Can a well-designed ventilation system actually reduce fire risks in your home? In Longueuil, it’s an increasingly relevant question. At AirGreen, we’ve seen a growing demand for safe and high-performance ventilation solutions, especially in residential areas that are more prone to risk—such as older buildings or homes located near wooded zones.
We want to show you how a well-designed, properly installed, and well-maintained HVAC ventilation system can contribute not only to thermal comfort and air quality, but also to preventing house fires. Through our expertise in residential ventilation in Longueuil, we’ll share concrete facts that link fire safety and mechanical ventilation.
Stagnant air: an underestimated danger in poorly ventilated homes
In many homes across Longueuil, especially those built before the 2000s, we often find inadequate ventilation. This creates environments where stale air accumulates, electrical systems overheat more quickly, and flammable materials like dust or grease in kitchen ducts become serious fire hazards.
A good mechanical ventilation system (HRV/ERV) or a properly sized air exchanger plays a crucial role here. It helps:
-
Reduce excess humidity that deteriorates electrical circuits.
-
Remove flammable contaminants (gases, vapors, fine dust).
-
Maintain stable temperatures to prevent electrical component overheating.
-
Extend the lifespan of HVAC equipment and household appliances.
Real case in Longueuil: preventive installation in an older duplex
Recently, at a client’s duplex in the Saint-Hubert neighborhood, we were called in to revise an old natural ventilation system in a home built in 1967. The building showed several warning signs: dust buildup in the ducts, overheating issues in the mechanical room, and a clogged return air grille.
We recommended and installed a high-efficiency Venmar EVO5 700 HRV air exchanger, paired with fire-retardant filtered vents. This installation allowed for:
-
Continuous air renewal without heat loss.
-
Automatic evacuation of heat and vapors in technical areas.
-
A 37% reduction in measured relative humidity in the laundry room (a critical zone).
-
A noticeable improvement in comfort, with air feeling lighter and less charged with particles.
Certified ventilation systems: your fire safety allies
All systems we recommend at AirGreen are CSA and UL certified, and feature components that withstand high temperatures. The fans we use are equipped with thermally protected sealed motors, significantly reducing the risk of short-circuits or ignition.
Our installations fully comply with the Canadian National Building Code, as well as local requirements from the Longueuil Fire Safety Department (SSIL). These standards mandate:
-
Minimum spacing between ventilation ducts and heat sources.
-
Use of “M0” classified (non-combustible) duct materials.
-
Automatic fire dampers in multi-unit buildings.
Poor installations: real risks
It’s common to come across uninsulated flexible ducts running through attics or garages, sometimes dangerously close to halogen bulbs or hot surfaces. These errors, often found in non-professional installations, greatly increase fire risks.
At AirGreen, every ventilation project in Longueuil starts with a detailed inspection of the existing system, using thermal imaging, airflow measurements, static pressure analysis, and seal testing on all ductwork.
Regular maintenance: a safety essential
A poorly maintained ventilation system becomes a risk factor. Accumulated dust, clogged filters, dirty motors… These are all flammable elements that can act as a trigger.
We recommend HVAC maintenance every 12 to 18 months, including:
-
Duct cleaning with rotary brushes and HEPA vacuuming.
-
Replacement of MERV-rated filters suited to each setup.
-
Inspection of motors and bearings.
-
Testing of thermal sensors and electronic regulation.
