With baseboards, each area still keeps its own heater, its own thermostat and its own swings: cold near the patio door, warm above the stove, lukewarm in the middle. The \u003cstrong\u003eWall-Mounted Heat Pump ARCOAIRE 16.8 SEER | 18,000 BTU - R410A\u003c\/strong\u003e treats the space as a whole. A single well-placed head covers the kitchen, dining room and living room, and its \u003cstrong\u003einverter compressor\u003c\/strong\u003e modulates its output with the season rather than running flat out.\u003c\/p\u003e\u003cp\u003eIts certified ratings are \u003cstrong\u003e18.3 SEER2\u003c\/strong\u003e, \u003cstrong\u003e9.9 EER2\u003c\/strong\u003e and \u003cstrong\u003e8.7 HSPF2\u003c\/strong\u003e. These figures, published for the exact pairing we install, are the ones to use when comparing it with other units.\u003c\/p\u003e\u003ch3\u003eFor the open-plan living area\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003e18,000 BTU\/h\u003c\/strong\u003e size targets spaces where several functions share one volume: a kitchen open to the dining and living rooms, the ground floor of a two-storey house whose partitions have been removed, an open-plan condo with a wall of windows, or a family room in the basement. It is also the size to consider when a smaller unit would be borderline in a room with strong afternoon sun.\u003c\/p\u003e\u003cp\u003eFloor area alone does not determine the right capacity. An unusual ceiling height, a mezzanine, large patio doors, the orientation of the windows and the quality of the exterior wall insulation weigh just as much. A well-insulated open area in a recent building and the same area in a pre-war house do not have the same needs. The load calculation done during the visit settles the question, and we propose another size if this one is not the right fit.\u003c\/p\u003e\u003ch3\u003eMoving air from one end to the other\u003c\/h3\u003e\u003cp\u003eIn a large open volume, the location of the head determines the result. We prefer to mount it high, on a short wall or at one end of the space, so that the airflow travels the length of the room instead of hitting a nearby wall. We avoid blowing directly on the table or the sofa, and we take obstacles into account: beams, ceiling drops, tall kitchen cabinets, an island with a range hood.\u003c\/p\u003e\u003cp\u003eThe adjustable louvres do the rest: toward the ceiling in cooling, so the cool air settles gently over the whole area, and toward the floor in heating, so warm air does not collect up high. Closed rooms that open onto the open area, such as a bedroom or bathroom, receive only part of this air, and only with the door open; they keep their baseboards, or we present another solution if needed.\u003c\/p\u003e\u003ch3\u003eWhat happens to the baseboards\u003c\/h3\u003e\u003cp\u003eReplacing baseboards does not mean tearing them out. In most open-plan spaces, we recommend keeping them as backup heat, with their thermostats set a few degrees below the heat pump's set point. They then stay off for most of the winter and only come on during deep cold, or when a corner far from the head falls behind. The heat pump becomes the main heating; the baseboards become the reserve.\u003c\/p\u003e\u003cp\u003eThis split has a practical advantage: one unit to set for the whole space, and smaller differences between the window and the kitchen. The day you redo the floor or the cabinets, there will always be time to remove a baseboard that is no longer needed.\u003c\/p\u003e\u003ch3\u003eSummer in an open kitchen\u003c\/h3\u003e\u003cp\u003eAn open kitchen adds its own heat to the sun's: oven, stove, dishwasher, guests around the table. In \u003cstrong\u003ecooling\u003c\/strong\u003e mode, the \u003cstrong\u003e9.9 EER2\u003c\/strong\u003e rating measures efficiency in high heat, when demand is at its peak, and the \u003cstrong\u003e18.3 SEER2\u003c\/strong\u003e rating measures efficiency over the whole season. During a heat wave, when the sun hits the windows late in the day and dinner is cooking, the compressor speeds up; once the space has cooled, it slows down and holds the temperature without abrupt stops.