The manufacturer, formerly Fujitsu General Limited, has gone by the name GENERAL Inc. since January 1, 2026. Nothing separates the two versions: the same AHRI certificate 8071548, the same values published by the manufacturer, the same warranty of 12 years on the compressor, 12 years on parts and 6 years on labour.\u003c\/p\u003e\n\u003cp\u003eIn a four-bedroom house, it is rare for two people to want the same temperature. The youngest sleeps better when it is cool, the baby needs a milder room, the teenager closes the door and wants to decide alone, and the parents' bedroom is the one that heats up most under the roof. Four window air conditioners mean four hums in the night and four windows out of commission. A single compressor behind the house and one head per bedroom give everyone their own zone, without sacrificing anything on the façade.\u003c\/p\u003e\n\u003cp\u003eIn Brossard as in La Prairie, on the South Shore, many families live in four-bedroom cottages where everyone keeps their own hours: early bedtime for some, late nights for others, remote work in the guest room. The \u003cstrong\u003emulti-zone system\u003c\/strong\u003e follows those rhythms, one bedroom at a time.\u003c\/p\u003e\n\u003ch3\u003eGENERAL or Fujitsu AIRSTAGE: the same machine\u003c\/h3\u003e\n\u003cp\u003eA new name on a well-known line: that is all that sets this page apart from its Fujitsu twin. Fujitsu General, which came under the control of Paloma Rheem Holdings, owner of Rheem since 1988, in August 2025, has been called GENERAL Inc. since January 1, 2026. In Kawasaki, Japan, the head office and the R\u0026amp;D centre have not moved; the same factories make the same AIRSTAGE products, under the same model numbers, with the same warranty program. Until the Fujitsu brand has fully stepped back, the same AOU36RLXFZ1 outdoor unit can be found under both names.\u003c\/p\u003e\n\u003cp\u003eBoth pages stay online so that you can find your system whether you search for it under one name or the other, and the comparison table below confirms it value by value.

The system also removes up to 3.8 pints of water per hour from the air: in four closed bedrooms where people breathe all night long, that dehumidification counts as much as the temperature on the display.\u003c\/p\u003e\n\u003cp\u003eFor winter, here is what the values published by the manufacturer say: the AOU36RLXFZ1 outdoor unit delivers 21,400 BTU of heat at −8 °C and 22,600 BTU at −15 °C. The \u003cstrong\u003eCOP\u003c\/strong\u003e of 1.82 at −15 °C indicates that the heat pump produces 1.82 units of heat for each unit of electricity; with baseboards, that ratio is one to one. The \u003cstrong\u003eHSPF2\u003c\/strong\u003e of 8.6 gives the average of that performance over the whole winter. Heating is guaranteed down to −15 °C, the equivalent of a genuinely cold night on the South Shore. Since this model is not certified for cold climates, the bedroom baseboards stay in place and supplement the heat pump when the mercury drops further.\u003c\/p\u003e\n\u003cp\u003eEach of the 4 zones has its own set point, adjusted in the bedroom itself. The children can have a cooler bedroom than their parents, and the guest room can stay on standby until the next visit. The \u003cstrong\u003eInverter compressor\u003c\/strong\u003e adapts its speed to the total demand: at bedtime, when all four heads call for cooling, it ramps up, then it slows back down once the bedrooms reach temperature.

What changed is the manufacturer's name: Fujitsu General Limited became GENERAL Inc. on January 1, 2026.\u003c\/p\u003e\n\u003cp\u003eWe built this page around a case we see often in Longueuil and Saint-Hubert: the fourplex whose owner wants to cool and heat four units without lining up four compressors along the back wall.

One outdoor unit to set, one base, one electrical circuit, one outdoor machine to maintain, instead of four separate machines each aging on its own schedule. The heads, for their part, stay independent: every tenant sets their own temperature, airflow and schedule with their own remote. The mode, heating or cooling, is shared by the outdoor unit, as with any multi-zone (multi-split); in a building, it follows the season anyway.\u003c\/p\u003e\n\u003ch3\u003eGENERAL or Fujitsu AIRSTAGE: the same machine\u003c\/h3\u003e\n\u003cp\u003eIn August 2025, Paloma Rheem Holdings, owner of Rheem since 1988, acquired Fujitsu General Limited. On January 1, 2026, the company took the name GENERAL Inc. The head office and the R\u0026amp;D centre stayed in Kawasaki, Japan; the factories, the AIRSTAGE products, the model numbers and the warranty program did not move. The Fujitsu brand is being phased out and, during the transition, the same machine is sold under both names. In Canada, Rheem Canada has handled sales since February 2026, and Groupe Master remains our distributor.\u003c\/p\u003e\n\u003cp\u003eThat is why we keep both pages online.

