An installation by AirGreen: expertise, transparency and trust

Concrete example: Residential installation in Longueuil

In the spring of 2025, our team installed a Zephyr DoubleZone 24,000 BTU in an intergenerational home in Longueuil , with a 12,000 + 12,000 BTU configuration. The main living room and the basement bedroom had very different needs: lots of glazing on the main floor, and very little insulation in the basement. Result? A custom solution, a client eligible for the $2,112 grant , and a 40% reduction on their annual heating bill . All with a zero initial deposit , as per our policy.

Installation on the North Shore: discretion and comfort

Another installation in Blainville demonstrated the versatility of this system. The client was looking for a quiet heat pump for their single-story home. Thanks to our rapid response, the unit was installed in one day, without drilling into any supporting structure. The system's virtually inaudible appearance, both indoors and outdoors, won over the entire family.
