The south-facing one overheats as early as May, the one in the north corner holds the cold all winter, and the main bedroom is only occupied in the evening. The \u003cstrong\u003e3-Zone Heat Pump ARCOAIRE DLCMHB | 24,000 BTU - R410A\u003c\/strong\u003e gives each one its own \u003cstrong\u003ewall head\u003c\/strong\u003e and its own set point, fed by a single \u003cstrong\u003eDLCMHBH24CAK condenser\u003c\/strong\u003e installed outside.\u003c\/p\u003e\n\u003cp\u003eIn this configuration, the \u003cstrong\u003e2-ton\u003c\/strong\u003e condenser serves \u003cstrong\u003e3 zones\u003c\/strong\u003e, which is its maximum of 3. The wall heads intended for it are the \u003cstrong\u003eDLFSHCH09XAK\u003c\/strong\u003e and the \u003cstrong\u003eDLFSHCH12XAK\u003c\/strong\u003e. Its certified ratings are \u003cstrong\u003e22.3 SEER2\u003c\/strong\u003e, \u003cstrong\u003e12.5 EER2\u003c\/strong\u003e and \u003cstrong\u003e9.6 HSPF2\u003c\/strong\u003e.

It also suits a small bungalow whose living room and two bedrooms are separated by a hallway, or a condo whose rooms are not open enough to each other for a single head to do the job. What they have in common: three modest rooms rather than one large open area.\u003c\/p\u003e\n\u003cp\u003eRoof insulation matters a great deal upstairs. Under a well-insulated attic, three heads are generally enough to heat and cool the bedrooms for most of the year. Under an older roof, heat builds up in summer and escapes in winter; we take that into account in the calculation and tell you before signing.\u003c\/p\u003e\n\u003ch3\u003eThree heads on 24,000 BTU: a split that has to be calculated\u003c\/h3\u003e\n\u003cp\u003eThe three heads share the capacity of the same condenser. During the day, when only one bedroom is occupied, all the available capacity can go to it. At night, all three rooms call at once, and that moment drives our sizing. We calculate each bedroom separately rather than dividing the capacity into three equal shares.\u003c\/p\u003e\n\u003cp\u003eThe choice of heads follows from that. The \u003cstrong\u003eDLFSHCH09XAK\u003c\/strong\u003e, the smallest, suits children's rooms and the office. The \u003cstrong\u003eDLFSHCH12XAK\u003c\/strong\u003e goes to the main bedroom or the most exposed room. The exact combination is confirmed during the visit. With three zones, every connection on the condenser is used: a fourth room would require another unit.\u003c\/p\u003e\n\u003ch3\u003eSummer nights under the roof\u003c\/h3\u003e\n\u003cp\u003eSummer is often what pushes our clients to equip the upper floor. The sun heats the roof all day, and the heat stays in the bedrooms long after sunset. With a head in each bedroom, cooling starts where you sleep, without having to cool the whole house to reach the upper floor.\u003c\/p\u003e\n\u003cp\u003eThe \u003cstrong\u003einverter compressor\u003c\/strong\u003e runs for long periods at low speed instead of starting and stopping. The air passes more slowly over the cold coil, which removes more moisture. The bedrooms stay cool and dry, without the cold blast of a window air conditioner. Each head's dehumidification mode also helps on muggy July days.\u003c\/p\u003e\n\u003ch3\u003eHeating the upper floor in winter\u003c\/h3\u003e\n\u003cp\u003eThe certificate lists \u003cstrong\u003e18,000 BTU\/h at -8 °C\u003c\/strong\u003e (17 °F) and \u003cstrong\u003e17,000 BTU\/h at -15 °C\u003c\/strong\u003e (5 °F), with a \u003cstrong\u003eCOP of 1.83\u003c\/strong\u003e at the -15 °C point. The two points are measured separately; we report each one as published.\u003c\/p\u003e\n\u003cp\u003eAt -15 °C, the condenser therefore keeps 71% of its nominal size, and its three heads share that capacity. On a well-insulated upper floor, that is enough for most winter nights. During deep cold, the existing \u003cstrong\u003eelectric baseboards\u003c\/strong\u003e stay in place as backup and only come on when the heat pump is no longer enough. A COP of 1.83 means that each kilowatt-hour consumed at that temperature returns 1.83 kilowatt-hours of heat, where a baseboard returns one.