Dryer Vents: The Common Maintenance Mistake That Causes Fires Every Year in Montréal

Thousands of households in Montréal, Laval, Longueuil, on the North Shore and South Shore use their dryers daily without realizing that one simple maintenance oversight can quickly lead to disaster. At AirGreen, we've seen firsthand that lint buildup in dryer vents is one of the most common — and most preventable — causes of residential fires in the Greater Montréal area.

A Commonly Overlooked Danger: Why Dryer Vents Require Regular Maintenance

Most people think that cleaning the lint filter is enough to keep their appliance running safely. However, over time, fiber residue, dust, and moisture build up inside the dryer’s exhaust ducts. This accumulation slowly clogs the vent, reducing ventilation efficiency… and turning those ducts into a fire trap.

Warning Signs of a Blocked Vent

Here are a few signs that should immediately alert homeowners and building managers:

  • Clothes take longer to dry

  • The dryer becomes abnormally hot

  • Burning smell during or after use

  • Visible lint around the exterior vent outlet

  • The dryer shuts off mid-cycle due to overheating safety systems

All these symptoms point to a potentially blocked exhaust duct, a situation that needs to be addressed quickly to avoid fire hazards.

Real Case Study: Emergency Call in Rosemont – Montréal

Recently, our AirGreen team was contacted by a client living in a duplex in Rosemont, Montréal, who was concerned about her dryer giving off excessive heat. Upon arrival, we conducted a full inspection of the setup. The result: more than 80% of the duct was obstructed by a thick layer of lint mixed with moisture, forming an almost airtight plug.

Our team immediately performed a full mechanical cleaning using motorized rotating brushes and a high-powered vacuum designed for ventilation networks. We also recommended installing a new, safer, and code-compliant exterior backdraft damper.

Results Achieved:

  • Immediate 50% reduction in drying time

  • Complete elimination of overheating risk

  • Stronger fire safety

  • A reassured and satisfied customer

Strict Regulations in Montréal and Its Boroughs

Some cities like Laval or Brossard even require regular inspections of dryer ducts in multi-unit buildings. Property managers and condo boards must demonstrate that annual or biannual maintenance is performed by a specialized company. Non-compliance may expose the building to fines or denied insurance claims in the event of a fire.

Recommended Cleaning Frequency

At AirGreen, we recommend:

  • Every 12 to 18 months for a single-family home

  • Annually for multi-unit buildings

  • Every 6 to 12 months for commercial settings (hair salons, laundromats, hotels…)

A Few Tips to Reduce Risk Between Cleanings

  • Clean the lint filter after every cycle

  • Avoid plastic or vinyl flexible ducts: opt for rigid metal ducts

  • Make sure the exterior vent outlet is not blocked by snow, ice, or debris

  • Have your dryer inspected by a professional if you notice excessive heat or unusual noises
