Emergency HVAC response in Laval: complete control in the face of the unexpected
In the field of HVAC in Laval, some situations demand more than just technical know-how: they require flawless responsiveness, meticulous planning, and the ability to make critical decisions in seconds. That’s exactly what we had to do at AirGreen when we received an emergency call just hours before the opening of a major outdoor cultural festival in Laval.
The Context: a central air conditioning system failed
This festival was expected to draw thousands of people to a large municipal park, with performance stages, tents for artists, food trucks, first aid areas, and a central operations tent. One day before opening, the central air conditioning unit serving the main operations tent – which housed audio systems, electrical equipment, and general control operations – completely broke down.
Without adequate cooling, the temperature inside the tent was rising dangerously, threatening not only the safety of the electronic equipment but also the overall coordination of the event. The event organizer, clearly distressed, contacted us urgently for an emergency HVAC intervention in Laval.
Rapid diagnosis and immediate response
Fast deployment of a specialized team
Less than an hour after the call, our mobile emergency team was already on-site. We dispatched two senior technicians specialized in event climate control, accompanied by a project supervisor. The first step was to diagnose the source of the breakdown: the main compressor of an old central system running on R-22 had burned out.
Restarting the unit was impossible without a full replacement or the installation of a temporary backup system.
Solutions deployed by AirGreen
Faced with this critical situation, our team proposed a two-part solution:
-
Installation of a temporary stand-alone system: We installed two portable heat pumps with 24,000 BTU each, running on R-32, connected to a network of flexible ducts to efficiently cool the space.
-
Planning for a permanent replacement after the event: A meeting was scheduled with the City of Laval’s technical team to discuss replacing the unit with a high-efficiency central heat pump (recommended model: Zephyr 3 Ton, R-454B, eligible for the Hydro-Québec LogisVert grant).
Technical details of the installed equipment
-
Type of temporary unit: Portable construction-grade heat pumps (model: Haxxair Q24 | 24,000 BTU | R-32)
-
Installed in under 4 hours, with insulated ducts, 220V wiring, and secure anchoring
-
On-site thermal evaluation of the space to be cooled
-
Post-installation monitoring throughout the festival to ensure continuous operation
The result: a festival saved, a client reassured
Temperature reduced by 12°C in two hours
Thanks to this rapid intervention, the interior temperature dropped from 36°C to 24°C in under two hours. The electronic equipment remained stable, and the festival’s tech teams were able to run their tests without any interruptions.
Client testimonial
