u003e\n\u003cp\u003eThe 48LMAH1M suits:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ethe large extended bungalow whose electric furnace feeds the whole duct system, old and new;\u003c\/li\u003e\n\u003cli\u003ethe owner who wants a 4-ton size heating down to −26 °C and accepts doing without a grant;\u003c\/li\u003e\n\u003cli\u003eless so the mechanical room where the front of the unit cannot stay clear and no other position is possible.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eBordeaux-Cartierville: have your mechanical room measured before replacing the furnace\u003c\/h3\u003e\n\u003cp\u003eIn Bordeaux-Cartierville, our visit starts where space is tightest: the mechanical room, tape measure in hand.

We measure the space freed up by the furnace and the height up to the plenum; if a transition piece is needed between the unit and the existing plenum, it is in the quote. In a basement, the air handler is normally installed in upflow, like the furnace it replaces, but it can also blow downward, with the UTD-DFMSB1 kit, or lie on its left or right side when the ceiling is low.\u003c\/p\u003e\n\u003cp\u003eOn a cold January night, the roles split like this. The outdoor unit adjusts the speed of its Inverter compressor and supplies the base heat; the air handler pushes it through the ducts. If the house asks for more than the heat pump delivers, the air handler turns on the backup kit according to the logic selected among those it offers, then shuts it off when demand drops. The furnace did everything with its elements; here, they only step in as reinforcement.\u003c\/p\u003e\n\u003cp\u003eAt −8 °C, the manufacturer’s sheet lists 10,600 BTU for a COP of 1.36; at −15 °C, 16,100 BTU for a COP of 2.06. These two measurements come from different test points: take each one for what it is, without setting one against the other. Rated heating capacity is 16,000 BTU at 8.3 °C (range of 3,400 to 17,800 BTU), and the manufacturer claims for the series a rated heating capacity up to 33% above nominal capacity. The outdoor unit heats down to −21 °C, and the brochure announces “no lockout” at low temperatures.\u003c\/p\u003e\n\u003cp\u003eOne ton remains a small capacity, made for a modest, well-insulated bungalow. In a bigger or colder house, the backup would run too often: we would then suggest a larger size from the same series. Capacity is set at the visit, not from the old furnace’s nameplate.\u003c\/p\u003e\n\u003cp\u003eIn summer, the unit that was heating blows cool air through the same grilles: 12,000 BTU nominal, modulated from 3,100 to 13,600 BTU, and dehumidification of 1.29 pints per hour, which you notice in a bungalow where all of daily life happens on one floor. AHRI certificate 217290592: 19.9 \u003cstrong\u003eSEER2\u003c\/strong\u003e, 10.3 \u003cstrong\u003eHSPF2\u003c\/strong\u003e and 13.0 EER2; ENERGY STAR certifies it in the cold climate category (ID 4428945).\u003c\/p\u003e\n\u003cp\u003eIn a bungalow basement, the air handler works right below the bedrooms. At idle, it holds at 30 dB(A); at full speed, it does not go above 42 dB(A). Outside, the compact AOUH12KUAS1 unit is rated at 49.0 dB(A): never, if it can be avoided, under a bedroom window, yours or the one next door.\u003c\/p\u003e\n\u003cp\u003eThe air handler moves up to 500 CFM and works with an external \u003cstrong\u003estatic pressure\u003c\/strong\u003e between 0.08 and 0.80 in. WC. With a heat pump, the blower runs for long stretches at low speed instead of blowing in big hot bursts, and a choked duct gives itself away at the farthest grilles. So we measure the duct system before reusing it; the number of grilles or an added return air are decided at that point.\u003c\/p\u003e\n\u003cp\u003eBetween the two units, the refrigerant line set, in 1\/4 and 3\/8 in., runs at least 16 ft (5 m) and at most 98 ft (30 m); the allowed height difference is 49 ft (15 m), and the unit ships precharged for 66 ft (20 m). The system connects at 208\/230 V (MCA of 15 A), after we check your electrical panel. A refrigeration technician handles commissioning and sets up the backup, and an access hatch stays in front of the filter and the service panels.\u003c\/p\u003e\n\u003cp\u003eThe control is chosen separately: a KAGAMI UTY-RVRU or UTY-RNRUZ5 wired controller on the wall, the AIRSTAGE Mobile app over Wi-Fi, a third-party 24 V thermostat connected through the UTY-TTRXZ1 interface, or the wireless remote of the IR receiver kit. Day to day, the filter is changed through the hatch (optional 16 × 20 in. filter base), the built-in leak detection keeps an eye on the R-32 circuit, and service monitoring runs through a compatible controller.\u003c\/p\u003e\n\u003cp\u003eHydro-Québec lists this system under LogisVert: a $1,272 grant according to the October 27, 2026 list. On the manufacturer’s side, coverage is 12 years on compressor and parts, and 6 on labour. For dimensional drawings and complete performance data, the manufacturer’s spec sheet comes with the product in its bilingual GENERAL version, prepared by AirGreen.\u003c\/p\u003e\n\u003cp\u003eIt is meant for the owner of a small bungalow already equipped with ducts who wants to replace the electric furnace without touching the air distribution, and gain air conditioning along the way.\u003c\/p\u003e\n\u003ch3\u003eOfficial brochures\u003c\/h3\u003e\n\u003cp\u003eThe manufacturer's brochures are available as PDF files:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0715\/1694\/6724\/files\/GENERAL_AIRSTAGE_CENTAURI_THERMOPOMPE_CENTRALE_AMUH12-48KUAS_BROCHURE_FR_anciennement_Fujitsu_AirGreen.pdf\" target=\"_blank\" rel=\"noopener\"\u003eBrochure in French (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0715\/1694\/6724\/files\/GENERAL_AIRSTAGE_CENTAURI_CENTRAL_HEAT_PUMP_AMUH12-48KUAS_BROCHURE_EN_formerly_Fujitsu_AirGreen.pdf\" target=\"_blank\" rel=\"noopener\"\u003eBrochure in English (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSault-au-Récollet and all of Montreal: the visit first, the free quote after\u003c\/h3\u003e\n\u003cp\u003eIn Sault-au-Récollet, we go down to look at the furnace, the plenum connection and the return air, then we head outside to find where the outdoor unit should go.