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDehumidification\u003c\/strong\u003e follows the same principle. As long as the unit runs at low speed, the indoor coil condenses moisture from the air, and the drain carries it outside. Cooking steam and the humidity of July evenings are removed continuously, which makes the open area more comfortable at the same temperature. The range hood is still needed to remove odours and grease at the source: the heat pump does not replace it.\u003c\/p\u003e\u003ch3\u003eHow an inverter heat pump works\u003c\/h3\u003e\u003cp\u003eA \u003cstrong\u003ewall-mounted heat pump\u003c\/strong\u003e moves heat instead of producing it. In winter, \u003cstrong\u003eR-410A\u003c\/strong\u003e refrigerant captures the heat contained in the outdoor air, even when it is cold; the compressor concentrates it, and the indoor unit spreads it through the open area. In summer, the cycle reverses and the heat from the house is rejected outdoors.\u003c\/p\u003e\u003cp\u003eThe \u003cstrong\u003evariable-speed\u003c\/strong\u003e compressor adjusts its speed continuously instead of starting and stopping. In a large volume, the difference is noticeable: an all-or-nothing unit lets the far end of the room cool down between cycles, then blows hard to catch up, while an inverter unit keeps a steady airflow that reaches the whole area. R-410A is a proven refrigerant, well known to refrigeration technicians, which makes long-term service easier.\u003c\/p\u003e\u003ch3\u003eThe published winter points\u003c\/h3\u003e\u003cp\u003eFor heating, we only report the measured points. The certificate lists \u003cstrong\u003e10,500 BTU\/h at -8 °C\u003c\/strong\u003e (17 °F), about 58% of the nominal size, and \u003cstrong\u003e10,100 BTU\/h at -15 °C\u003c\/strong\u003e (5 °F), about 56%, with a \u003cstrong\u003eCOP of 1.84\u003c\/strong\u003e at that last point. The two points are measured separately; we report each one as published.\u003c\/p\u003e\u003cp\u003eThese figures can be read two ways. First, the unit keeps heating efficiently in deep cold: at -15 °C, it still delivers close to two units of heat for each unit of electricity consumed, compared with just one for a baseboard. Second, its capacity drops as the temperature falls, like that of any heat pump. That is why we size the open area with the cold days in mind, and why the baseboards kept as backup still make sense in January.\u003c\/p\u003e\u003ch3\u003eSEER2, EER2, HSPF2 and COP, in plain terms\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003cstrong\u003eSEER2 (18.3)\u003c\/strong\u003e: cooling efficiency over the whole summer.

We measure the open area, note the ceiling height, the glazed area and the condition of the insulation, then we do a \u003cstrong\u003eload calculation\u003c\/strong\u003e. We then choose the wall for the head with you based on air circulation, and the location of the outdoor unit based on the line route, snow and the neighbours. The written quote describes all of this before anything is signed.\u003c\/p\u003e\u003ch3\u003eInstallation day\u003c\/h3\u003e\u003cp\u003eThe indoor unit is secured to the framing, with a drainage slope for condensate. The outdoor unit goes on a ground or wall stand, \u003cstrong\u003eabove the snow line\u003c\/strong\u003e, clear of snow falling from roofs and away from bedroom windows, including the neighbours'. The \u003cstrong\u003erefrigerant lines\u003c\/strong\u003e, communication cable and drain go through a single opening, sealed on both sides, and a line cover can finish the run on the facade.\u003c\/p\u003e\u003cp\u003eThe system needs a \u003cstrong\u003ededicated circuit\u003c\/strong\u003e at the electrical panel: we check the panel capacity during the visit, and we install a disconnect near the outdoor unit. At \u003cstrong\u003ecommissioning\u003c\/strong\u003e, the refrigerant circuit is put under vacuum and leak-checked before the valves are opened. We test heating, cooling and drain flow, then show you how to set the unit and aim the louvres for each season.\u003c\/p\u003e\u003ch3\u003eMaintaining a heat pump near the kitchen\u003c\/h3\u003e\u003cp\u003eRinse the indoor filters every two weeks in season; near a kitchen, check them more often, since cooking grease sticks to them along with dust. 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. In winter, white vapour during defrost and a short pause in heating are normal.
