Mounted level on a wall plate, high enough for the air to reach the whole room, with enough space around it to slide the filters out easily.
The refrigerant lines, the communication cable and the drain go through the wall in a single opening, sealed against water, cold air and insects.
Two insulated copper pipes connect the two units. Outside, a line cover can protect them from sun, knocks and weather.
A shut-off switch near the outdoor unit isolates it safely for service. It must stay accessible at all times.
The compressor and the fan. In heating mode it captures heat from the outdoor air, even in winter, and moves it inside.
On the ground or on the wall, it keeps the unit above accumulated snow. The unit stays clear and defrost water can drain away.
The fan needs to blow freely. Storage, a fence or a wall too close, and efficiency drops while noise goes up.
A discreet and efficient HVAC installation on the rear facade
At AirGreen , we recently installed a Sharp Eco Inverter wall-mounted heat pump in the Villeray–Saint-Michel–Parc-Extension neighborhood. This installation demonstrates our expertise in typical Montreal residential configurations, where outdoor space is limited and every installation detail must be optimized.
Project background
The owner of a duplex wanted to improve the thermal comfort of his home while reducing his energy costs. The challenge was to find a compact and efficient solution capable of meeting heating needs in winter and air conditioning in summer, all without altering the aesthetics of the rear facade.

Connected, insulated and protected. The opening is then sealed against water, cold air and insects.
A dedicated circuit and an accessible disconnect near the outdoor unit.
Leak test, vacuum, then start-up and a check of heating and cooling.

And at your place?
Two quick checks with real numbers: what heat costs, and what your current heaters add up to in BTU/h.
Conversion: 1 W = 3.412 BTU/h. An indication, not a load calculation: baseboards and furnaces are often stronger than the real need, and they can stay as backup. AirGreen confirms the capacity on site.
