The \u003cstrong\u003eCentral Heat Pump ARCOAIRE H4H5S ION | 5 Tons - 60,000 BTU (Air Handler FJMA4X) - R410A\u003c\/strong\u003e pairs the \u003cstrong\u003eH4H5S60AKAAA\u003c\/strong\u003e outdoor unit with the \u003cstrong\u003eFJMA4X60L0DB\u003c\/strong\u003e indoor unit, an air handler that pushes air through the existing duct system.\u003c\/p\u003e\u003cp\u003eIts ratings are \u003cstrong\u003e14.3 SEER2\u003c\/strong\u003e, \u003cstrong\u003e12.0 EER2\u003c\/strong\u003e and \u003cstrong\u003e7.5 HSPF2\u003c\/strong\u003e. Before getting into the figures, this page starts from the house itself, because it is the house that decides whether a \u003cstrong\u003e5-ton\u003c\/strong\u003e system is the right one.\u003c\/p\u003e\u003ch3\u003eThe house first, the unit second\u003c\/h3\u003e\u003cp\u003eThe size of a central heat pump depends on what the house loses in winter and gains in summer: through the walls, the attic, the windows, air leaks and the sun. Two homes of the same floor area can need very different sizes. That is why we start with a room-by-room load calculation rather than with the size of the old unit.\u003c\/p\u003e\u003cp\u003eIn a very large home, the stakes are real: a five-ton unit installed in a house that needs less runs short cycles, dehumidifies poorly in summer and creates gaps between rooms. A justified size, on the other hand, runs long, steady cycles and keeps the house even.\u003c\/p\u003e\u003ch3\u003eInsulation and airtightness: what can change the size\u003c\/h3\u003e\u003cp\u003eSome work significantly reduces a home's needs: attic insulation, sealing air leaks around windows, doors and the rim joist, replacing old windows. If you are planning such work, tell us before the load calculation. The size must match the house as it will be, not as it was.\u003c\/p\u003e\u003cp\u003eConversely, an enlarged home or a newly finished basement increases the needs. We take these changes into account to recommend the right size, whether it is this one or another.\u003c\/p\u003e\u003ch3\u003eHomes suited to the 5-ton size\u003c\/h3\u003e\u003cp\u003eThis size typically targets very large homes: two spacious levels with a fully finished basement, a very spread-out single-storey home with large glazed areas, or an enlarged home whose duct system serves many rooms. These are typical examples, which only the calculation confirms.\u003c\/p\u003e\u003cp\u003eWhen the calculation lands on the line between two sizes, planned envelope work often tips the balance toward the smaller one. We then present both options, with their consequences for the backup heat and the duct system.\u003c\/p\u003e\u003ch3\u003eWhat the certificate shows\u003c\/h3\u003e\u003cp\u003eThe certificate lists \u003cstrong\u003e36,000 BTU\/h at -8 °C\u003c\/strong\u003e (17 °F) and \u003cstrong\u003e28,400 BTU\/h at -15 °C\u003c\/strong\u003e (5 °F), with a \u003cstrong\u003eCOP of 2.32\u003c\/strong\u003e at the -15 °C point. The two points are measured separately; we report each one as published.\u003c\/p\u003e\u003cp\u003eThese figures come from certificate \u003cstrong\u003eAHRI 210998756\u003c\/strong\u003e, as published in the AHRI certification directory, for the pairing of the \u003cstrong\u003eH4H5S60AKAAA\u003c\/strong\u003e outdoor unit and the \u003cstrong\u003eFJMA4X60L0DB\u003c\/strong\u003e indoor unit. It is this exact pairing that we install.\u003c\/p\u003e\u003ch3\u003eEfficiency, in plain words\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003cstrong\u003eHSPF2 (7.5)\u003c\/strong\u003e: seasonal heating efficiency over a typical winter.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eCOP (2.32 at -15 °C)\u003c\/strong\u003e: the heat delivered divided by the electricity consumed, at that temperature. An electric baseboard has a COP of 1; at this point, the heat pump delivers more than twice the energy it consumes.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eSEER2 (14.3)\u003c\/strong\u003e: seasonal cooling efficiency over a typical summer.