When both are ready, it handles the cooling of every room and most of the heating. The \u003cstrong\u003eCentral Heat Pump ARCOAIRE R4H5S Economy | 2 Tons - 24,000 BTU (Air Handler FJMA4X) - R410A\u003c\/strong\u003e pairs the \u003cstrong\u003eR4H5S24AKAAA\u003c\/strong\u003e outdoor unit with the \u003cstrong\u003eFJMA4X24L0BC\u003c\/strong\u003e cabinet, which pushes air through the existing duct system.\u003c\/p\u003e\u003cp\u003eIts certified ratings are \u003cstrong\u003e15.2 SEER2\u003c\/strong\u003e, \u003cstrong\u003e12.5 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\u003eFor a semi-detached house, a single-storey home or a small two-storey house\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003e2-ton\u003c\/strong\u003e size is aimed at mid-size homes that already have ducts: a two-level semi-detached house, a single-storey home with a partly finished basement, a small two-storey house with a renovated envelope. In these homes, it covers the cooling of every room and a large part of the year's heating needs.\u003c\/p\u003e\u003cp\u003eFloor area alone does not tell the whole story. A semi-detached house has a shared wall that loses little heat; a detached house loses heat on all four sides. Windows, attic insulation and orientation matter too. The room-by-room \u003cstrong\u003eload calculation\u003c\/strong\u003e we do during the visit decides between this size and its neighbours.\u003c\/p\u003e\u003ch3\u003eTwo units, one system\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eR4H5S24AKAAA\u003c\/strong\u003e outdoor unit holds the compressor, the outdoor coil and its fan. The \u003cstrong\u003eFJMA4X24L0BC\u003c\/strong\u003e cabinet, an \u003cstrong\u003eair handler\u003c\/strong\u003e, takes the place of the old electric furnace: it houses the indoor coil, the blower that pushes air through the ducts and the \u003cstrong\u003ebackup electric heating elements\u003c\/strong\u003e. An insulated copper refrigerant line and the control wiring link the two.\u003c\/p\u003e\u003cp\u003eThe two units are certified together; it is this exact pairing that carries the published ratings. We install it as is, without substitution.\u003c\/p\u003e\u003ch3\u003eThe electrical panel, a starting check\u003c\/h3\u003e\u003cp\u003eA central heat pump needs two power supplies: a \u003cstrong\u003ededicated circuit\u003c\/strong\u003e for the outdoor unit, with a disconnect within reach, and the supply to the cabinet, which includes the blower and the backup elements. Those elements are the largest electrical load in the system; their capacity must be chosen according to the heating needs, but also according to what the panel can deliver.\u003c\/p\u003e\u003cp\u003eDuring the visit, we look at the capacity of the electrical service, the free space in the panel and the loads already present: water heater, range, dryer, spa or charging station. A home that has added several of these since its furnace was installed sometimes needs its circuits redistributed. We hold the RBQ licence for electrical work, and everything required appears in the written quote.\u003c\/p\u003e\u003ch3\u003eHeating by capturing heat from the air\u003c\/h3\u003e\u003cp\u003eEven in cold weather, outdoor air contains heat. The heat pump captures it in its outdoor coil with the \u003cstrong\u003eR-410A\u003c\/strong\u003e refrigerant, concentrates it in the compressor and releases it in the cabinet's coil. The blower then sends it through the ducts. In summer, a reversing valve runs the path the other way: the heat of the house is released outdoors.\u003c\/p\u003e\u003cp\u003eThis principle explains why a heat pump uses less electricity than an electric furnace for the same heat. It also explains why its capacity drops as the cold intensifies: there is less heat to capture in the air.\u003c\/p\u003e\u003ch3\u003eThe published winter figures\u003c\/h3\u003e\u003cp\u003eThe certificate lists \u003cstrong\u003e14,200 BTU\/h at -8 °C\u003c\/strong\u003e and \u003cstrong\u003e11,000 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\u003e2.06\u003c\/strong\u003e.\u003c\/p\u003e\u003cp\u003eCompared with the nominal size of 24,000 BTU, these figures come to about 59% at -8 °C and 46% at -15 °C. In other words, on a -15 °C night, the heat pump supplies a little less than half of its nominal capacity, at an efficiency still about twice that of a baseboard.\u003c\/p\u003e\u003cp\u003eThese figures come from certificate \u003cstrong\u003eAHRI 210998675\u003c\/strong\u003e, as published in the AHRI certification directory.\u003c\/p\u003e\u003ch3\u003eWhen the backup heat comes in\u003c\/h3\u003e\u003cp\u003eBeyond a certain level of cold, the house asks for more heat than the heat pump supplies. The cabinet's backup elements then fill the gap, and switch off as soon as the heat pump is enough again. The thermostat, designed for a heat pump with backup, manages this handover with nothing for you to do.\u003c\/p\u003e\u003cp\u003eSizing the backup is a balance. Too small, it leaves the house cool in deep cold; too large, it asks more of the panel than necessary. We set it from the load calculation and the available electrical capacity, and explain it in the quote.\u003c\/p\u003e\u003ch3\u003eSEER2, EER2, HSPF2 and COP, without jargon\u003c\/h3\u003e\u003cp\u003eRead these ratings as an efficiency: the higher the number, the less the system uses for the same work. \u003cstrong\u003eSEER2\u003c\/strong\u003e (\u003cstrong\u003e15.2\u003c\/strong\u003e) applies to cooling over a whole summer. \u003cstrong\u003eEER2\u003c\/strong\u003e (\u003cstrong\u003e12.5\u003c\/strong\u003e) applies to cooling on a heat-wave day. \u003cstrong\u003eHSPF2\u003c\/strong\u003e (\u003cstrong\u003e7.5\u003c\/strong\u003e) applies to heating over a whole season, and it is the one that matters most in a Quebec home.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCOP\u003c\/strong\u003e is read at a specific temperature: it shows how many units of heat the heat pump delivers for each unit of electricity. An electric baseboard is at 1; this pairing is at 2.06 at the -15 °C point.\u003c\/p\u003e\u003ch3\u003eSummer: cooling and humidity\u003c\/h3\u003e\u003cp\u003eIn summer, the same cabinet cools the air and removes humidity, which flows out through the condensate drain. Every room served by the ducts is cooled, with no window unit or wall unit in the bedrooms. The only visible equipment is the outdoor unit, which we place away from bedroom windows as far as possible, yours and your neighbour's.\u003c\/p\u003e\u003cp\u003eA properly sized unit runs long enough to dry the air: the house feels cool without lowering the set point, and the humidity of heavy July days does not settle in.\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.
