Cornwall Air Duct Cleaning

For more than 60 years, National Duct has been a trusted leader in professional air duct cleaning and dryer duct cleaning across Ontario. Now serving Cornwall and surrounding areas, we deliver high-quality service to homes and businesses looking to improve air quality, HVAC efficiency, and indoor comfort. Whether you’re living in a riverside home in Downtown Cornwall, a quiet family property in Eamer’s Corners, or managing a commercial site near Boundary Road, National Duct is your local go-to for clean, breathable air.

Cornwall’s mix of historical homes, new developments, and changing weather patterns makes routine duct maintenance essential. As your HVAC system heats and cools your property throughout the year, dust, allergens, mold spores, lint, and other debris accumulate in your ductwork and dryer vent. These pollutants recirculate through your home with every cycle of the system—affecting indoor air quality, aggravating allergies, and reducing system efficiency.

Our experienced technicians provide deep, professional duct and vent cleaning using proven methods. We’re here to help Cornwall residents take control of their indoor air—safely, efficiently, and without disruption.

Why Clean Your Ducts in Cornwall?

Ducts and dryer vents are out of sight—but the impact of what’s inside them is felt in every room. When air circulates through a dirty system, contaminants get pushed into your living or work space. This can result in poor air quality, dusty surfaces, stale smells, or uneven heating and cooling.

Cornwall’s older buildings, seasonal humidity, and indoor lifestyle patterns all contribute to duct buildup. The solution? A professional, whole-system clean that clears away years of unseen buildup.

Benefits of Air Duct and Dryer Vent Cleaning:

• Healthier air quality – Reduces allergens, dust mites, and mold spores

• Increased HVAC efficiency – Allows for smoother airflow and better temperature control

• Lower energy costs – A cleaner system doesn’t have to work as hard

• Less dust indoors – Surfaces stay cleaner for longer

• Odor removal – Musty or smoky smells are eliminated at the source

• Improved dryer performance – Faster drying times and lower fire risk

• Extended appliance life – Reduce wear and tear on HVAC and dryer units

• Peace of mind – Breathe easier knowing your system is clean and safe

This is not just a cleaning service—it’s an investment in your family’s health and your home’s performance.

When to Schedule a Cleaning

Many Cornwall homeowners wait too long before scheduling their first duct cleaning. While most systems benefit from a cleaning every 3–5 years, homes with pets, allergies, renovations, or frequent HVAC use may require more frequent service. Dryer vents, especially, should be cleaned at least once per year.

Signs It’s Time to Call National Duct:

• You see or smell dust coming from vents

• The air in your home feels stuffy or musty

• Allergy symptoms worsen indoors

• Your system is noisy or seems to run constantly

• Dryer takes more than one cycle to dry clothes

• You’ve recently renovated or moved into a new home

• It’s been years—or never—since your last duct cleaning

We clean all types of properties:

• Bungalows and two-storey homes

• Condos and townhouses

• Apartments and rental units

• Commercial offices and retail shops

• Clinics, studios, and daycares

• Industrial buildings and small businesses

Every visit includes careful inspection, full system cleaning, and a complete cleanup.