\u003c\/p\u003e\n\u003cp\u003eIn cold, humid weather, the condenser runs \u003cstrong\u003edefrost cycles\u003c\/strong\u003e lasting a few minutes. The heads then stop blowing warm air and a cloud of vapour rises from the outdoor unit. This is how a heat pump normally works in winter.\u003c\/p\u003e\n\u003ch3\u003eHow the condenser serves three rooms at once\u003c\/h3\u003e\n\u003cp\u003eThe condenser meters the \u003cstrong\u003eR-410A refrigerant\u003c\/strong\u003e sent to each head according to its demand. A bedroom that reaches its set point slows down while the others keep going. Shutting off an unoccupied zone entirely, a guest room for example, leaves the other two running normally.\u003c\/p\u003e\n\u003cp\u003eOne rule applies to every system of this type: the heads on the same condenser work in the same mode. They all heat or they all cool. For a bedroom floor, which lives through the same season from one room to the next, this rule almost always goes unnoticed.\u003c\/p\u003e\n\u003ch3\u003eReading this system's ratings\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003eSEER2\u003c\/strong\u003e of 22.3 measures cooling efficiency over a whole summer; it is the rating to look at for bedrooms under the roof. The \u003cstrong\u003eEER2\u003c\/strong\u003e of 12.5 measures cooling in hot weather, at full load, during heat waves. The \u003cstrong\u003eHSPF2\u003c\/strong\u003e of 9.6 measures heating efficiency over the whole cold season; in Quebec, it is the rating that weighs most on the bill. Finally, the \u003cstrong\u003eCOP\u003c\/strong\u003e gives the efficiency at a specific temperature.\u003c\/p\u003e\n\u003cp\u003eThese figures come from certificate \u003cstrong\u003eAHRI 207642990\u003c\/strong\u003e, as published by ENERGY STAR.\u003c\/p\u003e\n\u003ch3\u003eThe $2,160 LogisVert grant\u003c\/h3\u003e\n\u003cp\u003eThe system is listed in Hydro-Québec's \u003cstrong\u003eLogisVert\u003c\/strong\u003e program, with \u003cstrong\u003e$2,160\u003c\/strong\u003e for the owner of an existing home, according to the list in effect on the installation date.

For an upper floor, the three routes are planned together: on the facade, grouped in a painted line cover that follows the lines of the house, or indoors when a closet or the attic allows it. We show you the route before drilling.\u003c\/p\u003e\n\u003cp\u003eIn a bedroom, the head's location matters as much as its size. We mount it high on the wall so the air sweeps the room without blowing directly on the bed, and far enough from curtains and tall furniture for the air to circulate freely. When the exterior wall allows it, the head goes there: the line route is shorter and the drilling simpler.\u003c\/p\u003e\n\u003cp\u003eEach head also has its own \u003cstrong\u003econdensate drain\u003c\/strong\u003e. When a natural slope to the outside is possible, the water drains by gravity. Otherwise, a small condensate pump becomes necessary; we determine that during the visit, room by room.\u003c\/p\u003e\n\u003ch3\u003eThe outdoor unit and the electrical work\u003c\/h3\u003e\n\u003cp\u003eThe condenser is installed above the snow line, on a wall bracket or a stand, away from snow sliding off the roof and from the neighbours' bedroom windows. It is connected to a \u003cstrong\u003ededicated circuit\u003c\/strong\u003e, which we check at the panel during the visit. At commissioning, we pull a vacuum and run a leak test, check each zone, then set up the remotes with you.\u003c\/p\u003e\n\u003ch3\u003eMaintaining three heads\u003c\/h3\u003e\n\u003cp\u003eThree heads means three sets of filters to rinse every two weeks in season; they come out by hand. Outside, keep the condenser clear of snow and leaves, without covering it in winter. One \u003cstrong\u003eHVAC\u003c\/strong\u003e maintenance visit per year cleans the coils, fans and drains of all three heads and checks the connections.
