A \u003cstrong\u003ecentral heat pump\u003c\/strong\u003e connected to this duct system heats the house through most of the winter and cools it in summer, with a single thermostat. The \u003cstrong\u003eCentral Heat Pump ARCOAIRE H4H7T ION 2 stages | 2 Tons - 24,000 BTU (Air Handler FJMA4X) - R410A\u003c\/strong\u003e pairs the \u003cstrong\u003eH4H7T24AKAAA\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 compressor is \u003cstrong\u003etwo-stage\u003c\/strong\u003e. In a two-level home, where heat rises and the upstairs bedrooms warm up quickly in summer, this feature makes a real difference.\u003c\/p\u003e\u003ch3\u003eA two-level house\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003e2-ton\u003c\/strong\u003e size is aimed at compact two-storey houses, two-level semi-detached houses and townhouses whose ducts serve both floors, when the insulation is reasonable. These homes have one thing in common: warm air rises. In summer, the bedrooms under the roof build up the day's heat; in winter, the main floor and basement are often cooler than upstairs. Baseboards or window air conditioners treat each room separately; a central system moves air between levels and passes it through a filter on every cycle.\u003c\/p\u003e\u003cp\u003eThe size is confirmed with a room-by-room \u003cstrong\u003eload calculation\u003c\/strong\u003e that takes into account roof insulation, bedroom windows and orientation. An older house with a poorly insulated roof may need the next size up; we say so during the visit.\u003c\/p\u003e\u003ch3\u003eThe H4H7T ION pairing and the FJMA4X cabinet\u003c\/h3\u003e\u003cp\u003eThe \u003cstrong\u003eH4H7T24AKAAA\u003c\/strong\u003e outdoor unit holds the two-stage compressor, the outdoor coil and its fan. The \u003cstrong\u003eFJMA4X24L0BC\u003c\/strong\u003e cabinet is an \u003cstrong\u003eair handler\u003c\/strong\u003e: it houses the indoor coil, the blower and the space for 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 linked by an insulated copper refrigerant line and run on \u003cstrong\u003eR-410A\u003c\/strong\u003e. The thermostat must be compatible with a two-stage heat pump and with the backup; we supply it and set it up.\u003c\/p\u003e\u003ch3\u003eA two-stage compressor in a two-level house\u003c\/h3\u003e\u003cp\u003eA single-speed compressor runs at full capacity or stops. A \u003cstrong\u003etwo-stage\u003c\/strong\u003e compressor can also run at a reduced level when demand is moderate, and switch to full capacity when demand rises.\u003c\/p\u003e\u003cp\u003eIn a two-storey house, this matters for a simple reason: how air is shared between levels depends on how long the blower runs. A system that reaches the main-floor set point in a few minutes, then stops, leaves little time for cool air to rise to the bedrooms. A system with a reduced level can run longer without overshooting the set point, and air moves more between levels.\u003c\/p\u003e\u003ch3\u003eSystem ratings\u003c\/h3\u003e\u003cp\u003eThe pairing of the \u003cstrong\u003eH4H7T24AKAAA\u003c\/strong\u003e outdoor unit and the \u003cstrong\u003eFJMA4X24L0BC\u003c\/strong\u003e indoor unit is not listed with SEER2 ratings in the AHRI certification directory. We confirm the ratings of the complete system before the quote; they also determine grant eligibility.\u003c\/p\u003e\u003cp\u003eYou will therefore know the ratings of the proposed system before signing. If you are weighing several options, we compare them on the same basis, with the exact model numbers.\u003c\/p\u003e\u003cp\u003eThese ratings measure three things: cooling efficiency over a season (SEER2), cooling efficiency in hot weather (EER2) and heating efficiency over a season (HSPF2). In Quebec, the last one weighs the most, since the house is heated most of the year.\u003c\/p\u003e\u003ch3\u003eUpstairs, in summer\u003c\/h3\u003e\u003cp\u003eFor the bedrooms to stay comfortable in summer, the equipment is not enough: cool air has to get there and warm air has to be able to leave. During the visit, we check that each bedroom has enough supply, that there is a return upstairs, and that the ducts running up are neither crushed nor disconnected in the walls or attic.\u003c\/p\u003e\u003cp\u003eBalancing dampers then send a little more air upstairs in summer and a little more downstairs in winter. The cabinet cools the air and removes humidity, which flows out through the condensate drain: the bedrooms are cooler and the air drier for the night.\u003c\/p\u003e\u003ch3\u003eHeating, from fall to deep cold\u003c\/h3\u003e\u003cp\u003eA heat pump moves heat instead of producing it. In winter, the refrigerant captures heat from the outdoor air, the compressor concentrates it, and the cabinet's coil releases it to the air that the blower distributes. In mild weather, the heat pump heats the house on its own.\u003c\/p\u003e\u003cp\u003eAs the cold intensifies, it supplies less heat while the house asks for more. In deep cold, the cabinet's backup elements take over the missing share. We size them from the load calculation and the capacity of the electrical panel. During defrost, the white vapour rising from the outdoor unit is normal.\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.