The 45,000 BTU Inverter compressor posts a \u003cstrong\u003eSEER2\u003c\/strong\u003e of 20.0 in cooling, an EER2 of 10.5 and an \u003cstrong\u003eHSPF2\u003c\/strong\u003e of 9.2 in heating. The HSPF2 sums up the whole heating season: the higher it is, the more heat is delivered per kilowatt-hour consumed. The COP, on the other hand, is a snapshot taken at one precise temperature. At −8 °C, the manufacturer publishes 28,200 BTU\/h; at −15 °C, it publishes 31,400 BTU\/h with a COP of 1.88, which means almost twice the heat of an electric baseboard for the same electricity. \u003cstrong\u003eGuaranteed heating\u003c\/strong\u003e goes down to −15 °C, which covers most of the winter in Longueuil; below that point, each unit's baseboards take over.\u003c\/p\u003e\n\u003cp\u003eConcretely, for a fourplex, here is what that gives you:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eOne setpoint per zone: every unit has its own remote, its own temperature and its own schedule, without going through the neighbour.\u003c\/li\u003e\n\u003cli\u003eFour 9,000 BTU heads on a 45,000 BTU compressor: there is margin left for the cold mornings when all four units call at the same time.\u003c\/li\u003e\n\u003cli\u003eDehumidification of 3.8 pints per hour in cooling, for units that stay dry in July.\u003c\/li\u003e\n\u003cli\u003eAn outdoor sound level of 55 dB(A): a single source of noise in the yard, instead of four.\u003c\/li\u003e\n\u003cli\u003eOptional Wi-Fi, handy for the owner who wants to keep an eye on a vacant unit between two tenants.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe 9,000 + 9,000 + 9,000 + 9,000 BTU configuration is the one on this page; it is not set in stone. This compressor accepts up to 5 zones and five models of wall-mounted heads: ASU7RLF1 (7,000 BTU), ASU9RLF1 (9,000 BTU), ASU12RLF1 (12,000 BTU), ASU15RF1 (15,000 BTU) and ASU18RLF (18,000 BTU). A corner unit, more exposed to the wind, can receive a 12,000 BTU head while the other three keep 9,000 BTU; a fifth head can serve an owner's room in the basement or a common area. We choose each head with you, unit by unit, after the visit.\u003c\/p\u003e\n\u003cp\u003eInstallation by AirGreen on a fourplex follows a simple logic:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eA single \u003cstrong\u003eoutdoor unit\u003c\/strong\u003e, the AOU45RLXFZ, set on a base or a clear bracket at the back of the building, where it gets in the way of neither a balcony nor a bedroom window.\u003c\/li\u003e\n\u003cli\u003eOne \u003cstrong\u003erefrigerant line\u003c\/strong\u003e per head: four identified lines, grouped in a raceway along the back wall, with a single wall penetration per unit.\u003c\/li\u003e\n\u003cli\u003eEach head mounted high on a wall of the unit's main room, with the clearance needed for the air to circulate through the whole space.\u003c\/li\u003e\n\u003cli\u003eGravity drainage for each head, to the outside or to a drain, without a pump when the slope allows it.\u003c\/li\u003e\n\u003cli\u003eA single dedicated electrical circuit for the outdoor unit, instead of four.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eMaintenance comes down to two things. The \u003cstrong\u003eindoor filters\u003c\/strong\u003e of each head come out without tools and rinse under water; in a rental building, we show the move to each tenant at commissioning. After that, a regular visit by our refrigeration technician for the outdoor unit, the pressures and the drains is enough. A single outdoor unit to inspect also means a single visit for the whole building.\u003c\/p\u003e\n\u003cp\u003eA frank word about grants: the AOU45RLXFZ outdoor unit is not listed on Hydro-Québec's LogisVert list and does not carry the ENERGY STAR certification. So we promise you no amount for this model. Its argument lies elsewhere: the proven \u003cstrong\u003eR-410A\u003c\/strong\u003e platform of the RLXFZ series, a single compressor for four units and a warranty of 12 years on the compressor and parts, 6 years on labour, identical to the one offered under the Fujitsu name.\u003c\/p\u003e\n\u003cp\u003eThis 4-zone is made for the owner-occupant or the small investor in Longueuil, in Saint-Hubert or elsewhere on the South Shore who wants a single system to manage, a clean yard and four tenants who set their own comfort. It also suits a triplex with a commercial space on the ground floor, or a large house divided into two units that each have two living areas. If the building is heated with electricity and you insist on a heat pump that keeps its full capacity well below −15 °C, ask us about the same manufacturer's certified cold-climate series; we will tell you frankly which one fits your building.\u003c\/p\u003e\n\u003ch3\u003eA GENERAL AIRSTAGE multi-zone for your fourplex in Longueuil, in Saint-Hubert and everywhere on the South Shore\u003c\/h3\u003e\n\u003cp\u003eAirGreen is an AIRSTAGE Elite Plus installer and an HVAC contractor holding an RBQ licence.

