Before going into detail, note that an important clarification about its ratings appears below, in the section on the certificate.\u003c\/p\u003e\u003ch3\u003eThe 4-ton size, for which homes\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003e4-ton\u003c\/strong\u003e size typically targets large homes: a two-level home with an open-concept living room and a finished basement, an enlarged split-level, or a very spread-out single-storey home with an office and a family room in the basement. These are typical examples, not rules.\u003c\/p\u003e\u003cp\u003eThe size is confirmed by a room-by-room load calculation. Attic and wall insulation, window area, orientation and envelope airtightness can change the result from one home to the next, even at equal size. If the calculation points to a smaller size, we recommend it: an oversized unit runs short cycles, dehumidifies poorly in summer and wears out faster.\u003c\/p\u003e\u003ch3\u003eWhat the certificate shows\u003c\/h3\u003e\u003cp\u003eThe pairing of the \u003cstrong\u003eHSH448GKA\u003c\/strong\u003e outdoor unit and the \u003cstrong\u003eFJMA4X48L0CB\u003c\/strong\u003e indoor unit carries certificate \u003cstrong\u003eAHRI 210448771\u003c\/strong\u003e, issued under the former test method, which predates SEER2 and HSPF2 ratings. Its ratings are not directly comparable to the SEER2 and HSPF2 ratings of recent units, so we do not mix them with those. We confirm during the visit the ratings that apply to the installed system.\u003c\/p\u003e\u003cp\u003eThat is why this page publishes no efficiency rating for this pairing. We prefer not to place side by side figures that are not measured the same way.\u003c\/p\u003e\u003ch3\u003eWhy old and new ratings do not mix\u003c\/h3\u003e\u003cp\u003eSEER2 and HSPF2 ratings, like the EER2 rating, come from the current test method. The former method and the new one do not test units under the same conditions, particularly regarding the resistance the duct system puts up against airflow. A figure obtained with the former method therefore cannot be read on the same scale as a SEER2 figure.\u003c\/p\u003e\u003cp\u003eComparing two systems with ratings from different methods would lead to wrong conclusions. When you are weighing several pairings, we present you with data that are comparable with each other, on the same basis.\u003c\/p\u003e\u003ch3\u003eWhat we confirm before the quote\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e\u003cstrong\u003eThe size\u003c\/strong\u003e, based on the room-by-room load calculation.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eThe applicable ratings\u003c\/strong\u003e for the system that will actually be installed.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eGrant eligibility\u003c\/strong\u003e, which depends on the exact pairing.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eThe condition of the duct system\u003c\/strong\u003e and air return, and the corrections to plan.\u003c\/li\u003e\u003cli\u003e\u003cstrong\u003eThe electrical panel's capacity\u003c\/strong\u003e for the heat pump and its backup heat.\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eEverything is set out in a written quote. If another pairing of the same size better meets your priorities, we present it to you.\u003c\/p\u003e\u003ch3\u003eHow a central system works\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eHSH448GKA\u003c\/strong\u003e outdoor unit captures heat from the outdoor air in winter and releases the home's heat in summer, thanks to a reversing valve that flips the cycle. The refrigerant is \u003cstrong\u003eR-410A\u003c\/strong\u003e. The \u003cstrong\u003eFJMA4X48L0CB\u003c\/strong\u003e indoor unit takes the place of the old furnace or air handler; it houses the indoor coil, the blower that feeds the whole duct system and the filter.\u003c\/p\u003e\u003cp\u003eBecause it moves heat instead of producing it, the heat pump delivers more energy than it consumes for most of the year. Air reaches the rooms through the existing registers, with no visible equipment. In winter, the outdoor unit periodically runs a defrost cycle of a few minutes; the vapour that rises from it then is normal.\u003c\/p\u003e\u003ch3\u003eHigh ceilings and open areas\u003c\/h3\u003e\u003cp\u003eLarge homes often have a living room with a cathedral ceiling, a mezzanine or a stairwell open over two levels. Warm air rises and collects there: in winter, the lower part of the room stays cool; in summer, the mezzanine becomes the warmest area of the house.\u003c\/p\u003e\u003cp\u003eA well-balanced duct system and the position of the air returns make a big difference. Running the blower continuously, depending on the thermostat setting, mixes the air between top and bottom and reduces those gaps. We look closely at these spaces during the visit, because they often decide how comfortable the whole house feels.\u003c\/p\u003e\u003ch3\u003eWinter: the heat pump first, the backup second\u003c\/h3\u003e\u003cp\u003eThis pairing is a conventional central heat pump; it is not listed as a cold-climate heat pump. Its heating capacity drops as the outdoor temperature falls. In deep cold, the air handler's \u003cstrong\u003ebackup heat\u003c\/strong\u003e, or the existing furnace in an installation that keeps it, takes over.\u003c\/p\u003e\u003cp\u003eIn a home of this size, the backup heat is sized carefully, together with the available electrical capacity. The thermostat always runs the heat pump first.\u003c\/p\u003e\u003ch3\u003eSummer in a large home\u003c\/h3\u003e\u003cp\u003eIn summer, cool air travels through the same \u003cstrong\u003educts\u003c\/strong\u003e as the heat, up to the upstairs bedrooms. The indoor coil removes moisture from the air and the water drains through the condensate drain. The right size, running long cycles, dries the house better than an oversized unit that keeps starting and stopping.\u003c\/p\u003e\u003cp\u003eIn a large home, the upper floor also picks up heat from the roof in the afternoon. Closed blinds on the west side, returns upstairs and a steady setpoint help far more than a very low setpoint set at the end of the day. The system keeps the house comfortable when it can work steadily, rather than catching up on accumulated heat.\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.
