Le Haut-Saint-Laurent RCM: houses and rural properties
In Le Haut-Saint-Laurent RCM, in Montérégie, AirGreen serves 13 municipalities. Most of our work there is in single-family homes, village houses and country properties. On a large lot the outdoor unit is easy to place, but snow, maintenance access and a solid base must be planned. Our teams cover the whole region from our Montréal office, including Godmanchester, Huntingdon, Ormstown and Elgin.
Le Haut-Saint-Laurent RCM by the numbers: the 2021 Census

Many of these houses predate current insulation standards: we check insulation, windows and electrical panel capacity before choosing the capacity.

Where to install the outdoor unit in Le Haut-Saint-Laurent RCM
In Le Haut-Saint-Laurent RCM, where 83% of homes are single-detached houses, the outdoor unit usually sits on a raised ground pad or a wall bracket at the side or back of the house. We keep it above the snow, away from neighbours' windows, and respect the setbacks set by the municipality. Rules change from one town to the next: before installing, check your town's page.
Humid summers, cold winters: choosing the right capacity
In Le Haut-Saint-Laurent RCM, as everywhere in southern Québec, summer brings humid heat waves and winter long stretches below freezing. A correctly sized heat pump dries the air in July without short cycling, and a cold-climate model keeps heating in January. We size it from the floor area, orientation, windows and insulation, never by guesswork.
Repair, maintain, replace
We also repair units we did not install. Cleaning the filters and coils every spring keeps a heat pump efficient and the air healthy. And if a repair would cost more than a replacement, we say so and show you the price before any work starts.
