In a properly sized home, the heat pump therefore provides most of the heating for most of the winter in \u003cstrong\u003eLaval\u003c\/strong\u003e as in \u003cstrong\u003eLongueuil\u003c\/strong\u003e, and keeps contributing during cold snaps. When the home's demand exceeds what the outdoor unit supplies, electric backup takes over; we size it from the on-site assessment and list it in the quote.\u003c\/p\u003e\u003ch3\u003eR-454B, the new generation of refrigerant\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eR-454B\u003c\/strong\u003e is gradually replacing the previous-generation refrigerant in new central heat pumps. If it leaks, its effect on global warming is much lower, and manufacturers have adopted it for their new product lines. For the homeowner, this means a system designed for current standards rather than an older-generation unit.\u003c\/p\u003e\u003cp\u003eThis refrigerant belongs to the A2L class, known as mildly flammable. Its installation follows specific requirements, especially for circuit tightness and for the safety of the indoor unit.

A single heat pump takes care of both seasons.\u003c\/p\u003e\u003cp\u003eThis size assumes a reasonable building envelope. If the attic is poorly insulated or the windows are original in an older house, heat loss may justify the next size up. Conversely, going too big in a small home leads to short cycles, temperature differences and poor dehumidification in summer. A room-by-room on-site assessment lets us decide on facts rather than on an estimate.\u003c\/p\u003e\u003ch3\u003eThe D5FUAA cabinet and air distribution\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eD5FUAAH18XAK\u003c\/strong\u003e cabinet is the system's indoor unit: it contains the coil, where the refrigerant releases or absorbs heat, and the blower that moves air through the house. It is installed where the old furnace stood, usually in the basement, and connects to the existing supply plenum and air return.\u003c\/p\u003e\u003cp\u003eA heat pump delivers its heat at a gentler temperature than a furnace; it makes up for it by circulating air longer. The quality of the duct system therefore matters as much as the unit. We check that the main \u003cstrong\u003educts\u003c\/strong\u003e are neither crushed nor poorly connected, that each room has a supply register and that the air return is sufficient.

On a mild spring day, it runs slowly; on a January morning, it speeds up. You feel the result in the house: a steady temperature, without the bursts of hot air followed by long pauses of a conventional furnace, and quieter operation, since a unit running slowly makes less noise than one that starts at full power.\u003c\/p\u003e\u003cp\u003eVariable speed also serves efficiency: most of the time, the heat pump runs at part load, where its efficiency is at its best.

In summer, the system then runs for long periods at low speed: air passing over the cold coil loses its moisture, the temperature stays steady, and the house is cool without being clammy.

Even on the coldest nights of a \u003cstrong\u003eMontreal\u003c\/strong\u003e winter, the heat pump therefore still delivers one and a half times the heat it uses in electricity.\u003c\/p\u003e\u003cp\u003eA house may still lose more heat than the outdoor unit supplies at those temperatures. Electric backup, usually housed in the cabinet, then supplements the heating. We size it from the on-site assessment and set the thermostat so it only comes on when needed. With a heat pump that keeps its capacity, those backup hours are fewer.\u003c\/p\u003e\u003ch3\u003eWhich homes it suits\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003e2.5-ton\u003c\/strong\u003e size, or \u003cstrong\u003e30,000 BTU\/h\u003c\/strong\u003e, often suits a two-storey cottage, a large bungalow with a finished basement or a wind-exposed house on the outskirts, on the \u003cstrong\u003eNorth Shore\u003c\/strong\u003e or the \u003cstrong\u003eSouth Shore\u003c\/strong\u003e.