The AMUH18KUAS cabinet measures 17.5 × 21 × 43 in. in width, depth and height, and you have to allow space in front of it to open the panels and slide out the filter. We measure the usable width and depth, the clear height, the door and the floor opening that leads to the supply plenum. If the frame was built tight around the old furnace, the necessary modification is in the quote instead of being discovered on installation day.\u003c\/p\u003e\n\u003cp\u003eThe replacement then goes in this order:\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003epower shut-off and removal of the electric furnace;\u003c\/li\u003e\n\u003cli\u003einspection of the floor opening and the plenum under the closet;\u003c\/li\u003e\n\u003cli\u003einstallation of the air handler in downflow on the UTD-DFMSB1 kit, with the return air connected at the top;\u003c\/li\u003e\n\u003cli\u003eaddition of the compatible manufacturer \u003cstrong\u003eelectric backup heat kit\u003c\/strong\u003e, sold separately, on its dedicated power supply;\u003c\/li\u003e\n\u003cli\u003erouting of the refrigerant line set (1\/4 and 1\/2 in.), the cable and the drain to the outside, then setting the outdoor unit on its pad or bracket;\u003c\/li\u003e\n\u003cli\u003econnection at 208\/230 V and commissioning by a refrigeration technician, who sets the backup logic.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003eThe drain deserves a closer look. An electric furnace produces no water; an air handler does. In summer, its coil removes 2.37 pints of water per hour from the air according to the manufacturer, and in a house without a basement, a floor drain is rarely close to the closet. We map out the drain route at the visit, with a condensate pump when there is not enough natural slope.\u003c\/p\u003e\n\u003cp\u003eLeak detection makes full sense in this closet: the air handler shares the air of the neighbouring rooms, and the monitoring of its R-32 circuit comes standard, with no accessory to add. For service monitoring, a compatible controller is all it takes.\u003c\/p\u003e\n\u003cp\u003eNext to the kitchen or the bedrooms, noise also weighs in the choice. The AMUH18KUAS stays at 33 dB(A) at its lowest speed and climbs to 44 dB(A) at its highest. Outside, the AOUH18KUAS1 unit is rated at 55.0 dB(A), which is why the wall it backs onto should be chosen with care.\u003c\/p\u003e\n\u003cp\u003eUnder-floor ducts in a house without a basement can be long and tight. The air handler delivers up to 600 CFM; on the external \u003cstrong\u003estatic pressure\u003c\/strong\u003e side, it handles 0.08 to 0.80 in. WC. The margin is there, but we do not reuse a duct system without measuring it. The number of grilles and the location of the return air are confirmed on site.\u003c\/p\u003e\n\u003cp\u003eIn heating, the heat pump carries most of the load: 21,600 BTU nominal at 8.3 °C, modulating from 3,100 to 24,000 BTU. The manufacturer also publishes 16,100 BTU with a COP of 2.91 at −8 °C, and 17,300 BTU with a COP of 2.4 at −15 °C; these values come from different test points and are each read on their own. The outdoor unit, compact and universal, compatible with all of the manufacturer’s non-wall single-zone systems, heats down to −21 °C, and the brochure speaks of “no lockout” at low temperatures. When the heat pump can no longer keep up with demand, the electric kit takes over according to the selected logic.\u003c\/p\u003e\n\u003cp\u003eIn cooling, the 18,000 BTU nominal modulates from 3,100 to 20,100 BTU. Under AHRI certificate 217290593, the system posts 19.2 SEER2, 10.5 HSPF2 and 12.2 EER2, and ENERGY STAR places it in the cold climate category (ID 4428946).\u003c\/p\u003e\n\u003cp\u003eWithout a basement, the refrigerant line set usually exits through the wall, close to the closet. The allowed length is between 16 and 98 ft (5 and 30 m), for a height difference of at most 49 ft (15 m) and a precharge covering 66 ft (20 m); the outdoor unit is placed to keep that run short and clean.\u003c\/p\u003e\n\u003cp\u003eThe old furnace’s thermostat is not necessarily suited to this system, and no control comes with the air handler. You choose between a KAGAMI wired controller (UTY-RVRU or UTY-RNRUZ5), the IR receiver kit and its wireless remote, Wi-Fi through the AIRSTAGE Mobile app, or a third-party 24 V thermostat connected through the UTY-TTRXZ1 interface.\u003c\/p\u003e\n\u003cp\u003eFor maintenance, the filter is reached through the closet door, and the manufacturer sells an optional filter base (16 × 20 in.). A tip from the field: a closet kept free of boxes and brooms is a filter that actually gets changed.\u003c\/p\u003e\n\u003cp\u003eOn the grant side, this system is listed in Hydro-Québec’s LogisVert program for $1,932 (list of October 27, 2026). The manufacturer’s warranty: compressor and parts, 12 years each; labour, 6 years.

The figure that decides is \u003cstrong\u003estatic pressure\u003c\/strong\u003e, in other words the resistance the duct system puts up against the blower. The AMUH24KUAS handles between 0.08 and 0.80 in. WC of external static pressure and moves up to 750 CFM: a wide range, which leaves room for ducts from another era.\u003c\/p\u003e\n\u003cp\u003eAt the visit, we take the pulse of the existing duct system:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003estatic pressure, read at the supply plenum and at the return air;\u003c\/li\u003e\n\u003cli\u003ethe size and condition of the main ducts and the branches;\u003c\/li\u003e\n\u003cli\u003ethe number and size of the return air openings, often the weak link in older duct systems;\u003c\/li\u003e\n\u003cli\u003egrilles that are closed, blocked or badly placed;\u003c\/li\u003e\n\u003cli\u003ethe tightness of the joints visible in the basement.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eIf a reading falls outside the air handler’s range, we propose a targeted correction, for example an added return air or an enlarged section, rather than a new duct system. That is when, readings in hand, the layout and the number of grilles are settled.\u003c\/p\u003e\n\u003cp\u003eThe second thing you can keep: the wall thermostat. The system accepts a third-party 24 V thermostat, connected through the optional UTY-TTRXZ1 interface. What remains to be seen is what your thermostat can do: a model meant for an electric furnace alone generally handles neither cooling nor the heat pump, and in that case we replace it with a suitable 24 V thermostat that the interface connects to the system. Otherwise, other controls are available, all optional since the system includes none: a KAGAMI UTY-RVRU or UTY-RNRUZ5 wired controller, Wi-Fi with the AIRSTAGE Mobile app, or the IR receiver kit, which comes with its wireless remote.\u003c\/p\u003e\n\u003cp\u003eWhat changes is the heat source. The outdoor unit captures heat outside with an Inverter compressor that modulates its speed, and its refrigerant, R-32, has a low global warming potential; the air handler distributes that heat through your ducts. For the coldest days, it takes the \u003cstrong\u003eelectric backup heat kit\u003c\/strong\u003e the manufacturer designed for it, sold separately and powered by a dedicated circuit, which it manages itself according to one of its built-in logics; the refrigeration technician sets that choice at commissioning.\u003c\/p\u003e\n\u003cp\u003eWhat the sheet says for winter: 27,000 BTU of rated heating at 8.3 °C, modulating from 5,400 to 32,000 BTU, then two test points published separately, namely 18,200 BTU with a COP of 2.93 at −8 °C and 24,600 BTU with a COP of 2.14 at −15 °C. Since these two measurements do not share the same conditions, we give them without relating one to the other. Heating works down to −21 °C, with no cold-weather lockout according to the brochure. According to the manufacturer, the series’ rated heating capacity climbs up to 33% above nominal capacity.\u003c\/p\u003e\n\u003cp\u003eIn a semi-detached house, the outdoor unit always has a neighbour. It is rated at 54.0 dB(A); fortunately, the refrigerant line set (1\/4 and 1\/2 in.) allows up to 164 ft (50 m) and no less than 16 ft (5 m), a height difference of 98 ft (30 m) and a precharge for 66 ft (20 m), which lets us move the unit away from the terrace next door.\u003c\/p\u003e\n\u003cp\u003eIndoors, 28 dB(A) at minimum speed, 42 dB(A) at the top. The cabinet (17.5 × 21 × 43 in.) sits in the basement in upflow where the furnace was, but it also accepts downflow with the UTD-DFMSB1 kit and the horizontal position, left or right.\u003c\/p\u003e\n\u003cp\u003eIn summer, the same machine cools through the same grilles: 24,000 BTU nominal, with modulation from 5,400 to 28,000 BTU, and 3.08 pints of water removed from the air every hour. AHRI certificate 217290594 records 17.7 SEER2, 10.1 HSPF2 and 11.8 EER2, and the system carries ENERGY STAR cold climate certification (ID 4428948).\u003c\/p\u003e\n\u003cp\u003eThe job follows a familiar sequence: furnace removal, air handler set on the plenum, return air connection, access hatch for maintenance and the filter, refrigerant line set, cable and drain to the outdoor unit set on a pad, connection at 208\/230 V, then commissioning by a refrigeration technician. Afterwards, maintenance goes through the hatch, where the filter is changed (with an optional 16 × 20 in. filter base); the built-in leak detection watches over the refrigerant, and an existing humidifier or HRV can be connected to the air handler’s input\/output terminals.\u003c\/p\u003e\n\u003cp\u003eThe grant carries weight in this project: Hydro-Québec’s LogisVert list of October 27, 2026 assigns $2,184 to this system. Since Hydro-Québec updates this list, the amount is rechecked on the day of the quote. Warranty from the manufacturer: 12 years for compressor and parts, 6 years for labour. For performance data and dimensional drawings, open the bilingual spec sheet that comes with the product, in the GENERAL version prepared by AirGreen.\u003c\/p\u003e\n\u003cp\u003eThis system suits the mid-sized semi-detached house whose duct system passes our checks and whose load matches 2 tons. If the calculation shows more, the CENTAURI series goes up in capacity without changing principle.\u003c\/p\u003e\n\u003ch3\u003eOfficial brochures\u003c\/h3\u003e\n\u003cp\u003eThe manufacturer's brochures are available as PDF files:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0715\/1694\/6724\/files\/GENERAL_AIRSTAGE_CENTAURI_THERMOPOMPE_CENTRALE_AMUH12-48KUAS_BROCHURE_FR_anciennement_Fujitsu_AirGreen.pdf\" target=\"_blank\" rel=\"noopener\"\u003eBrochure in French (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0715\/1694\/6724\/files\/GENERAL_AIRSTAGE_CENTAURI_CENTRAL_HEAT_PUMP_AMUH12-48KUAS_BROCHURE_EN_formerly_Fujitsu_AirGreen.pdf\" target=\"_blank\" rel=\"noopener\"\u003eBrochure in English (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eChampfleury and everywhere in Laval: your free quote, with the ducts measured\u003c\/h3\u003e\n\u003cp\u003eIn Champfleury, we measure the static pressure of your ducts, look at your thermostat and choose with you where to set the outdoor unit.

