Before
AfterYour ductwork is the lungs of your Thornhill home
Thornhill started out as Thorne’s Mills, named after Benjamin Thorne, who built a gristmill, sawmill, and tannery here after arriving from England in 1820, joining earlier settlers Asa Johnson and Nicholas Miller who’d founded the community back in 1794. It grew steadily as a Yonge Street stagecoach stop through the 1830s and 40s, then got a second wind once the electric streetcar opened in 1898, letting people live here and commute into Toronto for work. It became its own police village in 1931 before York Region’s creation in 1971 folded it back under Vaughan and Markham. It’s actually split down the middle by Yonge Street between the two, so depending on which side of the road we’re working on, the building era and duct layout can look pretty different.

Start to finish, in one visit.
On a Thornhill job, the return duct told the whole story: years of dust and debris built up well past what any filter could stop. Our technician cleared the full system with high-suction equipment and finished with a disinfectant pass before wrapping up.

How often should air ducts be cleaned?+
Every 3-5 years is a good general rule for most homes, sooner if you’ve had renovation work, pets, or allergy concerns.
Will duct cleaning actually help with allergies?+
It can help by removing dust, pollen, and pet dander that recirculate through the system, though it isn’t a substitute for a proper air filtration setup.
What does air duct cleaning cost in the GTA?+
It varies by home size and duct layout, so we ask a few quick questions over the phone to give you an accurate price upfront. For bigger or more complex jobs we’ll assess on-site before quoting, and we always walk the home with you before starting in case anything changes.
What are the signs my ducts need cleaning?+
Visible dust puffing from vents, a musty smell when the system starts, weak airflow in certain rooms, or signs of pests are the clearest signals, not just how many years it’s been.
Does duct cleaning help after a renovation?+
Yes. Drywall dust and sawdust get pulled into the return air and recirculated long after the cleanup crew leaves, so post-reno cleaning is one of the clearest cases where it’s worth doing.
How long does a duct cleaning appointment take?+
Most homes take 2 to 4 hours depending on vent count, duct layout, and how accessible the furnace area is.
Is Can Do Duct Cleaning BBB accredited?+
Yes, we’ve been a BBB member since 2019, alongside our TSSA G2 certification and HomeStars track record.
