The \u003cstrong\u003e2-Zone Heat Pump ARCOAIRE D5CMHA | 24,000 BTU - R454B\u003c\/strong\u003e targets exactly those two rooms.

The certificate still lists its capacity at \u003cstrong\u003e-30 °C\u003c\/strong\u003e, and the system qualifies for a \u003cstrong\u003e$3,480 LogisVert grant\u003c\/strong\u003e.\u003c\/p\u003e\u003ch3\u003eLiving room and primary bedroom: the most common pair\u003c\/h3\u003e\u003cp\u003eIn a bungalow, a semi-detached house or a 5 ½, the living room and kitchen often form a single large room, and the primary bedroom sits at the end of the hallway. A single wall unit in the living room does not reach the bedroom once the door is closed; two independent units mean two condensers outside. This system settles the question with one condenser and two heads, each with its own set point.\u003c\/p\u003e\u003cp\u003eIt is also the most common configuration for replacing \u003cstrong\u003eelectric baseboard\u003c\/strong\u003e heating in the living spaces. The baseboards stay in place as backup for deep cold and for secondary rooms, but the \u003cstrong\u003eheat pump\u003c\/strong\u003e takes on most of the season's heating. Heat is spread by the head's fan rather than by a hot strip along the wall, which evens out the temperature between floor and ceiling. The real size of each room, its insulation and its exposure decide the head size; we measure them during the visit.\u003c\/p\u003e\u003ch3\u003eThree head sizes for two rooms of different sizes\u003c\/h3\u003e\u003cp\u003eThe number in the middle of each head's model code indicates its size: 06 for the most compact, 09 for the intermediate size, 12 for the largest on this list. Since the two rooms involved are almost never the same size, the combination is chosen room by room: the largest head in the open area, a smaller head in the bedroom. Oversizing a bedroom head does not make it more comfortable; it cycles more often and dehumidifies less well.\u003c\/p\u003e\u003cp\u003eThe total of connected heads must also stay within the combinations the manufacturer allows for this condenser. That check, made during the load calculation, is what lets each room receive its share when both zones call at the same time.\u003c\/p\u003e\u003ch3\u003eThe free port: preparing the third zone at installation\u003c\/h3\u003e\u003cp\u003eThe D5CMHAH24DAK accepts a third head. If a basement office, a child's bedroom or a playroom is added in a few years, the zone can be connected without changing the condenser, provided the combination of three heads remains allowed. We take this into account from the first installation: the condenser location, the planned route for a third line and the capacity of the electrical circuit are chosen so the addition can be done cleanly. If you already know a third room will follow, say so during the visit; the choice of the first two heads may depend on it.\u003c\/p\u003e\u003ch3\u003eInverter, R-454B and sharing between heads\u003c\/h3\u003e\u003cp\u003eThe condenser does not work on an all-or-nothing basis. Its \u003cstrong\u003einverter compressor\u003c\/strong\u003e speeds up when both heads call on a cold morning and slows down when a single room is holding its set point in the afternoon. It meters the refrigerant sent to each head according to its demand, then settles at low speed, where it consumes the least. Both heads do, however, work in the same mode at any given time, heating or cooling, each at its own temperature.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eR-454B\u003c\/strong\u003e is the new-generation refrigerant adopted for residential heat pumps, with a global warming potential markedly lower than that of the fluids it replaces. It is classified as mildly flammable and calls for installers who apply its handling rules.\u003c\/p\u003e\u003ch3\u003eWhat the certificate shows for winter\u003c\/h3\u003e\u003cp\u003eThe certificate lists \u003cstrong\u003e23,600 BTU\/h at -8 °C\u003c\/strong\u003e and \u003cstrong\u003e25,000 BTU\/h at -15 °C\u003c\/strong\u003e. The two points are measured separately; we report each one as published, even though the value at -15 °C is higher than the one at -8 °C.