- No licensing applies; NADCA certification is the voluntary standard. Provincial consumer-protection offices (and the Competition Bureau) have repeatedly warned about telemarketed duct-cleaning scams, so verify companies independently.
- Prices below are researched national ranges, updated July 2026 — not quotes.

What affects the price
- Job size and scope — bigger or more complex jobs move you up the ranges above.
- Access and condition — hard-to-reach areas, older properties or neglected maintenance add labour time.
- Materials and quality level — where materials are involved, the grade you choose often matters more than labour.
- Urgency — same-day or out-of-hours work usually carries a premium.
- Where you live — large metros in Canada typically run above the national range; smaller towns below it.

- Be flexible on timing — off-peak slots are often cheaper.
- Bundle related tasks into one visit to spread call-out costs.
- Agree the scope in writing up front to avoid change-order surprises.

Frequently asked questions
How long does whole-house duct cleaning take?
A typical single-system home takes 2-4 hours with a two-person crew. Larger homes, multiple air handlers, or heavy contamination stretch to a full day. Be suspicious of anyone promising a whole house in under an hour.
What is the duct cleaning scam I should watch for?
The pattern: a $50-100 'whole house special', then on-site claims of hidden mould with photos that may not be from your ducts, pressure-selling sanitizer fogging at hundreds extra. Legitimate firms quote by vent/system count, show you findings in your own ducts, and never pressure same-day decisions.
Should ducts be sanitized or fogged with biocide after cleaning?
Usually no — blanket chemical fogging is discouraged unless there's confirmed microbial growth and the product is approved for HVAC use. Mechanical cleaning plus fixing the moisture source addresses the cause; fogging is the most-upsold, least-needed add-on.
How is air duct cleaning priced?
Usually per system or per vent: a flat whole-house price for an average system, with surcharges for extra vents, multiple air handlers, or heavy contamination. Dryer vent cleaning is typically a smaller separate line item.
What does professional duct cleaning actually involve?
Proper source-removal cleaning puts the system under negative pressure with a high-power vacuum, then agitates each duct run with rotating brushes or compressed-air whips so debris is pulled to the collector — not blown into the house. Register covers, the air handler, and coils should be included.
How often should ducts be cleaned?
There's no fixed schedule — clean when there's visible mould, vermin, renovation dust, or significant debris buildup. In practice every 3-5 years is typical for forced-air homes, sooner after building work or if filters blacken quickly.
Does duct cleaning improve air quality or health?
Evidence is mixed for routine cleaning of already-clean ducts. It clearly helps when ducts contain mould, construction dust, pest debris, or blockages. Pairing cleaning with better filtration and sealing duct leaks delivers more measurable benefit than cleaning alone.
When should Canadians clean their ducts?
After renovations, before first winter in a resale home, or when filters blacken fast — typically every 3-5 years. Book before heating season; crews are cheapest in late spring and summer when furnaces are idle.
