A neat installation on a modern brick-clad house
At AirGreen , we recently completed a Windair wall-mounted heat pump installation in a contemporary home in the Sainte-Julie area of Montreal's South Shore. This project perfectly illustrates our meticulous approach to residential HVAC installation : performance, aesthetics and durability.
The context: a new, high-energy-efficiency residence
The homeowner had just moved into a new, well-insulated, gray brick home. He wanted an energy-efficient heating and cooling solution to complement his main system while minimizing the exterior visual impact. After analyzing the building's layout, we recommended the Windair 12,000 BTU wall-mounted heat pump , known for its high energy efficiency and quiet operation.
Site preparation: analysis, drilling and wall support
Before any installation, our technicians assessed the wall structure to determine the optimal location for the outdoor compressor. The rear wall, facing north, provided the best ventilation and safe clearance from traffic areas.
We then have:
-
installed a high-strength galvanized wall bracket ;
-
sealed the anchor points with an exterior silicone sealant to ensure watertightness;
-
drilled the refrigeration line passage to the indoor unit, respecting the required drainage angle;
-
fixed a gray aesthetic sheath matching the brick of the building to conceal the refrigeration and electrical pipes.
Windair heat pump installation: precision and rigor
Once the support was ready, we securely positioned the Windair compressor on the anchors. Inside, the wall-mounted unit was installed at a strategic height to ensure even air distribution throughout the main room.
The connections were then made:
-
Refrigeration connection with flaring and tightening to the exact torque using a torque wrench.
-
Complete vacuuming of the circuit to eliminate all humidity and guarantee the purity of the refrigerant.
-
Nitrogen leak test under pressure for 30 minutes.
-
Release of R-32 refrigerant , more ecological and efficient.
-
Electrical check and calibration of the remote control.
Performance testing and final adjustments
Once the system was turned on, our technician measured:
-
a blowing temperature of 10.8°C in air conditioning mode;
-
reduced instantaneous consumption thanks to Windair Inverter technology ;
-
a sound level barely perceptible at three meters.
After 20 minutes of operation, the interior temperature had already dropped by 3°C, demonstrating the effectiveness of the system.
Result: efficiency, aesthetics and lasting comfort
The installation went smoothly, and the client was impressed by the heat pump's discreet placement on the facade. The exterior ducting blends seamlessly into the house's architecture, while the indoor unit ensures consistent comfort, summer and winter.
This type of Windair wall-mounted heat pump is ideal for modern homes in Sainte-Julie, Boucherville, Brossard and Saint-Bruno , where energy efficiency and aesthetics play a key role.
