In a family home that already has ducts, that is often where comfort is won or lost: a disconnected duct, a return that is too small or a poorly placed filter is enough to lose part of the efficiency. The \u003cstrong\u003eCentral Heat Pump ARCOAIRE R4H5S Economy | 2.5 Tons - 30,000 BTU (Air Handler FJMA4X) - R410A\u003c\/strong\u003e pairs the \u003cstrong\u003eR4H5S30AKAAA\u003c\/strong\u003e outdoor unit with the \u003cstrong\u003eFJMA4X30L0BB\u003c\/strong\u003e cabinet, which pushes air through that duct system.\u003c\/p\u003e\u003cp\u003eIts certified ratings are \u003cstrong\u003e14.3 SEER2\u003c\/strong\u003e, \u003cstrong\u003e12.0 EER2\u003c\/strong\u003e and \u003cstrong\u003e7.5 HSPF2\u003c\/strong\u003e. The R4H5S series is Arcoaire's Economy series, a conventional pairing to heat and cool the house through its ducts.\u003c\/p\u003e\u003ch3\u003eA family home that already has ducts\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003e2.5-ton\u003c\/strong\u003e size is aimed at good-sized family homes: a two-storey house with a basement, an enlarged bungalow, a detached house from the nineties whose electric furnace and central air conditioner are reaching the end of their life. It handles the cooling of every room served and most of the heating.\u003c\/p\u003e\u003cp\u003eThe size is confirmed with a room-by-room \u003cstrong\u003eload calculation\u003c\/strong\u003e. An older or heavily glazed house may need more; a well-insulated one may do with the size below. We decide during the visit, after seeing the house and its ducts.\u003c\/p\u003e\u003ch3\u003eWhy the ducts matter as much as the equipment\u003c\/h3\u003e\u003cp\u003eAn electric furnace pushes a small amount of very hot air. A heat pump delivers milder air, in larger quantity and for longer. It therefore needs the duct system to let air through freely, on the supply side as on the return. A duct system that is too restrictive makes the blower work harder, reduces the capacity delivered to the rooms and can hurt the system's efficiency.\u003c\/p\u003e\u003cp\u003eLeaks matter too. A duct that runs through a garage, an attic or a crawl space and leaks at its joints heats or cools a space that does not need it. What does not reach the rooms is lost, whatever the equipment's rating.\u003c\/p\u003e\u003ch3\u003eWhat we inspect in the duct system\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003cstrong\u003eMain trunks and branches\u003c\/strong\u003e: size, condition, disconnected or crushed connections.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eJoints\u003c\/strong\u003e: sealing, especially in unheated spaces.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eInsulation\u003c\/strong\u003e of ducts running through a garage, an attic or a crawl space.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eReturn air\u003c\/strong\u003e: number and size of grilles, whether there is a return upstairs.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eFilter rack\u003c\/strong\u003e: format, access and sealing, so that air goes through the filter rather than around it.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eGrilles\u003c\/strong\u003e: closed dampers, grilles blocked by furniture or rugs.\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eA central heat pump only delivers its full efficiency if the airflow keeps up.

The \u003cstrong\u003eFJMA4X30L0BB\u003c\/strong\u003e cabinet is an \u003cstrong\u003eair handler\u003c\/strong\u003e that takes the place of the old electric furnace: it houses the indoor coil, the blower and the \u003cstrong\u003ebackup electric heating elements\u003c\/strong\u003e. The two units are certified together, and we install this pairing as is.\u003c\/p\u003e\u003ch3\u003eHow the heat pump heats and cools\u003c\/h3\u003e\u003cp\u003eWith the \u003cstrong\u003eR-410A\u003c\/strong\u003e refrigerant, the heat pump captures heat from the outdoor air, even cold air, and carries it inside. The compressor concentrates it, the cabinet's coil releases it to the air, and the blower distributes it. In summer, a reversing valve turns the cycle around: the heat of the house is released outdoors and the cold coil removes humidity from the air, which flows out through the condensate drain.\u003c\/p\u003e\u003ch3\u003eWhat the certificate shows\u003c\/h3\u003e\u003cp\u003eThe certificate lists \u003cstrong\u003e17,300 BTU\/h at -8 °C\u003c\/strong\u003e and \u003cstrong\u003e13,200 BTU\/h at -15 °C\u003c\/strong\u003e. The two points are measured separately; we report each one as published. At the -15 °C point, the \u003cstrong\u003eCOP\u003c\/strong\u003e is \u003cstrong\u003e2.08\u003c\/strong\u003e.\u003c\/p\u003e\u003cp\u003eCompared with the nominal size of 30,000 BTU, the listed capacity represents about 58% at -8 °C and 44% at -15 °C. These figures are measured at the equipment; in the house, the heat delivered also depends on the ducts. That is one more reason to inspect them before the installation.\u003c\/p\u003e\u003cp\u003eThese figures come from certificate \u003cstrong\u003eAHRI 210998993\u003c\/strong\u003e, as published in the AHRI certification directory.\u003c\/p\u003e\u003ch3\u003eThe ratings, straight\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eSEER2\u003c\/strong\u003e of \u003cstrong\u003e14.3\u003c\/strong\u003e measures cooling efficiency over a full summer, and the \u003cstrong\u003eEER2\u003c\/strong\u003e of \u003cstrong\u003e12.0\u003c\/strong\u003e, cooling efficiency at full demand in hot weather.

If maximum efficiency or a grant is your priority, we will also show you better-rated pairings of comparable size.\u003c\/p\u003e\u003ch3\u003eIn deep cold: the backup heat\u003c\/h3\u003e\u003cp\u003eAs the cold intensifies, the heat pump supplies less heat while the house asks for more. In deep cold, the cabinet's backup elements take over the missing share, then switch off when the heat pump is enough again. The thermostat, designed for a heat pump with backup, manages this handover.\u003c\/p\u003e\u003cp\u003eWe size the backup from the load calculation and the capacity of the electrical panel. A steady set point helps the heat pump do most of the work.\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.
