Each closed room gets its own head, and the kitchen benefits from the living-room head.\u003c\/p\u003e\n\u003cp\u003eThe result depends on the insulation. In a recent or renovated home, the three heads can become the main heat source.

The bedrooms get the \u003cstrong\u003eMHWAL09DACFC\u003c\/strong\u003e, smaller and well suited to a closed room used mostly at night. The exact combination is confirmed after the load calculation.\u003c\/p\u003e\n\u003cp\u003eIn a small home, the location of each head is decided carefully. In the living room, we place it so it blows toward the open kitchen without aiming straight at the sofa, and away from the stove, whose heat would skew the temperature reading. In a bedroom, the head goes high on the wall, preferably on an exterior wall to shorten the lines, with airflow that sweeps the room without falling on the bed. We show you each location before drilling.\u003c\/p\u003e\n\u003cp\u003eThe three heads share the condenser's capacity. With 3 zones out of a maximum of 3, every connection is used: the system covers the home as it is, with no room for a fourth space.

During the day, the bedrooms are empty: their set point can stay a little lower, and the condenser concentrates its capacity on the living room. In the evening, demand moves back to the bedrooms. The \u003cstrong\u003einverter compressor\u003c\/strong\u003e follows this movement without abrupt starts, metering the \u003cstrong\u003eR-410A refrigerant\u003c\/strong\u003e sent to each head according to its demand.\u003c\/p\u003e\n\u003cp\u003eA single rule frames this operation: the three heads work in the same mode, heating or cooling, as on any multi-zone system of this type.

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 210605813\u003c\/strong\u003e, published by NEEP.\u003c\/p\u003e\n\u003ch3\u003eThe baseboards, kept in reserve\u003c\/h3\u003e\n\u003cp\u003eThe certificate does not publish a point colder than -15 °C.

In every case, the insulation of the exterior walls and the quality of the windows matter as much as the floor area; an old plex does not have the same envelope as a renovated unit, and the load calculation takes that into account.\u003c\/p\u003e\n\u003ch3\u003eThree heads, from front to back\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003eMHWAL18DACFC\u003c\/strong\u003e, the largest of the three intended heads, usually goes in the double living room, the largest and most glazed room.

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. The large glazed areas common in these living rooms add losses in winter and heat gains in summer. 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. The other two zones serve the bedrooms. The load calculation accounts for the room's actual volume, not just its floor area.\u003c\/p\u003e\n\u003ch3\u003eThe MHWAL24DACFC in a large volume\u003c\/h3\u003e\n\u003cp\u003eFor the living room, we plan the \u003cstrong\u003eMHWAL24DACFC\u003c\/strong\u003e, the largest of the intended heads. It is not installed at the top of the wall, where the air is already warm, but at a height that lets it blow toward the occupied zone and remains accessible for filter maintenance. It blows along the length of the room, toward the windows rather than against a wall.\u003c\/p\u003e\n\u003cp\u003eA ceiling fan helps a great deal in these rooms. Set to push air gently downward in winter, it brings the heat collected under the ridge back to the occupied zone and makes the head's work more effective. If your living room already has one, we take it into account when choosing the location.\u003c\/p\u003e\n\u003ch3\u003eThe two bedrooms\u003c\/h3\u003e\n\u003cp\u003eThe bedrooms get smaller heads: the \u003cstrong\u003eMHWAL12DACFC\u003c\/strong\u003e for the main bedroom, the \u003cstrong\u003eMHWAL09DACFC\u003c\/strong\u003e for a child's or guest room. Closed at night, they need their own set point, independent of the living room's.\u003c\/p\u003e\n\u003cp\u003eThe three heads share the condenser's capacity. During the day, the living room takes the largest share; at night, the bedrooms do. With 3 zones out of a maximum of 5, two connections remain free to equip another bedroom or an office later, after checking the remaining capacity.\u003c\/p\u003e\n\u003cp\u003eA mezzanine open to the living room is a special case. It benefits from the large room's air in winter, but it collects heat under the roof in summer and quickly becomes the hottest zone in the house. During the visit, we assess whether the living-room head is enough to cover it or whether it deserves its own head on one of the free connections.\u003c\/p\u003e\n\u003ch3\u003eWinter according to the certificate\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\u003eA COP of 2.00 means that at -15 °C, each kilowatt-hour consumed returns two kilowatt-hours of heat, where an electric baseboard returns one. At -8 °C, the ratio rises to 2.30. 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 and defrost\u003c\/h3\u003e\n\u003cp\u003eThe certificate does not publish a point colder than -15 °C. In a heavily glazed living room, backup remains worthwhile: the existing \u003cstrong\u003eelectric baseboards\u003c\/strong\u003e or fireplace stay in place, set slightly below the heads' set point, and take over during extreme cold. In cold, humid weather, the condenser also runs \u003cstrong\u003edefrost cycles\u003c\/strong\u003e of a few minutes; the heads then stop blowing warm air and a cloud of vapour rises from the outdoor unit. This is normal.\u003c\/p\u003e\n\u003ch3\u003eThe inverter compressor and its three zones\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003einverter compressor\u003c\/strong\u003e varies its speed according to demand and meters the \u003cstrong\u003eR-410A refrigerant\u003c\/strong\u003e sent to each head. In the living room, it runs for long periods at moderate speed, which keeps the air moving continuously and limits stratification. Shutting off an unoccupied bedroom leaves the other two zones running normally. As on any multi-zone system of this type, the three heads work in the same mode, heating or cooling.\u003c\/p\u003e\n\u003ch3\u003eSummer under a cathedral ceiling\u003c\/h3\u003e\n\u003cp\u003eIn cooling, the system is built around a nominal size of \u003cstrong\u003e48,000 BTU\/h\u003c\/strong\u003e for the three zones. In a tall, glassy living room, sunny afternoons are what count: blinds on the upper windows lighten the load considerably. Extended low-speed operation removes moisture from the air, and each head offers a dehumidification mode for muggy days. The bedrooms, for their part, are cooled for the night without cooling the whole living room.\u003c\/p\u003e\n\u003ch3\u003eThe 21.8 SEER2, 11.7 EER2 and 9.8 HSPF2 ratings\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003eHSPF2\u003c\/strong\u003e of 9.8 measures heating efficiency over the whole cold season; in Quebec, it is the rating that weighs most on the bill. The \u003cstrong\u003eSEER2\u003c\/strong\u003e of 21.8 measures cooling efficiency over a whole summer, and the \u003cstrong\u003eEER2\u003c\/strong\u003e of 11.7 measures cooling at full load, in hot weather. The \u003cstrong\u003eCOP\u003c\/strong\u003e expresses efficiency at a specific temperature: it is the ratio between heat delivered and electricity consumed.\u003c\/p\u003e\n\u003ch3\u003eThe $4,320 LogisVert grant\u003c\/h3\u003e\n\u003cp\u003eThe system is listed in Hydro-Québec's \u003cstrong\u003eLogisVert\u003c\/strong\u003e program, with \u003cstrong\u003e$4,320\u003c\/strong\u003e for the owner of an existing home, according to the list in effect on the installation date.