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eEER2 (12.0)\u003c\/strong\u003e: cooling efficiency on a hot day, at full demand.\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eThese ratings make it possible to compare systems measured under the same protocols. Actual consumption then depends on the house, its envelope and its setpoints, which is why it pays to look at the envelope at the same time as the unit.\u003c\/p\u003e\u003ch3\u003eWinter and backup heat\u003c\/h3\u003e\u003cp\u003eAt -8 °C, the listed capacity represents about 60% of the 60,000 BTU nominal size; at -15 °C, about 47%. This pairing is a conventional central heat pump; it is not listed as a cold-climate heat pump. The colder it gets, the more heat the house loses and the less heat the heat pump can extract from the air.\u003c\/p\u003e\u003cp\u003eIn deep cold, the air handler's \u003cstrong\u003ebackup heat\u003c\/strong\u003e, or the existing furnace in an installation that keeps it, supplements the heat. An improved envelope delays that moment: the heat pump works alone for longer into the winter. We size the backup heat according to the load calculation and the certificate points.\u003c\/p\u003e\u003ch3\u003eVentilation and air quality\u003c\/h3\u003e\u003cp\u003eA well-sealed home holds its heat better, but it needs controlled ventilation. If the home has an air exchanger, we check its connection to the \u003cstrong\u003educt system\u003c\/strong\u003e during the replacement. The air handler's filter, replaced regularly, traps some of the dust circulating in the house.\u003c\/p\u003e\u003cp\u003eIn winter, indoor air becomes dry, whatever the heating method; a humidifier connected to the duct system can complement the system. We discuss it during the visit if it is a concern in your home.\u003c\/p\u003e\u003ch3\u003eSummer: cooling and dehumidification\u003c\/h3\u003e\u003cp\u003eIn summer, a reversing valve flips the cycle: the indoor coil captures heat from the house and the \u003cstrong\u003eR-410A\u003c\/strong\u003e refrigerant carries it to the outdoor unit. Cool air goes back through the \u003cstrong\u003educts\u003c\/strong\u003e to the upstairs bedrooms; the moisture removed from the air drains through the condensate drain.\u003c\/p\u003e\u003cp\u003eHere again, the envelope matters. A well-insulated attic limits the heat that comes down into the upstairs bedrooms, and closed blinds on large west-facing windows reduce the late-afternoon load. The system then holds a reasonable setpoint without strain, and its long cycles dry the house well.\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. The outdoor unit goes on a stand, above the snow line, on a \u003cstrong\u003ededicated circuit\u003c\/strong\u003e.\u003c\/p\u003e\u003ch3\u003eDucts, electrical and commissioning\u003c\/h3\u003e\u003cp\u003eAt this size, airflow is high: we check the main ducts and the presence of air returns on each level. The heat pump is fed by a \u003cstrong\u003ededicated circuit\u003c\/strong\u003e and the backup heat by its own; the panel's capacity is checked during the visit and any electrical work appears in the quote.\u003c\/p\u003e\u003cul\u003e\u003cli\u003eAir handler installed on the plenum and return, with the planned backup heat.\u003c\/li\u003e\u003cli\u003eOutdoor unit on a stand, above the snow line, away from snow sliding off the roof.\u003c\/li\u003e\u003cli\u003eLine set insulated, evacuated and checked; condensate drain connected to a compliant discharge point.\u003c\/li\u003e\u003cli\u003eCommissioning: charge, temperatures, airflow, balancing, thermostat and an explanation of the settings.\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eMaintenance\u003c\/h3\u003e\u003cp\u003eReplace the system filter according to its format, keep the outdoor unit clear of snow and leaves, and plan annual \u003cstrong\u003eHVAC\u003c\/strong\u003e maintenance of the coil, condensate drain and electrical connections.
