The \u003cstrong\u003eWall-Mounted Heat Pump CONFORTO MHWAL | 9,000 BTU - R410A\u003c\/strong\u003e is a solid choice for this room: a size suited to a closed bedroom, and high cooling ratings, measured and published.\u003c\/p\u003e\n\u003cp\u003eIts certified ratings are \u003cstrong\u003e28.1 SEER2\u003c\/strong\u003e, \u003cstrong\u003e16.2 EER2\u003c\/strong\u003e and \u003cstrong\u003e11.5 HSPF2\u003c\/strong\u003e.

When the room has a lot of glass, faces west or has weak roof insulation, we check it with a load calculation: the heat coming through the roof can justify a larger size. We do not oversize on principle, because a unit that is too big cools quickly, stops and leaves the humidity in the room.\u003c\/p\u003e\n\u003ch3\u003eA 16.2 EER2 rating for heat-wave days\u003c\/h3\u003e\n\u003cp\u003eIn \u003cstrong\u003ecooling\u003c\/strong\u003e mode, the nominal capacity is \u003cstrong\u003e9,000 BTU\/h\u003c\/strong\u003e. The \u003cstrong\u003eEER2\u003c\/strong\u003e rating measures efficiency at the most demanding moment: a hot day, when the unit works hardest. At \u003cstrong\u003e16.2 EER2\u003c\/strong\u003e, this pairing stays efficient precisely during heat waves, when a bedroom under the roof needs it most.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003eSEER2\u003c\/strong\u003e rating describes efficiency over the whole summer, mild days included. At \u003cstrong\u003e28.1 SEER2\u003c\/strong\u003e, cooling this room takes little electricity for each hour of comfort, from June to September.\u003c\/p\u003e\n\u003ch3\u003eHumidity, the other half of summer comfort\u003c\/h3\u003e\n\u003cp\u003eA bedroom that is cool but humid is still unpleasant: the sheets stick, the air feels heavy. The heat pump's \u003cstrong\u003evariable-speed compressor\u003c\/strong\u003e addresses this by running long at low speed once the room reaches the set point. The indoor coil stays cold, moisture from the air condenses on it and drains away. This continuous \u003cstrong\u003edehumidification\u003c\/strong\u003e lets you sleep comfortably without setting the temperature too low.\u003c\/p\u003e\n\u003cp\u003eA few habits help too. Close the blinds on the sunny side during the day, and let the heat pump hold a steady set point rather than turning it off in the morning and restarting it at full power in the evening. A room under the roof that has heated up all day stores heat in its walls and ceiling; it is easier to keep it cool than to cool it all at once at bedtime.\u003c\/p\u003e\n\u003ch3\u003eWhere to place the head in a room under the eaves\u003c\/h3\u003e\n\u003cp\u003eUpstairs bedrooms often have low walls, sloped ceilings or dormers. The wall head must be installed on a wall high enough for the airflow to cover the room without aiming directly at the bed. We favour an interior wall or a gable wall, with enough clearance above the unit for air return. The louvres are then set upward in cooling, so the cool air settles naturally throughout the room.\u003c\/p\u003e\n\u003ch3\u003eWinter, certified figures\u003c\/h3\u003e\n\u003cp\u003eThe same bedroom is often cold in winter.

The two points are measured separately; we report each one as published.\u003c\/p\u003e\n\u003cp\u003eIn practice, at these temperatures the heat pump delivers at least as much heat as its nominal capacity, which makes it a true primary heat source for a well-insulated bedroom for most of the winter. The existing baseboard can stay in place as backup, set a few degrees below the set point. The ENERGY STAR \u003cstrong\u003ecold-climate designation\u003c\/strong\u003e confirms that the pairing was evaluated for cold winters.\u003c\/p\u003e\n\u003ch3\u003eThe technology: inverter and R-410A\u003c\/h3\u003e\n\u003cp\u003eA \u003cstrong\u003ewall-mounted heat pump\u003c\/strong\u003e moves heat: in winter, it draws it from the outdoor air and delivers it to the bedroom; in summer, it does the reverse. \u003cstrong\u003eInverter\u003c\/strong\u003e technology lets the compressor change speed instead of running all-or-nothing, which stabilizes the temperature and reduces consumption.

