Short answer: a full, proper duct cleaning for a typical house in Toronto, Vaughan, Richmond Hill, Aurora or Newmarket usually costs a few hundred dollars, commonly in the range of about $300 to $700. Larger homes, homes with two furnaces and add-ons like dryer vent cleaning cost more. Offers far below that, such as “$99 whole-house duct cleaning”, almost always grow once the crew is inside.
What changes the price
- Number of vents. More supply and return openings means more runs to brush and extract.
- Size and layout of the home. Bungalows, two-storeys and homes with finished basements all take different amounts of time.
- Number of furnaces. Larger homes in Vaughan, Richmond Hill and Markham often have two systems.
- How dirty the system is. Renovation dust, new-build debris, pets and years without cleaning all add time.
- Add-ons. Dryer vent cleaning, antimicrobial treatment and furnace blower cleaning.
- Access. Condos can involve elevator bookings and parking.
What a proper duct cleaning should include
- Every supply and return duct, not just the main trunk
- Registers and return grilles removed and cleaned
- The furnace blower area and cold air return
- Mechanical agitation with rotating brushes, plus strong extraction
- Protection for floors and walls at every opening
- A chance to see what came out

Why $99 duct cleaning rarely stays $99
A very low advertised price usually covers a few vents or the main trunk only. Once the crew is inside, extra charges are added for each vent, the furnace, “mould treatment” or “sanitizing”. Ontario homeowners have complained about these tactics for years, which is part of why the province changed the law.
Ontario law protects you
Since March 1, 2018, duct cleaning cannot be sold at your door in Ontario unless you invited the company first. A contract signed that way is void. Contracts for duct cleaning signed at home also come with a 10-day cooling-off period, during which you can cancel. If someone knocks offering duct cleaning, you do not have to let them in.
Is duct cleaning worth the money?
It is worth it when there is something to remove: renovation or construction dust, years of buildup, pet hair, pests or a musty smell when the furnace starts. It is not a cure-all, and a good company will tell you if your ducts do not need cleaning yet. Read how often you should clean your air ducts.
How to compare quotes
- Ask for a written quote for the whole job, including every vent and the furnace.
- Ask what equipment is used. Rotating brushes plus strong extraction clean far better than suction alone.
- Ask what add-ons cost before the crew starts.
- Check recent reviews from your area.
- Avoid anyone who sells at the door or pushes same-day upgrades.
Frequently asked questions
How long does duct cleaning take?
A few hours for most houses, longer for large homes or two furnaces.
Is dryer vent cleaning included?
It depends on the company. Ask. It is worth adding, because lint buildup is a fire hazard.
Do condos cost less?
Condo systems are usually smaller, but long dryer vent runs and building logistics can add time.
