If you’ve ever wondered about the cost of duct cleaning in Ontario, you’re not alone. With prices varying based on home size, the condition of the ductwork, and service providers, it’s no wonder that many homeowners in Ontario are seeking clear answers.
In this blog, we’ll break down the average cost of duct cleaning in the province, explain what influences pricing, and help you determine whether duct cleaning is worth the investment. You’ll also find practical tips for saving money without sacrificing quality.
Average Cost of Duct Cleaning in Ontario
In Ontario, duct cleaning costs generally range between $300 and $600 for an average residential home. However, the total you pay depends on a few key factors. These include the size of your home, how many air vents you have, and whether you add extra services like furnace duct cleaning or HVAC duct sanitization.
Here’s a rough breakdown:
- Smaller homes (under 1,500 sq. ft.): $300–$400
- Average-sized homes (1,500–2,500 sq. ft.): $400–$500
- Larger homes (2,500+ sq. ft. or multiple systems): $500–$700+
Some duct cleaning services near you might also offer flat-rate pricing, which can make comparing offers easier. Still, it’s always a good idea to check what’s included before booking. For example, some packages may only clean the main ducts, while others include vents, returns, furnace components, and even antibacterial treatments.

What Impacts the Cost of Duct Cleaning?
It’s easy to assume that duct cleaning is a one-size-fits-all service, but in reality, several factors influence how much you’ll pay. Understanding these elements can help you make an informed decision.
Key Cost Factors:
Home size and duct layout: Larger homes require more time and effort. More vents and longer duct runs will naturally increase the labour involved.
Duct condition: Dirtier systems—especially those not cleaned in 5+ years—take longer to clean. Homes with pets, smokers, or recent renovations often fall into this category.
Access and design: Hard-to-reach ducts or multi-story homes with limited crawl space access may add complexity and time.
Service add-ons: Services like furnace cleaning, deodorizing, or antimicrobial treatments increase the total price. Ask if these are necessary or optional.
Company reputation and equipment: Established companies that use high-powered vacuums and offer guarantees may charge more but often provide better results.
Location: If you’re in a remote or rural area of Ontario, there could be a small travel fee depending on where the company is based.
These factors explain why the cost of cleaning air ducts in Ontario isn’t always identical between homes of similar size.
Is Duct Cleaning Worth It?
So, is duct cleaning just a “nice-to-have” or an essential service? In many cases, it’s worth every penny, especially if your home has indoor air quality concerns.
Here’s when it really makes sense:
- You’ve recently completed renovations or construction
- You or your family have allergies, asthma, or respiratory sensitivities
- You notice dust returning quickly after cleaning
- Your home smells musty or you see signs of mould in vents
- It’s been over 3–5 years since your last duct cleaning
Besides reducing allergens and airborne contaminants, air duct cleaning can improve HVAC efficiency. Clean systems don’t have to work as hard to push air through clogged ducts. This can lead to energy savings over time, which helps justify the upfront cost.
How to Get the Best Value for Your Duct Cleaning
Now that you know what influences the average cost of duct cleaning, let’s talk strategy. You don’t have to break the bank to get clean, healthy air. With a few smart moves, you can get the most value for your dollar.
Here Are Some Quick Tips:
Compare quotes from local providers: Don’t settle for the first quote. A bit of research can reveal price differences of $100 or more.
Check what’s included in the price: Make sure the service includes vents, returns, main trunk lines, and the furnace unit (if needed). Avoid ultra-low prices that skip key components.
Look for duct cleaning specials in Ontario: Some companies run promotions during the spring and fall—prime HVAC maintenance seasons.
Read reviews and ask questions: Find a reputable company with positive feedback and a track record for honesty and professionalism. Ask if their team is certified or insured.
Bundle services where possible: Need a furnace tune-up or dryer vent cleaning? Bundling services can reduce your overall bill.