Instead, we mount it at a height that lets the airflow reach the floor in heating and sweep the volume in cooling, often on a solid wall under the mezzanine or facing the large window. The chosen height must also allow easy access to the filters.

In a recent, well-insulated 4 ½ apartment, it can also temper a bedroom and the hallway that serves it. In an older house, with original windows or a poorly insulated attic, the same capacity covers a smaller area.\u003c\/p\u003e\u003cp\u003eThat is why we never pick a size by eye. The \u003cstrong\u003eload calculation\u003c\/strong\u003e done during the visit takes into account the room's orientation, the glass area, the insulation of the walls and ceiling, the floor level and how the room is used.

Every restart wastes energy, the temperature swings, and in summer the air stays clammy because the coil does not have time to remove the moisture. A correctly sized cassette does the opposite: it runs for long periods at low speed.\u003c\/p\u003e\u003cp\u003eThe \u003cstrong\u003evariable-speed compressor\u003c\/strong\u003e adjusts its speed to the room's actual demand instead of running all-or-nothing. When the room reaches the right temperature, it slows down and holds the balance. In a bedroom, this slow, steady operation gives stable comfort all night, without a burst of air each time the unit restarts.\u003c\/p\u003e\u003ch3\u003eAir that comes down from the ceiling, spread on four sides\u003c\/h3\u003e\u003cp\u003eA wall-mounted heat pump blows from one side of the room, and the air has to cross the space to reach the opposite wall. The cassette sits toward the centre of the ceiling and spreads the air in four directions through the louvres around its grille. The air fans out toward the walls, then comes back down, which shortens the distance to the corners and evens out the temperature.\u003c\/p\u003e\u003cp\u003eWe choose the exact location so that the airflow does not fall directly on the bed, the reading chair or the workstation. In heating, warm air tends to stay near the ceiling: the central position of the cassette and a good louvre setting help that air come back down to the floor. In cooling, the cool air, being heavier, comes down on its own and spreads easily.\u003c\/p\u003e\u003ch3\u003eWhat the ceiling needs to offer\u003c\/h3\u003e\u003cp\u003eA cassette is installed between the joists or above a suspended ceiling, in a space deep enough to hold the unit and accessible for maintenance. During the visit, we check what the ceiling hides: joist direction, ventilation ducts, plumbing, wiring, recessed lights. We also trace the route of the refrigerant lines and the drain to the outside wall.\u003c\/p\u003e\u003cp\u003eA suspended tile ceiling, common in basements and offices, makes the work much simpler. In a drywall ceiling, we cut a clean opening to the cassette's size, and the grille covers it. Under a concrete slab with no suspended ceiling, a cassette is not an option: we then propose another type of unit.\u003c\/p\u003e\u003ch3\u003eHow the system works\u003c\/h3\u003e\u003cp\u003eA heat pump does not make its heat with a resistance element: it moves heat. In winter, the \u003cstrong\u003erefrigerant\u003c\/strong\u003e captures the heat contained in the outdoor air, even cold air, the compressor concentrates it, and the cassette releases it into the room. In summer, the cycle reverses and the room's heat is rejected outdoors. The refrigerant lines connect the two units and carry nothing but refrigerant.\u003c\/p\u003e\u003cp\u003eThis system uses \u003cstrong\u003eR-410A\u003c\/strong\u003e, the refrigerant found in a large share of the heat pumps installed in recent years. Technicians know it well and servicing it is routine. New equipment is gradually moving to next-generation refrigerants; an R-410A system that is properly installed, properly charged and serviced every year remains a reliable choice.\u003c\/p\u003e\u003ch3\u003eQuebec winters, according to the certificate\u003c\/h3\u003e\u003cp\u003eThe certificate lists \u003cstrong\u003e9,000 BTU\/h at -8 °C\u003c\/strong\u003e (17 °F), with a \u003cstrong\u003eCOP of 1.91\u003c\/strong\u003e. At this temperature, common in the heart of winter, the cassette still delivers 100 % of its nominal capacity. The certificate also lists \u003cstrong\u003e10,000 BTU\/h at -15 °C\u003c\/strong\u003e (5 °F), with a \u003cstrong\u003eCOP of 1.80\u003c\/strong\u003e.\u003c\/p\u003e\u003cp\u003eSeeing a higher value at the colder point can be surprising. The two points are measured separately, under distinct test conditions; we report each one as published, without joining them into a curve.\u003c\/p\u003e\u003cp\u003eLower still, the certificate publishes \u003cstrong\u003e4,400 BTU\/h at -30 °C\u003c\/strong\u003e, with a \u003cstrong\u003eCOP of 1.02\u003c\/strong\u003e, or 49 % of the nominal capacity. On the coldest nights of the year, the cassette keeps heating, but at reduced capacity. We recommend keeping the existing electric baseboards as backup: they stay idle most of the winter and take over only when the cold requires it.\u003c\/p\u003e\u003ch3\u003eSummer: cooler and drier air\u003c\/h3\u003e\u003cp\u003eIn cooling, the cassette cools the room and at the same time removes moisture from the air, which condenses on the coil and flows out through the drain. In a bedroom under the roof or a west-facing office, it is often the heavy, humid air that keeps you from sleeping or working, more than the temperature itself. A correctly sized unit that runs for long periods at low speed dries the air better than an oversized one.\u003c\/p\u003e\u003cp\u003eThe \u003cstrong\u003e13.0 EER2\u003c\/strong\u003e rating measures precisely the efficiency during the hot hours, when the unit works at full load.

