The \u003cstrong\u003eCentral Heat Pump ARCOAIRE Compact Quiet Comfort | 4 Tons - 48,000 BTU\u003c\/strong\u003e in its \u003cstrong\u003eD5FUHA Air Handler\u003c\/strong\u003e version pairs the 4-ton \u003cstrong\u003eD5CUHAH48AAK\u003c\/strong\u003e outdoor unit with the \u003cstrong\u003eD5FUHAH60XAK\u003c\/strong\u003e cabinet, an air handler one size larger than the outdoor unit.

It is \u003cstrong\u003eENERGY STAR\u003c\/strong\u003e certified with the \u003cstrong\u003ecold-climate designation\u003c\/strong\u003e under \u003cstrong\u003eENERGY STAR ID 3560737\u003c\/strong\u003e, its certificate lists capacity down to \u003cstrong\u003e-30 °C\u003c\/strong\u003e, and it qualifies for a \u003cstrong\u003e$4,740 LogisVert grant\u003c\/strong\u003e.

The same D5CUHAH48AAK outdoor unit can be paired with the matching D5FUAA cabinet or, as here, with the larger D5FUHA cabinet. Each pairing has its own ratings.\u003c\/p\u003e\u003cp\u003eAs a general rule, a larger indoor coil offers more heat-exchange surface, which favours efficiency. In return, if the airflow is not adjusted, it may remove slightly less moisture in summer; we set that airflow during commissioning. During the visit, we compare the two pairings based on the space available in the mechanical room, the duct system and the certified ratings of each.\u003c\/p\u003e\u003ch3\u003eFull capacity at -15 °C\u003c\/h3\u003e\u003cp\u003eThe certificate lists \u003cstrong\u003e39,500 BTU\/h at -8 °C\u003c\/strong\u003e (17 °F) with a \u003cstrong\u003eCOP of 2.56\u003c\/strong\u003e, and \u003cstrong\u003e48,000 BTU\/h at -15 °C\u003c\/strong\u003e (5 °F) with a \u003cstrong\u003eCOP of 2.00\u003c\/strong\u003e, which is 100% of the nominal size. The two points are measured separately; we report each one as published. At \u003cstrong\u003e-30 °C\u003c\/strong\u003e, the certificate still lists \u003cstrong\u003e27,200 BTU\/h\u003c\/strong\u003e with a \u003cstrong\u003eCOP of 1.46\u003c\/strong\u003e. These figures come from certificate \u003cstrong\u003eAHRI 215318903\u003c\/strong\u003e, published by NEEP.\u003c\/p\u003e\u003cp\u003eCOP compares the heat delivered with the electricity used. An electric baseboard has a COP of 1; at -15 °C, this system delivers twice as much heat as the electricity it uses, and it stays above a baseboard down to -30 °C. Over the whole heating season, its efficiency is summed up by the \u003cstrong\u003eHSPF2\u003c\/strong\u003e of 9.5, the rating that weighs most on the bill of an electrically heated home.\u003c\/p\u003e\u003ch3\u003eSummer in a large home: 17.5 SEER2 and 12.0 EER2\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eSEER2\u003c\/strong\u003e measures cooling efficiency over a typical summer, and \u003cstrong\u003eEER2\u003c\/strong\u003e at full load, on a very hot day. In a large sun-exposed home, with big windows and an upper floor under the roof, EER2 is often what matters most: it describes the system's behaviour at the very moment it runs at full power. At \u003cstrong\u003e12.0 EER2\u003c\/strong\u003e, this pairing stays efficient during heat waves.\u003c\/p\u003e\u003cp\u003eThe rest of the summer, the \u003cstrong\u003evariable-speed\u003c\/strong\u003e (\u003cstrong\u003einverter\u003c\/strong\u003e) compressor slows down as it approaches the set point and runs for long periods at low speed. Air spends more time over the cold coil and leaves its moisture there. Condensate drains from the cabinet to a floor drain or a pump.\u003c\/p\u003e\u003ch3\u003eLarge single-storey homes and long air runs\u003c\/h3\u003e\u003cp\u003eA large extended bungalow, a single-storey home with a vast finished basement: in these homes, air has to travel long distances before reaching the rooms at the end of the duct system. The registers farthest from the indoor unit often receive less air, and those rooms stay cooler in winter and warmer in summer.\u003c\/p\u003e\u003cp\u003eDuring the visit, we follow the main trunk to the last branches, note crushed or poorly connected ducts and check the air returns. Balancing dampers then let us divide the airflow between nearby and distant rooms.

The size is confirmed by a room-by-room load calculation: a renovated home may need less than the old unit, an older home with large glazed areas more.\u003c\/p\u003e\u003ch3\u003eElectrical and backup heat\u003c\/h3\u003e\u003cp\u003eDuring deep cold, electric backup, usually housed in the cabinet, supplements the heat pump when the house loses more heat than it supplies. For a home of this size, the backup and the outdoor unit together require a sufficient electrical service. We check the service capacity and the space in the panel during the visit, size the backup from the load calculation and state any necessary electrical work in the quote.\u003c\/p\u003e\u003ch3\u003eR-454B refrigerant\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eR-454B\u003c\/strong\u003e is the refrigerant manufacturers have adopted for their new central heat pumps; if it leaks, its effect on global warming is much lower than that of the refrigerant it replaces. It belongs to the A2L class, known as mildly flammable. Its installation follows specific requirements, especially for circuit tightness and indoor unit safety, which our refrigeration technicians apply.\u003c\/p\u003e\u003ch3\u003eThe $4,740 LogisVert grant\u003c\/h3\u003e\u003cp\u003eThe system is listed in Hydro-Québec's \u003cstrong\u003eLogisVert\u003c\/strong\u003e program, with \u003cstrong\u003e$4,740\u003c\/strong\u003e for the owner of an existing home, according to the list in effect on the installation date.

On installation day, the furnace is removed and the D5FUHA cabinet takes its place, connected to the plenum, the air return and the condensate drain.\u003c\/p\u003e\u003cp\u003eThe outdoor unit is mounted on a suitable stand or bracket, \u003cstrong\u003eabove the snow line\u003c\/strong\u003e, with enough clearance all around and away from roof drip. The insulated copper line set is brazed, pressure-tested and put under vacuum. The electrical connection is made on a \u003cstrong\u003ededicated circuit\u003c\/strong\u003e, with an outdoor disconnect.

Annual \u003cstrong\u003eHVAC\u003c\/strong\u003e maintenance cleans the coils and checks the condensate drain, the electrical connections and the backup heat. If rooms at the end of the duct system seem less comfortable from one season to the next, mention it during maintenance: adjusting the dampers is often enough.
