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.

Key steps in setting up in Duvernay
Preparation and strategic location
The outdoor condenser was mounted on a raised metal support, protecting the unit from snow accumulation and ensuring optimal ventilation. The installation on the side of the house provided perfect accessibility for the electrical and refrigerant connections.
Commissioning and calibration
Our technicians used a digital manifold to monitor pressure and a vacuum pump to remove moisture from the refrigerant lines before charging the system. This step is crucial to ensure compressor longevity and prevent any issues related to internal contamination.

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.
