London Air Duct Cleaning

Welcome to National Duct, your trusted provider of professional air duct cleaning and dryer duct cleaning in London, Ontario. For more than 60 years, we’ve helped residents and businesses across the province enjoy cleaner air, improved HVAC performance, and safer homes. Whether you’re in a modern home in Byron, a downtown apartment near Woodfield, or a heritage house in Old South, we’re here to serve your air quality needs with skill and integrity.

London’s seasonal extremes—humid summers, frigid winters, and dusty construction seasons—can overload your HVAC system, allowing debris, allergens, mold spores, and dust to settle in your ductwork. Over time, these contaminants can degrade your air quality, drive up your energy bills, and create health risks for those with allergies or respiratory concerns. Dryer vents are another common hazard, often clogged with lint that restricts airflow, increases drying times, and poses a fire risk.

At National Duct, we clean every duct and dryer vent with care and precision, using proven tools and techniques. Our licensed professionals don’t cut corners, and we never push unnecessary add-ons. Instead, we provide clean, safe air solutions that work—because your health and comfort matter.

Why Air Duct and Dryer Vent Cleaning Matters in London

Your ductwork is like the lungs of your home. Every time your HVAC system runs, air passes through this hidden network of vents and returns, collecting and redistributing whatever is trapped inside—dust, allergens, pet dander, bacteria, and moisture. Left uncleaned, these substances build up and circulate continuously, polluting your indoor air and reducing system performance.

Dryer vents, meanwhile, are often ignored until they become a problem. When lint and debris block the exhaust, drying becomes inefficient and unsafe. In fact, clogged dryer vents are one of the leading causes of preventable house fires in Ontario.

Benefits of Duct and Dryer Vent Cleaning:

Improves indoor air quality by removing allergens, dust, and contaminants
Enhances HVAC efficiency, reducing monthly utility costs
Extends the life of HVAC and dryer systems
Reduces musty odors and improves overall freshness
Decreases risk of dryer-related fires
Minimizes household dust on furniture and surfaces
Restores even airflow and consistent temperatures
Improves respiratory health for those with allergies or asthma

Whether you’re in a downtown apartment, suburban home, or commercial space, regular duct and dryer vent cleaning makes your indoor environment safer and more comfortable.

When to Schedule Duct Cleaning in London

Not sure if it’s time to call in the pros? Many London homes benefit from duct cleaning every 3–5 years, but some systems require more frequent service—especially homes with pets, allergy sufferers, or after renovations.