These two models carry exactly the same numbers as the Fujitsu AIRSTAGE twin: same machine, same manufacturer’s sheet, same warranty. The manufacturer only changed its banner on January 1, 2026: Fujitsu General Limited was renamed GENERAL Inc.\u003c\/p\u003e\n\u003cp\u003eGoing from two units to one means one machine for both seasons, a single control and a single set of equipment to maintain. It is also the right time to review a duct system that has served two masters for years.\u003c\/p\u003e\n\u003ch3\u003eGENERAL or Fujitsu AIRSTAGE: the same machine\u003c\/h3\u003e\n\u003cp\u003eThe new banner follows logically from a change of owner. In August 2025, Fujitsu General was acquired by Paloma Rheem Holdings, Rheem’s parent group since 1988; on the first day of 2026, the company took the name GENERAL Inc. The GENERAL name itself has served as a brand since 1946. On the product side, nothing to report: the factories, the head office and R\u0026amp;D in Kawasaki, Japan, the AIRSTAGE model numbering and the warranty program all stay in place.\u003c\/p\u003e\n\u003cp\u003eThe Fujitsu brand is fading out in stages, so we sell the same machine under two names. Since February 2026, sales in Canada have been Rheem Canada’s business; our units still come through Groupe Master. Both product pages remain online: the line-by-line comparison in the table speaks for itself.\u003c\/p\u003e\n\u003ctable class=\"tp-compare\"

It replaces the furnace-and-coil stack with a single cabinet; we measure the height available up to the plenum to plan the connection. In a basement, it is usually installed in upflow. Downflow requires the UTD-DFMMB1 kit, and the horizontal left and right positions are also allowed.\u003c\/p\u003e\n\u003cp\u003eThe air conditioner’s old refrigerant line set is not reused by default. Its route and its wall penetrations can sometimes serve again; the copper itself we assess on site, based on the required diameters and its condition. Same thing for the condenser’s location: if it suits the outdoor unit, which measures 31 × 12.63 × 37 in., we keep it, otherwise we propose another one. Line length can reach 164 ft (50 m) without going below 16 ft (5 m), a height difference of up to 98 ft (30 m) is allowed, and the precharge is good for 66 ft (20 m).\u003c\/p\u003e\n\u003cp\u003eIn winter, heat no longer comes from the elements but from the outside air. Rated heating capacity is 32,000 BTU at 8.3 °C and varies between 9,200 and 38,000 BTU. The sheet also lists 22,200 BTU for a COP of 2.96 at −8 °C, then 29,400 BTU for a COP of 2.18 at −15 °C: two test points with distinct conditions, to be read separately. The unit keeps heating down to −21 °C, and the manufacturer’s brochure states “no lockout” at low temperatures. The manufacturer also claims, for the series, up to 33% of rated heating capacity over and above nominal capacity.\u003c\/p\u003e\n\u003cp\u003eThe old furnace’s elements have a successor: the backup kit housed in the air handler. The air handler brings it in according to the logic chosen among those it offers, when the heat pump no longer meets demand, and the refrigeration technician sets it at commissioning.\u003c\/p\u003e\n\u003cp\u003eIn summer, the same Inverter compressor handles cooling: 30,000 BTU nominal, modulated between 9,600 and 35,000 BTU. It slows down on mild days instead of constantly starting and stopping like a single-speed air conditioner, and the air handler removes 3.47 pints of water per hour from the house air. AHRI certificate 217290595 credits it with a SEER2 of 19.0, an HSPF2 of 10.0 and an EER2 of 11.7; ENERGY STAR classifies it in the cold climate category (ID 4428947).\u003c\/p\u003e\n\u003cp\u003eA duct system that first served a furnace, then had a coil added, can hide restrictions. The new air handler moves up to 1,000 CFM and accepts 0.2 to 0.8 in. WC of external \u003cstrong\u003estatic pressure\u003c\/strong\u003e. We take that reading on the existing duct system, return air included, before confirming the layout and the number of grilles.\u003c\/p\u003e\n\u003cp\u003eIn the basement, the air handler stays discreet: 32 dB(A) at its lowest, 43 dB(A) at its highest. Outside, count on 55.0 dB(A) for the outdoor unit. On the electrical side, power is 208\/230 V, with an MCA of 24 A; we review the circuits of the old furnace and the old air conditioner, as well as the one the backup kit requires.\u003c\/p\u003e\n\u003cp\u003eOne control, then, and you choose it, since none comes with the system. Wi-Fi runs through the AIRSTAGE Mobile app; on the wall, we install a KAGAMI wired controller (UTY-RVRU or UTY-RNRUZ5) or a third-party 24 V thermostat wired via the UTY-TTRXZ1 interface; the IR receiver kit, for its part, provides a wireless remote. The BACnet and Modbus protocols are mostly useful in a managed building. The input\/output terminals accept a humidifier or an HRV\/ERV if needed.\u003c\/p\u003e\n\u003cp\u003eMaintenance now focuses on a single unit, starting with its filter, reached through an access hatch (optional 20 × 20 in. filter base). The built-in leak detection monitors the refrigerant; as for service monitoring, it is done through a compatible controller.\u003c\/p\u003e\n\u003cp\u003eLogisVert, the Hydro-Québec program, lists this system at $2,664 on its October 27, 2026 list. The manufacturer’s warranty protects the compressor and parts for 12 years; labour is protected for 6 years. The manufacturer’s spec sheet, in the bilingual GENERAL version AirGreen prepared, is supplied with the product, with its performance data and dimensional drawings. AirGreen also offers this system under the name “central heat pump”.\u003c\/p\u003e\n\u003cp\u003eIt is meant for a house heated by an electric furnace and cooled by a separate central unit, with a 2.5-ton load, when the owner prefers a single system to two successive replacements.\u003c\/p\u003e\n\u003ch3\u003eOfficial brochures\u003c\/h3\u003e\n\u003cp\u003eThe manufacturer's brochures are available as PDF files:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0715\/1694\/6724\/files\/GENERAL_AIRSTAGE_CENTAURI_THERMOPOMPE_CENTRALE_AMUH12-48KUAS_BROCHURE_FR_anciennement_Fujitsu_AirGreen.pdf\" target=\"_blank\" rel=\"noopener\"\u003eBrochure in French (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0715\/1694\/6724\/files\/GENERAL_AIRSTAGE_CENTAURI_CENTRAL_HEAT_PUMP_AMUH12-48KUAS_BROCHURE_EN_formerly_Fujitsu_AirGreen.pdf\" target=\"_blank\" rel=\"noopener\"\u003eBrochure in English (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eLavaltrie and the North Shore: have both of your units assessed, get a single free quote\u003c\/h3\u003e\n\u003cp\u003eIn Lavaltrie, we examine the furnace, the coil and the condenser, measure the static pressure of the duct system and check the electrical panel.

