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.
Optimized winter comfort thanks to a custom installation
At AirGreen , we know that a well-chosen and well-installed HVAC system transforms our customers' daily lives. We recently installed a Sharp Eco Inverter wall-mounted heat pump in a residence in Montreal's Villeray district, where thermal comfort is essential year-round.
In this project, our team integrated the wall unit into a holiday-decorated living room with a Christmas tree and thoughtful lighting, demonstrating that the aesthetic and discreet integration of heating and air conditioning equipment is possible without compromise.
Project context and client needs
The owners were looking to replace an old, inefficient wall-mounted air conditioner with a versatile solution that could provide both efficient heating in the winter and effective cooling in the summer. The Sharp Eco Inverter was the obvious choice, particularly for:
-
Its Inverter technology allows precise modulation of power and a reduction in electricity consumption.
-
Its Plasmacluster Ion function, helping to improve indoor air quality.
-
Its performance is recognized down to negative temperatures, an essential criterion in the Montreal climate.

Set on a stand raised above the snow, with the clearances the manufacturer requires.
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.
