Too hot under the July sun, chilly as soon as night falls in October, they escape the heating of the rest of the house. The \u003cstrong\u003eWall-Mounted Heat Pump ARCOAIRE Performance | 12,000 BTU 115V - R454B\u003c\/strong\u003e gives them their own \u003cstrong\u003ecooling\u003c\/strong\u003e and their own heating, with a simplified electrical connection.\u003c\/p\u003e\n\u003cp\u003eIt runs on a \u003cstrong\u003e115 V\u003c\/strong\u003e circuit, a useful option when the electrical panel has no room left for a double breaker. Its certified ratings are \u003cstrong\u003e21.4 SEER2\u003c\/strong\u003e, \u003cstrong\u003e10.0 EER2\u003c\/strong\u003e and \u003cstrong\u003e8.7 HSPF2\u003c\/strong\u003e, and it runs on \u003cstrong\u003eR-454B\u003c\/strong\u003e refrigerant.\u003c\/p\u003e\n\u003ch3\u003eGlassed-in and added rooms, a load of their own\u003c\/h3\u003e\n\u003cp\u003eA room with a lot of glass behaves very differently from a bedroom or a living room. During the day, the sun brings in a large amount of heat, even in spring. At night and in winter, glass lets heat escape much faster than an insulated wall. An addition built at the back of a house often has three exterior walls, a floor on piers or on a slab, and ducts or baseboards that were not designed for it.\u003c\/p\u003e\n\u003cp\u003eA nominal capacity of \u003cstrong\u003e12,000 BTU\/h\u003c\/strong\u003e typically suits a good-sized addition or a well-built sunroom, with quality glass and proper insulation in the floor and roof. For a heavily glazed or older sunroom, we run a precise load calculation during the visit and tell you plainly what the heat pump will be able to cover in winter, and what it will not.\u003c\/p\u003e\n\u003ch3\u003eWhy 115 V simplifies the connection\u003c\/h3\u003e\n\u003cp\u003eAdded rooms are often far from the main panel, or fed by a small subpanel. Most wall-mounted heat pumps need a double breaker, which takes up two spaces; when the panel or subpanel is full, that detail can complicate the whole project. A \u003cstrong\u003e115 V\u003c\/strong\u003e unit connects to a single breaker, which leaves more flexibility to find room.\u003c\/p\u003e\n\u003cp\u003eIt still needs a \u003cstrong\u003ededicated circuit\u003c\/strong\u003e, and the panel's total capacity must allow it. We check this during the visit, before proposing anything. Once in place, nothing distinguishes how it runs from a model connected differently: the \u003cstrong\u003evariable-speed compressor\u003c\/strong\u003e modulates its output the same way.\u003c\/p\u003e\n\u003ch3\u003eSummer under the glass\u003c\/h3\u003e\n\u003cp\u003eIn \u003cstrong\u003ecooling\u003c\/strong\u003e mode, the nominal capacity is \u003cstrong\u003e12,000 BTU\/h\u003c\/strong\u003e. The \u003cstrong\u003e10.0 EER2\u003c\/strong\u003e rating measures efficiency at the peak of the heat, when the sun hits the glass directly; the SEER2 rating of 21.4 sums up efficiency over the whole season. The variable-speed compressor adjusts its speed as the sun moves: it speeds up in the afternoon and slows down in the evening.\u003c\/p\u003e\n\u003cp\u003eBlinds or exterior shades greatly reduce the load to fight, and the heat pump handles the rest. Running at low speed, the indoor coil condenses moisture from the air, which provides continuous \u003cstrong\u003edehumidification\u003c\/strong\u003e and prevents the fogging and heavy air typical of glassed-in rooms in summer.\u003c\/p\u003e\n\u003ch3\u003eWinter, certified figures\u003c\/h3\u003e\n\u003cp\u003eThe certificate lists \u003cstrong\u003e9,000 BTU\/h at -8 °C\u003c\/strong\u003e (17 °F), about 75% of nominal capacity, with a \u003cstrong\u003eCOP of 2.24\u003c\/strong\u003e, and \u003cstrong\u003e7,000 BTU\/h at -15 °C\u003c\/strong\u003e (5 °F), about 58%, with a \u003cstrong\u003eCOP of 1.85\u003c\/strong\u003e. The two points are measured separately; we report each one as published.