The old ones leave with the old furnace, but their job stays: the \u003cstrong\u003eelectric backup heat kit\u003c\/strong\u003e, housed in the air handler, takes it over.

The old furnace comes out. In its place, the AMUH36KUAS (21 × 21 × 48 in., W × D × H) takes over the existing supply \u003cstrong\u003eplenum\u003c\/strong\u003e and \u003cstrong\u003ereturn air\u003c\/strong\u003e, once the ducts have been checked during the visit. The room \u003cstrong\u003egrilles\u003c\/strong\u003e stay where they are. What gets added: outside, the outdoor unit, mounted on a pad or a bracket, and, to connect the two units, a 3\/8 and 5\/8 in. refrigerant line that runs together with the cable and the drain. An electric furnace never had to get rid of water; the air handler, on the other hand, collects condensate in summer and needs a way out for it. If needed, it can also be mounted downflow (UTD-DFMMB1 kit) or horizontally, left or right.\u003c\/p\u003e\n\n\u003cp\u003eIn winter, the system follows a well-defined sequence:\u003c\/p\u003e\n\n\u003col\u003e\n\u003cli\u003e\u003cstrong\u003eMild weather\u003c\/strong\u003e: the heat pump heats on its own. The Inverter compressor slows down or speeds up with demand; at 8.3 °C, the brochure gives it 38,000 BTU of rated heating, modulating from 9,200 to 43,000 BTU.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eReal cold\u003c\/strong\u003e: the heat pump keeps carrying the house. The certified tests give two separate reference points, each to be taken for what it is: 27,400 BTU with a COP of 2.85 at −8 °C, and 32,000 BTU with a COP of 2.18 at −15 °C.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eDemand above what the heat pump delivers\u003c\/strong\u003e: the backup kit comes into play, according to the backup logic selected at commissioning.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eColder than −21 °C\u003c\/strong\u003e: you are outside the outdoor unit's operating range, which the brochure describes as running with no low-temperature lockout down to that limit. The electric backup then takes over.\u003c\/li\u003e\n\u003c\/ol\u003e\n\n\u003cp\u003eChoosing that logic matters more than any other setting. Among the \u003cstrong\u003ebackup heat\u003c\/strong\u003e logics the air handler offers, we look for the one that strikes the right balance: the heat pump doing most of the season, and the backup arriving early enough that the house does not lose ground during a cold snap. The kit is a manufacturer accessory, sold separately, that needs its own power supply; before proposing one, we look at the electrical panel and at the old furnace's circuit.\u003c\/p\u003e\n\n\u003cp\u003eThat leaves everything orbiting the furnace, starting with the air exchanger and the humidifier that are often grafted onto it. The built-in \u003cstrong\u003einput\/output terminals\u003c\/strong\u003e of the AMUH36KUAS link them to the air handler, instead of letting each one run on its own schedule. The exchanger (HRV or ERV) and the humidifier connect there, and so can, if needed, a third-party auxiliary heater, a fire alarm or a door switch. During the visit, we note how each one is tied into the furnace today, so we can recreate the same links on the new unit.\u003c\/p\u003e\n\n\u003cp\u003eOn AHRI certificate 217290596, you read a SEER2 of 17.6, an HSPF2 of 9.8 and an EER2 of 10.6. The system is \u003cstrong\u003eENERGY STAR cold climate\u003c\/strong\u003e certified under ID 4428949. And it cools, which your electric furnace never did: the brochure lists 36,000 BTU of rated cooling across a 9,600 to 39,000 BTU range, and the spec sheet puts dehumidification at 3.82 pints\/h.\u003c\/p\u003e\n\n\u003cp\u003eWith its 1,207 CFM maximum airflow and an allowed external \u003cstrong\u003estatic pressure\u003c\/strong\u003e of 0.2 to 0.8 in. WC, the air handler tells you what your ducts will have to carry; their routing and the number of grilles are decided on site. The air handler runs at 31 dB(A) at its lowest speed and 46 dB(A) at maximum. As for the AOUH36KUAS1, it shows 56 dB(A) and its cabinet measures 31 × 12.63 × 37 in.\u003c\/p\u003e\n\n\u003cp\u003eThe refrigerant line limits leave room to work: 50 m (164 ft) at most, 20 m (66 ft) of it covered by the precharge, 5 m (16 ft) at least and 30 m (98 ft) of maximum height difference. The heat pump connects to a circuit of its own, at 208\/230 V (MCA 25 A, MOP 25 A), and the kit to its own. The filter stays reachable through an access panel, and starting up the system, the commissioning, is a refrigeration technician's job. AirGreen, an HVAC contractor holding an RBQ licence, is an AIRSTAGE Elite Plus installer.\u003c\/p\u003e\n\n\u003cp\u003eNo control comes with the unit. If your 24 V wall thermostat can run a heat pump and its backup, the UTY-TTRXZ1 interface lets you keep it. Otherwise, three routes: a KAGAMI UTY-RVRU or UTY-RNRUZ5 wired wall controller, \u003cstrong\u003eWi-Fi\u003c\/strong\u003e through the AIRSTAGE Mobile app, or a wireless remote with its IR receiver kit; compatible controllers add service monitoring.\u003c\/p\u003e\n\n\u003cp\u003eAmong the options is a filter base (20 × 20 in.); leak detection, for its part, comes built into the unit. One difference from the old furnace: this system also works in summer, so the filter gets dirty over two seasons instead of one.\u003c\/p\u003e\n\n\u003cp\u003eAs of October 27, 2026, Hydro-Québec listed this system in its \u003cstrong\u003eLogisVert\u003c\/strong\u003e program for a $3,288 grant; the list in force when you apply is the one that counts. The manufacturer's warranty runs 12 years on the compressor and parts; labour, 6 years. We also offer this same system under the \"central heat pump\" name.\u003c\/p\u003e\n\n\u003cp\u003eThis size is aimed at the family home heated by an electric furnace with ducts in good shape, especially when an air exchanger or a humidifier is already connected. A house heated by baseboards, with no ducts at all, is not the right starting point. As for the 3 tons, they are confirmed by a calculation made on site, never by a remote estimate.\u003c\/p\u003e\n\n\u003ch3\u003eOfficial brochures\u003c\/h3\u003e\n\u003cp\u003eThe manufacturer's brochures are available as PDF files:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0715\/1694\/6724\/files\/GENERAL_AIRSTAGE_CENTAURI_THERMOPOMPE_CENTRALE_AMUH12-48KUAS_BROCHURE_FR_anciennement_Fujitsu_AirGreen.pdf\" target=\"_blank\" rel=\"noopener\"\u003eBrochure in French (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0715\/1694\/6724\/files\/GENERAL_AIRSTAGE_CENTAURI_CENTRAL_HEAT_PUMP_AMUH12-48KUAS_BROCHURE_EN_formerly_Fujitsu_AirGreen.pdf\" target=\"_blank\" rel=\"noopener\"\u003eBrochure in English (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eTétreaultville and all of Montreal: a free quote to replace your electric furnace\u003c\/h3\u003e\n\n\u003cp\u003eFrom Tétreaultville to the rest of Montreal, and out to Laval, Longueuil, the North Shore and the South Shore, we handle this replacement from the visit to commissioning.