At \u003cstrong\u003e1.5 tons\u003c\/strong\u003e, it is one of the smallest central heat pump sizes: it is meant for homes where a bigger unit would run in short bursts, heat the bedrooms poorly and leave humidity in the air in summer.\u003c\/p\u003e\u003ch3\u003eThe homes that suit 1.5 tons\u003c\/h3\u003e\u003cp\u003eThis size suits compact homes that already have their ducts: a townhouse, a small well-insulated bungalow, a renovated semi-detached house, or the upper floor of a duplex with its own duct system and its own air handler. It also suits recent homes with a tight envelope, where the heating load is often lower than people expect.\u003c\/p\u003e\u003cp\u003eFloor area alone does not settle it. Attic and wall insulation, the age of the windows, the orientation of the house and the amount of glazing change the load a great deal. An unrenovated house from the sixties may need the next size up, even if it is small. That is why we run a room-by-room \u003cstrong\u003eon-site assessment\u003c\/strong\u003e before proposing a size, rather than copying the size of the old unit.\u003c\/p\u003e\u003ch3\u003eWhy an oversized unit hurts comfort\u003c\/h3\u003e\u003cp\u003eThe habit of choosing \"a little bigger, to be safe\" dates from the air conditioner era. With a central heat pump, it costs comfort. An oversized unit reaches the set point in a few minutes, stops, then starts again: these short cycles wear the components, leave temperature differences between rooms and shut the cooling off before the coil has removed the humidity. The house is cool, but clammy.\u003c\/p\u003e\u003cp\u003eA properly sized system, on the other hand, runs in longer cycles. Air moves through the ducts for longer, rooms far from the cabinet get their share and the coil has time to dry the air. In a small home, the 1.5-ton size is often the one that allows this steady operation, in winter as in summer.\u003c\/p\u003e\u003ch3\u003eThe FJMA4X cabinet, in place of the old furnace\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eFJMA4X18L0AB\u003c\/strong\u003e cabinet is the system's indoor unit. It houses the coil, where the refrigerant releases or absorbs heat, and the blower that moves air through the \u003cstrong\u003educts\u003c\/strong\u003e. It goes where the old electric furnace stood, usually in the basement or a utility closet, and connects to the existing supply plenum and return air.\u003c\/p\u003e\u003cp\u003eThe cabinet can also receive \u003cstrong\u003ebackup electric heating elements\u003c\/strong\u003e. They only come on when the heat pump alone is no longer enough, in deep cold or during a defrost. Their capacity is chosen from the on-site assessment and the capacity of the electrical panel; we list it in the quote.\u003c\/p\u003e\u003ch3\u003eHow a heat pump heats a home\u003c\/h3\u003e\u003cp\u003eA heat pump does not produce heat, it moves it. In winter, the refrigerant flows through the outdoor unit and absorbs the heat contained in the air, even cold air. The compressor raises its temperature by compressing it, then the refrigerant releases that heat to the cabinet's coil, and the blower distributes it through the ducts. In summer, a reversing valve turns the circuit around: the heat of the house is sent outdoors.\u003c\/p\u003e\u003cp\u003eBecause it moves heat instead of producing it with a resistance, a heat pump delivers more energy than it uses as long as the outdoor air is not too cold. The system runs on \u003cstrong\u003eR-410A\u003c\/strong\u003e, a refrigerant that refrigeration technicians know well.\u003c\/p\u003e\u003ch3\u003eWhat the certificate shows for winter\u003c\/h3\u003e\u003cp\u003eThe certificate lists \u003cstrong\u003e10,100 BTU\/h at -8 °C\u003c\/strong\u003e (17 °F) and \u003cstrong\u003e7,700 BTU\/h at -15 °C\u003c\/strong\u003e (5 °F), with a \u003cstrong\u003eCOP of 1.88\u003c\/strong\u003e at -15 °C. The two points are measured separately; we report each one as published, without extrapolating.\u003c\/p\u003e\u003cp\u003eCompared with the nominal size of 18,000 BTU, these figures represent about 56% at -8 °C and 43% at -15 °C. A heat pump's capacity drops as the cold deepens, while the home's needs rise. There is therefore an outdoor temperature below which the heat pump is no longer enough on its own: the cabinet's backup elements then supply the missing share, and switch off as soon as the heat pump can carry the load again.\u003c\/p\u003e\u003cp\u003eThese figures come from certificate \u003cstrong\u003eAHRI 210998953\u003c\/strong\u003e, as published in the AHRI certification directory.\u003c\/p\u003e\u003ch3\u003eReading SEER2, EER2, HSPF2 and COP\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003cstrong\u003eSEER2 (14.3)\u003c\/strong\u003e: seasonal cooling efficiency, calculated over a typical summer.

Return air often comes back through one or two large grilles in the hallway or living room. If the basement is finished, a few grilles serve it as well.\u003c\/p\u003e\u003cp\u003eThis duct system was often designed for an electric furnace, which pushes a small amount of very hot air. A heat pump delivers milder air, in larger quantity and for longer. The ducts must therefore let enough air through, especially on the return side.