Its walls are short, often pierced by small high windows, and they already hold the TV, the shelves or the desk.

The ceiling, on the other hand, is free.\u003c\/p\u003e\u003cp\u003eIn a finished basement, it is very often suspended.

In a long room, typical of basements, we place it so as to reach both ends; in an open area, between the living zones rather than above the sofa. In heating, warm air tends to stay high, hence the importance of the central position and the louvre setting to bring it back toward the floor. In cooling, the cool air comes down on its own.\u003c\/p\u003e\u003ch3\u003eThe technology: variable speed and R-410A\u003c\/h3\u003e\u003cp\u003eA \u003cstrong\u003eheat pump\u003c\/strong\u003e moves heat instead of producing it with a resistance element.

The distances are shorter, the air mixes better and the temperature is more even from one end to the other.

We place the cassette between the living zones, away from the range and the hood, and never directly above a workstation, a table or a sofa. We take into account the light fixtures, the joists and the obstacles hidden in the ceiling.\u003c\/p\u003e\u003cp\u003eThe shape of the room also matters. In an L-shaped space, a single cassette does not always reach the end of the wing, and we say so during the visit rather than promise what the unit cannot do. In heating, warm air tends to stay high: the cassette's position and the louvre setting serve to bring it back toward the floor.\u003c\/p\u003e\u003ch3\u003eElectrical capacity, checked before the quote\u003c\/h3\u003e\u003cp\u003eA unit of this size needs a \u003cstrong\u003ededicated circuit\u003c\/strong\u003e. In a house whose panel is already heavily loaded by the range, the dryer, the water heater and the baseboards, you have to make sure there is room left. We check the panel capacity during the visit.

