A \u003cstrong\u003ecentral heat pump\u003c\/strong\u003e connected to the existing \u003cstrong\u003educts\u003c\/strong\u003e heats and cools this large volume along with the bedrooms, with a single thermostat. The \u003cstrong\u003eCentral Heat Pump ARCOAIRE N4H5S Performance | 2.5 Tons - 30,000 BTU (Air Handler FJMA4X) - R410A\u003c\/strong\u003e pairs the \u003cstrong\u003eN4H5S30AKAAA\u003c\/strong\u003e outdoor unit with the \u003cstrong\u003eFJMA4X30L0BB\u003c\/strong\u003e cabinet, which pushes air through the 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.\u003c\/p\u003e\u003ch3\u003eFor a mid-size to large home\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003e2.5-ton\u003c\/strong\u003e size is meant for roomier homes that already have ducts: an enlarged bungalow, a two-storey house with an open-concept main floor, a two-level house from the two-thousands, a wide semi-detached house with a finished basement. It handles the cooling of every room served and most of the heating.\u003c\/p\u003e\u003cp\u003eThe exact size is confirmed with a room-by-room \u003cstrong\u003eload calculation\u003c\/strong\u003e. In an open-concept home, glazing weighs heavily: a large west-facing window can call for more cooling than a whole bedroom. Conversely, a recent, well-insulated home may do with the size below. We decide during the visit, with the numbers in hand.\u003c\/p\u003e\u003ch3\u003eThe open-concept area, an air distribution challenge\u003c\/h3\u003e\u003cp\u003eOne large open room is not heated or cooled like three small ones. The volume is larger, heat from the sun and cooking builds up there at the end of the day, and air tends to stratify under a high ceiling. For the room to be comfortable everywhere, air must arrive in sufficient quantity, in the right places, and be able to leave.\u003c\/p\u003e\u003cul\u003e\u003cli\u003e\u003cstrong\u003eSupplies\u003c\/strong\u003e are ideally placed under windows, where cold air sinks in winter and the sun heats in summer.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eReturn air\u003c\/strong\u003e must be large enough for the room's volume; a single return that is too small limits the whole system.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eContinuous fan\u003c\/strong\u003e, set at the thermostat, mixes the air under a high ceiling and reduces the differences between floor and ceiling.\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eThe N4H5S pairing and the FJMA4X cabinet\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eN4H5S30AKAAA\u003c\/strong\u003e outdoor unit holds the compressor, the outdoor coil and its fan. The \u003cstrong\u003eFJMA4X30L0BB\u003c\/strong\u003e cabinet is an \u003cstrong\u003eair handler\u003c\/strong\u003e: it houses the indoor coil, the blower that pushes air through the ducts and the \u003cstrong\u003ebackup electric heating elements\u003c\/strong\u003e. It takes the place of the old electric furnace and connects to the existing plenum and return air.\u003c\/p\u003e\u003cp\u003eThe two units are certified together and linked by an insulated copper refrigerant line. We install this pairing as is, since it is these two units, together, that carry the published ratings.\u003c\/p\u003e\u003ch3\u003eThe heat pump principle\u003c\/h3\u003e\u003cp\u003eA heat pump moves heat instead of producing it. In winter, the \u003cstrong\u003eR-410A\u003c\/strong\u003e refrigerant captures heat from the outdoor air, the compressor concentrates it and the cabinet's coil releases it to the air of the house. In summer, a reversing valve turns the cycle around and the heat of the house is released outdoors. This transfer is what lets the heat pump deliver more energy than it uses.\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 (17 °F) and \u003cstrong\u003e13,200 BTU\/h at -15 °C\u003c\/strong\u003e (5 °F), with a \u003cstrong\u003eCOP of 2.08\u003c\/strong\u003e at -15 °C. The two points are measured separately; we report each one as published.\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. The heat pump therefore keeps heating as the cold sets in, at about twice the efficiency of an electric furnace at the -15 °C point, but a growing share of the heat must come from the backup in deep cold.\u003c\/p\u003e\u003cp\u003eThese figures come from certificate \u003cstrong\u003eAHRI 210998812\u003c\/strong\u003e, as published in the AHRI certification directory.\u003c\/p\u003e\u003ch3\u003eThe backup heat and the electrical panel\u003c\/h3\u003e\u003cp\u003eThe larger the house, the larger the backup must be. The cabinet's heating elements take over when the heat pump is no longer enough, and they are the system's largest electrical load. Their capacity is chosen from the load calculation, but also from what the electrical service and panel can deliver, given the home's other appliances.\u003c\/p\u003e\u003cp\u003eWe check these points during the visit. If the panel needs a change, it appears in the written quote, before signing. The thermostat, designed for a heat pump with backup, then makes the heat pump work first and only calls on the backup when needed.\u003c\/p\u003e\u003ch3\u003eThe ratings explained\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003cstrong\u003eSEER2 (14.3)\u003c\/strong\u003e: seasonal cooling efficiency.

The cabinet cools the air and removes humidity, which flows out through the condensate drain. Blinds or curtains closed during the hot hours help the cooling a great deal, whatever the equipment.\u003c\/p\u003e\u003cp\u003eA properly sized system runs in cycles long enough to remove humidity, which makes the air more comfortable at the same temperature.