A finer filter captures more particles, but it also restricts the air; if it is too restrictive, it reduces the airflow and the heat pump's efficiency. During the visit, we look at the existing filter rack and propose a format that filters well without choking the system. A filter needs care: checked every month in season, it is replaced as soon as it is loaded.\u003c\/p\u003e\u003cp\u003eA useful reminder: a central heat pump recirculates the air of the house, it does not bring in fresh air.

In winter, the refrigerant captures heat from the outdoor air in the outdoor unit; the compressor concentrates it; the cabinet's coil releases it to the air that the blower distributes through the ducts. In summer, a reversing valve turns the cycle around and the heat of the house is released outdoors.\u003c\/p\u003e\u003cp\u003eThe air coming out of the grilles is warm rather than very hot, and the system runs longer at a time than an electric furnace.

We avoid roof drips, corners where snow piles up, dryer vents and, as far as possible, bedroom windows.\u003c\/p\u003e\u003cp\u003eAccess matters too: the unit must stay clear for annual maintenance.

That is what a central system with an air handler allows: one unit, two heat sources, and a thermostat that makes the heat pump work first.\u003c\/p\u003e\u003cp\u003eIn a well-insulated house, the share left to the backup stays modest; in a house that loses a lot of heat, it grows.

Two homes of the same size can have very different needs depending on wall and attic insulation, the age and orientation of the windows, the airtightness of the envelope and ceiling height. A seventies home that was never renovated may need more; a recent, well-sealed home may need less. We run a room-by-room on-site assessment before recommending a size, and that assessment decides.\u003c\/p\u003e\u003ch3\u003eWhy the right size heats and cools better\u003c\/h3\u003e\u003cp\u003eThe habit of going \"a little bigger, just to be sure\" hurts comfort with a central heat pump. An oversized unit reaches the setpoint too quickly, shuts off, then starts again. These short cycles wear out components, leave temperature gaps between the basement and the bedrooms and, in summer, stop the cooling before the coil has had time to remove the moisture. The house is cool, but clammy.\u003c\/p\u003e\u003cp\u003eOn the other hand, an undersized unit runs nonstop on heat-wave days and calls on the backup heat more often in winter. The right size runs long, steady cycles, moves air through the whole duct system and keeps temperatures even from one level to the next. The \u003cstrong\u003e3.5-ton\u003c\/strong\u003e size exists for homes that fall between two standard sizes, and it is often the one that delivers that steady operation.\u003c\/p\u003e\u003ch3\u003eTwo units working together\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eN4H5S42AKAAA\u003c\/strong\u003e outdoor unit houses the compressor, the outdoor coil and the fan that exchanges heat with the outside air. The \u003cstrong\u003eFJMA4X42L0CB\u003c\/strong\u003e indoor unit holds the indoor coil, the blower that pushes air into the \u003cstrong\u003educts\u003c\/strong\u003e and the filter location. The two are connected by an insulated copper refrigerant line set, control wiring and, on the indoor side, a condensate drain.\u003c\/p\u003e\u003cp\u003eThe system runs on \u003cstrong\u003eR-410A\u003c\/strong\u003e, a refrigerant that refrigeration technicians know well and for which parts and service tools are widely available. The pairing of the two units is not a detail: they are chosen to work together, and it is the ratings of the complete pairing that count, not those of a single unit.\u003c\/p\u003e\u003ch3\u003eHow a heat pump works\u003c\/h3\u003e\u003cp\u003eA heat pump does not create heat, it moves it. In winter, the refrigerant captures the heat contained in the outdoor air, even cold air; the compressor concentrates it and sends it to the indoor unit's coil, and the blower distributes it through the \u003cstrong\u003educts\u003c\/strong\u003e. In summer, a reversing valve flips the cycle: heat is captured inside the house and released outdoors.\u003c\/p\u003e\u003cp\u003eBecause it moves heat instead of producing it with electric resistance, a heat pump delivers more energy than it consumes for most of the year. That is what makes it the heart of a modern \u003cstrong\u003eheating and cooling\u003c\/strong\u003e system in a home that already has its ducts.\u003c\/p\u003e\u003ch3\u003eQuebec winters and backup heat\u003c\/h3\u003e\u003cp\u003eThis pairing is a conventional central heat pump; it is not listed as a cold-climate heat pump. Its heating capacity decreases as the outdoor temperature drops, as with any heat pump of this type. During periods of deep cold, the \u003cstrong\u003ebackup heat\u003c\/strong\u003e takes over: electric elements in the air handler, or the existing furnace in an installation that keeps it.\u003c\/p\u003e\u003cp\u003eThis is normal and planned from the outset. The thermostat runs the heat pump first and only calls on the backup when the house needs it. We size that backup according to the on-site assessment and list it in the quote, so the coldest January nights hold no surprises. During defrost cycles, the backup may also come on briefly to avoid blowing lukewarm air into the rooms.\u003c\/p\u003e\u003ch3\u003eCooling and humidity in summer\u003c\/h3\u003e\u003cp\u003eIn summer, the system cools the whole house through the same \u003cstrong\u003educts\u003c\/strong\u003e, from the upstairs bedrooms down to the finished basement. The indoor coil also removes moisture from the air: the condensed water drains away through the condensate drain. A properly sized system runs cycles long enough to dry the air well, which keeps the house comfortable at a reasonable setpoint.\u003c\/p\u003e\u003cp\u003eIn a two-level home, the upper floor tends to stay warmer. A balanced duct system, well-placed return air grilles and the right blower setting correct most of that gap.

