By Adel Majd, Chief ExtraOrdinary Officer, Air Force Shield (how we write). Published in Regional GTA Guides
With Air Force Shield, duct cleaning for a Mississauga house with one furnace costs $399 to $499 before HST, depending on the size of the house. A condo suite is a flat $449. The price is set by the home, not by the number of vents and not by the city, so a house in Meadowvale costs the same as the same house in Toronto. This guide gives the full price list with HST worked out, shows how it applies to the kinds of homes Mississauga is built from, and explains why some ads quote a fraction of these numbers. Prices are current as of November 2026.

Every house price covers the full 12-step process: each supply and return run, the main trunks, the furnace J-channel, the blower and the furnace base, with before-and-after photos emailed to you. The condo fee covers the vents, the fan coil or wall unit, one bathroom exhaust fan and the dryer vent.
What that means for the homes Mississauga is built from
Mississauga is mostly two kinds of home: houses in subdivisions built from the 1970s onward, and the condo towers around the City Centre. The price list maps onto them like this.
Detached and semi-detached houses
The subdivisions built from the 1970s onward, such as Erin Mills, Meadowvale and Churchill Meadows, are detached and semi-detached houses. You pay for the size band the house falls in, plus $150 if it has a second furnace. A two-storey house has long supply runs up to the bedrooms and usually more registers than a bungalow of the same footprint. That does not change the price. We clean every run either way, and the far upstairs vents are often the ones that needed it most.
Townhouses
For a freehold townhouse with its own furnace, choose House in the quote form and the size band that fits. If the truck cannot park close to your door, tell us when you book and we bring portable equipment instead. If your townhouse is part of a condo corporation and you are not sure which price applies, call and we will sort it out in a minute.
Condo suites around Square One
The towers around Square One and the City Centre use fan coil units rather than furnaces. A suite with one unit is $449 flat, and a suite with two is $599. The dryer vent and one bathroom exhaust fan are part of that fee, so there are no add-ons to choose. The work takes about 45 minutes with portable equipment brought up to the suite. Under our Next Door Discount, two suites in the same building cleaned in the same visit are $349 each, which is worth mentioning to a neighbour. That discount is not combined with the repeat-client discount. The condo duct cleaning page has the details.
Older houses in Port Credit, Streetsville and Malton
Port Credit, Streetsville and Malton have older houses, some with ductwork that was fitted or altered long after the house was built. The price still follows the size band. What changes is the job itself, which we describe on the pages for Port Credit, Streetsville and Malton.
What changes the price, and what does not
Four things move the number:
- The size band of the house. Under 2,000 sq ft, 2,001 to 3,000, or 3,001 to 4,000. Above that we quote by phone.
- The number of furnaces. Each furnace after the first is a separate duct system and adds $150, up to three.
- Add-ons. On a house, the dryer vent, the heat recovery ventilator, the humidifier, or a set of three bathroom and laundry exhaust fans are $90 each. Book two and the third is free.
- Whether you have used us before. Repeat clients get 5% off the cleaning, though not off the add-ons.
These do not move it:
- How many vents you have. We do not price per vent.
- Where in the GTA you live. There is no separate travel charge for a Mississauga address.
- The day you pick. We work seven days a week, and a Saturday or Sunday costs the same as a Tuesday.
Why some Mississauga ads say $99 or $189
Search for duct cleaning in Mississauga and you will see ads that price a set number of vents, or a whole house for around a hundred dollars. For comparison, the US Environmental Protection Agency's guide Should You Have the Air Ducts in Your Home Cleaned? says these services typically "range in cost from $450 to $1,000 per heating and cooling system." Those are US figures, but they show the gap.
A low advertised price can only work in one of two ways. Either the price covers part of the house, such as the first ten vents, and the rest is charged on the day. Or the visit is too short to clean the trunks, the blower and the furnace base, and the money is made on what the crew finds once inside. A 2013 CBC Marketplace investigation hired Toronto duct cleaners through phone offers like these. In two homes the crews finished in about an hour and charged $115 and $99 before tax, and the expert who checked the work found the dust in one duct had not moved. Our guide to GTA duct cleaning scams goes through the warning signs.
Before you compare a per-vent ad with a whole-house price, count your own supply and return registers and multiply.
How to compare two quotes
- Per house or per vent? Ask for the total for your house, in writing, before anyone arrives.
- What is cleaned? Each supply and return run, the main trunks, the blower and the furnace base should all be named. The EPA says a provider should agree to clean all components of the system.
- Is HST included? Ours is not, which is why the table above shows both figures.
- Will you get photos? Before-and-after photos are how you check the work.
- Can you check the company? Air Force Shield is listed as a CNADCA certified company, ID CA-00153. Look up any company you are considering the same way.
- What happens if you are not happy? Our guarantee is "Love it or don't pay."