Many heat pumps lose half their capacity, or more, at -30 °C. This one keeps more than four-fifths of it according to its certificate, and it still produces one and a half times as much heat as it uses in electricity. The -15 °C point, higher than the -8 °C one, comes from a separate test: we do not join the two into a curve.\u003c\/p\u003e\u003cp\u003eThis does not remove the need for backup heating: in a large space, we always recommend keeping the baseboards or the existing system for extreme nights and maintenance periods.

In a well-insulated building, it can heat and cool most of an open floor; in an older, heavily glazed building, it covers a smaller area.\u003c\/p\u003e\u003ch3\u003eOne large unit or two smaller ones\u003c\/h3\u003e\u003cp\u003eA cassette heats and cools the space it is in. If the area to cover is divided into several closed rooms, two smaller units often give a better result than one large cassette. Conversely, in a truly open space, a single well-placed unit is simpler: one outdoor unit, one wall opening, one maintenance visit.\u003c\/p\u003e\u003cp\u003eThe choice is made with the \u003cstrong\u003eload calculation\u003c\/strong\u003e. A unit too large for the room would idle most of the year and short-cycle in spring and fall; a unit too small would strain in January.

In a house or a commercial space whose panel is already heavily used, we check during the visit that the necessary room remains. If a panel adjustment is required, it appears clearly in the written quote. In a commercial space, we also coordinate the connection location with the building manager when needed.\u003c\/p\u003e\u003ch3\u003eDistributing air in a large volume\u003c\/h3\u003e\u003cp\u003eThe cassette spreads the air in four directions through the louvres around its grille. In a large space, this distribution reduces the temperature differences between the centre and the walls, where a wall-mounted heat pump would leave the opposite end under-heated. We place it between the areas of use, away from fixed workstations, and clear of a range or a hood.\u003c\/p\u003e\u003cp\u003eIn heating, warm air tends to collect under the ceiling, especially in a tall volume. The cassette's central position and the louvre setting help bring that air back toward the floor; in a loft, a ceiling fan set to low speed usefully completes the mixing.\u003c\/p\u003e\u003ch3\u003eCooling an occupied space\u003c\/h3\u003e\u003cp\u003eA commercial space or a large reception room often hosts several people at once, and each one adds heat and moisture.

The load calculation confirms the choice during the visit.\u003c\/p\u003e\n\u003cp\u003eWe are often asked whether a single head, mounted in the hallway between the two rooms, would do the job. With the door open, a little air circulates; with the door closed to sleep or work, almost nothing gets through. One head per room is the only way to guarantee each its own temperature, and that is exactly what a two-zone condenser allows.\u003c\/p\u003e\n\u003ch3\u003eTwo MHWAL09DACFC heads, two set points\u003c\/h3\u003e\n\u003cp\u003eBoth rooms get the same head, the \u003cstrong\u003eMHWAL09DACFC\u003c\/strong\u003e, each with its own remote and set point.

With 2 zones out of a maximum of 2, every connection is used. If a third room needs to be equipped one day, another unit will be required; we tell you before signing, so the choice is made with full knowledge.\u003c\/p\u003e\n\u003ch3\u003eSleep, the first argument\u003c\/h3\u003e\n\u003cp\u003eIn a bedroom, it is the night that judges a system. The \u003cstrong\u003einverter compressor\u003c\/strong\u003e slows down as soon as the set point is reached and holds the temperature without abrupt starts. In summer, extended low-speed operation removes moisture from the air, which lets you sleep cool without setting the set point too low. For cooling, the system is built around a nominal size of \u003cstrong\u003e18,000 BTU\/h\u003c\/strong\u003e shared between the two rooms.\u003c\/p\u003e\n\u003cp\u003eCompared with a window air conditioner, the difference is clear: the condenser and its compressor are outside, the window stays free and locks, and only a flow of air remains in the room.