It carries the indoor coil, where the refrigerant releases its heat in winter and captures it in summer. It houses the blower that pushes air through the \u003cstrong\u003educts\u003c\/strong\u003e to each room and draws it back through the return grilles. And it holds the filter, which protects both the coil and the home's air quality.\u003c\/p\u003e\u003cp\u003eThe \u003cstrong\u003eFJMA4X42L0CB\u003c\/strong\u003e unit is the \"air handler\" named in the product title. In most homes, we install it where the old furnace stood, in the basement or a mechanical room, and connect it to the existing supply plenum and air return. Fittings are adapted on site so the duct system stays airtight.\u003c\/p\u003e\u003ch3\u003eA home that keeps its ducts\u003c\/h3\u003e\u003cp\u003eThe main advantage of a central system is that it reuses a duct system that is already in place. No wall units in the rooms, no refrigerant lines running along the outside walls of each bedroom: warm or cool air comes out of the same registers as before. For a home where you want to keep the walls clear, it is often the most discreet option.\u003c\/p\u003e\u003cp\u003eThe duct system still has to be able to do its job. Undersized ducts, return air openings that are too small or crushed sections limit airflow, and a central heat pump is more sensitive to this than a furnace. We inspect the duct system before the quote and list any corrections needed. If the ducts have never been cleaned, replacing the unit is a good time to do it.\u003c\/p\u003e\u003ch3\u003eHomes suited to the 3.5-ton size\u003c\/h3\u003e\u003cp\u003eThis size typically suits a single-storey home with a large open area and a finished basement, a mid-sized cottage with three bedrooms upstairs, or an older home enlarged over the years whose furnace serves every room. These are typical examples, not rules.\u003c\/p\u003e\u003cp\u003eThe size is always confirmed by an on-site assessment. Attic insulation, the condition of the windows, the share of below-grade walls and sun exposure change the result from one home to the next. We do this assessment during the visit, room by room, and recommend another size if this one does not fit.\u003c\/p\u003e\u003ch3\u003eBackup heat for deep cold\u003c\/h3\u003e\u003cp\u003eThis pairing is a conventional central heat pump; it is not listed as a cold-climate heat pump. The lower the outdoor temperature, the lower its heating capacity. During deep cold, the \u003cstrong\u003ebackup heat\u003c\/strong\u003e takes over.\u003c\/p\u003e\u003cp\u003eIn an all-electric installation, the backup comes from heating elements housed in the air handler. They only come on when the heat pump can no longer hold the setpoint, and they briefly warm the air during defrost cycles. We choose the capacity of this backup according to the on-site assessment and the capacity of the electrical panel, and we list it in the quote.\u003c\/p\u003e\u003ch3\u003eA thermostat set up for a heat pump\u003c\/h3\u003e\u003cp\u003eA central heat pump is controlled a little differently from a furnace. The thermostat must be compatible with a heat pump and its backup: it runs the outdoor unit first, then only calls on the elements when the house really needs them. We configure it during commissioning.\u003c\/p\u003e\u003cp\u003eA practical tip: avoid large nighttime temperature setbacks in the middle of winter. In the morning, to recover several degrees at once, the thermostat calls on the backup longer than necessary. A steady setpoint, or a modest setback, lets the heat pump do most of the work.\u003c\/p\u003e\u003ch3\u003eThe outdoor unit in winter\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eHSH442GKA\u003c\/strong\u003e outdoor unit works outside all winter. When frost forms on its coil, it switches to defrost mode for a few minutes: a cloud of white vapour may then rise from it, which is normal. Meltwater must be able to drain freely under the unit, without forming ice that builds back up toward the coil.\u003c\/p\u003e\u003cp\u003eThat is why we install it on a stand, above the snow line, away from gutters and snow sliding off the roof. The location also takes into account bedroom windows, the neighbours and access for maintenance.\u003c\/p\u003e\u003ch3\u003eCooling through the same duct system\u003c\/h3\u003e\u003cp\u003eIn summer, the cycle reverses: the indoor unit's coil captures heat from the air in the house and the outdoor unit releases it outside. Cool air travels through the same \u003cstrong\u003educts\u003c\/strong\u003e as the heat in winter, up to the upstairs bedrooms and down to the basement.\u003c\/p\u003e\u003cp\u003eThe coil removes moisture from the air at the same time. Condensed water flows through the indoor unit's condensate drain to a discharge point, and the house becomes comfortable without having to lower the setpoint excessively. For homes whose upper floor stays warm in July, we check the balance of the duct system and the position of the returns.\u003c\/p\u003e\u003ch3\u003eSystem ratings\u003c\/h3\u003e\u003cp\u003eThe pairing of the \u003cstrong\u003eHSH442GKA\u003c\/strong\u003e outdoor unit and the \u003cstrong\u003eFJMA4X42L0CB\u003c\/strong\u003e indoor unit is not listed with SEER2 ratings in the AHRI certification directory.

