It still runs, but it is noisier, heats less well when it is cold, and the baseboards are working more and more. The \u003cstrong\u003eWall-Mounted Heat Pump ARCOAIRE Performance | 18,000 BTU - R454B\u003c\/strong\u003e is a direct replacement for this kind of unit: a single head for an open kitchen-living area, with today's technology and refrigerant.\u003c\/p\u003e\n\u003cp\u003eIts certified ratings are \u003cstrong\u003e20.3 SEER2\u003c\/strong\u003e, \u003cstrong\u003e11.5 EER2\u003c\/strong\u003e and \u003cstrong\u003e9.1 HSPF2\u003c\/strong\u003e. The system is \u003cstrong\u003eENERGY STAR\u003c\/strong\u003e certified under \u003cstrong\u003eENERGY STAR ID 4478846\u003c\/strong\u003e. It qualifies for a \u003cstrong\u003e$700 LogisVert grant\u003c\/strong\u003e.\u003c\/p\u003e\n\u003ch3\u003eWhen to replace the old unit\u003c\/h3\u003e\n\u003cp\u003eA few signs come up often: the heat pump starts and stops frequently, the outdoor unit has become louder, the room no longer reaches the set point in the first cold spells, or repairs keep piling up. An older unit sometimes uses a previous-generation refrigerant, whose recharges are becoming hard to justify. When a major repair looms on an aging unit, replacement is often the most sensible decision.\u003c\/p\u003e\n\u003cp\u003eThe ideal time to plan the change is before a breakdown, in spring or fall, rather than in the middle of a heat wave or at the first deep cold. A planned replacement gives you time to compare options, confirm the grant and choose when the work happens, instead of taking the first available unit in an emergency.\u003c\/p\u003e\n\u003ch3\u003eWhat has changed since\u003c\/h3\u003e\n\u003cp\u003eRecent wall-mounted heat pumps rely on a \u003cstrong\u003evariable-speed compressor\u003c\/strong\u003e that modulates its output continuously. Instead of alternating between full power and off, it slows down as the room approaches the set point and speeds up when demand rises. Comfort is steadier, and the unit spends most of its time in its most efficient range.\u003c\/p\u003e\n\u003cp\u003eThe ratings have also changed: units are now rated in \u003cstrong\u003eSEER2\u003c\/strong\u003e and \u003cstrong\u003eHSPF2\u003c\/strong\u003e, using test methods more representative of real installation conditions. Finally, the circuit uses \u003cstrong\u003eR-454B\u003c\/strong\u003e refrigerant, from the new generation, with a much lower global warming potential than the previous one. Classified A2L, it calls for precise installation methods, which we apply on every job.\u003c\/p\u003e\n\u003ch3\u003eWhich space it suits\u003c\/h3\u003e\n\u003cp\u003eA nominal capacity of \u003cstrong\u003e18,000 BTU\/h\u003c\/strong\u003e typically suits a good-sized open kitchen-dining-living area, on the ground floor of a cottage or a townhouse. Replacement is also the opportunity to check that the old size was the right one. If the house has been insulated, if windows have been replaced or if rooms have been opened up since the original installation, the load may have changed: we redo the calculation rather than automatically keeping the same size.\u003c\/p\u003e\n\u003cp\u003eBe wary, too, of comparing nameplates: an old unit with the same nominal capacity did not necessarily deliver the same heat in cold weather. It is the points measured at -8 °C and -15 °C that allow a comparison, and those are what we base our recommendation on.\u003c\/p\u003e\n\u003ch3\u003eWinter, certified figures\u003c\/h3\u003e\n\u003cp\u003eThe certificate lists \u003cstrong\u003e14,000 BTU\/h at -8 °C\u003c\/strong\u003e (17 °F), about 78% of nominal capacity, with a \u003cstrong\u003eCOP of 2.49\u003c\/strong\u003e, and \u003cstrong\u003e11,500 BTU\/h at -15 °C\u003c\/strong\u003e (5 °F), about 64%, with a \u003cstrong\u003eCOP of 1.99\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 open area through the fall, the spring and most winter days, with much better efficiency than baseboards. In deep cold, its capacity drops and the baseboards take over part of the demand. The recommended setting stays simple: the heat pump holds the main set point, the baseboard thermostats are set a few degrees lower, and they only switch on when the heat pump needs help.\u003c\/p\u003e\n\u003ch3\u003eCooling and dehumidification\u003c\/h3\u003e\n\u003cp\u003eIn \u003cstrong\u003ecooling\u003c\/strong\u003e mode, the nominal capacity is \u003cstrong\u003e18,000 BTU\/h\u003c\/strong\u003e. The \u003cstrong\u003e11.5 EER2\u003c\/strong\u003e rating measures efficiency on a hot day, and the SEER2 rating of 20.3 sums up efficiency over the whole season. Compared with an old fixed-speed unit, a variable-speed heat pump dehumidifies better: it runs long at low speed, the indoor coil stays cold and condenses moisture from the air, which drains away. \u003cstrong\u003eDehumidification\u003c\/strong\u003e becomes continuous, and the open area stays comfortable without icy air. At low speed, the indoor fan also turns more gently, which you notice most in the evening, while watching TV or talking at the table.\u003c\/p\u003e\n\u003ch3\u003eThe ratings, explained\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cstrong\u003eSEER2 of 20.3\u003c\/strong\u003e: cooling efficiency over the whole summer.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eEER2 of 11.5\u003c\/strong\u003e: cooling efficiency at the hottest moment.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eHSPF2 of 9.1\u003c\/strong\u003e: heating efficiency over the whole season, the most decisive in Quebec.\u003c\/li\u003e\n\u003cli\u003e\u003cstrong\u003eCOP of 2.49 at -8 °C and 1.99 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 215413221\u003c\/strong\u003e, published by NEEP.\u003c\/p\u003e\n\u003ch3\u003eThe $700 LogisVert grant\u003c\/h3\u003e\n\u003cp\u003eThe system is listed in Hydro-Québec's \u003cstrong\u003eLogisVert\u003c\/strong\u003e program, with \u003cstrong\u003e$700\u003c\/strong\u003e for the owner of an existing home, according to the list in effect on the installation date.

We then remove the indoor unit, the outdoor unit and its stand. When possible, the new wall head reuses the same wall and the same opening, which limits touch-ups. If a new location is better for air circulation, we suggest it and close the old opening neatly.\u003c\/p\u003e\n\u003ch3\u003eLines, stand and outdoor unit\u003c\/h3\u003e\n\u003cp\u003eWe assess the condition and diameter of the existing \u003cstrong\u003erefrigerant lines\u003c\/strong\u003e to decide whether they can be reused or should be replaced; with a new refrigerant, we favour the solution that ensures the circuit stays tight over the long term. The outdoor unit goes on a ground or wall stand, \u003cstrong\u003eabove the snow line\u003c\/strong\u003e, away from bedroom windows, including the neighbours'. It is also a chance to correct an old stand that was too low and buried in snow every winter.\u003c\/p\u003e\n\u003ch3\u003eElectrical and commissioning\u003c\/h3\u003e\n\u003cp\u003eThe system needs a \u003cstrong\u003ededicated circuit\u003c\/strong\u003e. The old unit's circuit can sometimes be used, but we check that the breaker, wiring and disconnect suit the new unit before reusing it. At \u003cstrong\u003ecommissioning\u003c\/strong\u003e, the circuit is evacuated and checked for tightness, then we test heating, cooling and the drain, and set the baseboards as 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.
