Our Air Duct Cleaning Method in Longueuil: The Best Technique on the Market
We clean your ventilation ducts using the push, suction and friction process. This technique is the most effective way to achieve optimal results. Our high-powered truck-mounted units allow us to perform this highly efficient method. Our technician first cleans the furnace and its components, including the coil and filter. Next, he thoroughly cleans the return ducts and air outlets to ensure the entire system is cleaned.
Once the cleaning is complete, an antibacterial treatment is applied by fogging into all ducts. This treatment is included in the cleaning price. A well-maintained system and clean ducts give you better air quality every day. Your system will also run at peak performance, and as a bonus, you’ll lower your electricity costs. We recommend having your air ducts cleaned at least every 5 years or after renovation work.
We also use some of the most powerful equipment on the market to deliver efficient, thorough and professional ducts cleaning in Longueuil. Our process ensures that all dirt, dust and bacteria are removed from your air ducts. With Nettoyeur de la Cité, you can count on quality work!
When Should You Have Your Ducts Cleaned?
- Several signs indicate that your air ducts need cleaning:
- Dust builds up quickly on your furniture, even shortly after cleaning.
- Family members suffer from allergies, asthma or irritation more often at home.
- A musty or dusty smell comes out when the system starts up.
- Airflow seems weak in some rooms.
- Your electricity bill goes up for no apparent reason.
- You’ve just finished renovations (sanding, drywall, demolition).
- You’ve just bought a house and don’t know when the ducts were last cleaned.
In Longueuil, many homes were built between the 1950s and 1970s, particularly in Saint-Hubert and Greenfield Park. Decades of dust and debris can build up in their ducts. A complete cleaning restores your system to its original efficiency.

Double-Checking Your Satisfaction
We issue a cleaning certificate once the work is complete — a real asset when selling your home. At the end of the job, our technician shows you the results to make sure you’re fully satisfied. He then contacts our office for a second check, confirming with you that the work fully meets your expectations. That’s our double satisfaction check, so you get superior-quality work.

Frequently Asked Questions About Ducts Cleaning in Longueuil
How long does ventilation duct cleaning take?
For a single-family home, expect roughly 2 to 4 hours, depending on the size of the system and the number of air outlets.
How often should air ducts be cleaned?
We recommend cleaning at least every 5 years. It’s also a good idea after renovations, after buying a home, or more often if you have pets or family members with allergies.
Do I need to be home during the cleaning?
Yes, an adult must be on site to provide access to the house and the furnace. They must also be present at the end to review the work with the technician.
How should I prepare my home before the cleaning?
Clear access to the furnace and make sure the vent grilles aren’t blocked by furniture. The truck also needs to be able to park close to the house.
Does duct cleaning make a mess?
No. Our truck-mounted unit places the system under negative pressure, so dust is drawn directly outside instead of spreading through your home. All access panels, air inlets and outlets are also carefully sealed to prevent any dust from circulating in the air during the work.
Do you also clean air exchangers and dryer vents?
Yes. We offer air exchanger cleaning and dryer vent cleaning in Longueuil. These services can be combined with your ducts cleaning during the same visit.