A heat pump blows air that is less hot than an electric furnace, but in greater volume and for longer. The ducts, and especially the air returns, must let that airflow through.

It is the first point we check during the visit.\u003c\/p\u003e\u003cp\u003eWe assess the available capacity, the space for breakers and the cable route to the outdoor unit and to the air handler. The heat pump is fed by a \u003cstrong\u003ededicated circuit\u003c\/strong\u003e. If the panel or the service needs to be modified, we state it clearly in the written quote.\u003c\/p\u003e\u003ch3\u003eHomes suited to the 3.5-ton size\u003c\/h3\u003e\u003cp\u003eThis size typically suits a two-level cottage or house from the fifties or sixties with a basement, an enlarged bungalow or a good-sized semi-detached home. Many are heated by a forced-air electric furnace, and their insulation varies a great deal depending on the renovations done since they were built.\u003c\/p\u003e\u003cp\u003eThat is why the size is confirmed by a room-by-room on-site assessment. A recently insulated attic, new windows or a finished basement change the result. If the assessment shows that a 3-ton or 4-ton size is a better fit, we recommend it.\u003c\/p\u003e\u003ch3\u003eHow the heat pump heats the house\u003c\/h3\u003e\u003cp\u003eAn electric furnace produces heat with heating elements: it gives back as heat the electricity it uses, and no more. A heat pump moves it instead: the refrigerant captures the heat contained in the outdoor air, the compressor concentrates it, then the indoor unit's coil releases it into the air circulating through the \u003cstrong\u003educts\u003c\/strong\u003e.

Instead of short bursts of very hot air, air circulates longer at a moderate temperature. Most people find the house more even, with smaller gaps between the basement and the bedrooms. The blower can also run continuously, depending on the thermostat setting, to mix the air between levels and pass it through the filter.\u003c\/p\u003e\u003ch3\u003eIn deep cold, electric backup heat\u003c\/h3\u003e\u003cp\u003eThis pairing is a conventional central heat pump; it is not listed as a cold-climate heat pump. Its heating capacity drops with the outdoor temperature. When the cold becomes too intense, the air handler's backup elements take over and keep the house heated.\u003c\/p\u003e\u003cp\u003eThe thermostat manages this handoff: the heat pump first, the backup second, and only when needed. We size the backup according to the on-site assessment and the available electrical capacity.\u003c\/p\u003e\u003cp\u003eA useful clarification: the air handler's backup works like the elements of your current electric furnace. In deep cold, it therefore plays the role the furnace plays today; the rest of the winter, the heat pump does most of the work and the elements stay at rest.\u003c\/p\u003e\u003ch3\u003eSummer: cooling through the same ducts\u003c\/h3\u003e\u003cp\u003eMany homes heated by an electric furnace have never had central air conditioning, or make do with an old air conditioner at the end of its life. With this system, cool air travels in summer through the same \u003cstrong\u003educts\u003c\/strong\u003e as the heat in winter.

