The \u003cstrong\u003e3-Zone Heat Pump ARCOAIRE D5CMHA | 30,000 BTU - R454B\u003c\/strong\u003e gives each one a head and a set point, from a single condenser.

The heads are chosen from the \u003cstrong\u003eD5FSHAH06XAK\u003c\/strong\u003e, \u003cstrong\u003eD5FSHAH09XAK\u003c\/strong\u003e, \u003cstrong\u003eD5FSHAH12XAK\u003c\/strong\u003e and \u003cstrong\u003eD5FSHAH18XAK\u003c\/strong\u003e \u003cstrong\u003ewall-mounted heat pump\u003c\/strong\u003e models.\u003c\/p\u003e\u003cp\u003eThe system is rated \u003cstrong\u003e24.0 SEER2\u003c\/strong\u003e, \u003cstrong\u003e13.2 EER2\u003c\/strong\u003e and \u003cstrong\u003e10.7 HSPF2\u003c\/strong\u003e.

The certificate still lists its capacity at \u003cstrong\u003e-30 °C\u003c\/strong\u003e, and the system qualifies for a \u003cstrong\u003e$4,200 LogisVert grant\u003c\/strong\u003e.\u003c\/p\u003e\u003ch3\u003eThe typical single-storey: a living room and two bedrooms\u003c\/h3\u003e\u003cp\u003eThe layout is familiar in the bungalow neighbourhoods of \u003cstrong\u003eLaval\u003c\/strong\u003e, \u003cstrong\u003eLongueuil\u003c\/strong\u003e or the \u003cstrong\u003eNorth Shore\u003c\/strong\u003e: living room, dining room and kitchen at the front, two bedrooms along a hallway at the back. A single head in the living room heats the open area well, but the heat does not turn the corner of the hallway and does not enter a bedroom whose door stays closed at night. With three zones, the living room keeps its daytime temperature, and each bedroom its own for sleeping.\u003c\/p\u003e\u003cp\u003eThe same logic applies to a two-storey semi-detached house whose ground floor forms one zone and the two upstairs bedrooms two more. In every case, the size of the rooms, the age of the windows and the attic insulation weigh on the real load; we measure them before confirming the size.\u003c\/p\u003e\u003ch3\u003eReplacing baseboards, room by room\u003c\/h3\u003e\u003cp\u003eWith \u003cstrong\u003eelectric baseboards\u003c\/strong\u003e, each room already has its own thermostat; that is precisely what multi-zone keeps. Each head has its own remote, schedules and set point, and the heat pump takes on most of the season's heating. The baseboards stay in place: they serve as backup in deep cold and in rooms that are not served, such as a bathroom or an entrance. The difference is felt mostly in the distribution: the head circulates the air of the room, while a baseboard mostly heats the area in front of the window.\u003c\/p\u003e\u003cp\u003eA practical tip: with a heat pump, large set-point swings between day and night are less useful than with baseboards. A steady temperature, slightly lowered at night, lets the compressor work at low speed, where it is most efficient.\u003c\/p\u003e\u003ch3\u003eChoosing three heads from four sizes\u003c\/h3\u003e\u003cp\u003eEach head's code indicates its size, from the D5FSHAH06XAK, the most compact, to the D5FSHAH18XAK, the largest. In a bungalow, the open area usually gets the largest size, the primary bedroom an intermediate size, and a small bedroom or office the most compact head. The total of the three heads must stay within the combinations the manufacturer allows for this condenser; we check this in the \u003cstrong\u003eload calculation\u003c\/strong\u003e, taking into account the moment when all three zones call at the same time.\u003c\/p\u003e\u003ch3\u003eWhat a single condenser gains you\u003c\/h3\u003e\u003cp\u003eThree independent wall-mounted heat pumps would mean three units outside, three stands to clear of snow and three circuits at the electrical panel. Here, a single condenser, placed in the most discreet spot on the lot, serves all three rooms on one \u003cstrong\u003ededicated circuit\u003c\/strong\u003e. The facade stays cleaner, and outdoor maintenance is done in one go. The trade-off to know: the three heads work in the same mode at any given time, heating or cooling, each at its own temperature.