\u003c\/p\u003e\n\u003cp\u003eIn practice, the heat pump heats the room very efficiently through the fall, the spring and moderate winter days. That is often what turns a three-season sunroom into a room that is truly usable for much of the year.\u003c\/p\u003e\n\u003ch3\u003eBackup for deep cold\u003c\/h3\u003e\n\u003cp\u003eIn deep cold, available capacity drops while the glassed-in room loses heat faster. Backup is therefore still needed to keep a room of this type comfortable in January: a baseboard, a convector or another source already in place. The setting is simple: the heat pump holds the main set point, and the backup thermostat is set a few degrees lower. The backup only switches on when the heat pump is no longer enough.\u003c\/p\u003e\n\u003cp\u003eIf the room is not used in the heart of winter, a reduced set point is enough to keep it above freezing and avoid condensation on the windows, while still benefiting from the heat pump's efficiency.\u003c\/p\u003e\n\u003ch3\u003eInverter and R-454B refrigerant\u003c\/h3\u003e\n\u003cp\u003eA \u003cstrong\u003ewall-mounted heat pump\u003c\/strong\u003e moves heat instead of producing it: in summer, it takes it out of the room; in winter, it draws it from the outdoor air. \u003cstrong\u003eInverter\u003c\/strong\u003e technology lets the compressor change speed instead of running all-or-nothing, which stabilizes the temperature in a room whose load changes hour by hour. \u003cstrong\u003eR-454B\u003c\/strong\u003e is the new-generation refrigerant, with a much lower global warming potential than the previous one; classified A2L, it requires precise installation methods that we apply on every job.\u003c\/p\u003e\n\u003ch3\u003eThe ratings, plainly\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eSEER2 of 21.4\u003c\/strong\u003e: cooling efficiency over the whole season.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eEER2 of 10.0\u003c\/strong\u003e: cooling efficiency at the hottest moment.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eHSPF2 of 8.7\u003c\/strong\u003e: heating efficiency over a full season.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eCOP of 2.24 at -8 °C and 1.85 at -15 °C\u003c\/strong\u003e: heat delivered per unit of electricity, where an electric baseboard delivers one.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThese figures come from certificate \u003cstrong\u003eAHRI 215413218\u003c\/strong\u003e, published by NEEP.\u003c\/p\u003e\n\u003ch3\u003eLogisVert\u003c\/h3\u003e\n\u003cp\u003eThis pairing does not carry an amount on Hydro-Québec's \u003cstrong\u003eLogisVert\u003c\/strong\u003e list of October 19, 2026.

We measure the room, the glass area and its orientation, the insulation of the floor and roof, then run the \u003cstrong\u003eload calculation\u003c\/strong\u003e. In a sunroom, solid walls are rare: the wall head is often mounted on the house's former exterior wall or on a knee wall, always secured to the framing, up high, with a drainage slope for condensate. We choose the location that lets the airflow cover the whole room without aiming directly at the eating area or the armchairs.\u003c\/p\u003e\n\u003ch3\u003eOutdoor unit, lines and commissioning\u003c\/h3\u003e\n\u003cp\u003eThe outdoor unit goes on a ground or wall stand, \u003cstrong\u003eabove the snow line\u003c\/strong\u003e, away from bedroom windows, including the neighbours', and sheltered from snow sliding off roofs. The \u003cstrong\u003erefrigerant lines\u003c\/strong\u003e, the cable and the drain go through a single sealed opening, and a line cover can finish the run. At \u003cstrong\u003ecommissioning\u003c\/strong\u003e, the circuit is evacuated and checked for tightness, then we test cooling, heating and the drain, and set the backup.\u003c\/p\u003e\n\u003ch3\u003eMaintenance and warranty\u003c\/h3\u003e\n\u003cp\u003eRinse the indoor filters every two weeks in season, keep the outdoor unit clear of snow and leaves, and plan annual \u003cstrong\u003eHVAC maintenance\u003c\/strong\u003e of the coils, drain and electrical connections.