The two points are measured separately; we report each one as published.\u003c\/p\u003e\n\u003cp\u003eThe figure at -15 °C exceeds the 18,000 BTU nominal size. This is not an error: in cold weather, the inverter compressor can run faster than its reference speed to offset the home's heat losses. A COP of 1.90 means that at that temperature, each kilowatt-hour consumed returns 1.90 kilowatt-hours of heat, where a baseboard returns one. ENERGY STAR's \u003cstrong\u003ecold-climate designation\u003c\/strong\u003e confirms that the combination meets the low-temperature performance criteria.\u003c\/p\u003e\n\u003cp\u003eThese figures come from certificate \u003cstrong\u003eAHRI 210605810\u003c\/strong\u003e, published by NEEP.\u003c\/p\u003e\n\u003ch3\u003eBackup heat and defrost\u003c\/h3\u003e\n\u003cp\u003eThe certificate does not publish a point colder than -15 °C.

Grandparents often prefer a warmer house and spend their days at home; the family on the ground floor leaves in the morning and comes back in the evening. A single set point for the whole house is bound to leave someone unhappy. With two zones, each household sets its own unit as it sees fit, without negotiating over a thermostat.\u003c\/p\u003e\n\u003cp\u003eThis size also suits any house that divides into two large, well-separated spaces: an open ground floor and a finished basement, a house and its addition, or a large single-storey house whose bedroom wing is closed off.

The second unit gets the head that matches its load: another MHWAL24DACFC if it is just as large, the \u003cstrong\u003eMHWAL12DACFC\u003c\/strong\u003e if it is a more compact studio. The \u003cstrong\u003eMHWAL09DACFC\u003c\/strong\u003e is better suited to small closed rooms.\u003c\/p\u003e\n\u003cp\u003eThe two heads share the condenser's capacity. When both units call at full demand, it is split between them; when only one is occupied, it gets all the available capacity. With 2 zones out of a maximum of 5, three connections remain free to equip closed bedrooms later, after checking the remaining capacity.\u003c\/p\u003e\n\u003ch3\u003eA single mode for both units\u003c\/h3\u003e\n\u003cp\u003eThere is one thing to know before choosing this system: the heads on the same condenser always work in the same mode, all heating or all cooling. Each household sets its own temperature, but not the mode. In practice, both units live through the same season and the question rarely comes up; it can, however, arise on a few spring or fall days. We discuss it during the visit to agree with you on how to handle those days.\u003c\/p\u003e\n\u003cp\u003eThe solution is usually simple. On a mild day when one unit needs a little heat and the other does not, the second unit's head can be turned off or switched to fan mode while the first keeps heating. Each unit keeps its own remote, which prevents one household from unintentionally changing the other's setting.\u003c\/p\u003e\n\u003ch3\u003eWhat the certificate shows for winter\u003c\/h3\u003e\n\u003cp\u003eThe certificate lists \u003cstrong\u003e36,000 BTU\/h at -8 °C\u003c\/strong\u003e (17 °F), with a \u003cstrong\u003eCOP of 2.30\u003c\/strong\u003e, and \u003cstrong\u003e45,000 BTU\/h at -15 °C\u003c\/strong\u003e (5 °F), with a \u003cstrong\u003eCOP of 2.00\u003c\/strong\u003e. The maximum published capacity is \u003cstrong\u003e45,000 BTU\/h at -15 °C\u003c\/strong\u003e. The two points are measured separately; we report each one as published.\u003c\/p\u003e\n\u003cp\u003eThe -15 °C point corresponds to 94% of the 48,000 BTU nominal size. At that temperature, a COP of 2.00 means that each kilowatt-hour consumed returns two kilowatt-hours of heat, where an electric baseboard returns one. ENERGY STAR's \u003cstrong\u003ecold-climate designation\u003c\/strong\u003e confirms that the combination meets the low-temperature performance criteria.\u003c\/p\u003e\n\u003cp\u003eThese figures come from certificate \u003cstrong\u003eAHRI 210605819\u003c\/strong\u003e, published by NEEP.\u003c\/p\u003e\n\u003ch3\u003eBackup heat during deep cold\u003c\/h3\u003e\n\u003cp\u003eThe certificate does not publish a point colder than -15 °C. In a unit occupied by older people, we are particularly keen on keeping the backup in place: the existing \u003cstrong\u003eelectric baseboards\u003c\/strong\u003e, set slightly below the heads' set point, stay off most of the time and take over during extreme cold. They also fill in the \u003cstrong\u003edefrost cycles\u003c\/strong\u003e, those few minutes when the condenser melts the frost off its coil and the heads stop blowing warm air.

