Duct cleaning in Lisgar
A 1990s neighbourhood arriving at its first duct cleaning all at once — original construction debris included.
Call (647) 694-2283Everything here was built at the same time
Lisgar went up almost entirely through the 1990s, which means the whole neighbourhood reaches the same maintenance milestones together. Furnaces got replaced across the area in a fairly tight window, and ductwork — which nobody tracks, because it gives no failure signal — largely did not.
The practical result is that a large share of Lisgar homes are still on their original ducts thirty years on, and we are frequently the first cleaning. Original construction debris — drywall fragments, sawdust, the occasional offcut — is routine in the trunk lines.
New furnace, old ducts
This is the most common pattern we see here. A high-efficiency furnace goes in, the homeowner expects a noticeable improvement, and it never quite arrives — because the new blower is pushing air through thirty years of accumulation in the same ductwork.
If you replaced your furnace in the last few years and the result underwhelmed, clean the ducts before you conclude the furnace was oversold.
Flex branches need soft-whip agitation
Housing of this era typically pairs rigid trunk lines with flexible duct on the final runs into rooms. Flex tears under aggressive rotary brushing, and a torn liner sheds fibres permanently — a worse outcome than leaving it dirty.
We use compressed-air whips on those branches. It is slower and it is the correct method.
Osprey Marsh and the west edge
Homes backing onto Osprey Marsh and the trail system take on more pollen and organic debris in spring and fall than homes in the interior of the neighbourhood. Households with seasonal allergies on those streets do better on a two-to-three-year interval than the usual three-to-five.

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.
