Air Duct Cleaning in London, Ontario
London winters are long — and your furnace runs hard. If your home is collecting dust faster than you can clean it, or allergies are never quite under control, your ductwork is likely the problem. We're London's local solution.
Why London Homeowners Clean Their Ducts
Most people don't think about ductwork until a problem makes it impossible to ignore. Here's what dirty ducts actually cost you.
Reduce Allergens Year-Round
Ducts collect dust mites, pet dander, mould spores, and pollen. Every time your furnace runs — which in London is from October through April — those particles circulate through every room. A full clean removes the source, not just the symptoms.
Lower Your Hydro Bills
Debris buildup restricts airflow, forcing your furnace and AC to run longer to maintain temperature. Clean ducts reduce run time and energy consumption — a meaningful saving given London's long heating season.
End the Constant Dusting
If surfaces in your Byron, Westmount, or Old North home collect dust within days of cleaning, your ductwork is redistributing what's settled inside. Cleaning the ducts breaks the cycle.
Protect Your HVAC Investment
Debris on your furnace's heat exchanger and blower accelerates wear. Furnace replacement in London runs $3,000–$7,000. Routine duct cleaning is the far cheaper option — and it keeps your warranty valid.
Our Services
From routine residential cleaning to commercial HVAC maintenance, London Clear Air covers every aspect of indoor air quality.
Full Duct System Cleaning
Complete cleaning of all supply and return ducts using high-powered negative air pressure and rotary brush technology. We clean every vent register, branch, and main trunk — nothing left behind.
Furnace & Air Handler Cleaning
We clean the blower, heat exchanger, and evaporator coil as part of our full system package. A clean duct attached to a dirty furnace is only half the job — we do both.
Dryer Vent Cleaning
Blocked dryer vents are one of the leading causes of residential fires in Ontario. Beyond fire risk, a clogged vent extends drying times and raises your hydro bill. We clear and inspect the full vent line.
Sanitization & Deodorizing
After cleaning, we apply an antimicrobial sanitizer to duct interior surfaces — eliminating mould, bacteria, and odour-causing organisms. Ideal after water damage, musty basements, or homes with multiple pets.
Post-Renovation Cleanup
Renovation dust from drywall, insulation, and sawdust infiltrates your ductwork immediately. It then circulates for years unless removed. We do thorough post-reno duct cleaning for London contractors and homeowners.
Commercial Duct Cleaning
Restaurants, offices, schools, and commercial properties throughout London and the surrounding area. We clean commercial HVAC systems to industry standards with flexible scheduling to minimise disruption.

Common Questions About Air Duct Cleaning in London
Answers to what London homeowners ask most before booking.
- How often should I have my air ducts cleaned in London, Ontario?
- Most homes benefit from cleaning every 3–5 years. More frequent cleaning is recommended if you have pets, allergy sufferers, smokers, or recently completed a renovation. London's older housing stock and long heating season also favour regular maintenance.
- What does a complete air duct cleaning service include?
- A complete service covers all supply and return ducts, the main trunk line, the furnace blower compartment, and the air handler coil area. We use negative pressure and contact cleaning — not just blowing air through the system.
- How much does air duct cleaning cost in London, Ontario?
- Most London homes run $350–$600 for a complete system cleaning, depending on home size and vent count. We provide transparent pricing upfront — no bait-and-switch from a low advertised price.
- Is NADCA certification important when choosing a duct cleaner?
- Yes. NADCA (National Air Duct Cleaners Association) certification indicates training in proper cleaning methodology. There are fewer than 10 NADCA-certified companies in all of Ontario — it's a meaningful differentiator that filters out operators using inadequate methods.
- Can I have my dryer vent cleaned at the same time?
- Yes, and we recommend it. Adding a dryer vent cleaning to your appointment saves $50–$100 versus a separate visit, and blocked dryer vents are a leading cause of house fires. We clean and inspect the full vent run from the dryer to the exterior cap.