The old furnace is removed, and the AMUH48KUAS, whose cabinet measures 21 × 21 × 48 in. (W × D × H), connects to the supply \u003cstrong\u003eplenum\u003c\/strong\u003e and the \u003cstrong\u003ereturn air\u003c\/strong\u003e. In a basement, it normally goes in upflow; nothing prevents installing it downflow (UTD-DFMMB1 kit required) or in a horizontal left or right position, when the room calls for it.\u003c\/p\u003e\n\n\u003cp\u003eThe real test is the second floor. The AMUH48KUAS blower can move 1,600 CFM, against an external static pressure that the manufacturer places between 0.2 and 0.8 in. WC. That high airflow is only worth something if the ducts let it climb to the bedrooms. That is why the visit, where the duct layout and the number of grilles are set, reviews:\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003ethe main trunk and its branches, from the basement to the farthest rooms;\u003c\/li\u003e\n\u003cli\u003ethe risers climbing to the second floor inside the walls, sometimes narrow for the target airflow;\u003c\/li\u003e\n\u003cli\u003ethe upstairs \u003cstrong\u003ereturn air\u003c\/strong\u003e grilles, essential for air to circulate instead of sitting stagnant in the bedrooms;\u003c\/li\u003e\n\u003cli\u003ethe location of the wall control, which must read a temperature representative of the house;\u003c\/li\u003e\n\u003cli\u003ethe electrical service and the circuit the furnace used, since the heat pump and the backup kit will each have their own.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eLet's talk capacity, since it is what has to take over from the old furnace. The brochure breaks it down this way: in cooling, 45,500 BTU rated, modulating from 15,400 to 48,000 BTU; in heating, 51,000 BTU rated at 8.3 °C, modulating from 16,000 to 55,000 BTU. For the whole CENTAURI line, the manufacturer goes further and claims rated heating capacity that can exceed nominal capacity by up to 33%. In winter, the certified tests provide two separate points, presented as they are: 37,200 BTU, COP of 2.99, at −8 °C; 41,000 BTU, COP of 2.24, at −15 °C.\u003c\/p\u003e\n\n\u003cp\u003eThe AOUH48KUAS1 heats and cools down to −21 °C, and the brochure states \"no lockout\" at low temperature. In a large house, the \u003cstrong\u003ebackup heat\u003c\/strong\u003e kit is what makes the difference on the coldest nights and below that limit. The air handler offers several backup logics, which the refrigeration technician sets at commissioning; the compatible kit from the manufacturer, bought separately, gets its own dedicated supply, in addition to the 208\/230 V heat pump circuit (MCA 30 A, MOP 30 A).\u003c\/p\u003e\n\n\u003cp\u003eThe control deserves early thought, because none ships with the unit. In a multi-storey house, a wired wall controller, the KAGAMI UTY-RVRU or the UTY-RNRUZ5, keeps the control where the family is used to finding it, at the old thermostat's location if the spot is suitable. With the AIRSTAGE Mobile app, optional \u003cstrong\u003eWi-Fi\u003c\/strong\u003e also lets you adjust the setpoint from upstairs, without going down. A third-party 24 V thermostat can also connect through the UTY-TTRXZ1 interface, and a wireless remote works with its IR receiver kit. Service monitoring, finally, goes through a compatible controller.\u003c\/p\u003e\n\n\u003cp\u003eDown in the basement, the air handler stays at 34 dB(A) on low and reaches 51 dB(A) at full airflow. As for the outdoor unit (31 × 12.63 × 37 in.), its spec sheet shows 59 dB(A); we keep it away from bedroom windows, yours upstairs as well as the neighbour's. On the piping side, the refrigerant line (3\/8 and 5\/8 in.) can stretch to 75 m (246 ft); the precharge covers the first 30 metres (98 ft), the minimum length is 5 m (16 ft) and the allowed height difference reaches 30 m (98 ft): the unit can go in the backyard rather than against the mechanical room wall. The cable and drain follow the line, and the unit rests on a pad or a bracket.\u003c\/p\u003e\n\n\u003cp\u003eIn summer, it is the second floor again that benefits most, since it is where heat builds up. The same ducts then deliver cooled air, with dehumidification of 4.7 pints\/h according to the spec sheet. The values on AHRI certificate 217290597: a SEER2 of 17.0, an HSPF2 of 9.6 and an EER2 of 9.5, for an Inverter compressor running on R-32. The system also holds \u003cstrong\u003eENERGY STAR cold climate\u003c\/strong\u003e certification, under ID 4428950.\u003c\/p\u003e\n\n\u003cp\u003eAn access panel is built in for maintenance. The filter can sit on the optional 20 × 20 in. base, and it deserves watching: a loaded filter slows the air, and the rooms farthest from the unit are the first to notice. Leak detection is part of the air handler.\u003c\/p\u003e\n\n\u003cp\u003eFor the grant, Hydro-Québec gave this system $4,464 in its \u003cstrong\u003eLogisVert\u003c\/strong\u003e list of October 27, 2026, the highest amount in the CENTAURI series; the list in force on the date you apply is the one that counts. Warranty: 12 years from the manufacturer on the compressor and parts, 6 years on labour. AirGreen also offers it under the \"central heat pump\" name, with no technical difference at all.\u003c\/p\u003e\n\n\u003cp\u003eThis system suits the two-storey house whose ducts already serve both levels. If the second floor is heated by baseboards and has no grilles, the air handler will not be able to heat it without new ducts, and we assess that possibility with you. Finally, the 4 tons have to come out of the calculation made on site; if it points lower, we will propose a smaller system.\u003c\/p\u003e\n\n\u003ch3\u003eOfficial brochures\u003c\/h3\u003e\n\u003cp\u003eThe manufacturer's brochures are available as PDF files:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0715\/1694\/6724\/files\/GENERAL_AIRSTAGE_CENTAURI_THERMOPOMPE_CENTRALE_AMUH12-48KUAS_BROCHURE_FR_anciennement_Fujitsu_AirGreen.pdf\" target=\"_blank\" rel=\"noopener\"\u003eBrochure in French (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0715\/1694\/6724\/files\/GENERAL_AIRSTAGE_CENTAURI_CENTRAL_HEAT_PUMP_AMUH12-48KUAS_BROCHURE_EN_formerly_Fujitsu_AirGreen.pdf\" target=\"_blank\" rel=\"noopener\"\u003eBrochure in English (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eLaflèche, in Saint-Hubert: a free quote for your two-storey home\u003c\/h3\u003e\n\n\u003cp\u003eLaflèche, the rest of Saint-Hubert, all of Longueuil: we install this system there in place of an electric furnace, and our territory also covers Montreal, Laval, the North Shore and the South Shore.

