Your dryer now takes two cycles to dry a normal load. Your clothes are still damp after 60 minutes. You notice a strange, burnt smell when the dryer is running.
These signs are not to be ignored. They indicate that your dryer vent is likely clogged with lint buildup.
In Montreal, approximately 2% of residential fires are directly linked to poorly maintained dryer vents, according to RBQ data published in 2025. That represents more than 150 cases per year in the metropolitan area.
At Vortex Air, we've seen a 15% increase in requests for dryer vent cleaning after winter. People often don't realize there's a problem until the damage is already extensive.
This guide explains exactly when to clean your vent, how to recognize the signs of a blockage, and why this simple maintenance can save you thousands of dollars and protect your family.

Why Cleaning Your Dryer Vent Is Essential in Montreal
Clean the dryer vent It may seem like a minor task compared to maintaining the furnace or ventilation system. But that’s a mistake that can be costly.
Montreal’s climate makes the problem even more critical. Our long, damp winters create the perfect conditions for lint to accumulate and become compacted in the ducts.
The Often Underestimated Risk of Fire
Lint is extremely flammable. It consists mainly of dry, lightweight fabric fibers, sometimes mixed with detergent and fabric softener residues, which are also combustible.
When it builds up in the vent near the dryer’s heating element—which can reach temperatures of 65°C to 75°C—even a slight increase in temperature is enough to start a fire.
The Montreal Fire Department (SIM) reports that these fires are particularly dangerous because they often start inside the walls, where the duct runs. You won't see the flames until it's too late.
The most common myth? «My dryer’s lint filter catches everything.» False. The filter catches only about 25% of the lint produced. The remaining 75% passes through the vent and gradually accumulates there.
The Quebec Building Code, Chapter I, Section 9.33, requires that dryer vents be made of rigid, metallic materials. Old flexible plastic or vinyl ducts have been banned for years precisely because of the fire hazard they pose. Yet they can still be found in hundreds of homes and condos in Montreal.
Other Effects of a Clogged Pipe
Beyond the risk of fire, a clogged vent affects your wallet and your daily comfort.
Your dryer has to work much harder to remove the moist air. Drying time increases by 50% or more. A load that used to take 45 minutes now takes 90 minutes, or even two full cycles.
This is directly reflected on your Hydro-Québec bill. It is estimated that a clogged drain adds between 40$ and 100$ per year to the electricity costs of an average family.
Moisture that isn't properly vented out remains trapped in the laundry room. In Montreal condos, where ventilation is often limited, this leads to mold problems on the walls and around the windows.
The appliance itself wears out prematurely. The motor, heating element, and electronic components are constantly overworked. A dryer that should last 12 to 15 years breaks down after 7 or 8 years.
The Benefits of Regular Career Counseling
The statistics from Oceanick Nettoyage published in 2025 are clear. Regular professional cleaning reduces the risk of fire by 80% and lowers energy consumption by 25%.
Your clothes dry faster and more evenly. You no longer have to run two or three cycles for a single load. The time you save adds up to hours each month.
Investing in cleaning pays for itself quickly. Between energy savings and the extended lifespan of your appliance, you’ll see a return on your investment in less than two years.
Some Montreal homeowners may even be eligible for Rénoclimat grants ranging from 200$ to 500$ when dryer vent cleaning is combined with other ventilation improvements.
Julie, who lives in Ahuntsic with her family of four, contacted us after smelling something burning: «The technician removed nearly three kilos of compacted lint from my vent. He told me I was just a few weeks away from a potential fire. Now my dryer works like new, and my utility bills have gone down. I have the vent cleaned every year now.»

