When Freezing Temperatures Challenge Our HVAC Technicians in Montréal
Every winter, the severe cold that hits Montréal, Laval, Longueuil, and the North Shore and South Shore regions severely tests heating systems. At AirGreen, we've often faced critical situations requiring rapid, efficient, and sometimes even heroic interventions. Today, we share some of our most memorable cases, where technical expertise and quick action saved our clients from disaster.
Emergency Intervention During a Storm: Rescuing a Heat Pump in Laval
It was 11 p.m. on an especially freezing February night when our rapid-response team received an urgent call. A Laval family had completely lost heat due to a sudden breakdown of their Lennox EL18XPV central heat pump, rated at 36,000 BTU—a recent and normally reliable model. The outside temperature was nearing -30°C.
Our technicians arrived in under an hour, fully equipped to tackle extreme conditions. After a quick inspection, they identified the issue: the compressor was blocked by unusual ice accumulation caused by improper drainage during the original installation. We immediately proceeded to thoroughly defrost the compressor and adjusted the drainage pipe's angle to prevent future buildup.
Result: in less than two hours, heat was restored, preventing frozen pipes and ensuring the Laval family a warm night. This situation clearly highlights the critical importance of impeccable HVAC installation performed by local experts who understand Québec’s climate specifics.
Emergency Rescue at a Seniors’ Residence in Montréal
When a seniors' residence located in Montréal’s Saint-Laurent borough called us urgently, the stakes were incredibly high. Their primary heating boiler—a Trane XC95m rated at 120,000 BTU—had abruptly shut down amid an extreme cold snap, leaving vulnerable residents exposed to severe winter conditions.
Our certified technicians rushed to the site, quickly identifying a critical fault in the electronic burner. Rapid and precise intervention was necessary, as the cold posed a serious health risk to elderly residents. Our team urgently replaced the defective components from our always-ready emergency stock.
Within just a few hours, we fully restored the heating system. The speed and effectiveness of this intervention not only prevented an emergency evacuation but ensured continued comfort and safety for residents throughout this critical period.
When a Wall-Mounted Air Conditioner Became Essential in Longueuil, Even During Winter
While wall-mounted air conditioners are typically associated with summer, we experienced a particularly revealing situation in Longueuil that highlighted the importance of a wall-mounted split unit capable of providing supplemental heating. A client with a Fujitsu KETA 24,000 BTU wall-mounted unit urgently contacted us after their main natural gas boiler completely failed.
While awaiting complex boiler repairs, our team reconfigured the wall-mounted unit to temporarily serve as the main heating source. Due to its ability to operate effectively down to -25°C, this temporary yet efficient solution allowed the family to remain comfortably warm during the entire repair period. This precise case clearly demonstrates the often-overlooked advantages of a high-quality wall-mounted air conditioning unit for residents of the South Shore.
Critical Mistakes to Avoid, According to Our Montréal HVAC Experts
Based on extensive field experience, here are common errors our teams frequently encounter during winter interventions:
-
Neglecting annual maintenance: Regular maintenance prevents mid-winter breakdowns, significantly extending the lifespan of HVAC equipment.
-
Underestimating the importance of proper installation: Installation errors such as poorly angled drainage pipes or improper electrical connections can quickly escalate minor issues into major emergencies.
-
Ignoring early warning signs: Unusual noises, gradual loss of efficiency, or sudden increases in energy costs should immediately grab your attention.
