Quick Answer
Professional duct cleaning for a typical GTA house costs $300 to $700, depending on home size, number of vents, and system accessibility. Larger homes or systems with significant buildup can run $700–$1,000+. Be wary of $99–$150 phone offers — they're usually bait for high-pressure upselling and rarely include the truck-mounted vacuum equipment a proper cleaning requires.
Duct cleaning pricing in the GTA spans a suspicious range — from $99 robocall specials to $1,000+ quotes for the same house. The difference is almost entirely in what's actually done. Here's what legitimate pricing looks like, what drives it, and how to avoid the industry's well-documented scams.
Realistic GTA pricing
- Townhouse or small bungalow (up to ~10 vents): $300–$450
- Typical detached 2-storey (10–20 vents): $400–$700
- Large home (20+ vents, multiple returns or systems): $700–$1,000+
- Add-ons: dryer vent cleaning $100–$200, furnace blower compartment cleaning $75–$150, sanitizing fog $100–$200
What a proper cleaning includes
- Negative-pressure vacuum (truck-mounted or HEPA portable) connected to the main trunk
- Agitation of every supply and return run with rotating brushes or air whips — not just vacuuming at the registers
- Cleaning of supply and return trunks, not only the branch runs
- Furnace blower and evaporator coil compartment inspection
- Before/after photos or camera inspection on request
The $99 special, decoded
Ultra-cheap offers are a sales channel, not a service. The visit typically consists of a shop-vac at a few registers, followed by 'discovering' mould or contamination that requires hundreds of dollars in remediation, UV lights, or sanitizer. The Competition Bureau and provincial consumer agencies have warned about this pattern for years. A real crew with proper equipment can't profitably clean a whole duct system for $99 — the truck alone costs more per day to run.
Is it worth the money?
Duct cleaning isn't an annual necessity — see how often ducts should be cleaned. But it delivers clear value after renovations (drywall dust is the #1 reason), in newly purchased homes with unknown history, after pest or mould issues, and when vents show visible debris. Pairing cleaning with duct sealing is often the smarter spend: sealing leaky joints improves airflow and cuts the dust influx that dirties ducts in the first place.
