Duct Cleaning in Markham
Full negative-pressure air duct cleaning with before-and-after camera footage.
Most duct cleaning is a vacuum held at the register for ninety seconds. Ours is a truck-mounted negative-pressure clean with rotating brush heads driven the full length of every branch, and we show you camera footage of each trunk before and after so you can see what actually came out.

Local context
Duct Cleaning for Markham homes
Markham's heritage properties around Unionville often have ductwork added long after the house was built, routed through joist spaces that were never sealed. Those cavities pull in insulation fibre continuously and need the return side cleaned as carefully as the supplies.
Duct systems collect construction dust, drywall compound, pet dander, insulation fibre and — in older GTA homes — decades of fine soot from when the same chimney served an oil appliance. None of that leaves on its own. It sits in the horizontal trunk lines and gets re-entrained every time the blower starts.
A proper clean means putting the entire system under negative pressure at the furnace, then agitating each branch mechanically so the debris travels to the collection unit instead of into your living room. We clean supplies, returns, the return plenum, the blower compartment and the evaporator coil face, then fit a fresh filter and record the static pressure so you can see airflow improved rather than take our word for it.
The difference between a real duct cleaning and a vacuum at the register is measurable. We put the system under negative pressure at the trunk, agitate each branch mechanically so debris travels toward the collection point rather than into the room, and clean the return side and blower wheel — which is where the heaviest accumulation almost always is. A blower wheel with loaded fins moves substantially less air than a clean one, and no amount of register-level vacuuming touches it.
We record static pressure before and after so the result is a number rather than a claim. If your system was not meaningfully restricted, the reading will barely change and we will tell you that plainly. Duct cleaning is worth doing on the right schedule and after the right events — a renovation, a move, a rodent problem, visible debris — and it is not an annual necessity on a clean, well-filtered system.
What the housing stock in Markham means for this job
Cornell, Berczy Village, Cathedraltown and Box Grove are planned post-1995 communities with rear-lane garages, narrow lots and mechanical rooms designed to the minimum footprint. Unionville and Main Street Markham hold protected heritage properties where any exterior work has to respect the original materials. For duct cleaning, that matters because the work concentrates on the return side and the blower wheel — and that is exactly what changes between a Berczy Village property and a newer build in Cathedraltown.
Timing in Markham
Late spring and early autumn are the sensible windows: the system is off, and cleaning before a heating or cooling season starts means you are not circulating what was disturbed. undefined Markham's inland position gives it colder winter nights than the lakeshore and a longer heating season than downtown Toronto, and its newer neighbourhoods have limited mature canopy, so summer roof and attic temperatures run high.
What it costs here
The number of supply and return branches, the number of separate systems in the house, and the condition of the trunk lines set the price far more than square footage does. Rear-lane and narrow-lot homes in Cornell and Berczy add access time for anything involving exterior equipment or roof work. In the heritage districts, material matching — mortar, brick, flashing detail — is the cost driver rather than labour hours.
Permits and jurisdiction
City of Markham issues permits, with heritage districts adding a separate approval step for visible exterior work. York Region covers water and wastewater; TSSA governs gas work throughout.

- Number of supply and return openings — pricing is per opening, not per hour
- Whether the home has one system or multiple zones and furnaces

FAQ
Duct Cleaning questions from Markham homeowners
How often should ducts be cleaned in {city}?
Every three to five years for a typical {city} home, sooner after a renovation, after buying a home, or if anyone in the house has asthma or a dust allergy. Annual cleaning is marketing, not maintenance.
Does duct cleaning actually improve airflow?
It does when the system was genuinely restricted — we record static pressure before and after so the difference is measurable rather than claimed. On a clean, well-maintained system the airflow gain is small and we will tell you that up front.
Do you clean the dryer vent at the same time?
Yes, and it is worth bundling. The equipment is already on site, and the dryer vent is the single highest fire-risk duct in the house.
How long does a duct cleaning take?
Three to five hours for an average {city} home with one furnace. Larger homes with two systems run most of a day.
What do you usually pull out of ducts in homes around here?
Cornell, Berczy Village, Cathedraltown and Box Grove are planned post-1995 communities with rear-lane garages, narrow lots and mechanical rooms designed to the minimum footprint. Unionville and Main Street Markham hold protected heritage properties where any exterior work has to respect the original materials. On a duct cleaning visit in Berczy Village, Cathedraltown, Box Grove or anywhere else in Markham, we work from what the house actually is rather than a standard checklist — the return side and the blower wheel gets assessed on the property, and you get the readings in writing.
How often do ducts actually need cleaning in this area?
Late spring and early autumn are the sensible windows: the system is off, and cleaning before a heating or cooling season starts means you are not circulating what was disturbed. Markham's inland position gives it colder winter nights than the lakeshore and a longer heating season than downtown Toronto, and its newer neighbourhoods have limited mature canopy, so summer roof and attic temperatures run high. We cover Markham from Berczy Village through Box Grove, and also serve 3 neighbouring municipalities, so scheduling outside a demand spike usually means a same-week window.
