What is included in professional duct cleaning

Professional duct cleaning involves a comprehensive cleaning of your entire HVAC air distribution system, including supply and return ducts, registers, grilles, diffusers, heat exchangers, cooling coils, drip pans, fan motor, and the air handling unit housing.

The process begins with a thorough inspection using cameras to assess the condition of your ductwork and identify problem areas like mold, excessive dust buildup, or debris. Professional technicians then use powerful truck-mounted or portable vacuum systems that create negative pressure throughout the duct system while simultaneously agitating contaminants with specialized brushes, air whips, and compressed air tools. This dual-action approach ensures debris is loosened and immediately captured rather than blown around your home.

All supply and return vents are individually cleaned, and technicians will access your ductwork through the main trunk lines and individual branch ducts where possible. The furnace blower compartment, evaporator coil (if accessible), and other HVAC components are also cleaned as part of a complete service. Many companies also sanitize the system with EPA-approved antimicrobial treatments to address mold, bacteria, and odors.

In Ottawa's climate, professional duct cleaning typically costs $400-$800 for a whole home and should be done every 3-5 years, or sooner if you have pets, recent renovations, or family members with allergies. The process usually takes 3-4 hours and requires access to your furnace area and all vents throughout the home.

Only hire NADCA-certified technicians who follow proper procedures and use appropriate equipment. Beware of extremely low-priced services that may use inadequate equipment or add expensive upsells once they arrive. Quality duct cleaning should improve your indoor air quality and system efficiency when performed correctly.