The head office and the R\u0026amp;D centre have not left Kawasaki, Japan, and nothing has changed either on the side of the factories, the AIRSTAGE range, the model numbers or the warranty.

That peak is what goes to work on Friday evening, when the cottage, kept cool all week, has to warm back up in four rooms at the same time.

Same AOUH36KWAS4, same configuration, same installer.\u003c\/p\u003e\n\n\u003cp\u003eFour closed bedrooms means a heating load split four ways, and the compressor has to follow every door that closes. Here is what NEEP (ashp.neep.org) has certified under AHRI number 215447689: at −8 °C, 23,600 BTU\/h and a \u003cstrong\u003eCOP\u003c\/strong\u003e of 3.1, with a peak of 29,000 BTU\/h; at −15 °C, 24,000 BTU\/h and a COP of 2.2. Its heating remains guaranteed down to −15 °C.\u003c\/p\u003e\n\n\u003cp\u003eA typical January morning on the North Shore hovers around −8 °C; at that temperature, the COP of 3.1 gives an efficiency a little more than three times that of a baseboard, which turns each unit of electricity into a single unit of heat. The cold nights of mid-January drop toward −15 °C, and the system loses nothing there compared with −8 °C. Lower still, the bedroom baseboards top up. The \u003cstrong\u003eHSPF2\u003c\/strong\u003e of 10.0 gives the measure of the entire heating season; it pairs with the \u003cstrong\u003eSEER2\u003c\/strong\u003e of 22.0, its summer counterpart, and with the EER2 of 12.0.\u003c\/p\u003e\n\n\u003cp\u003eOn efficiency, ENERGY STAR awards it the Most Efficient designation: it counts among the most efficient units of the year. The cold-climate designation is missing from its ENERGY STAR listing; its certified performance at −15 °C, however, is there, with the figures to back it up.\u003c\/p\u003e\n\n\u003cp\u003eThe \u003cstrong\u003eInverter\u003c\/strong\u003e compressor goes down to 11,000 BTU\/h, the minimum NEEP certifies for it: it modulates its speed according to the number of bedrooms calling rather than running flat out. Outside, the outdoor unit is measured at 56.0 dB(A), and we place it on the side opposite the bedrooms. As for the refrigerant, it is \u003cstrong\u003eR-32\u003c\/strong\u003e: a global warming potential of 675 according to ENERGY STAR, where R-410A shows 2,088.\u003c\/p\u003e\n\n\u003cp\u003eFour 7,000 BTU heads, one per bedroom: that is the configuration on this page. A larger master bedroom or a very sunny office can justify another capacity, chosen with us among the compatible indoor units:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eASUH07KPAS\u003c\/strong\u003e, 7,000 BTU, the standard bedroom;\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eASUH09KPAS\u003c\/strong\u003e, 9,000 BTU, the parents' bedroom;\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eASUH12KPAS\u003c\/strong\u003e, 12,000 BTU, a suite with an ensuite bathroom;\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eASUH15KPAS\u003c\/strong\u003e, 15,000 BTU, a bedroom above the garage, more exposed to the cold;\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eASUH18KPAS\u003c\/strong\u003e, 18,000 BTU, if one of the zones becomes a large living space;\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eASUH24KPAS\u003c\/strong\u003e, 24,000 BTU, for the largest of the rooms.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eFour zones is the maximum for this compressor: with this configuration, it is full.

