The \u003cstrong\u003e2-Zone Heat Pump ARCOAIRE D5CMHA | 30,000 BTU - R454B\u003c\/strong\u003e is designed for that case: a large open ground floor and a finished basement, or the two full floors of a semi-detached house.

Upstairs, large windows, cooking and the afternoon sun drive up the cooling load; in winter, the glass area and exterior doors make it the zone most exposed to the cold. Downstairs, the foundation walls keep a stable temperature: the basement stays cool in summer, but humid, and its cold floor calls for heat a good part of the year. A single wall unit placed upstairs does not go down the stairs; one head per level gives each its own set point.\u003c\/p\u003e\u003cp\u003eThe size of each head comes from the \u003cstrong\u003eload calculation\u003c\/strong\u003e: floor area, ceiling height, windows, insulation of the foundation walls. A seventies house with an uninsulated basement does not have the needs of a recent build; we measure before we propose.\u003c\/p\u003e\u003ch3\u003eThe D5FSHAH18XAK head for the large room\u003c\/h3\u003e\u003cp\u003eIn an open area, the question is not only capacity but how far the air carries. The D5FSHAH18XAK head, the largest on the list, suits rooms where the air must travel the full length between the living room and the dining room. We preferably mount it on a short wall, so the airflow runs along the room rather than across it, making sure an island, a beam or a soffit does not cut it off. The adjustable louvers then direct the flow: upward in cooling, downward in heating.\u003c\/p\u003e\u003ch3\u003eThe basement, the zone people overlook\u003c\/h3\u003e\u003cp\u003eA basement heated only by baseboards often remains the least pleasant room in the house. The basement head is mounted high on the wall, so warm air is pushed toward the floor in winter, and it offers an advantage in summer: the \u003cstrong\u003edehumidification\u003c\/strong\u003e mode removes the moisture that builds up against the foundation, without cooling a room that is already cool. For a family room, a home theatre or a basement office, that is often the difference between a room you avoid and a room you use.\u003c\/p\u003e\u003ch3\u003eJanuary cold according to the certificate\u003c\/h3\u003e\u003cp\u003eA glassed-in open area is the first zone to cool down when the temperature plunges. This system's 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, two values above the nominal 30,000 BTU size.

For two zones, this reserve means a heat pump that keeps carrying most of the heating through the usual cold of the \u003cstrong\u003eMontreal\u003c\/strong\u003e area. During extreme cold snaps, the existing baseboards serve as backup.\u003c\/p\u003e\u003ch3\u003eTwo zones today, up to four tomorrow\u003c\/h3\u003e\u003cp\u003eThe D5CMHAH30EAK accepts up to four heads. With two zones, two ports remain free for an upstairs bedroom, an office or a room added later. The addition remains possible provided the full set of heads stays within the combinations the manufacturer allows; that is why we choose the first two heads with what might follow in mind. We also place the condenser and plan the line route so that nothing has to be redone when a zone is added.\u003c\/p\u003e\u003ch3\u003eOne condenser for two zones, rather than two units\u003c\/h3\u003e\u003cp\u003eYou could get two zones with two independent wall-mounted heat pumps. Multi-zone has other strengths: only one unit to clear of snow outside, only one \u003cstrong\u003ededicated circuit\u003c\/strong\u003e at the panel, only one maintenance visit for the condenser. On the other hand, both heads work in the same mode at any given time, heating or cooling, and a condenser shutdown affects both zones at once. For a home whose two zones follow the same seasons, the balance clearly tips toward multi-zone.\u003c\/p\u003e\u003ch3\u003eThe ratings, without jargon\u003c\/h3\u003e\u003cp\u003eThe 24.0 \u003cstrong\u003eSEER2\u003c\/strong\u003e measures seasonal \u003cstrong\u003ecooling\u003c\/strong\u003e efficiency; the 13.2 \u003cstrong\u003eEER2\u003c\/strong\u003e isolates the hottest days, when the glassed-in open area works hardest.
