The two points are measured separately; we report each one as published, without extrapolating to other temperatures.\u003c\/p\u003e\u003cp\u003eThese figures come from certificate \u003cstrong\u003eAHRI 210998884\u003c\/strong\u003e, as published in the AHRI certification directory.

An electric baseboard has a COP of 1; with a COP of 2.16 at -15 °C, the heat pump still delivers more than twice the energy it consumes at that point.\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eThese ratings are used to compare systems with each other under standardized protocols. Actual consumption then depends on the house, its insulation and the setpoints chosen.\u003c\/p\u003e\u003ch3\u003eWhat the winter figures mean for a 4-ton home\u003c\/h3\u003e\u003cp\u003eAt -8 °C, the listed capacity represents about 60% of the 48,000 BTU nominal size; at -15 °C, about 46%. This is the normal behaviour of a conventional central heat pump: the colder it is outside, the less heat it can extract from the air, while the house needs more. This pairing is not listed as a cold-climate heat pump.\u003c\/p\u003e\u003cp\u003eIn practice, the heat pump covers the home's needs on its own for a large part of the heating season. As the cold intensifies, there comes a point where its capacity is no longer enough: the air handler's \u003cstrong\u003ebackup heat\u003c\/strong\u003e, or the existing furnace in an installation that keeps it, then supplements the heat. The heat pump keeps working; the backup only adds what is missing.\u003c\/p\u003e\u003ch3\u003eBackup heat, a decision as important as the size\u003c\/h3\u003e\u003cp\u003eIn a 4-ton home, the backup heat is not a detail. Its capacity must cover the gap between what the house loses in deep cold and what the heat pump still delivers. We calculate it from the load calculation and the certificate points, then check that the electrical panel can supply it at the same time as the heat pump.\u003c\/p\u003e\u003cp\u003eThe thermostat runs the heat pump first and only calls on the backup when the house needs it. To get the most out of it, avoid large nighttime setbacks in the middle of winter: the morning recovery calls on the backup longer than necessary.\u003c\/p\u003e\u003ch3\u003eHomes suited to the 4-ton size\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003e4-ton\u003c\/strong\u003e size typically suits large homes with ducts: a two-level cottage with a finished basement, a very spread-out single-storey home, or an enlarged home whose duct system serves many rooms. These are typical examples; floor area alone is not enough.\u003c\/p\u003e\u003cp\u003eThe room-by-room load calculation takes into account wall and attic insulation, windows, airtightness and exposure. A large, recent, well-insulated home may need a smaller size; an older home may need this size even if it looks smaller. We recommend the size the calculation justifies.\u003c\/p\u003e\u003ch3\u003eTwo matched units, one system\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eN4H5S48AKAAA\u003c\/strong\u003e outdoor unit houses the compressor, the outdoor coil and the fan. The \u003cstrong\u003eFJMA4X48L0CB\u003c\/strong\u003e indoor unit holds the indoor coil, the blower that feeds the duct system and the filter; it takes the place of the old furnace or air handler. The two are connected by an insulated line set and run on \u003cstrong\u003eR-410A\u003c\/strong\u003e.\u003c\/p\u003e\u003cp\u003eIn winter, the refrigerant captures heat from the outdoor air and releases it into the air of the house; in summer, a reversing valve flips the cycle. The heat pump moves heat instead of producing it, which explains COP values above 1.\u003c\/p\u003e\u003ch3\u003eCooling and dehumidification\u003c\/h3\u003e\u003cp\u003eThe EER2 of \u003cstrong\u003e12.0\u003c\/strong\u003e measures efficiency when it is hot and demand is at its peak, that is, during heat waves, when cooling matters most. In a large home, cool air travels through the same \u003cstrong\u003educts\u003c\/strong\u003e as the heat, up to the upstairs bedrooms.\u003c\/p\u003e\u003cp\u003eThe indoor coil also removes moisture from the air; the water drains through the condensate drain. A properly sized system runs cycles long enough to dry the house, which allows a reasonable summer setpoint without a clammy feeling.\u003c\/p\u003e\u003ch3\u003eLogisVert\u003c\/h3\u003e\u003cp\u003eThis pairing does not carry an amount on Hydro-Québec's \u003cstrong\u003eLogisVert\u003c\/strong\u003e list of October 19, 2026.

Before the quote, we check duct sizes and the air return, because a central heat pump only delivers its full efficiency if the airflow keeps up.

In a real home, that airflow depends on the duct system: undersized ducts or an insufficient air return reduce efficiency and the capacity delivered. At this size, it is often the return that limits.
