Duct cleaning in Clarkson
Post-war housing near the lake and Rattray Marsh, where humidity does as much damage as dust.
Call (647) 694-2283Humidity is the local problem
Clarkson sits between Lake Ontario and the Rattray Marsh, and homes on the south side carry noticeably more ambient humidity than the rest of Mississauga through summer and the shoulder seasons.
In a duct system that shows up in two specific places. The evaporator coil stays wet longer and holds more of what passes over it, and the condensate drain pan is slower to clear — which is where a musty smell on AC startup usually originates. Cleaning the ducts without doing the coil and pan on a Clarkson home often leaves the actual complaint unresolved.
If your call is about a smell rather than dust, say so, and we will plan for the coil from the start.
The post-war core
The housing around the village and the GO station is largely 1950s to 1970s — bungalows, side-splits and modest two-storeys with conventional rigid ductwork. These clean up well and typically run 12 to 18 vents, which puts most of them in the $249 or $349 package.
What we find most often is simply time: systems that were last cleaned when the current owners moved in, or never.
Basements
Finished basements are near-universal here and they are the usual source of a whole-house smell. A damp basement feeds the cold-air return, and the return distributes it to every room.
We will clean the system and it will help. But if the underlying moisture is not addressed, the smell returns, and we would rather tell you that than book you again in eight months.
Worth doing together on this side of the city
- Duct cleaning and AC evaporator coil, $89 as an add-on
- Condensate drain pan cleared and the line flushed
- Dryer vent, which packs faster in humid air
- Antimicrobial fogging where there is confirmed growth — not by default

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 often should ducts be cleaned?
Every three to five years suits most Mississauga homes. Move that to every two to three years if you have pets that shed, someone in the house with asthma or allergies, or a finished basement that generates a lot of dust.
Two situations override the schedule entirely: after any renovation involving drywall or sanding, and immediately after moving into a home whose duct history you do not know.
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.
Should I clean my ducts before or after a renovation?
After, always. Drywall dust is fine enough to travel the entire duct system and it keeps recirculating for months. Cleaning before the work simply means paying to clean ducts you are about to fill.
If the renovation is still ongoing, seal the registers in the work area with plastic and tape, and book the cleaning once the sanding is finished.
Are you insured, and are your technicians certified?
Ask this of every company you call, and ask for the certificate rather than accepting the claim. The relevant credentials in this trade are NADCA (National Air Duct Cleaners Association) membership and liability insurance covering work inside your home.
Any company that will not produce proof of insurance in writing before the appointment should be ruled out — you are letting them open your furnace.
