AirGreen’s Secret: How We Saved an Entire Hotel from a Critical Heating Failure in the Middle of the Night in Montréal

An emergency call in the middle of the night in Montréal: how our team acted fast to restore heating in a hotel in distress

In the world of commercial heating, there’s no room for the unexpected—especially when it comes to guest comfort in a hotel in the middle of January. At AirGreen, we understand better than anyone that in commercial environments like hotels, a single incident can lead to major financial losses, bad reviews, or worse, a full evacuation of the building. That’s exactly what we prevented thanks to a fast and expertly handled intervention in a downtown Montréal hotel.

The context of the call: a sudden and total heating system failure

It was 3:12 AM when our emergency service received a call from a manager of a 120-room hotel, reporting a complete breakdown of the central heating system. The outdoor temperature was -21°C, and the first guest complaints had already started arriving at the front desk. The hotel, located in the Ville-Marie district, relied on a central forced-air system, using a Goodman brand air handler, model ARUF61, connected to a high-efficiency outdoor heat pump.

The emergency was clear: restore the system before sunrise, avoid early checkouts, and protect the hotel’s reputation.

Our emergency response protocol: speed, expertise, and efficiency

Upon receiving the call, two certified commercial HVAC technicians were dispatched immediately. They arrived at 3:48 AM and began a thorough inspection of the system. The preliminary diagnosis revealed a critical failure in the indoor blower motor—a core component of the Goodman ARUF61—which was preventing warm air from circulating throughout the building.

Technical issue: real-time blower motor replacement

At AirGreen, we know the technical characteristics and common issues of models like the Goodman ARUF61, especially their ECM-type motors, which are vital to the proper function of variable-speed air handler systems. Fortunately, our parts warehouse located nearby in the Plateau-Mont-Royal district was stocked with a compatible replacement motor. One of our technicians was sent to retrieve it while the other continued with electrical diagnostics and disassembly of the unit.

A custom repair in under 2 hours

The motor replacement took place between 4:35 and 5:50 AM, including realignment of the drive shaft, calibration of the electronic control module, and a restart in test mode. We also took advantage of the system downtime to inspect and clean the coils, which are often overlooked during annual maintenance—this allowed us to restore optimal thermal efficiency.

Immediate results and full return to normal before sunrise

By 6:07 AM, the system was fully operational again. All floors of the hotel were receiving stable and even heating, and the room temperatures reached the desired 21°C in under 20 minutes.

The hotel’s manager, relieved and impressed by our quick response, confirmed that not a single guest had checked out early. Even better, several positive reviews on booking platforms mentioned the quality of the service and comfort, a situation that could have turned into a disaster for their online reputation.