An \u003cstrong\u003eelectric furnace\u003c\/strong\u003e there keeps its elements working non-stop. A GENERAL AIRSTAGE CENTAURI XLTH system, here in 30,000 BTU (2.5 tons), replaces it while keeping the duct system: the AMUH30KUAS multi-position air handler goes in its spot, and the AOUH30KUAH1 outdoor unit, a very-low-temperature \u003cstrong\u003eHeat Pump\u003c\/strong\u003e, supplies the heat down to −26 °C according to the manufacturer.\u003c\/p\u003e\n\n\u003cp\u003eThe twin Fujitsu AIRSTAGE CENTAURI XLTH page describes the same units, down to the model number.

Between −21 °C and −26 °C, a standard CENTAURI heat pump would already have handed over to the backup; the XLTH unit keeps heating. The \u003cstrong\u003eelectric backup heat kit\u003c\/strong\u003e installed in the air handler is then only needed on the worst nights.\u003c\/p\u003e\n\n\u003ch3\u003eGENERAL or Fujitsu AIRSTAGE: the same machine\u003c\/h3\u003e\n\n\u003cp\u003eThe XLTH unit's low-temperature heating range is published by the manufacturer's American subsidiary, also renamed on January 1, 2026.

The furnace comes out; the AMUH30KUAS, a 21 × 21 × 48 in. cabinet (W × D × H), moves into the freed-up space and ties into the \u003cstrong\u003eplenum\u003c\/strong\u003e and \u003cstrong\u003ereturn air\u003c\/strong\u003e after the ducts have been examined. Being multi-position, it can work upflow, downflow if you add the UTD-DFMMB1 kit, or lying on one side or the other. The grilles in the rooms stay put; duct routing and grille count are confirmed on site.\u003c\/p\u003e\n\n\u003cp\u003eTo judge this system in deep cold, here are the figures that matter. The AOUH30KUAH1 provides low-ambient heating down to −26 °C and cooling from −21 °C to 50 °C. The certification tests add two reference points, each measured under its own conditions: 21,000 BTU with a COP of 2.96 at −8 °C, and 34,000 BTU with a COP of 2.1 at −15 °C, two values we report as they are. On AHRI certificate 217895716, the system earns a SEER2 of 18.8, an HSPF2 of 10.0 and an EER2 of 12.2; ENERGY STAR recognizes it in its \u003cstrong\u003ecold climate\u003c\/strong\u003e category (ID 4511772).\u003c\/p\u003e\n\n\u003cp\u003eEven with an XLTH unit, you need backup. Below −26 °C, or when the house loses more heat than the heat pump can supply, the electric kit takes over. The air handler offers several \u003cstrong\u003ebackup heat\u003c\/strong\u003e logics; in Prévost, we favour a setting that lets the heat pump work as long as possible and calls on the elements last. Sold separately, the manufacturer's compatible kit gets its own power supply; the heat pump has its own as well, at 208\/230 V (MCA 21 A, MOP 25 A).\u003c\/p\u003e\n\n\u003cp\u003eIn the northern part of the territory, the outdoor unit's location is decided with snow in mind. The unit measures 39.31 × 12.60 × 37.01 in., and we place it:\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003eraised on a pad or a bracket, above the usual snow build-up on the property;\u003c\/li\u003e\n\u003cli\u003eaway from a roof slope or a gutter that dumps snow and ice;\u003c\/li\u003e\n\u003cli\u003eout of the path of the snowblower and the driveway snowbanks;\u003c\/li\u003e\n\u003cli\u003efar from bedroom windows, since the unit is rated at 57 dB(A).\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eTo reach the indoor unit, the refrigerant line, with its 3\/8 and 5\/8 in. tubes, travels with the cable and the drain, along a route set during the visit.\u003c\/p\u003e\n\n\u003cp\u003eFor air distribution, the AMUH30KUAS goes up to 1,000 CFM, with an allowable external \u003cstrong\u003estatic pressure\u003c\/strong\u003e of 0.2 to 0.8 in. WC. Those values only help if the return air keeps up, and it is a point we check every time on an old electric furnace duct system. Indoors, the air handler stays between 32 and 43 dB(A). In summer, it cools through the same ducts and dehumidifies at 3.47 pints\/h, according to the spec sheet.\u003c\/p\u003e\n\n\u003cp\u003eWe build an access panel in front of the filter. A refrigeration technician commissions the system and, at the same time, sets the backup logic; our company, which holds an RBQ licence, has AIRSTAGE Elite Plus installer status. The air handler includes its own leak detection system.\u003c\/p\u003e\n\n\u003cp\u003eNo control is supplied. The UTY-TTRXZ1 interface lets you keep a 24 V thermostat, provided it handles a heat pump and its backup. The other choices: a wired KAGAMI controller (UTY-RVRU or UTY-RNRUZ5), the AIRSTAGE Mobile app over \u003cstrong\u003eWi-Fi\u003c\/strong\u003e, or a wireless remote paired with an IR receiver kit. With a compatible controller, service monitoring is added.\u003c\/p\u003e\n\n\u003cp\u003eThe filter can sit in an optional 20 × 20 in. base. In the dead of winter, the system runs for long stretches: checking the filter more often than usual keeps it from choking the airflow just when the house needs it most.\u003c\/p\u003e\n\n\u003cp\u003eFor the \u003cstrong\u003eLogisVert\u003c\/strong\u003e grant, Hydro-Québec listed this system at $2,520 in its list of October 27, 2026; the list in force on the day you apply takes precedence. Under the manufacturer's warranty, the compressor and the parts get 12 years, labour gets 6. AirGreen also offers this system under the \"central heat pump\" name.\u003c\/p\u003e\n\n\u003cp\u003eThis size is meant for the house with ducts, heated today by an electric furnace, where the cold hits harder than in the city. The 2.5 tons are confirmed by a heat-loss calculation done on site; if the house needs more, a larger size exists in the same series, and we will tell you. Let us also be clear on one point: no heat pump makes the backup useless, it shrinks its role.\u003c\/p\u003e\n\n\u003ch3\u003eOfficial brochures\u003c\/h3\u003e\n\u003cp\u003eThe manufacturer's brochures are available as PDF files:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0715\/1694\/6724\/files\/GENERAL_AIRSTAGE_CENTAURI_THERMOPOMPE_CENTRALE_AMUH12-48KUAS_BROCHURE_FR_anciennement_Fujitsu_AirGreen.pdf\" target=\"_blank\" rel=\"noopener\"\u003eBrochure in French (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0715\/1694\/6724\/files\/GENERAL_AIRSTAGE_CENTAURI_CENTRAL_HEAT_PUMP_AMUH12-48KUAS_BROCHURE_EN_formerly_Fujitsu_AirGreen.pdf\" target=\"_blank\" rel=\"noopener\"\u003eBrochure in English (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003ePrévost and the North Shore: have your electric furnace assessed for free\u003c\/h3\u003e\n\n\u003cp\u003eOur crews travel to Prévost and throughout the North Shore, and the territory of AirGreen, an HVAC contractor, also extends to Laval, Montreal, Longueuil and the South Shore.

