Installation of a Sharp wall-mounted heat pump in Vimont
Installation of a Sharp wall-mounted heat pump in Vimont, Laval — an AirGreen project combining performance, aesthetics, and lasting comfort for a perfectly air-conditioned basement.
In summer, the outdoor unit rejects the house's heat outside.

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.
Custom-made comfort in a renovated basement
At AirGreen , we recently installed a Sharp wall-mounted heat pump in a residence in the Vimont sector of Laval . This project, carried out in a basement converted into a relaxation area , perfectly illustrates our approach: combining energy efficiency , discreet aesthetics and performance adapted to the real needs of our customers .
A specific space requiring a precise solution
The homeowner wanted to optimize the thermal comfort of his basement, which is often cooler than the rest of the house, while minimizing energy costs. After analyzing the space, we recommended a Sharp heat pump —known for its reliability, low energy consumption, and quiet operation.
The installation was carried out on an interior wall , near a skylight type window , guaranteeing optimal air diffusion and easy access for maintenance.
Technical details of the installation
-
Equipment type: single-zone wall-mounted heat pump
-
Brand: Sharp
-
Model: ZU1 range (R-32, extreme cold)
-
Capacity: 12,000 BTUs, enough to efficiently cool and heat a full basement
-
Condensate evacuation method: gravity, with careful slope to avoid any backflow
-
Electrical installation: dedicated line protected by circuit breaker, complying with current CSA standards
-
Wiring and piping: side routing under discreet white cover, perfectly integrated into the wall finish
We opted for minimal wall drilling to preserve the insulation and integrity of the room. The outdoor unit was installed at the rear of the building, on galvanized wall brackets , ensuring stability and protection against ground moisture.
Aesthetics and integration
The indoor unit blends seamlessly into the decor. Compact and quiet, it blends into the surroundings without disrupting the basement's understated design. Thanks to Sharp technology, air is distributed evenly, ensuring immediate comfort, even on the coldest days.
Result: constant comfort and measurable savings
From the first week, the owner noted:
-
A stable and consistent temperature , summer and winter.
-
A significant reduction in electricity consumption , thanks to Inverter technology.
-
Very low noise level , ideal for a relaxation room or office.
In addition, the Sharp ZU1 heat pump is eligible for provincial subsidies for its energy efficiency (performance greater than −25°C).

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.
