Ajax Air Duct Cleaning

For over 60 years, National Duct has been Ontario’s trusted name in air duct cleaning and dryer duct cleaning—and in Ajax, we continue that legacy by helping homeowners and businesses enjoy cleaner air, safer spaces, and more efficient HVAC systems. Whether you’re living in a lakeside home in Southwood, managing a property near Downtown Ajax, or raising a family in Nottingham, we bring proven expertise and industry-leading service to every job.

Ajax experiences all four seasons, and that constant shift in temperature means your HVAC system is always working. Over time, air ducts accumulate dust, pollen, pet dander, mold spores, construction debris, and other contaminants. Left untreated, this buildup can compromise your indoor air quality, aggravate allergies, and reduce the efficiency of your heating and cooling system.

At National Duct, we offer a deep clean for your air duct system—eliminating hidden dust and improving airflow throughout your home or building. We also provide thorough dryer duct cleaning, which helps reduce fire hazards and improve your appliance’s performance. We are fully certified, insured, and experienced in servicing all types of duct systems, from new builds to heritage homes.

Clean Air Starts Here

Your HVAC system circulates air through your property multiple times a day. That means whatever is trapped in your ductwork—dust, allergens, pollutants—is also being pushed into the air you breathe. Professional duct cleaning from National Duct targets this hidden pollution source and removes it completely.

We don’t cut corners. We clean the entire ductwork system, including supply and return ducts, grilles, diffusers, and other components. Our team uses proven techniques to ensure thorough results without damaging your system.

The Benefits of Air Duct and Dryer Duct Cleaning

Improved indoor air quality — reduce airborne allergens, pollutants, and dust
Enhanced HVAC efficiency — your system doesn’t work as hard, lowering your energy bills
Fewer dust particles — enjoy a cleaner home with less frequent cleaning required
Odor elimination — remove smells caused by mold, pets, or smoke trapped in ducts
Longer system lifespan — clean ducts reduce wear on your furnace and AC

Whether you’re a homeowner looking for a cleaner environment or a property manager seeking to maintain multiple units, our service helps protect both your property and the people inside it.

When It’s Time to Schedule Air Duct Cleaning

Air duct systems can hide years of contaminants—and because the buildup happens slowly, many property owners don’t realize there’s a problem until symptoms arise. If your home or business hasn’t had its ducts cleaned in the last 3 to 5 years, it’s time to act.

Signs You May Need Duct Cleaning:

You’ve recently moved into a new or previously owned home
You’ve completed renovations or remodeling work
Your HVAC system runs constantly or feels less effective
Dust builds up quickly on furniture and surfaces
You or your family are experiencing indoor allergy or asthma symptoms
There are noticeable musty or stale odors when the system runs
Your dryer takes longer to dry clothes or feels excessively hot

In addition to homes, we service:

Apartment buildings and condominiums
Retail stores and restaurants
Medical and dental offices
Office buildings and commercial spaces
Multi-unit rental properties and property management portfolios

No matter the size or age of your building, we deliver consistent, quality results you can rely on.
