What is the average cost of whole-home air duct cleaning after construction in Ottawa?

Quotes for whole-home air duct cleaning after construction in Ottawa can run roughly $400 to $800 for a typical residential system, and more for larger or more complex HVAC setups — homes with two zones, several returns, or extensive ductwork. Treat that as perspective and ask for itemized written quotes, since post-construction duct cleaning can be more involved than routine maintenance cleaning.

The reason it can cost more is the volume and type of debris. Construction dust, particularly drywall compound, concrete dust, and sawdust, can build up in ductwork more heavily than normal household dust. Duct cleaning companies use powerful vacuum systems — truck-mounted or portable — together with agitation tools like rotating brushes and compressed air whips that loosen caked-on debris inside the ducts.

In Ottawa, duct cleaning after construction matters because of the long heating season. If your renovation took place while the furnace was running, fine construction dust may have been pulled into the return air vents and spread through the duct network, including sections far from the renovation area. Every time the furnace cycles on, that dust can be blown back into the home, undoing some of the surface cleaning you have done. Skipping duct cleaning after heavy construction can leave you with lingering dust despite repeated surface cleaning.

When getting quotes for post-construction duct cleaning in Ottawa, make sure the price includes all supply vents, all return vents, the main trunk lines, the furnace blower compartment, and the evaporator coil area. Some companies advertise low base prices but charge per vent or exclude the furnace compartment, which can collect a lot of construction debris. Ask what equipment the company uses and how it reaches the main trunk lines. It is also reasonable to ask for before-and-after photos or camera footage from inside the ducts.

Be cautious of quotes that look far lower than the rest, and ask exactly what they include — a very low price may mean only part of the system gets cleaned. Ask each company for proof of liability insurance and what it covers, and ask whether they have WSIB coverage or a clearance certificate. Get at least three written quotes and confirm the scope of work in writing.