\u003c\/p\u003e\u003ch3\u003eA fourth zone, if the house changes\u003c\/h3\u003e\u003cp\u003eThe D5CMHAH30EAK accepts a fourth head. If the basement is later finished as a family room or guest room, it can be connected to the same condenser, provided the combination of four heads remains allowed. Mention this project during the visit: it can influence the size of the first three heads and the condenser location.\u003c\/p\u003e\u003ch3\u003eWinter performance: the certificate's figures\u003c\/h3\u003e\u003cp\u003eThe certificate lists \u003cstrong\u003e35,000 BTU\/h at -8 °C\u003c\/strong\u003e and \u003cstrong\u003e36,000 BTU\/h at -15 °C\u003c\/strong\u003e. The two points are measured separately; we report each one as published. In both cases, the published value exceeds the nominal 30,000 BTU size, which leaves a useful margin when all three zones call on a January morning.\u003c\/p\u003e\u003cul\u003e\u003cli\u003eCOP of 2.40 at the -8 °C point\u003c\/li\u003e\u003cli\u003eCOP of 2.00 at the -15 °C point\u003c\/li\u003e\u003cli\u003eMaximum capacity at -30 °C: 22,400 BTU\/h, COP of 1.47\u003c\/li\u003e\u003cli\u003eHeating certified down to -30 °C\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eThese figures come from certificate \u003cstrong\u003eAHRI 215357141\u003c\/strong\u003e, published by NEEP. The closer the temperature gets to -30 °C, the lower the published capacity: the baseboards you keep then take over.\u003c\/p\u003e\u003ch3\u003eCooling and dehumidification\u003c\/h3\u003e\u003cp\u003eIn a bungalow, the roof heats the rooms directly below, and west-facing bedrooms stay warm late into the evening. The \u003cstrong\u003einverter compressor\u003c\/strong\u003e responds by speeding up when all three zones call for cooling, then slows down as soon as the set points are reached. Those long low-speed cycles are also the ones that remove the most moisture from the air, and each head's \u003cstrong\u003edehumidification\u003c\/strong\u003e mode handles muggy days without overcooling. The new-generation \u003cstrong\u003eR-454B\u003c\/strong\u003e refrigerant has a global warming potential markedly lower than the fluids it replaces.\u003c\/p\u003e\u003ch3\u003eReading SEER2, EER2, HSPF2 and COP\u003c\/h3\u003e\u003cp\u003eThe 24.0 \u003cstrong\u003eSEER2\u003c\/strong\u003e sums up \u003cstrong\u003ecooling\u003c\/strong\u003e efficiency over an entire season. The 13.2 \u003cstrong\u003eEER2\u003c\/strong\u003e measures it in the hottest condition. The 10.7 \u003cstrong\u003eHSPF2\u003c\/strong\u003e sums up the \u003cstrong\u003eheating\u003c\/strong\u003e season, the one that counts most on a Quebec bill. \u003cstrong\u003eCOP\u003c\/strong\u003e is the most telling: it is the amount of heat delivered for each unit of electricity consumed. An electric baseboard delivers one for one; the heat pump delivers more at each of the published points.\u003c\/p\u003e\u003ch3\u003eThe $4,200 LogisVert grant\u003c\/h3\u003e\u003cp\u003eThe system is listed in Hydro-Québec's \u003cstrong\u003eLogisVert\u003c\/strong\u003e program, with \u003cstrong\u003e$4,200\u003c\/strong\u003e for the owner of an existing home, according to the list in effect on the installation date.

The condenser then goes on a stand or a wall bracket, above the snow line and out of the path of snow falling from the roof. In a bungalow, the three refrigerant line sets run along the facade under a finishing cover or pass, insulated, through the attic to reach heads mounted on interior walls. Each head has its drain, by gravity or through a condensate pump depending on the route. The condenser is wired to a \u003cstrong\u003ededicated circuit\u003c\/strong\u003e after checking the electrical panel. Since R-454B is mildly flammable, each connection is made according to its rules, followed by commissioning: leak test, vacuum, a check of all three zones and programming the remotes with you.\u003c\/p\u003e\u003ch3\u003eMaintenance\u003c\/h3\u003e\u003cp\u003eThe filters of the three heads are rinsed every two weeks in season. The condenser must stay clear of snow, ice and leaves, with no cover in winter. Plan an annual \u003cstrong\u003eHVAC maintenance\u003c\/strong\u003e visit for the coils, blower wheels, drains and electrical connections. In winter, white vapour during defrost and a short pause in heating are normal.