Warm air collects under the ceiling, cool air stays at floor level, and your feet can be cold in a room that seems warm on the thermometer.

A small wall head is not enough to stir such a volume.\u003c\/p\u003e\n\u003cp\u003eThis size therefore targets homes whose main room is large and tall: a bungalow with a cathedral ceiling, a country house with a mezzanine, a living room extended under a sloped roof.

Two homes of the same size can have very different needs depending on wall and attic insulation, window age, orientation and how airtight the envelope is. An unrenovated home from the sixties may need the next size up; a recent, well-sealed home often does fine with this one. A room-by-room load calculation settles it, and we do it before proposing a size.\u003c\/p\u003e\u003ch3\u003eWhy the right size heats and cools better\u003c\/h3\u003e\u003cp\u003eFor years, air conditioners were chosen \"a little bigger, to be safe.\" With a heat pump, that habit costs comfort. An oversized unit reaches the set point too quickly, stops, then starts again: these short cycles wear out components, leave temperature differences between rooms and, in summer, shut off the cooling before the coil has had time to remove moisture. The house is cool, but clammy.\u003c\/p\u003e\u003cp\u003eA properly sized system runs for long periods at low speed. Air moves continuously through the \u003cstrong\u003educts\u003c\/strong\u003e, the upstairs bedrooms get their share and moisture is removed over the hours. In a small home, the \u003cstrong\u003e1.5-ton\u003c\/strong\u003e size is often the one that allows this calm, steady operation, summer and winter.\u003c\/p\u003e\u003ch3\u003eHow the variable-speed heat pump works\u003c\/h3\u003e\u003cp\u003eA heat pump does not make heat, it moves it. In winter, the refrigerant captures heat from the outdoor air, even very cold air; the compressor concentrates it and sends it to the indoor unit's coil, and the blower distributes it through the ducts. In summer, a reversing valve flips the cycle: heat from the house is released outdoors.\u003c\/p\u003e\u003cp\u003eThe compressor is \u003cstrong\u003evariable-speed\u003c\/strong\u003e (\u003cstrong\u003einverter\u003c\/strong\u003e technology). Instead of running flat out or not at all, it adjusts its speed to the actual demand: it slows down in mild weather and speeds up as the cold sets in. The system runs on \u003cstrong\u003eR-410A\u003c\/strong\u003e, a refrigerant that refrigeration technicians know well.\u003c\/p\u003e\u003ch3\u003eQuebec winters, according to the certificate\u003c\/h3\u003e\u003cp\u003eThe certificate lists \u003cstrong\u003e13,500 BTU\/h at -8 °C\u003c\/strong\u003e (17 °F) with a \u003cstrong\u003eCOP of 2.60\u003c\/strong\u003e, and \u003cstrong\u003e16,500 BTU\/h at -15 °C\u003c\/strong\u003e (5 °F) with a \u003cstrong\u003eCOP of 2.04\u003c\/strong\u003e. The two points are measured separately; we report each one as published, without extrapolating. At -15 °C, the listed capacity is about 92% of the 18,000 BTU\/h nominal size.\u003c\/p\u003e\u003cp\u003eThe certificate goes further: at \u003cstrong\u003e-30 °C\u003c\/strong\u003e, it still lists \u003cstrong\u003e10,500 BTU\/h\u003c\/strong\u003e with a \u003cstrong\u003eCOP of 1.53\u003c\/strong\u003e.