We place each head on an exterior wall of its bedroom, bring each line out directly behind the head, and gather them in a single line cover that runs down a secondary wall to the outdoor unit. For a bedroom with no wall facing the back or the side, other routes exist; we examine them on site with you.\u003c\/p\u003e\n\n\u003cp\u003eThe outdoor unit goes on a stand that keeps it above the snow, on one side or at the back of the house, where it gets in the way of neither the windows nor the view from the street. The condensate drains flow by gravity to the outside; a condensate pump is needed only for a head with no direct access to an exterior wall. A dedicated electrical circuit powers it from the panel. And since there are no ducts at all, there is no bulkhead in the ceilings and no grille in the floors.\u003c\/p\u003e\n\n\u003cp\u003eWith four heads, maintenance is shared: each occupant takes out the \u003cstrong\u003eindoor filters\u003c\/strong\u003e of their own bedroom, without tools, and rinses them with water. That is the habit that keeps airflow and efficiency up. The outdoor unit, for its part, gets cleared of snow in winter, and a periodic visit from a refrigeration technician covers the R-32 charge, the coil and the drains.\u003c\/p\u003e\n\n\u003cp\u003eAccording to Hydro-Québec's LogisVert list dated October 27, 2026, this system is associated with an amount of $1,180.

What changed is the name on the box: Fujitsu General Limited became GENERAL Inc. on January 1, 2026, and the machine our refrigeration technicians pull out of the truck is exactly the one they already know.\u003c\/p\u003e\n\n\u003cp\u003eWe picked it for one specific case: the fourplex in Montréal-Nord or Saint-Léonard, four apartments stacked or side by side, four tenants who do not want the same temperature, and an owner who does not want four outdoor units lined up in the back lane. One outdoor unit on the roof or on the ground, one 7,000 BTU wall-mounted head per apartment, one setpoint per tenant. The 45,000 BTU compressor accepts up to 5 zones, which leaves a free port for a fifth space later on.\u003c\/p\u003e\n\n\u003cp\u003eFour 7,000 BTU heads is the right format for a typical plex apartment: the head goes in the main room, blows toward the hallway, and the tenant sets the temperature to taste. In summer, everyone cools their own apartment; in winter, everyone heats their own way and the existing electric baseboards stay in place as backup on the coldest days. For the owner, that means one machine to maintain, one electrical feed and one maintenance visit to plan instead of four.\u003c\/p\u003e\n\n\u003ch3\u003eGENERAL or Fujitsu AIRSTAGE: the same machine\u003c\/h3\u003e\n\n\u003cp\u003eThe name change comes from a transaction, not from a new product line. In August 2025, Paloma Rheem Holdings, owner of Rheem since 1988, acquired Fujitsu General Limited. On January 1, 2026, the company became GENERAL Inc.: same head office and same research centre in Kawasaki, Japan, same factories, same AIRSTAGE products, same model numbers, same warranty program. The GENERAL name is nothing new either: the brand has been in use since 1946, and the company, founded in 1936, marks the 90th anniversary of its founding in 2026. Since February 2026, Rheem Canada has handled sales in this country, and Groupe Master remains our distributor, as before.\u003c\/p\u003e\n\n\u003cp\u003eDuring the transition, the Fujitsu brand is gradually disappearing from the packaging and the same machine circulates under both names. That is why we keep both pages online: you may land here after searching for \"Fujitsu Aquila 4 zones\" or after reading \"GENERAL\" on a label, and in both cases you are looking at the same AOUH45KWAS5 with the same AHRI certificate.

