Duct Cleaning Cost in Oshawa
$320 – $850per home
A proper air duct cleaning in Durham Region costs between $320 and $850 depending on vent count, furnace access and whether the return trunk is cleaned. The $99 flyer price is a door-opener: it buys a vacuum at a few registers, not a negative-pressure clean of the system.
Most Oshawa lots allow driveway parking and direct ladder access, which keeps sweep and inspection pricing at the low end. Cost climbs on the tall three-storey Windfields and Taunton elevations where a roof harness or lift is required, and on downtown heritage brick where repointing has to match the original mortar.

The detail
How duct cleaning cost is priced
A real clean puts the house under negative pressure with a truck- or portable-mounted HEPA collector, then agitates every supply and return branch back toward that vacuum with rotary brushes or compressed-air whips. The furnace blower compartment, the evaporator coil face and the return trunk are part of the job, because that is where the load actually collects.
Vent count is the honest unit of pricing. A 1,200 sq ft townhouse with 12 vents is a different job from a 3,000 sq ft detached home with 28 vents on three trunk lines, and any company that prices both identically is either overcharging one or shortchanging the other.
Duct cleaning is worth doing after renovation dust, after a rodent or mould finding, when you have visible debris at the registers, or roughly every three to five years in an average home. It is not an annual service, and anyone selling it as one is selling you a subscription.
In Oshawa, Downtown Oshawa and the McLaughlin blocks hold pre-1940 brick with original masonry chimneys, many of them unlined or lined with clay tile that has spalled. The 1980s-to-2000s Samac, Windfields and Eastdale builds run zero-clearance factory fireplaces with B-vent or direct-vent terminations, and the newest Kedron and Taunton homes are direct-vent gas with sealed combustion and condensing furnaces sharing the mechanical room. That shows up directly in what this job costs here compared with the rest of Durham Region.
What pushes the price up
- Total supply and return vent count, not square footage alone
- Post-renovation drywall dust, which takes multiple passes
- Additional furnaces or air handlers in the same home
- Add-ons: dryer vent, coil deep clean, antimicrobial fog, new filter
What brings it down
- Combining duct and dryer vent cleaning in one visit
- Clearing furniture from registers before the crew arrives
- Booking outside the spring allergy rush
FAQ
Duct Cleaning Cost questions we get asked
How much does duct cleaning cost in Oshawa?
Between $320 and $850 for most homes. Vent count is the main factor: a 10-vent condo is near the bottom, a 25-vent detached home with two trunks is near the top.
Why are some duct cleaning ads $99?
Because $99 does not cover a negative-pressure clean of a whole system. It typically buys a shop vacuum at a handful of registers, and the real price appears on site as add-ons. We quote the full job up front.
How often should air ducts be cleaned?
Every three to five years for a typical Durham Region home. Sooner after renovations, after a rodent or mould issue, or if you see debris blowing from the registers.
Does duct cleaning help with allergies?
It removes accumulated dust, pet dander and construction debris from the system, which usually reduces circulating particulate. It is not a cure for allergies, and we won't sell it as one.
How long does duct cleaning take?
Two to four hours for most homes. Large homes with multiple trunk lines or heavy renovation dust take most of a day.
