From the outside, the unit looks like an air conditioner; the difference is that it also works in winter and handles most of the \u003cstrong\u003eheating\u003c\/strong\u003e. The \u003cstrong\u003eCentral Heat Pump ARCOAIRE HSH6 Premium | 3.5 Tons - 42,000 BTU (Air Handler FJMA4X) - R410A\u003c\/strong\u003e pairs the \u003cstrong\u003eHSH642GKA\u003c\/strong\u003e outdoor unit with the \u003cstrong\u003eFJMA4X42L0BB\u003c\/strong\u003e indoor unit, an air handler that pushes air through the existing duct system.\u003c\/p\u003e\u003cp\u003eThis pairing from Arcoaire's Premium range, in the \u003cstrong\u003e3.5-ton\u003c\/strong\u003e size, is offered while supplies last.\u003c\/p\u003e\u003ch3\u003eFrom central air conditioner to central heat pump\u003c\/h3\u003e\u003cp\u003eA central air conditioner captures heat from the house and releases it outdoors, from June to September. A heat pump does the same in summer, but it has a reversing valve that flips the cycle in winter: it then captures the heat contained in the outdoor air and delivers it indoors through the \u003cstrong\u003educts\u003c\/strong\u003e. The refrigerant is \u003cstrong\u003eR-410A\u003c\/strong\u003e.\u003c\/p\u003e\u003cp\u003eThis change of use has concrete consequences. The outdoor unit now runs twelve months a year, under snow and freezing rain, and it must be installed accordingly. The indoor system must also be able to heat, with backup for deep cold. The following sections explain what this changes in your home.\u003c\/p\u003e\u003ch3\u003eThe outdoor location often has to change\u003c\/h3\u003e\u003cp\u003eA central air conditioner is often set on a slab at ground level, sometimes under an eave or near a walkway. That did not matter for a unit that sleeps all winter. A heat pump, however, must stay clear of snow to breathe, and it produces meltwater during its defrost cycles.\u003c\/p\u003e\u003cp\u003eWe therefore install the \u003cstrong\u003eHSH642GKA\u003c\/strong\u003e outdoor unit on a stand, above the snow line, away from snow and ice falling off the roof. We avoid placing it above a walkway or stairs, where defrost water could freeze. The old air conditioner's location is sometimes usable, but not always.\u003c\/p\u003e\u003ch3\u003eThe line set: reuse or replace\u003c\/h3\u003e\u003cp\u003eThe copper line set between the outdoor unit and the indoor unit is a key part of the system. With an old air conditioner, it may have been sized for another unit, used with another refrigerant or have insulation damaged by the sun. We inspect it and decide, case by case, whether it needs to be replaced.\u003c\/p\u003e\u003cp\u003eIn every case, the line set is insulated along its full length, evacuated and checked before the refrigerant is released. It is a step you no longer see once the job is done, but it matters for the life of the compressor.\u003c\/p\u003e\u003ch3\u003eA matched air handler\u003c\/h3\u003e\u003cp\u003eIn many original installations, the air conditioner's coil sits on top of the furnace, and the two units were bought at different times. Here, the \u003cstrong\u003eFJMA4X42L0BB\u003c\/strong\u003e indoor unit combines the coil, the blower and the filter in a single unit, chosen to work with the outdoor unit. It takes the place of the old furnace or air handler and receives the \u003cstrong\u003ebackup heat\u003c\/strong\u003e.\u003c\/p\u003e\u003cp\u003eThis factory pairing avoids improvised combinations and simplifies maintenance: one indoor unit to inspect, one filter to replace.\u003c\/p\u003e\u003ch3\u003eWhy the size may differ from the old air conditioner\u003c\/h3\u003e\u003cp\u003eIn Quebec, a home's heating needs generally exceed its cooling needs. The size of a central heat pump is therefore not copied from the old air conditioner: it is calculated room by room, taking into account the insulation, windows and airtightness of the house.\u003c\/p\u003e\u003cp\u003eThe \u003cstrong\u003e3.5-ton\u003c\/strong\u003e size typically suits a two-level semi-detached home with a finished basement, a split-level home or a mid-sized cottage. The load calculation confirms the size; if another one fits better, we recommend it.\u003c\/p\u003e\u003ch3\u003eWinter and backup heat\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 decreases as the outdoor temperature drops. In deep cold, the air handler's backup heat, or the furnace kept in some installations, takes over.\u003c\/p\u003e\u003cp\u003eThe thermostat runs the heat pump first and only calls on the backup when necessary. We size this backup according to the load calculation and list it in the quote.\u003c\/p\u003e\u003ch3\u003eA heat pump thermostat\u003c\/h3\u003e\u003cp\u003eThe thermostat for an air conditioner and a furnace cannot manage a heat pump. We install a compatible thermostat that controls the outdoor unit in heating and cooling, then the backup heat when the heat pump is no longer enough. Most of these thermostats also offer an emergency heat mode, which uses only the backup.\u003c\/p\u003e\u003cp\u003eThis emergency mode is only for when the outdoor unit is out of service, while you wait for our visit. Left on by mistake, it deprives the house of the heat pump's benefits. We show these settings during commissioning, so everyone in the home knows how to use them.\u003c\/p\u003e\u003ch3\u003eSummer, as before, but better distributed\u003c\/h3\u003e\u003cp\u003eIn summer, the system cools the whole house through the \u003cstrong\u003educts\u003c\/strong\u003e and removes moisture from the air; condensed water drains through the condensate drain. If the upper floor stayed hot with the old air conditioner, the cause is often in the duct system: insufficient air returns, poorly balanced registers, an overly restrictive filter. We check these points before concluding that a bigger unit is needed.\u003c\/p\u003e\u003ch3\u003eSystem ratings\u003c\/h3\u003e\u003cp\u003eThe pairing of the \u003cstrong\u003eHSH642GKA\u003c\/strong\u003e outdoor unit and the \u003cstrong\u003eFJMA4X42L0BB\u003c\/strong\u003e indoor unit is not listed with SEER2 ratings in the AHRI certification directory. We therefore publish no efficiency rating for this pairing. We confirm the ratings of the complete system before the quote; they also determine grant eligibility.\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. If the grant matters for your project, we will point you to an eligible pairing of comparable size.\u003c\/p\u003e\u003ch2\u003eInstallation in a ducted home\u003c\/h2\u003e\u003cp\u003eThe indoor unit takes the place of the old furnace or air handler and connects to the existing \u003cstrong\u003educt system\u003c\/strong\u003e. 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.

Never put a winter cover on the outdoor unit the way people did with an air conditioner: the heat pump needs it uncovered to heat.\u003c\/p\u003e\u003ch3\u003eAirGreen, for the life of the installation\u003c\/h3\u003e\u003cp\u003eA family business active for more than fifteen years in \u003cstrong\u003eMontreal\u003c\/strong\u003e, \u003cstrong\u003eLaval\u003c\/strong\u003e, \u003cstrong\u003eLongueuil\u003c\/strong\u003e, the \u003cstrong\u003eNorth Shore\u003c\/strong\u003e and the \u003cstrong\u003eSouth Shore\u003c\/strong\u003e, we hold RBQ licences for ventilation, refrigeration and electrical work and carry \u003cstrong\u003e$5,000,000\u003c\/strong\u003e in liability insurance.
