Do you know how often your dryer ducts should be cleaned to prevent a fire? It's a question few Quebec families ask themselves, but one that can literally save lives.
In Quebec, the importance of dryer vent maintenance is still little-known. Yet this simple maintenance can save you hundreds of dollars a year, prolong the life of your appliance and, above all, protect your family from the risk of fire.
In this article, we'll explain exactly how often you should clean your ducts depending on your situation, the signs that don't lie, and why it's even more important in our Quebec climate.
Why duct cleaning is essential
Fire safety: an underestimated risk
Here's a sobering statistic: 33% of dryer-related fires are due to lint build-up in the ductwork. Statistics Canada reports approximately 5,000 fires per year caused by clothes dryers.
La charpie, c’est comme de l’amadou – extrêmement inflammable. « J’ai vu des conduits tellement pleins de charpie qu’il suffisait d’une étincelle pour que tout flambe », raconte Mohamed de Ventilation Vortex Air. « Dans un condo à Brossard, on a trouvé tellement de charpie compactée que le propriétaire nous a dit qu’il avait de la chance que sa maison soit encore debout. »
Energy efficiency: your wallet will thank you
When your ducts are clogged, your dryer works 50% harder. Imagine trying to breathe with a mask on - that's exactly what happens to your appliance.
This translates into an increase of 20 to 30% on your electricity bill. With Hydro-Québec rates, a family in Montreal can see its bill rise from 40$ to 100$ per month just because of dirty ducts.

Device lifetime: prolong your investment
A dryer that constantly overheats is like a car that's always running in the red. Eventually, the engine will fail prematurely.
With regular cleaning, you can add 5 to 10 years to the life of your dryer. Fewer costly repairs, less stress and more money in your pocket.
Indoor air quality: breathe easier at home
Moisture build-up in dirty ducts creates the perfect environment for mold and allergens. These spores are then released into the air in your home.
In Montreal, with our urban pollution and winters when we keep our windows closed, indoor air quality becomes even more important. Our 5 certified technicians often see a noticeable improvement in air quality after a good cleaning.
How often should you clean your dryer vent?
General recommendations for your application
The frequency of cleaning depends on your actual use:
Heavy users (5 loads or more per week) :
- Professional cleaning : every 1 to 2 years
- Large families, home daycare, people who do a lot of washing
Average users (3-4 loads per week) :
- Professional cleaning : every 2 to 3 years
- Typical family of 4
Small users (1-2 loads per week) :
- Professional cleaning : every 3 years
- Couples without children, the elderly
These recommendations also vary according to other factors:
- Conduit length : The longer it takes, the faster it clogs up
- Number of elbows Each turn accumulates more lint
- Material : Rigid plastic conduits clog less than flexible ones
Climate and urban factors in Quebec
Our Quebec climate changes things completely.
Wet summers : Our high humidity causes condensation in the ducts. This moisture mixed with lint creates a sticky paste that blocks air even faster.
Severe winters : The contrast between the warm dryer air and the cold outside air creates even more condensation. Frozen lint becomes as hard as concrete.
Urban features : In condos and apartment buildings in Montreal, Laval and most of the Quebec City region, the ducts are often longer and more complex. Omar explains: "We have ducts that are sometimes 25-30 feet long, with 4-5 elbows. These systems have to be cleaned every year.
Warning signs that the duct needs to be cleaned NOW
Your dryer is giving you clear signs that it's suffocating:
Abnormally long drying time :
- Your jeans take 90 minutes instead of 60
- You need 2 cycles to dry a normal load
Odors and excessive heat :
- It smells musty while the dryer is running
- The room becomes as warm as a sauna
- Dryer exterior is hot to the touch
Visual signs :
- Excessive lint around the dryer
- Lint coming out of the external outlet in large quantities
- Outer flap barely opens

Common myths about duct cleaning
Myth: Emptying the lint filter is enough
Truth: The filter may catch 70% of the lint, but the rest continues its journey through the duct.
"It's like thinking that by changing your car's air filter, you've cleaned the whole engine," explains one of our certified technicians. After 2-3 years, there's enough lint in the duct to cause major problems.
Myth: Only heavy users need to clean
Truth: Even 1 or 2 loads a week will block the duct over time.
A Montreal customer called us because her dryer was taking 2 hours to dry a small load. She lived alone and did just 1 load a week. Her vent was still half blocked after 4 years without cleaning.
Myth: Home cleaning is enough
Truth: Canadian Tire kits can help with basic maintenance, but long ducts with multiple bends require professional equipment.
Our rotating brushes and negative-pressure suction system clean sections that are impossible to reach with household tools.
Professional cleaning vs. DIY
Professional methods: the difference Ventilation Vortex Air

Rotary brushes : They rotate at high speed to loosen lint stuck to the walls, even in tight bends.

Cleaning from the outside : We work mainly from outside, which avoids dirtying your home and guarantees maximum efficiency.
Camera inspection : Before and after, we can show you exactly how your pipes look.
DIY limits: when it's not enough
Home maintenance is better than nothing, but it has its limits:
- Limited scope : Home kits just clean the first 6-8 feet
- No pressure : Without a professional vacuum cleaner, you're just moving lint around
- Risk of compacting : Done badly, you can make the problem worse
- Complex pipes : Impossible to reach elbows and vertical sections
For maintenance between professional cleanings, it's okay. But it doesn't replace a real cleaning.
Trends and regulations in 2025
This year, we're seeing major changes in awareness in Quebec.
Rising demand : With electricity costs on the rise and the City of Montreal's fire prevention campaigns, more families understand the importance of this maintenance.
Official recommendations : The Régie du bâtiment du Québec (RBQ) recommends an annual inspection, even though it is not yet mandatory by law.
NADCA standards : The National Air Duct Cleaners Association emphasizes safety and energy efficiency. Our technicians follow these strict standards.
Urban demand : Montreal, Laval, the North Shore and the entire Montérégie region are seeing explosive demand, particularly for condos with more complex ducting.
Our team of 5 INVC-certified technicians is responding to more requests than ever. We helped over 500 families last year.