A heat pump does the same in summer, but it has a reversing valve that flips the cycle in winter: it then captures the heat contained in the outdoor air and delivers it indoors through the \u003cstrong\u003educts\u003c\/strong\u003e.

The outdoor unit now runs twelve months a year, under snow and freezing rain, and it must be installed accordingly. The indoor system must also be able to heat, with backup for deep cold. The following sections explain what this changes in your home.\u003c\/p\u003e\u003ch3\u003eThe outdoor location often has to change\u003c\/h3\u003e\u003cp\u003eA central air conditioner is often set on a slab at ground level, sometimes under an eave or near a walkway. That did not matter for a unit that sleeps all winter. A heat pump, however, must stay clear of snow to breathe, and it produces meltwater during its defrost cycles.\u003c\/p\u003e\u003cp\u003eWe therefore install the \u003cstrong\u003eHSH642GKA\u003c\/strong\u003e outdoor unit on a stand, above the snow line, away from snow and ice falling off the roof. We avoid placing it above a walkway or stairs, where defrost water could freeze.

With an old air conditioner, it may have been sized for another unit, used with another refrigerant or have insulation damaged by the sun. We inspect it and decide, case by case, whether it needs to be replaced.\u003c\/p\u003e\u003cp\u003eIn every case, the line set is insulated along its full length, evacuated and checked before the refrigerant is released. It is a step you no longer see once the job is done, but it matters for the life of the compressor.\u003c\/p\u003e\u003ch3\u003eA matched air handler\u003c\/h3\u003e\u003cp\u003eIn many original installations, the air conditioner's coil sits on top of the furnace, and the two units were bought at different times. Here, the \u003cstrong\u003eFJMA4X42L0CB\u003c\/strong\u003e indoor unit combines the coil, the blower and the filter in a single unit, chosen to work with the outdoor unit.

Its heating capacity decreases as the outdoor temperature drops. In deep cold, the air handler's backup heat, or the furnace kept in some installations, takes over.\u003c\/p\u003e\u003cp\u003eThe thermostat runs the heat pump first and only calls on the backup when necessary.

We install a compatible thermostat that controls the outdoor unit in heating and cooling, then the backup heat when the heat pump is no longer enough. Most of these thermostats also offer an emergency heat mode, which uses only the backup.\u003c\/p\u003e\u003cp\u003eThis emergency mode is only for when the outdoor unit is out of service, while you wait for our visit. Left on by mistake, it deprives the house of the heat pump's benefits.

If the upper floor stayed hot with the old air conditioner, the cause is often in the duct system: insufficient air returns, poorly balanced registers, an overly restrictive filter.

The \u003cstrong\u003eFJMA4X48L0CB\u003c\/strong\u003e indoor unit takes the place of the old furnace or air handler; it houses the indoor coil, the blower that feeds the whole duct system and the filter.\u003c\/p\u003e\u003cp\u003eBecause it moves heat instead of producing it, the heat pump delivers more energy than it consumes for most of the year. Air reaches the rooms through the existing registers, with no visible equipment. In winter, the outdoor unit periodically runs a defrost cycle of a few minutes; the vapour that rises from it then is normal.\u003c\/p\u003e\u003ch3\u003eHigh ceilings and open areas\u003c\/h3\u003e\u003cp\u003eLarge homes often have a living room with a cathedral ceiling, a mezzanine or a stairwell open over two levels. Warm air rises and collects there: in winter, the lower part of the room stays cool; in summer, the mezzanine becomes the warmest area of the house.\u003c\/p\u003e\u003cp\u003eA well-balanced duct system and the position of the air returns make a big difference. Running the blower continuously, depending on the thermostat setting, mixes the air between top and bottom and reduces those gaps. We look closely at these spaces during the visit, because they often decide how comfortable the whole house feels.\u003c\/p\u003e\u003ch3\u003eWinter: the heat pump first, the backup second\u003c\/h3\u003e\u003cp\u003eThis pairing is a conventional central heat pump; it is not listed as a cold-climate heat pump. Its heating capacity drops as the outdoor temperature falls. In deep cold, the air handler's \u003cstrong\u003ebackup heat\u003c\/strong\u003e, or the existing furnace in an installation that keeps it, takes over.\u003c\/p\u003e\u003cp\u003eIn a home of this size, the backup heat is sized carefully, together with the available electrical capacity. The thermostat always runs the heat pump first.\u003c\/p\u003e\u003ch3\u003eSummer in a large home\u003c\/h3\u003e\u003cp\u003eIn summer, cool air travels through the same \u003cstrong\u003educts\u003c\/strong\u003e as the heat, up to the upstairs bedrooms. The indoor coil removes moisture from the air and the water drains through the condensate drain. The right size, running long cycles, dries the house better than an oversized unit that keeps starting and stopping.\u003c\/p\u003e\u003cp\u003eIn a large home, the upper floor also picks up heat from the roof in the afternoon. Closed blinds on the west side, returns upstairs and a steady setpoint help far more than a very low setpoint set at the end of the day. The system keeps the house comfortable when it can work steadily, rather than catching up on accumulated heat.\u003c\/p\u003e\u003ch3\u003eLogisVert\u003c\/h3\u003e\u003cp\u003eThis pairing does not carry an amount on Hydro-Québec's \u003cstrong\u003eLogisVert\u003c\/strong\u003e list of October 19, 2026.