With this GENERAL AIRSTAGE CENTAURI XLTH system, in the 36,000 BTU (3-ton) size, the proportion flips: the AMUH36KUAS multi-position air handler connects to the existing ducts in place of the furnace, the AOUH36KUAH1 \u003cstrong\u003eHeat Pump\u003c\/strong\u003e handles most of the heating, and the electric elements stay only as reinforcement, in the form of an electric backup heat kit.\u003c\/p\u003e\n\n\u003cp\u003eThe same pair is sold under the Fujitsu AIRSTAGE CENTAURI XLTH name, with identical model numbers. No surprise there: both versions come from the same manufacturer, Fujitsu General Limited, renamed GENERAL Inc. on January 1, 2026, which gives them a single spec sheet and the same warranty.\u003c\/p\u003e\n\n\u003cp\u003eThe goal of this project fits in one sentence: cut the share of electric backup heat during winter without redoing the ducts. The XLTH outdoor unit, which heats down to −26 °C according to the manufacturer, is built for exactly that.\u003c\/p\u003e\n\n\u003ch3\u003eGENERAL or Fujitsu AIRSTAGE: the same machine\u003c\/h3\u003e\n\n\u003cp\u003eThe manufacturer has used the GENERAL name as a brand since 1946; since January 1, 2026, it is also the company's name. The company itself dates back to 1936, and 2026 marks 90 years since its founding. The Fujitsu brand is withdrawing little by little; in the meantime, the same factories produce a single machine that carries two names.\u003c\/p\u003e\n\n\u003cp\u003eThat is the reason for our two pages online: some customers still search for \"Fujitsu\", others already see \"GENERAL\".

At the certified test points, this system shows a COP of 2.9 at −8 °C, for 25,200 BTU, and a COP of 1.98 at −15 °C, for 41,000 BTU; these two measurements come from different test conditions, and we give them as they are.\u003c\/p\u003e\n\n\u003cp\u003eThe longer the heat pump heats through the season, the fewer hours the backup has to put in. That is where the XLTH unit stands out: it keeps up low-ambient heating down to −26 °C, where the standard CENTAURI's limit is −21 °C. Below that threshold, or when the house's demand exceeds what the heat pump supplies, the electric kit takes over. No figure promised on your bill from us, but the principle is sound.\u003c\/p\u003e\n\n\u003cp\u003eThe settings do the rest. The air handler offers several \u003cstrong\u003ebackup heat\u003c\/strong\u003e logics, and a thermostat set too eagerly can call on the elements well before the heat pump has reached its limits. At commissioning, the refrigeration technician picks the logic that delays the backup as far as comfort allows. If you keep your 24 V thermostat through the UTY-TTRXZ1 interface, it must be able to run a heat pump and its backup, and its own staging settings are checked at the same time.\u003c\/p\u003e\n\n\u003cp\u003eWithout touching the ducts, yes, but only if they keep up. The AMUH36KUAS has a maximum airflow of 1,207 CFM, and its external \u003cstrong\u003estatic pressure\u003c\/strong\u003e range runs from 0.2 to 0.8 in. WC. During the visit, we check whether the duct system can carry that airflow, whether the return air is large enough and whether joints are leaking in an unheated basement; the final layout and the number of grilles are set during that visit. If a correction is needed, you will know before the quote.\u003c\/p\u003e\n\n\u003cp\u003eMaintenance, the filter above all, is what protects that gain. A dirty filter cuts airflow, the heat pump struggles to deliver its heat, and the backup is likely to kick in more often. The routine stays simple:\u003c\/p\u003e\n\n\u003col\u003e\n\u003cli\u003echeck the filter through the access panel built in at installation, on the optional 20 × 20 in. base if there is one, and replace it as soon as it is loaded;\u003c\/li\u003e\n\u003cli\u003ekeep supply and return grilles clear of furniture and rugs;\u003c\/li\u003e\n\u003cli\u003eclear snow and leaves from the outdoor unit;\u003c\/li\u003e\n\u003cli\u003ehave the system's periodic maintenance done by a technician.\u003c\/li\u003e\n\u003c\/ol\u003e\n\n\u003cp\u003eSafety-wise, a leak detection system comes built into the air handler. Its sound level runs from 31 dB(A), at the lowest, to 46 dB(A); outside, the AOUH36KUAH1 is rated at 58 dB(A), and we choose its location with the patio and the neighbours in mind. When summer comes, the same equipment provides cooling across a −21 °C to 50 °C range, per the manufacturer, and dehumidifies at a rate of 3.82 pints\/h.\u003c\/p\u003e\n\n\u003cp\u003eOn certifications, AHRI certificate 217895717 gives a SEER2 of 18.3, an HSPF2 of 10.2 and an EER2 of 11.4. The system is approved \u003cstrong\u003eENERGY STAR cold climate\u003c\/strong\u003e, ID 4511773. Hydro-Québec's \u003cstrong\u003eLogisVert\u003c\/strong\u003e list tied $3,024 to it as of October 27, 2026; Hydro-Québec revises that list, and only the version on the day you apply counts. The manufacturer, for its part, covers the compressor and parts over a 12-year period, and labour over 6 years.\u003c\/p\u003e\n\n\u003cp\u003eNo control is included: besides the 24 V thermostat connected to the interface, you can opt for a wired KAGAMI controller (UTY-RVRU, UTY-RNRUZ5), for the AIRSTAGE Mobile app over \u003cstrong\u003eWi-Fi\u003c\/strong\u003e or for a wireless remote, which requires the IR receiver kit. Compatible controllers also give access to service monitoring. A refrigeration technician starts up the system, and AirGreen, an HVAC contractor, holds the AIRSTAGE Elite Plus installer designation. The same system is also offered by us as a \"central heat pump\".\u003c\/p\u003e\n\n\u003cp\u003eThis choice is aimed at the family whose ducts are sound and who wants electric backup to become the exception. It will not make the backup disappear: on the coldest nights, the kit will still work.