All three ratings are measured under standardized protocols, which makes it possible to compare systems from different brands on the same basis.\u003c\/p\u003e\u003ch3\u003eThe MHAH124DACFC indoor unit\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eMHAH124DACFC\u003c\/strong\u003e air handler contains the indoor coil and the blower that pushes air through the duct system. It is installed where the furnace stood, usually in the basement, and connects to the existing supply plenum and air return. Its condensate drain is routed to a floor drain or a pump.\u003c\/p\u003e\u003cp\u003eDuring deep cold, backup heat usually comes from electric heating elements housed in the indoor unit. The difference from the old furnace is that these elements now only serve as a supplement, when the heat pump is no longer enough. We size them from the load calculation and set the thermostat so they only come on when needed.\u003c\/p\u003e\u003ch3\u003eCentral air conditioning as a bonus\u003c\/h3\u003e\u003cp\u003eA home that only had a furnace gains central air conditioning at the same time. In summer, the system cools every room served by the ducts, bedrooms included, with no window units. The compressor slows down once the set point is reached, which keeps the air cool without short cycles and removes moisture over the hours, a real advantage on heavy July days.\u003c\/p\u003e\u003cp\u003eOn an open-plan main floor, cool air spreads easily; in closed bedrooms, the air return makes the difference.

During the visit, we examine the main ducts and branches, the condition of the joints, the number and location of the registers, the air return and the filter location.

Taking the smaller size would make the backup heat work more often in winter; taking the larger size would cause short cycles in spring, in fall and for much of the summer. The in-between size, when it matches the calculation, is the one that runs longest within its efficiency range.\u003c\/p\u003e\u003cp\u003eIt often suits a two-storey cottage, a large bungalow with a finished basement or a split-level on the \u003cstrong\u003eNorth Shore\u003c\/strong\u003e or in \u003cstrong\u003eLongueuil\u003c\/strong\u003e. These examples are only indicative: wall and roof insulation, window age, orientation and airtightness change the result.

The load calculation takes this into account.\u003c\/p\u003e\u003cp\u003eRegister placement matters too. Registers under the windows counter the cold air that drops from the glass in winter; a well-placed return draws air from the whole room back to the indoor unit.

At -30 °C, the heat pump still delivers slightly more heat than the electricity it uses, but the gap with ordinary electric heating becomes thin.

Backup that kicks in too early erases part of the gains; backup that is too weak leaves the house cool in deep cold.

A central heat pump moves heat instead of producing it. That heat comes from the outdoor air: the \u003cstrong\u003eR-410A\u003c\/strong\u003e refrigerant captures it outside, the compressor concentrates it and the air handler distributes it through the ducts.

The air coming out of the registers is less hot than what the electric furnace's elements used to push, but it circulates longer, which gives a steadier temperature from room to room. It is a change of habit; most occupants quickly find it more comfortable.\u003c\/p\u003e\u003ch3\u003eElectrical: backup heat and service capacity\u003c\/h3\u003e\u003cp\u003eIn a home heated by an electric furnace, the panel already feeds large heating elements. The central heat pump redistributes that load: the outdoor unit needs its own circuit, and the backup heating elements housed in the indoor unit take over from the furnace during deep cold. Together, they have to fit in the panel and on the electrical service, on top of the home's other appliances.\u003c\/p\u003e\u003cp\u003eDuring the visit, we check the capacity of the electrical service and the space available in the panel. If an upgrade is needed, we state it in the written quote, before signing. We also size the backup heat from the load calculation: enough to keep the house comfortable in deep cold, without overloading the installation.\u003c\/p\u003e\u003ch3\u003eCentral heat pump or ADD-ON\u003c\/h3\u003e\u003cp\u003eThere are two ways to add a heat pump to a home heated by an electric furnace. The first, the one on this page, removes the furnace and hands all the heating to the heat pump and the backup elements of its air handler. The second, the ADD-ON approach, keeps the existing electric furnace, if it is in good condition, and adds a heat pump coil on its air outlet; its elements then serve as backup in deep cold.\u003c\/p\u003e\u003cp\u003eThe right choice depends on the furnace's age and condition, its blower, the space available in the mechanical room and your preferences. A furnace at the end of its life, with a noisy blower or tired elements, points toward the central heat pump; a recent furnace in good condition points toward ADD-ON.