Same warranty, same AirGreen installation, same service after the install; simply pick the page that carries the name you know.\u003c\/p\u003e\n\n\u003cp\u003eLet's talk performance, because that is where this compressor stands out. The values that follow come from NEEP (ashp.neep.org), under AHRI certificate 215735280, not from a brochure: \u003cstrong\u003e31,000 BTU\/h of rated capacity at −8 °C\u003c\/strong\u003e, with a COP of 2.96 and measured peaks of 41,000 BTU\/h, then \u003cstrong\u003eup to 36,000 BTU\/h at −15 °C\u003c\/strong\u003e with a COP of 2.14. COP is the ratio between heat delivered and electricity consumed: a COP of 2.96 means every kilowatt-hour you pay Hydro-Québec comes back as nearly three in heat inside your apartments. At −15 °C, an electric baseboard still returns one for one; this heat pump still returns more than two.\u003c\/p\u003e\n\n\u003cp\u003eThe SEER2 of 22.0 and the EER2 of 12.0 describe summer: the higher the number, the less cooling costs in electricity for the same comfort. The \u003cstrong\u003eHSPF2 of 10.0\u003c\/strong\u003e describes the whole winter, not a single day: it is the total heat delivered over the season divided by the total electricity consumed, measured under the most recent standard. That combination earns the model the \u003cstrong\u003eENERGY STAR Most Efficient\u003c\/strong\u003e label on top of its cold-climate designation. Heating is guaranteed down to −15 °C; below that, the apartment's electric backup takes over for the harshest January nights.\u003c\/p\u003e\n\n\u003cp\u003eThe rest of the comfort comes from the Inverter compressor. Its certified minimum capacity is 12,000 BTU\/h: when a single apartment calls, it slows down instead of stopping and restarting, which keeps the temperature steady and avoids the short cycles that wear a machine out. Each zone has its own setpoint and its own remote; one tenant can sleep cool while the neighbour works warm. One rule to know: all the heads connected to the same compressor run in the same mode, heating or cooling, which bothers no one in Quebec, where everyone heats in the same month.\u003c\/p\u003e\n\n\u003cp\u003eThe configuration on this page brings together four 7,000 BTU wall-mounted heads, but nothing is locked in: you choose your indoor units with us, room by room, among the models compatible with the AOUH45KWAS5:\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eASUH07KPAS\u003c\/strong\u003e, 7,000 BTU: bedroom, office, small plex living room.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eASUH09KPAS\u003c\/strong\u003e, 9,000 BTU: medium living room or a very open apartment.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eASUH12KPAS\u003c\/strong\u003e, 12,000 BTU: open kitchen and living area.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eASUH15KPAS\u003c\/strong\u003e, 15,000 BTU, and \u003cstrong\u003eASUH18KPAS\u003c\/strong\u003e, 18,000 BTU: large apartments or the owner's unit across two connecting rooms.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eASUH24KPAS\u003c\/strong\u003e, 24,000 BTU: a full, open-plan floor.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eThe compressor accepts up to 5 zones. A fourplex with one apartment larger than the others can therefore take three 7,000 BTU heads and one 12,000 BTU head, and keep a fifth port for a basement bedroom or a workshop. We size each head on site, room by room, taking orientation, windows and insulation into account, not from a generic chart.\u003c\/p\u003e\n\n\u003cp\u003eAn AirGreen installation follows a simple logic: \u003cstrong\u003ea single outdoor unit\u003c\/strong\u003e, then \u003cstrong\u003eone refrigerant line per head\u003c\/strong\u003e. In a plex, the outdoor unit most often goes on the flat roof or on a ground stand at the back, where it bothers neither the parking nor the neighbours; it is 37 inches wide, runs at 56.0 dB(A) and needs clearance for air and for snow. From there, four insulated lines run up or down to the apartments, usually in a cover along the back wall, each with its control cable. Each wall-mounted head is set high on a wall that faces outside or close to where the lines rise, and its condensate drain flows by gravity to the outside or to a pump when the slope is not enough. The electrician connects a single feed for the compressor; that is a point to settle in the lease, since the heating for all four apartments goes through one meter.\u003c\/p\u003e\n\n\u003cp\u003eDay-to-day maintenance is within the tenants' reach: each head has washable \u003cstrong\u003eindoor filters\u003c\/strong\u003e that slide out by hand and rinse under warm water; a clean filter keeps the airflow and the efficiency. The rest belongs to the refrigeration technician: checking the R-32 charge, cleaning the outdoor coil, inspecting drains and connections. R-32 itself is an argument: its global warming potential is 675, versus 2,088 for R-410A according to ENERGY STAR.\u003c\/p\u003e\n\n\u003cp\u003eOn the financial side, the AOUH45KWAS5 is listed on Hydro-Québec's \u003cstrong\u003eLogisVert\u003c\/strong\u003e list with an amount of $3,720 as of today. The eligibility conditions are Hydro-Québec's and vary with the type of building; we check them with you when we prepare the quote rather than promising a figure blindly. The warranty is the AIRSTAGE program's: 12 years on the compressor, 12 years on parts and 6 years on labour. Wi-Fi control is offered as an option, head by head, for tenants who want to adjust their apartment from their phone.\u003c\/p\u003e\n\n\u003cp\u003eThis system is made for the fourplex owner who wants to settle the comfort of all four apartments in one go, without ducts, without drilling the back wall four times for four outdoor units, and without hearing four compressors run. It also suits the three-generation home or the large Saint-Léonard house with four bedrooms far apart from one another, where a single central unit would never satisfy everyone. And since it is the same machine as the Fujitsu version, you give up nothing in the transition: same parts, same trained technicians, same distribution network.\u003c\/p\u003e\n\n\u003ch3\u003eFree quote in Montréal-Nord, Saint-Léonard and across Greater Montreal\u003c\/h3\u003e\n\n\u003cp\u003eWe install this multi-zone system in Montreal, Laval, Longueuil, on the North Shore and on the South Shore, and we know the flat roofs and back lanes of Montréal-Nord and Saint-Léonard.