To replace it, this 4-ton GENERAL AIRSTAGE CENTAURI XLTH system, that is 48,000 BTU, brings together two units: the AMUH48KUAS, a multi-position air handler set in place of the furnace, and the AOUH48KUAH1, an outdoor \u003cstrong\u003eHeat Pump\u003c\/strong\u003e that heats down to −26 °C according to the manufacturer.

If each dwelling needs to set its own temperature, two separate systems are the better answer, and we will tell you so.

(W × D × H); once the ducts have been inspected, it is tied to the supply \u003cstrong\u003eplenum\u003c\/strong\u003e and the \u003cstrong\u003ereturn air\u003c\/strong\u003e. Thanks to its multi-position design, the AMUH48KUAS installs standing, upflow or downflow with the UTD-DFMMB1 kit, just as well as lying down toward the left or the right. The grilles on both floors stay where they are.\u003c\/p\u003e\n\n\u003cp\u003eFor a duct system serving two levels, everything starts with airflow. On the air side, the unit reaches 1,600 CFM at most, and the manufacturer sets its external \u003cstrong\u003estatic pressure\u003c\/strong\u003e range at 0.2 to 0.8 in. WC. In a duplex, the ducts running up to the upper dwelling are the longest, and the upstairs return air often decides comfort. We look at them during the visit, which is also when the final layout and grille count get fixed.\u003c\/p\u003e\n\n\u003cp\u003eIn deep cold, the AOUH48KUAH1 keeps heating down to −26 °C; its cooling range, for its part, runs from −21 °C to 50 °C. According to the certified file, it delivers 34,000 BTU, with a COP of 2.86, at −8 °C, and 51,000 BTU, with a COP of 1.96, at −15 °C: two distinct test conditions, each to be read on its own. Its seasonal ratings, recorded on AHRI certificate 217895718: SEER2 of 19.0, HSPF2 of 10.2, EER2 of 11.2. \u003cstrong\u003eENERGY STAR cold climate\u003c\/strong\u003e certification is granted to it under ID 4511774.\u003c\/p\u003e\n\n\u003cp\u003eCommissioning is the stage where a system this size is won or lost. The refrigeration technician who starts up the installation takes care of the following, among other things:\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003etesting the refrigerant line for leaks (3\/8 and 5\/8 in. tubes), then pulling a vacuum before releasing the R-32 refrigerant;\u003c\/li\u003e\n\u003cli\u003echecking the charge according to the manufacturer's instructions;\u003c\/li\u003e\n\u003cli\u003emeasuring the duct system's static pressure and comparing it with the manufacturer's range;\u003c\/li\u003e\n\u003cli\u003echoosing and programming the \u003cstrong\u003ebackup heat\u003c\/strong\u003e logic, then running the kit to validate it;\u003c\/li\u003e\n\u003cli\u003econnecting and testing the input\/output terminals in use, for example for an HRV, a humidifier or a fire alarm;\u003c\/li\u003e\n\u003cli\u003econfirming that the selected control works.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eBackup tuning deserves a closer look. A 4-ton system heating two floors needs serious reinforcement on the coldest nights, and below −26 °C, the kit takes over. The air handler offers several backup logics: the technician picks the one that lets the heat pump lead the heating and brings the elements in only when the house needs them. The manufacturer's compatible kit, sold separately, requires its own circuit; the system, for its part, needs a 208\/230 V supply (MCA 29 A, MOP 40 A). In a duplex, we also locate which electrical panel feeds the old furnace.\u003c\/p\u003e\n\n\u003cp\u003eThe 37.01 × 12.60 × 54.33 in. outdoor unit is tall and shallow, and its spec sheet shows 60 dB(A). In a duplex yard, it goes on a pad or a bracket, well clear of both dwellings' bedroom windows and balconies. The route of the refrigerant line, cable and drain is decided on site, based on how the yard is laid out.\u003c\/p\u003e\n\n\u003cp\u003eNo control comes with the system. The KAGAMI UTY-RVRU or UTY-RNRUZ5 wired wall controller goes in the dwelling whose temperature should serve as the reference; a 24 V thermostat compatible with a heat pump and its backup can also be kept through the UTY-TTRXZ1 interface. As options, there remain \u003cstrong\u003eWi-Fi\u003c\/strong\u003e with the AIRSTAGE Mobile app and the wireless remote fitted with its IR receiver kit; as for service monitoring, it goes through a compatible controller.\u003c\/p\u003e\n\n\u003cp\u003eIndoors, the air handler runs from 34 dB(A) at its lowest to 51 dB(A) at its highest. In summer, it cools both floors through the same ducts and removes 4.7 pints\/h of moisture, according to the spec sheet. A leak detection system is factory-integrated.\u003c\/p\u003e\n\n\u003cp\u003eThe filter is changed through a panel built for maintenance; as an option, it sits on a 20 × 20 in. base. In a duplex, it is best to decide at installation who looks after the filter: with 1,600 CFM to pass, it clogs quickly if forgotten.\u003c\/p\u003e\n\n\u003cp\u003eHydro-Québec set aside $4,080 for it in the October 27, 2026 version of its \u003cstrong\u003eLogisVert\u003c\/strong\u003e list; the list on the day you apply is still the one that applies. The manufacturer's warranty extends to 12 years for the compressor and parts, and 6 years for labour. AirGreen sells this same system as a \"central heat pump\" too.\u003c\/p\u003e\n\n\u003cp\u003eIn short, this size targets the duplex occupied by one family or the large house served by a single duct system in good condition. The heat-loss calculation, done at your home, confirms the 4 tons or not, and AirGreen, an HVAC contractor and AIRSTAGE Elite Plus installer, will tell you frankly if two systems would suit you better.\u003c\/p\u003e\n\n\u003ch3\u003eOfficial brochures\u003c\/h3\u003e\n\u003cp\u003eThe manufacturer's brochures are available as PDF files:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0715\/1694\/6724\/files\/GENERAL_AIRSTAGE_CENTAURI_THERMOPOMPE_CENTRALE_AMUH12-48KUAS_BROCHURE_FR_anciennement_Fujitsu_AirGreen.pdf\" target=\"_blank\" rel=\"noopener\"\u003eBrochure in French (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0715\/1694\/6724\/files\/GENERAL_AIRSTAGE_CENTAURI_CENTRAL_HEAT_PUMP_AMUH12-48KUAS_BROCHURE_EN_formerly_Fujitsu_AirGreen.pdf\" target=\"_blank\" rel=\"noopener\"\u003eBrochure in English (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eRenaud and all of Laval: a free quote for your duplex or large house\u003c\/h3\u003e\n\n\u003cp\u003eOur team travels to Renaud as well as the rest of Laval, and also covers Montreal, Longueuil, the North Shore and the South Shore.
