Heating problem in the middle of winter? At AirGreen, every furnace repair is much more than just a quick fix: it's a strategic intervention to restore thermal comfort for families and businesses across Montréal, Laval, Longueuil, North Shore and South Shore. In this article, we invite you to dive into the behind-the-scenes of a typical service call, where our team demonstrates unmatched professionalism to bring a central heating system back to life.
When urgency strikes: the context of a critical repair in the heart of January
It’s 7:45 AM on a freezing January morning in Saint-Eustache. A client calls us, clearly distressed: her natural gas furnace—a Goodman brand, installed 11 years ago—won’t turn on. The indoor temperature has dropped to 15°C, and the thermostat won’t respond. Without heat, her family is left vulnerable to an extreme cold snap.
Fast deployment of our technical team
At AirGreen, we know that in winter, every minute counts. Less than two hours after the call, our certified technician Frédéric arrives on-site. Specifically trained to diagnose complex HVAC systems, he immediately begins a full inspection of the unit.
Step 1: In-depth diagnostics
The Goodman GMVC96 furnace, a high-efficiency two-stage model, showed severe burner clogging and a flame detection issue. Using our digital diagnostic tools, we confirmed a failure in the flame sensor and the main control board, a common issue after several years of operation without routine maintenance.
Step 2: Clear explanation and transparency
Frédéric takes the time to calmly explain the root cause to the client, the available options, and which parts need replacement. Our approach is based on full transparency: no surprises, no hidden fees. The quote is immediately approved, as the client feels she is in good hands.
Parts replacement and precision calibration
We replaced the flame sensor and control board from our mobile inventory. Every part installed by AirGreen is OEM certified and comes with a warranty.
Frédéric then proceeds with a complete gas flow calibration, checks the chimney draft, and runs a combustion gas analysis to ensure optimal performance. The result: the furnace restarts, warmth is restored throughout the house… and the client can finally relax.
Our preventive maintenance practices: the art of avoiding breakdowns
During every repair, we offer personalized advice to prevent future failures. In this case, we recommended an annual HVAC maintenance that includes:
-
Cleaning of the heat exchangers
-
Electrical connection check
-
Air temperature output control
-
Thermostat and sensor testing
We also enrolled this client in our AirGreen preventive maintenance program, which includes an annual service reminder, preferential rates on parts, and emergency service priority.
