What is the cost of air duct cleaning after a home renovation in Ottawa?

Quotes for air duct cleaning after a home renovation in Ottawa can run roughly $400 to $800 for a typical residential system, though the final price depends on your home and the scope of the renovation work. Treat that as perspective, not a price list. Post-construction duct cleaning can cost more than routine maintenance cleaning, because there is usually more dust to remove and the job takes longer.

What Drives the Cost in Ottawa

The size of your HVAC system is a major cost factor — a smaller home with fewer vents will usually come in lower than a larger home with many vents. Homes with multiple HVAC zones or separate systems for different floors will cost more because each system requires independent cleaning. The type of renovation also matters considerably — a kitchen remodel that generated moderate dust will require less intensive cleaning than a full gut renovation that produced months of drywall compound, concrete dust, and sawdust throughout the home.

Add-on services that are often offered with post-renovation duct cleaning also affect the total. Dryer vent cleaning, furnace blower and evaporator coil cleaning, and sanitizing or deodorizing treatments are usually priced separately. Blower and coil cleaning can be worth asking about after major construction, because those parts can collect a lot of fine dust, and a deodorizing treatment may help if paint, adhesives, or sealants left lingering odours. Ask for an itemized written quote that lists each add-on and its price, so you can choose what you actually need.

Be cautious of very low advertised prices for whole-home duct cleaning. Some low-price offers are used to get in the door and then upsell once the crew arrives. Before booking, ask exactly what the quoted price includes — the number of vents, the main trunk lines, the returns, and the furnace — and get it in writing.

Timing matters for both pricing and results. Schedule duct cleaning as the final step in your post-construction cleaning process — after all surface cleaning, floor scrubbing, and detail work is complete. If you clean the ducts first and then do heavy surface cleaning that stirs up dust, the airborne particles will settle right back into the ductwork. Booking a little ahead helps, since schedules can fill up. Get at least three written quotes, ask each company for proof of liability insurance and what it covers, and ask whether they have WSIB coverage or a clearance certificate.