How often should you clean your dryer vent?
This is the question we’re asked most often. The answer depends on several factors: your type of home, the size of your family, and how often you use it.
Here is a simple table to help guide you:
| Type of housing | Recommended frequency | Reason |
| Single-family home (1–2 people) | Every 3–4 years | Moderate use |
| Single-family home (3–5 people) | Every 1–2 years | Heavy-duty use, no more lint |
| Condo or apartment | Every 2-3 years | Ducts that are often longer and more complex |
| Rental building (owner) | Annually | Legal Obligation to Provide Support |
Official and Practical Recommendations
According to data from SolutionCondo published in 2025, most experts recommend cleaning every 2 to 4 years for normal residential use.
But if you have a family of more than four people, pets that shed a lot, or if you do more than seven loads of laundry a week, shorten this interval to 1 or 2 years.
For condos, the situation is unique. The ducts are often much longer because they have to run through several floors before exiting onto the roof. Some ducts in the towers of the downtown Montreal or in Griffintown are more than 15 meters tall.
These long vents accumulate much more lint and are harder to clean. You’ll also need to coordinate with your condo association to gain access to the roof. Bill 16 on condo management now requires preventive maintenance plans, which should include dryer vents.
Clear signs that cleaning is needed
No matter when you last cleaned, certain symptoms indicate that you need to take action now.
The drying time has increased significantly. If a load that used to take 45 minutes now takes 60 minutes or more, that’s a clear warning sign.
Your clothes and your dryer feel unusually hot to the touch after a cycle. Hot air that isn't venting properly is trapped inside the machine.
If you smell something burning—even just a faint odor—while the dryer is running, it’s lint that’s starting to overheat. Don’t take any chances—stop using the dryer and have the vent inspected immediately.
Lint is clearly accumulating around the duct's exterior outlet. Go outside and check the exterior damper. If it's covered in lint or no longer closes properly, the duct is clogged.
The dryer is making unusual noises or vibrating. The motor is working too hard to compensate for the lack of airflow.
Factors Specific to Montreal
Our climate makes certain times of the year more critical for duct maintenance.
Montreal winters cause condensation to form in the ducts. The hot, humid air from the dryer comes into contact with the extreme cold in the uninsulated sections of the ducts. This condensation makes lint sticky and causes it to build up more quickly.
Older buildings in the Plateau, Rosemont, or Ahuntsic often have original pipes dating back to the 1960s or 1970s. They are long, have many bends, and are rarely insulated properly. They require more frequent maintenance.
In contrast, new condos in high-rises such as those in Griffintown or downtown have extremely long ducts that run vertically up several floors. Accessing the roof for cleaning is complicated and often requires coordination with building management.
Is your dryer taking longer to dry clothes? That's often the first sign of a clog! Don't let the situation get worse—contact us for an assessment.
Facts, Myths, and Gray Areas of Duct Cleaning
There’s a lot of information out there about dryer vent maintenance. Let’s separate fact from fiction.
The Most Common Myths in Quebec
Myth #1: «The lint filter catches everything it’s supposed to»
Fact: The filter captures about 25% of lint. The remaining 75% passes through the duct. Cleaning the filter after every load is essential, but it is no substitute for cleaning the duct.
Risk: Gradual buildup over the years leading to a complete blockage and a fire hazard.
Solution: Clean the filter after each use AND have the duct professionally cleaned at the recommended intervals.
Myth #2: «Summer is the best time to clean»
Fact: Winter is actually the most critical time of year in Montreal. Condensation caused by the cold makes lint more compact and harder to remove.
Risk: Damp, compacted lint is even more flammable and clogs the vent more quickly.
Solution: Schedule your cleaning for the fall, before winter, when the ducts are dry and easier to clean.
Myth #3: «I can clean it myself with a brush»
Fact: DIY kits available at hardware stores rarely exceed 50% of the duct's depth. Residential ducts are often 3 to 8 meters long and have several elbows.
Risk: False sense of security. You think you've cleaned everything, but dangerous buildup remains.
Solution: DIY cleaning can serve as light maintenance between professional cleanings, but it is no substitute for a thorough cleaning.
What the Experts Say
Martin Garon of the Corporation des maîtres mécaniciens en tuyauterie du Québec (CMMTQ) is clear: «Owners of buildings more than 10 years old should have all dryer vents inspected annually. It’s a matter of public safety, not just preventive maintenance.»
Éric, a senior technician at Vortex Air with more than 8 years of experience, tells us: «We remove an average of 2 to 4 kilos of lint during a standard residential cleaning. In condos with long ducts, we’ve even removed more than 8 kilos. People are always shocked to see how much there is.»
The RBQ and the CMMTQ regularly emphasize the importance of preventive maintenance, especially since Decree 437-2025, which strengthens safety standards for heat-generating appliances in residential buildings.
How Does a Professional Cleaning Service Work in Montreal?
Understanding the process helps you choose a high-quality service and know what to expect.
Free Initial Inspection
Our technicians always begin with a thorough visual and technical inspection.
First, check the inside of the dryer to inspect the condition of the filter and look for any visible buildup. Then, inspect the vent from the dryer to the outdoor vent.
For hard-to-reach pipes, we use an inspection camera that shows us exactly where the blockages are and how severe they are.
We also perform an airflow test. A clean duct should allow for an airflow of at least 100 liters per second. If the measurement is less than 60 L/s, there is definitely a problem.
You’ll receive a clear report with before-cleaning photos, the estimated percentage of blockage, and our recommendations. No pressure, no obligation. If your duct is relatively clean, we’ll tell you straight up.
Certified rotary suction method
Professional cleaning uses specialized equipment that you don't have at home.
First, we safely disconnect the dryer from the vent. We then access the vent from the exterior outlet using our high-powered vacuum system.
A motorized rotating brush travels the entire length of the duct. It loosens the compacted lint from the walls while the industrial vacuum cleaner simultaneously captures it all.
For very long ducts or those with many bends, we sometimes work from both ends to ensure a thorough cleaning.
Professional equipment removes about 95% of accumulated lint, compared to 40–50% for DIY methods.
Finally, we perform another airflow test to confirm that the duct is completely clear. The airflow should have returned to more than 100 L/s.
Duct Inspection and Recommendations
During the cleaning process, our technicians also inspect the physical condition of the duct.
We'll inspect the material. If you still have an old flexible plastic or vinyl duct, we strongly recommend that you replace it with a rigid metal duct that complies with building codes.
We check for leaks, disconnected sections, sharp bends that promote buildup, and a lack of insulation in sections exposed to the cold.
You'll receive personalized tips for maintenance between cleanings: clean the filter after each use, check the outdoor vent monthly, and monitor the drying time.
We'll also explain when to schedule your next cleaning based on your specific situation.