\u003c\/p\u003e\u003cul\u003e\u003cli\u003eCOP of 2.50 at the -8 °C point (17 °F)\u003c\/li\u003e\u003cli\u003eCOP of 2.00 at the -15 °C point (5 °F)\u003c\/li\u003e\u003cli\u003eMaximum capacity at -30 °C: 14,000 BTU\/h, COP of 1.30\u003c\/li\u003e\u003cli\u003eHeating certified down to -30 °C\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eFor the living room and bedroom of a well-insulated home in the \u003cstrong\u003eMontreal\u003c\/strong\u003e area, these points cover the vast majority of winter days. The closer the temperature gets to -30 °C, the lower the published capacity; the baseboards you keep then take over in the most exposed rooms. These figures come from certificate \u003cstrong\u003eAHRI 215357131\u003c\/strong\u003e, published by NEEP.\u003c\/p\u003e\u003ch3\u003eReading the 24.0 SEER2, 13.0 EER2 and 10.0 HSPF2 ratings\u003c\/h3\u003e\u003cp\u003eThese three ratings answer three different questions. \u003cstrong\u003eSEER2\u003c\/strong\u003e tells you what \u003cstrong\u003ecooling\u003c\/strong\u003e costs over a whole season, from mild mornings to heat-wave afternoons. \u003cstrong\u003eEER2\u003c\/strong\u003e isolates the hottest condition: it is the efficiency when the sun is beating on the living room windows. \u003cstrong\u003eHSPF2\u003c\/strong\u003e sums up the \u003cstrong\u003eheating\u003c\/strong\u003e season, the one that weighs most on the bill in Quebec. \u003cstrong\u003eCOP\u003c\/strong\u003e, published at each cold point, completes the picture: at 2.50, the heat pump delivers two and a half times more heat than the electricity it consumes, where a baseboard delivers exactly what it consumes.\u003c\/p\u003e\u003ch3\u003eSummer: cooling and humidity in the open area\u003c\/h3\u003e\u003cp\u003eAn open area piles up heat gains: cooking, appliances, large windows. The living room head should therefore be placed to push air along the length of the room, ideally on a wall from which the airflow does not aim straight at the counter or the sofa. In the bedroom, the priority is different: gentle airflow and dry air for sleeping. The variable-speed compressor runs for long periods at low speed, which gives the coil time to remove moisture, and the \u003cstrong\u003edehumidification\u003c\/strong\u003e mode is useful on muggy days when the temperature does not justify full cooling.\u003c\/p\u003e\u003ch3\u003eThe $3,480 LogisVert grant\u003c\/h3\u003e\u003cp\u003eThe system is listed in Hydro-Québec's \u003cstrong\u003eLogisVert\u003c\/strong\u003e program, with \u003cstrong\u003e$3,480\u003c\/strong\u003e for the owner of an existing home, according to the list in effect on the installation date.

Each head is installed on a wall chosen for air distribution, then connected to the condenser by its own refrigerant line set, communication cable and drain. Outside, the lines run in a finishing cover; the drain flows by gravity, or through a small condensate pump when the route requires it. The condenser is connected to a \u003cstrong\u003ededicated circuit\u003c\/strong\u003e with a disconnect, after checking the electrical panel. At commissioning, we perform the leak test, the vacuum, a check of each zone and programming of the remotes with you.\u003c\/p\u003e\u003ch3\u003eSimple maintenance, two heads at a time\u003c\/h3\u003e\u003cp\u003eThe head filters are rinsed in lukewarm water every two weeks during the heating and cooling seasons. Outside, the condenser must stay clear: no snow piled against the sides, no leaves in the coil, no cover in winter. An annual \u003cstrong\u003eHVAC maintenance\u003c\/strong\u003e visit cleans the coils and the heads' blower wheels and checks the drain flow and the electrical connections. During cold spells, white vapour during defrost and a short pause in heating are normal.
