Duct Cleaning and Air Quality

Providing industry-leading duct cleaning services and air quality products in the Clarence-Rockland, Hawkesbury and Embrun area since 1976

At Fernand Denis, we have three duct cleaning teams ready to serve you. Duct cleaning is important to maintain good indoor air quality and to reduce the amount of regular cleaning you have to do. It also helps your furnace run more efficiently. Over time, your ducts attract dust, allergens, debris and other pollutants. For optimal health and performance, you should clean your ducts every 3-5 years.

For most of our duct cleaning services, we use Rotobrush® to ensure outstanding results. Rotobrush is more than a super powerful vacuum cleaner. It has a brush attached that in combination with the suction can remove the heaviest build-up within duct systems, for a better more thorough cleaning.