How much does it cost to have a dryer vent cleaned in Montreal?
Let's be frank about money. You deserve to know exactly how much it costs.
For condos, generally add 100$ to 150$ due to the complexity of access and the length of the ducts. If the duct runs up several floors, the price can reach 500$ to 600$.
This price normally includes the initial inspection, a thorough cleaning using professional equipment, a before-and-after flow test, and a report with photos.
DIY vs. Professional Comparison:
| Criterion | DIY | Professional |
| Cost | 50-80$ (kit + time) | 200-400$ |
| Time required | 2–3 hours | 1–2 hours |
| Effectiveness | 40-50% duct | 95% of the duct |
| Risk of damage | Medium | Very low |
| Problem Detection | Impossible | Included |
| Warranty | None | Yes |
The return on investment is quick. Energy savings alone (a reduction of 25%) amount to 40$ to 100$ per year. Over three years, you’ll have already recouped your investment.
Not to mention the peace of mind that comes from knowing your family is safe and that your home isn’t at risk of catching fire because of a neglected vent.

Maintenance and Prevention Between Cleanings
Regular professional cleaning is essential, but maintenance between cleanings helps maintain effectiveness and safety.
Simple Monthly Checklist:
Clean the lint filter after every use—without exception. Take 10 seconds to remove any visible lint. Once a month, wash the filter in hot, soapy water to remove fabric softener residue that clogs the mesh.
Check the vent’s exterior outlet. Go outside and look at the damper. It should open freely when the dryer is running and close completely when it’s turned off. Remove any visible lint around the opening.
Keep an eye on the drying time. Make a mental note of how long a standard load takes. If it increases by 10 minutes or more, that’s a red flag.
Pay attention to your device. New noises, unusual vibrations, or suspicious odors warrant immediate attention.
Winter Protection in Montreal:
In winter, check to make sure the outdoor damper isn't frozen or blocked by snow. After a storm, clear the snow around the vent opening.
Some homeowners are now installing smart sensors that monitor the temperature and airflow in the ductwork. They send alerts to your phone if something is wrong. These emerging technologies are gaining popularity in Montreal.

FAQ – Dryer Vent Cleaning in Montreal (2025)
How often should you clean your dryer vent?
For an average family (3–4 people), clean the pool every 2 to 3 years. If there are 5 or more people in your household, or if you swim more than 7 times a week, clean the pool annually. Owners of rental properties should have their pools inspected annually for safety and compliance reasons.
What are the signs that it's clogged?
A drying time that increases by 20 minutes or more is the clearest sign. Other indicators include: clothes that are very hot after the cycle, a burning smell, visible lint around the vent, the dryer making unusual noises, and excessive moisture in the laundry room.
What should you do if your dryer smells like something is burning?
Stop using the appliance immediately. Unplug it if possible. Do not run any loads until a professional has inspected the vent. A burning smell indicates that lint is overheating, which can cause a fire.
Does cleaning extend the life of the dryer?
Yes, significantly. A clean vent allows the dryer to operate at its normal efficiency without being overloaded. The motor, heating element, and electronic components last much longer. You can extend the dryer’s useful life by 3 to 5 years.
Are there any grants available for maintenance?
Cleaning alone is generally not eligible for subsidies. However, if you replace an old, non-compliant duct with a modern system combined with other ventilation improvements, you may be eligible for Rénoclimat grants ranging from 200$ to 500$.
Can you clean the duct yourself?
You can perform basic maintenance using kits available at hardware stores. However, these kits rarely reach more than 50% into the duct. For a thorough and safe cleaning, especially in long or complex ducts, it is strongly recommended that you hire a professional.
Which products should you avoid?
Never use chemicals, solvents, or abrasive cleaners in the dryer vent. Pressurized water is also not recommended, as moisture promotes mold growth. Mechanical cleaning using vacuuming and brushing is the appropriate method.
How does a free inspection work?
A technician will come to your home at a time that’s convenient for you. He’ll visually inspect the ductwork, perform an airflow test, and show you the system’s actual condition. You’ll receive a clear report with photos and recommendations. There’s no obligation to have the system cleaned if you’d rather wait.
What are the RBQ regulations?
The Quebec Building Code requires rigid metal ducts (no flexible plastic or vinyl). Decree 437-2025 strengthens safety standards for heat-generating appliances. Owners of rental properties have legal obligations regarding preventive maintenance.