As it passes over the cold coil, the air in the house leaves its moisture behind, which condenses and drains through the condensate drain. The longer the cycles, the more water the system removes: one more reason to choose the right size rather than an oversized one.\u003c\/p\u003e\u003cp\u003eA simple tip for muggy days: leave the thermostat's fan on automatic rather than continuous. In continuous mode, air passing over the coil between cycles can bring back into the house some of the water still on it. A finished basement benefits in particular.\u003c\/p\u003e\u003ch3\u003eThe upstairs bedrooms\u003c\/h3\u003e\u003cp\u003eIn a two-level home, the bedrooms under the roof are the hardest to keep cool. Heat from the roof, warm air rising and registers that are often too small upstairs add up. The answer rarely lies in a bigger unit; it lies in the duct system: enough airflow upstairs, returns on the upper floor, dampers set correctly.\u003c\/p\u003e\u003cp\u003eWe examine these points during the visit and propose useful corrections in the quote.

West-facing glass weighs heavily on the summer load.\u003c\/p\u003e\u003cp\u003eThe room-by-room on-site assessment takes into account insulation, windows, shading and airtightness. We recommend the size it justifies, even if it is a different one.\u003c\/p\u003e\u003ch3\u003eWhy the pairing matters\u003c\/h3\u003e\u003cp\u003eThe ratings of a central system belong to a specific pairing, not to the outdoor unit alone. The \u003cstrong\u003eR4H5S48AKAAA\u003c\/strong\u003e outdoor unit houses the compressor, the outdoor coil and the fan; the \u003cstrong\u003eFJMA4X48L0CB\u003c\/strong\u003e indoor unit houses the indoor coil, the blower that feeds the duct system and the filter. It is this combination that was measured and certified.\u003c\/p\u003e\u003cp\u003eCombining the same outdoor unit with another coil, or keeping an old coil sitting on a furnace, would give other results, which no one has measured. That is why we install the pairing exactly as it appears on the certificate.\u003c\/p\u003e\u003ch3\u003eWinter, according to the certificate\u003c\/h3\u003e\u003cp\u003eOn the heating side, the HSPF2 of \u003cstrong\u003e7.5\u003c\/strong\u003e gives the seasonal efficiency. The certificate also lists \u003cstrong\u003e29,000 BTU\/h at -8 °C\u003c\/strong\u003e (17 °F) and \u003cstrong\u003e22,000 BTU\/h at -15 °C\u003c\/strong\u003e (5 °F), with a \u003cstrong\u003eCOP of 2.16\u003c\/strong\u003e at the -15 °C point.

In summer, a reversing valve flips the cycle: heat is captured inside the house and released outdoors, and the coil removes moisture from the air at the same time.\u003c\/p\u003e\u003cp\u003eThe indoor unit takes the place of the old furnace or air handler. It also holds the filter and receives the backup heat.

Its heating capacity decreases with the outdoor temperature. In deep cold, the air handler's \u003cstrong\u003ebackup heat\u003c\/strong\u003e, or the existing furnace in an installation that keeps it, takes over. The thermostat runs the heat pump first and only calls on the backup when necessary.\u003c\/p\u003e\u003cp\u003eIn a home that needs \u003cstrong\u003e4 tons\u003c\/strong\u003e, the backup heat represents a significant electrical load. We size it according to the on-site assessment, then check that it can run at the same time as the heat pump without exceeding the panel's capacity.

