A Critical HVAC Emergency in the Heart of Winter: When Every Minute Matters
In the middle of January in Laval, with temperatures dropping to -20°C, a senior residence with over 80 units faced a total heating system failure, putting the safety of its residents at risk. At AirGreen, we were urgently called in to handle a critical situation where the integrity of the HVAC system and the well-being of elderly occupants were directly threatened. Here’s a detailed account of this complex intervention, carried out with precision, care, and professionalism.
A Critical Alert at 4 a.m.: Initial Diagnosis of the Breakdown
The building’s maintenance manager contacted us in the early morning hours. The existing central heat pump – an aging Goodman model over 10 years old – had completely stopped working. No heat was circulating, not even in emergency backup mode. A remote diagnostic pointed to a failure in the main compressor combined with an electronic control issue.
Fast On-Site Response and Full System Assessment
By 6:15 a.m., our emergency HVAC team was on-site in Laval. Upon inspection, we discovered:
-
A frozen compressor due to poorly managed oil return,
-
A burnt-out control board caused by a power surge and short circuit,
-
Obvious signs of neglected maintenance — the system hadn’t been serviced in over two years.
We immediately deployed temporary electric heaters throughout the building to stabilize indoor temperatures, prioritizing the most vulnerable zones.
Strategic Replacement: Installation of a GOODMAN R-32 | 5 Ton Central Heat Pump
After discussing with the facility manager and securing budget approval, we recommended the urgent installation of a new 5 Ton GOODMAN central heat pump using eco-friendly R-32 refrigerant, fully compliant with today’s environmental standards and eligible for a LogisVert grant of up to $2,940.
Technical specifications of the unit installed:
-
Brand: GOODMAN
-
Capacity: 60,000 BTU (5 Tons)
-
Refrigerant: R-32 (low GWP)
-
SEER: 17.5
-
HSPF: 9.4
-
Technology: Inverter
-
Eligibility: LogisVert Program – Laval – North Shore
Technical Challenges Faced During Installation
-
The original compressor setup was fully customized, requiring a partial redesign of the duct network.
-
The mechanical room was tight, forcing us to temporarily dismantle a wall partition.
-
The electrical supply required an upgrade at the breaker panel (from 60A to 70A).
-
We coordinated same-day work with a master electrician, proving our ability to mobilize trusted partners quickly.
Timeline and Results

Total time required: 15 hours over 2 days
-
Temporary heat provided throughout the process

New system fully operational by 9:00 p.m. the following day
