A ruthless Montréal winter demands a heating system that is high-performing, reliable, and tailored to your home
Every winter, Montréal and its surrounding areas — Laval, Longueuil, the South Shore and the North Shore — are hit with freezing, sometimes extreme, temperatures. Record-breaking cold waves are more than just uncomfortable: they can become dangerous if your heating system isn’t up to par. At AirGreen, we understand just how essential a well-installed and properly maintained heating system is to ensure comfort, safety, and energy efficiency in your home or commercial building.
We’ve helped hundreds of families and businesses across Greater Montréal deal with these harsh conditions by offering high-performance, tailor-made heating solutions, installed and maintained by our expert HVAC professionals.
The critical challenges of deep freezes in Montréal
When temperatures drop below -20 °C, heating systems are pushed to their limits. Units that are poorly sized, outdated, or improperly maintained are likely to fail when you need them most. This leads not only to discomfort, but also risks like frozen pipes, humidity issues, and costly emergency repairs or replacements.
These are the moments where our expertise at AirGreen truly stands out. We carry out a comprehensive thermal needs assessment for every building, taking into account square footage, insulation, orientation, and usage, in order to recommend the most reliable and energy-efficient system.
The importance of choosing the right unit — and the right installation
Heating performance doesn’t rely solely on the unit itself, but also on the quality of the HVAC installation. A poorly installed system, even if it’s high-end, may not deliver full power and can be prone to premature breakdowns.
Here are the key criteria we consider for every project:
-
Type of building: single-family home, multiplex, condo, commercial property
-
Heating area: total square footage, ceiling height, number of zones
-
Existing insulation
-
Heating needs based on usage (residential, commercial, mixed-use)
-
Budget and eligibility for grants (like Hydro-Québec’s LogisVert program)
Real-life examples: when AirGreen’s expertise makes all the difference

Full annual inspection
