What a real duct cleaning involves
The work that matters happens at the trunk line, not at the register openings. A high-volume vacuum is connected near the furnace and puts the entire duct system under negative pressure, so everything loosened travels toward the vacuum instead of being pushed into your rooms.
Each individual run is then agitated — compressed-air whips for flexible or lined duct, rotating brushes for rigid sheet metal — driving debris back down the branch and into the trunk. The furnace blower compartment, which collects more buildup than any other single component, is opened and cleaned by hand.
How we price it
By vent count, not square footage. Count the registers in every room including the basement and you can work out your own price from the pricing page before you speak to anyone. The first cold-air return is included; additional returns are $35 each.
When your ducts actually need it
- Three to five years since the last cleaning, or never
- After any renovation involving drywall, sanding or demolition
- You have just moved in and do not know the system's history
- Visible dust blowing from registers when the blower starts
- Pets that shed, or someone in the house with asthma or allergies
One honest caveat: if your system is clean and dry and none of the above applies, you may not need this yet. We would rather tell you that on the phone than take the booking.
Questions
How much does duct cleaning cost in Mississauga?
Duct cleaning in Mississauga typically runs $249 to $499 for a house, and around $179 for a condo. Our own flat rates are $249 for up to 10 vents, $349 for up to 20 vents, and $499 for an unlimited deep clean with sanitizing.
The number that actually moves your price is the vent count, not the square footage. Count the registers in every room including the basement, and you can price the job yourself before you call anyone.
Why do some companies advertise $99 duct cleaning?
Because $99 is a door-opener, not a price. That figure almost always covers a fixed number of vents — often six — with everything past that billed per vent on the day, plus separate charges for the furnace, the returns and a mandatory sanitizing treatment.
A homeowner who booked $99 commonly signs for $400 to $600. This is the single most frequent complaint in Ontario duct cleaning reviews. Ask any company for the all-in number for your specific vent count before booking, and get it in writing.
How long does a duct cleaning take?
Two to three hours for a typical Mississauga detached home, around 90 minutes for a townhouse, and 45 to 60 minutes for a condo suite.
Be sceptical of anyone in and out in under an hour on a full house. Putting the system under negative pressure and agitating each run back to the trunk takes time; a quick pass at the register openings is not a duct cleaning.
What actually happens during the cleaning?
A high-volume vacuum is connected to the trunk line near the furnace, putting the whole duct system under negative pressure so everything loosened travels toward the vacuum rather than into your rooms.
Each supply and return run is then agitated with compressed air whips or rotating brushes, driving debris back to the trunk. The furnace blower compartment and cabinet are cleaned by hand. A camera pass before and after shows you what came out.
Can duct cleaning damage my furnace or ductwork?
Not when done properly. Flexible duct and older fibreglass-lined duct do need a lighter touch — aggressive rotary brushing can tear the liner, which makes the problem permanently worse.
Tell whoever you hire if you have flex duct or interior insulation so they use soft-whip agitation instead. If a technician cannot tell you which method they are using on your system, that is a reason to keep looking.
Do I need to be home during the cleaning?
Yes, for the start and the end. Someone needs to let the technician in, show them the furnace and the panel, and confirm the vent count that sets the price.
Staying for the final camera pass is worth it — that is your one chance to see the inside of your own ducts and confirm the work was actually done.
Do you charge extra to come to my part of Mississauga?
No. The flat rates are the same in Meadowvale, Malton, Port Credit, Lorne Park and everywhere between. There is no travel surcharge for the west end and no premium for the lakeshore.
What is a cold-air return and why does it affect the price?
Cold-air returns are the large intake grilles — usually one per floor, often in a hallway or at the bottom of the stairs — that pull air back to the furnace. They are not the small registers that blow air out.
They matter because they collect the most debris in the whole system and are physically bigger to clean. Your first return is included in every package; additional returns are $35 each.