Before the quote, we check duct sizes and the air return, because a central heat pump only delivers its full efficiency if the airflow keeps up.

We avoid spots where snow builds up in drifts, the area under a roof without a gutter where snow and ice fall, and corners where the wind packs snow against the wall. We take into account the dryer vent, bedroom windows, the property line and access for maintenance.\u003c\/p\u003e\u003cp\u003eA unit of this size needs air: it must be able to draw in and discharge air freely, without being squeezed under a deck or behind a dense hedge.

Depending on the site, we set it on a ground stand, stable and level, or on a wall bracket fastened to the structure. A ground stand is often preferable near bedrooms, because it avoids transmitting vibrations to the wall. A wall bracket frees up the yard and is sometimes the only option when space is tight.\u003c\/p\u003e\u003ch3\u003eDefrost water and the condensate drain\u003c\/h3\u003e\u003cp\u003eIn winter, the outdoor unit defrosts periodically; white vapour rises from it and meltwater runs under the unit. This water must drain away freely, without forming ice that builds up toward the coil or an icy patch on a walkway. We take this into account when choosing the location and the height of the stand.\u003c\/p\u003e\u003cp\u003eIndoors, the air handler produces condensate in summer. The drain is connected to a compliant discharge point, with its slope checked; if there is no floor drain nearby, we plan a condensate pump.\u003c\/p\u003e\u003ch3\u003eLine set and electrical connection\u003c\/h3\u003e\u003cp\u003eThe copper line set connects the two units.

That is where a heat pump is most at ease. It captures heat from the outdoor air, the compressor concentrates it and the indoor unit distributes it through the \u003cstrong\u003educts\u003c\/strong\u003e: it moves heat instead of producing it.\u003c\/p\u003e\u003cp\u003eDuring these periods, the heat pump covers the home's needs on its own, delivering more energy than it consumes.

The two points are measured separately; we report each one as published.

Depending on its capacity and condition, that circuit can sometimes serve the new air handler's backup heat; we check this during the visit. The outdoor unit also needs its own \u003cstrong\u003ededicated circuit\u003c\/strong\u003e.\u003c\/p\u003e\u003cp\u003eWe therefore assess the panel's capacity for everything together: the heat pump, the backup heat and the rest of the house, on the coldest night of the year.

A large electric furnace does not automatically mean a five-ton heat pump is needed.\u003c\/p\u003e\u003cp\u003eThe room-by-room on-site assessment takes into account insulation, windows and airtightness. An oversized unit runs short cycles, dehumidifies poorly in summer and creates gaps between rooms.

The compressor concentrates it and the \u003cstrong\u003eR-410A\u003c\/strong\u003e refrigerant carries it to the indoor unit's coil, where the blower releases it into the air of the house. In summer, a reversing valve flips the cycle to provide cooling.\u003c\/p\u003e\u003cp\u003eWhen frost forms on the outdoor coil, the unit defrosts for a few minutes; a cloud of white vapour may then rise from it. This is normal, and the backup heat may come on briefly during that time to keep the supply air comfortable.\u003c\/p\u003e\u003ch3\u003eIn deep cold, the elements go back to work\u003c\/h3\u003e\u003cp\u003eThis pairing is a conventional central heat pump; it is not listed as a cold-climate heat pump.

This is normal. The heat pump heats the house with milder air that circulates for longer. The house warms more evenly, without bursts of very hot air followed by long pauses.\u003c\/p\u003e\u003cp\u003eIf the air feels cool to the touch, remember that it is still warmer than the room. A steady setpoint, without large nighttime setbacks, lets the heat pump do most of the work and avoids calling on the backup heat in the morning.\u003c\/p\u003e\u003ch3\u003eSummer, with cooling added\u003c\/h3\u003e\u003cp\u003eA home heated by an electric furnace does not always have central air conditioning. With this system, cool air travels in summer through the same \u003cstrong\u003educts\u003c\/strong\u003e, up to the upstairs bedrooms. The indoor coil also removes moisture from the air; the water drains through the condensate drain to a discharge point.\u003c\/p\u003e\u003cp\u003eDuct systems designed for an electric furnace sometimes have few registers upstairs, where summer heat builds up. We check this during the visit.
