When Cold Becomes Unbearable: A Look Back at an Emergency Call in the Heart of Winter
Waiting for a heating repair technician during a Quebec winter is always stressful. But when the temperature drops to -25°C, it can quickly become a nightmare. At AirGreen, we face this kind of situation often, especially during our interventions in the residential neighborhoods of Longueuil. This article recounts a real emergency experienced by one of our clients and how our team responded quickly and efficiently.
A Heating Breakdown on a Freezing Night: The Context
It was early February 2026, in the Vieux-Longueuil sector, when one of our clients called us in a panic: his electric furnace wouldn’t start, and the indoor temperature was dropping fast. The property was a well-insulated single-family home, but the outdoor air, at -25°C, was starting to creep into the bedrooms.
The client had noticed strange behavior the day before: frequent restarts of the central heat pump, a metallic noise, and then silence. The system shut off during the night. When he called us, it was 7:42 a.m., and the indoor temperature had already fallen below 14°C.
AirGreen’s Rapid Response: Emergency Dispatch in Extreme Conditions
In Longueuil, we maintain a dedicated winter emergency team. Upon receiving the call, our technician Marc was immediately dispatched to the site. He arrived before 9 a.m., fully equipped to diagnose and repair a central heat pump—a 3-ton Goodman, R-410A model, installed 8 years earlier.
On-Site Diagnosis: Faulty Control Board
After a full electrical panel test, Marc confirmed power was reaching the unit, but the electronic control board had failed. A power surge may have caused the issue. Fortunately, thanks to our mobile warehouse, Marc had a compatible replacement board on hand.
Installation, reprogramming, start-up sequence checks: everything was done in under two hours. By 11:13 a.m., the house was warming up again. The relieved client told us: “I was starting to worry about my pipes… and my toes!”
The Risks of Waiting Too Long During a Heating Failure
This testimonial highlights how vulnerable homes can be in extreme cold, even when well-insulated. When an electric furnace or central heat pump fails in frigid conditions, the consequences can include:
-
Major damage from frozen and burst water pipes.
-
Extreme discomfort, especially for children and seniors.
-
Spoiled electronics or refrigerated goods.
-
Spike in consumption from backup heaters (portable heaters, oven use, etc.).