The right size, however, is determined on site, not from a rule of thumb: we look at insulation, windows and the condition of the ductwork before recommending an output. If the house needs more, the same series comes in larger sizes, and we will tell you so plainly.\u003c\/p\u003e\n\u003cp\u003eOn the electrical side, Conforto lists a total amperage of 44 A at 240 V, single phase. Breaker and wire sizes are confirmed from the manual for this code and the rating plate; we validate them before touching the panel. The cabinet measures 20 in wide by 21 in deep and weighs 105 lb (48 kg) shipped, which is manageable on a basement staircase.\u003c\/p\u003e\n\u003cp\u003eThe furnace can also take central air conditioning with a maximum capacity of 3 tons.

The Conforto AT1243 answers that gap with four 3,000 W elements, turned on one by one in four stages. In mild weather, a single element can be enough; as the cold sets in, the boiler adds a second, then a third, up to the full 12 kW at 240 V, or 41,000 BTU\/h according to the manufacturer.\u003c\/p\u003e\n\u003cp\u003eThe controller also rotates the elements: it is not always the same one that starts first. An immersion sensor at the heat exchanger outlet controls the stages and prevents short cycling.\u003c\/p\u003e\n\u003cp\u003eIn the AT series, the AT1243 sits next to the AT1226, with the same output but fewer, larger elements.

In both cases, the AT1243 mounts on the wall, weighs about 70 lb (32 kg) as shipped and connects to the loop with 1 1\/4 in NPT fittings. The loop must supply at least 4.1 gpm for a 20 °F ΔT.\u003c\/p\u003e\n\u003cp\u003eElectrically, Conforto requires a dedicated 240 V single-phase circuit, with a minimum ampacity of 70.0 A and maximum protection of 70 A.

The Conforto KLE-02-G027-05 was designed for that role. At 27 kW, or 92,190 BTU\/h according to Conforto, it is the strongest Lowboy in the series, still in a 34 1\/2 in high cabinet that blows air out through the top.\u003c\/p\u003e\n\u003cp\u003eIt is mainly for homeowners replacing a low-profile furnace in a basement where a tall furnace would not fit, and whose home has high heating needs.\u003c\/p\u003e\n\u003ch3\u003eA blower sized for the house\u003c\/h3\u003e\n\u003cp\u003eWhat changes compared with the smaller sizes is the blower: a 12 x 10 in wheel driven by a four-speed 3\/4 HP PSC motor. On HIGH, Conforto publishes 1,775 CFM at 0.2 in. w.c. and 1,600 CFM at 0.5 in. w.c. That airflow allows a central air conditioner or heat pump coil up to 5.0 tons, on the supply or the return side.\u003c\/p\u003e\n\u003cp\u003eHeating, for its part, happens in stages. The six elements, three of 5 kW and three of 4 kW, do not all start at once: a 15 kW first stage covers most days, and the rest is added during cold snaps. ComfortMax modulates the elements every cycle and QuietComfort pre-warms recirculated air at low energy.\u003c\/p\u003e\n\u003ch3\u003eHow it fits your home\u003c\/h3\u003e\n\u003cp\u003eA furnace this size needs planning. Conforto requires a 240 V single-phase circuit with a 150 A minimum ampacity, a breaker of no more than 150 A and 1 AWG wire. In many homes, that is a large share of the electrical service capacity: it must be checked before choosing this size.
