London Air Duct Cleaning

For over 60 years, PowNat—a trusted collaboration between National Duct and Power Vac—has delivered expert air duct cleaning and dryer duct cleaning services to residential and commercial clients throughout London, Ontario. Our team is proud to help improve indoor air quality, reduce allergens, and increase energy efficiency in homes and businesses across the Forest City.

London’s seasonal temperature swings and older housing stock make it especially vulnerable to duct contamination. Pollen in the spring, moisture in the summer, and sealed windows in winter all contribute to poor indoor air quality. Add dust, pet dander, renovation debris, and potential mold spores, and your HVAC system quickly becomes a hidden source of air pollution.

PowNat’s trained technicians use advanced, mess-free techniques to remove contaminants from your ductwork and dryer vent systems. We tailor each cleaning to your building’s layout, ensuring thorough results whether you’re living in a bungalow in Old North, a condo in Downtown London, or a suburban home in Byron. Our mission is to deliver honest, high-quality service with lasting benefits for your home, your health, and your wallet.

Why London Homeowners and Businesses Need Duct & Dryer Vent Cleaning

Air ducts are the lungs of your home or building, and like any system in constant use, they collect dust, debris, and allergens over time. When the air system runs, these contaminants are recirculated into every room. If left uncleaned, they can affect not only your comfort but also your health—particularly for those with asthma, allergies, or compromised immune systems.

Dryer vents are another area where buildup becomes dangerous. Lint accumulation can reduce drying efficiency and increase your risk of a home fire. Cleaning your dryer vent is one of the most overlooked yet essential maintenance tasks for homeowners.

Benefits of Air Duct and Dryer Vent Cleaning:

Improves indoor air quality by removing dust, mold spores, and allergens
Boosts HVAC efficiency, reducing heating and cooling costs

From single-family homes to offices, schools, and commercial units, PowNat ensures every cleaning meets the highest standard for safety, efficiency, and health.

When It’s Time to Call the Professionals

While some signs of dirty ducts or vents are easy to spot, others build up quietly over time. If you’ve never had your ducts cleaned—or if it’s been more than three years—it’s worth booking an inspection.

Common Warning Signs:

You see dust or lint accumulating quickly around vents
You smell musty or smoky odors when your system runs
Allergy or asthma symptoms worsen indoors
Your HVAC system runs constantly or unevenly
Dryer takes more than one cycle to fully dry clothes
You’ve moved into a previously owned home
You’ve recently renovated your home
Your energy bills are rising without a clear reason
