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 Seamless Integration: When Craftsmanship Meets Innovation
The Challenge: A Unique Installation
Every installation comes with its own set of challenges, and our recent project in Brossard, South Shore was no exception. The task? Installing a Tosot Lomo 23 Wall-Mounted Heat Pump on the second floor, right next to a bathroom, while ensuring the compressor found its home in the backyard. The complexity? Making sure the pipes and electrical wire navigated through another room without a trace.
But challenges are what we at AirGreen thrive on. Our team, with their unmatched expertise, found an ingenious solution. We utilized the walls and ceiling to conceal the pipes, ensuring a seamless and aesthetic finish. The result? A heat pump that seemed to have magically appeared, perfectly integrated into the home's design.

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.