This compressor accepts a maximum of 4 zones: the configuration on this page uses them all, and that is what makes it possible to cover every bedroom without compromise.\u003c\/p\u003e\n\n\u003ch3\u003eGENERAL or Fujitsu AIRSTAGE: the same machine\u003c\/h3\u003e\n\n\u003cp\u003eGENERAL Inc. has been the new name of Fujitsu General Limited since January 1, 2026. The change follows the acquisition of the company by Paloma Rheem Holdings, owner of Rheem since 1988, in August 2025. For you, nothing moves: the head office and the R\u0026amp;D centre are still in Kawasaki, Japan, the manufacturing lines have not changed, and the AIRSTAGE products keep their model numbers and warranty program. The GENERAL name is not a recent invention: it has served as a brand since 1946, and the company itself, founded in 1936, reaches 90 years in 2026. In Canada, sales have been under Rheem Canada since February 2026, and our distributor remains Groupe Master.\u003c\/p\u003e\n\n\u003cp\u003eThe Fujitsu name will gradually disappear from the packaging; in the meantime, the same machine comes under two labels. We chose to leave both pages online and to compare them in the table below, so the decision rests on the system, not on the logo.\u003c\/p\u003e\n\n\u003ctable class=\"tp-compare\"

Four 7,000 BTU heads on a 36,000 BTU compressor is a pairing that leaves some margin when all four bedrooms call at the same time on a February night.\u003c\/p\u003e\n\n\u003cp\u003eCOP compares the heat delivered with the electricity consumed. At 3.33, an all-electric house gets more than three kilowatt-hours of heat for every kilowatt-hour paid for, where its baseboards give one. Even at −26 °C, the system does better than the baseboard. Over the whole season, the \u003cstrong\u003eHSPF2 of 10.0\u003c\/strong\u003e sums up this heating efficiency; in cooling, the \u003cstrong\u003eSEER2 of 22.0\u003c\/strong\u003e and the EER2 of 13.0 play the same role. Finally, the Inverter compressor slows down to 12,000 BTU\/h, its certified minimum capacity, when only some of the bedrooms ask for heat.\u003c\/p\u003e\n\n\u003cp\u003eAt every quote, we are asked what happens to the ground floor when the four zones go to the bedrooms. There are two approaches, and we present them frankly. If the living room and the kitchen already have their own wall-mounted heat pump, or if the baseboards are enough there, the four zones go to the four bedrooms. Otherwise, we often split the system between three bedrooms and the open-plan ground floor, and the fourth bedroom, often the guest room, stays on its baseboard. Either way, the four heads share the same mode, heating or cooling, which naturally follows the seasons of a family home.\u003c\/p\u003e\n\n\u003cp\u003eThe configuration on this page puts a 7,000 BTU head in each zone, a size suited to a closed bedroom of ordinary size.

We place each \u003cstrong\u003ewall-mounted head\u003c\/strong\u003e high up, preferably on an exterior wall, so the air runs along the ceiling instead of falling onto the bed. The \u003cstrong\u003eoutdoor unit\u003c\/strong\u003e (37 inches wide, 56.0 dB(A)) goes on the ground, on a raised pad, on the side of the house farthest from bedroom windows, yours and the neighbours' alike.

For condensate, gravity is enough in most bedrooms; a small condensate pump completes the drainage of a head placed on an interior wall. The compressor needs its own circuit at the panel; in a house where the water heater, the range and the baseboards already draw on the electrical service, the electrician confirms the available capacity during the visit.\u003c\/p\u003e\n\n\u003cp\u003eFour bedrooms, four sets of \u003cstrong\u003eindoor filters\u003c\/strong\u003e.
