Duct Cleaning Cost in Ontario: 2026 Price Guide

Professional duct cleaning in Ontario costs $399 for a typical home of up to about 2,200 square feet in 2026 — that is Vacu-Man’s flat residential rate, covering the furnace and the first 10 registers. Across the province, legitimate quotes generally fall between $300 and $600 depending on home size and vent count. Anything advertised at $99 is almost never the real final price.

Pricing for duct cleaning is one of the most confusing corners of home maintenance, because quotes range from suspicious $99 flyers to $800 invoices for the same house. This guide breaks down what duct cleaning actually costs in Ontario, what a legitimate price includes, what changes the number, and how to spot a quote that will triple once the crew is in your basement. Every Vacu-Man price below is our real, published rate.

How Much Does Duct Cleaning Cost in Ontario?

A professional furnace and duct cleaning for an average Ontario home costs $399 at Vacu-Man, which includes the furnace components and the first 10 registers and air vents, hot and cold air returns included. Additional vents are $10 each plus HST. Provincewide, honest full-system quotes typically land between $300 and $600.

The spread comes down to what is actually being cleaned. A true full-system cleaning uses truck-mounted vacuum equipment connected to your main trunk lines, cleans every supply and return, and includes the furnace itself — the heat exchanger, blower fan, and air conditioning coil. Companies quoting far below that range are usually pricing a quick shop-vac pass at the register openings, which is not the same service.

What Is Included in a Professional Duct Cleaning?

A legitimate cleaning covers the entire air path: every supply vent, every cold air return, the main trunk lines, and the furnace’s internal components. At Vacu-Man that means truck-mounted vacuums running 8,000 to 18,000 CFM, with the furnace heat exchanger, blower fan, and AC coil cleaned as part of the base price — not as add-ons.

This distinction matters when you compare quotes. Some operators price the ductwork alone and then charge separately once they “discover” the furnace needs attention. Ask any company two questions before booking: is the furnace included, and what equipment do you use? The answers separate a real cleaning from an expensive dusting.

What Changes the Price of a Duct Cleaning?

Four things move a duct cleaning quote up or down in Ontario: the number of vents, the size and layout of the home, how many furnaces or systems it has, and access. Vent count is the biggest one — a large home can have 25 or more registers, and at $10 per extra vent the total scales predictably rather than jumping.

Homes with two furnaces are effectively two cleaning jobs sharing one visit. Finished basements, tight mechanical rooms, and roof-exhausted dryer vents add working time. What should not change the price: the crew showing up and inventing problems. A company with published rates has nothing to renegotiate at your door — which is exactly why we publish ours.

How Much Does Dryer Vent Cleaning Cost?

Dryer vent cleaning in the Hamilton area runs $219 to $369 as a standalone visit, depending on where the vent exits — main floor, second floor, or roof. Booked together with a furnace and duct cleaning, it drops to $99 to $325, which is the best-value way to have it done.

Clogged dryer vents are one of the leading causes of house fires in Canada, and the warning signs — long drying times, a hot laundry room, a burning smell — tend to appear well after the lint has built up. If it has been more than a year, our dryer vent cleaning prices page covers every scenario.

Why Are $99 Duct Cleaning Offers a Red Flag?

A $99 whole-home duct cleaning does not exist as a profitable, properly equipped service — the truck, insurance, licensed labour, and time cost more than that. The $99 price is a door-opener: once inside, the crew “finds” mould, upsells sanitizing fog, and the invoice lands at three to six times the advertised number.

The pattern is common enough that we wrote a full breakdown of the $99 air duct cleaning scam and how to protect yourself. The short version: compare what is included, not the headline number, and check the company can be verified — Vacu-Man is certified by CNADCA, Canada’s national air duct cleaning association (certificate CA-00196), which you can confirm on the CNADCA member directory.

Is Duct Cleaning Worth the Cost?

For most Ontario homes, a professional cleaning every 3 to 5 years is worth it: it removes the dust, pet hair, and construction debris your system recirculates, restores airflow the furnace is fighting against, and is the only way to clean the furnace components themselves. The US EPA’s guidance on duct cleaning recommends it particularly when there is visible mould, pests, or heavy debris.

Where it is not worth paying: right after a previous cleaning, in a brand-new home that was properly cleaned post-construction, or from any company that cannot tell you exactly what their price includes. Honest answer from a company that has done this since 1980 — not every home needs it every year.

How Often Will You Pay for Duct Cleaning?

Budget for a cleaning every 3 to 5 years in a typical home — sooner after renovations, when moving into a resale home, or with multiple shedding pets. At $399 per visit, that works out to roughly $80 to $130 per year of ownership, less than most single furnace repair calls.

Our guide to how often air ducts should be cleaned covers the timing signals in detail, including the situations that reset the clock.

What About Commercial Duct Cleaning Costs?

Commercial duct cleaning in Ontario is priced by inspection, not by flat rate — buildings vary too much in ductwork length, system count, and access for a published number to be honest. Expect a site visit and a written scope before any figure is quoted.

We provide free on-site estimates for offices, buildings, and facilities, scheduled around business hours. If a commercial cleaner quotes you a flat price without seeing the building, treat it the way you would treat the $99 flyer.

Frequently Asked Questions

Does the $399 price include the furnace?

Yes. The base price covers the furnace heat exchanger, blower fan, and AC coil along with the first 10 registers and vents, including hot and cold air returns. Extra vents are $10 each plus HST — the only variable in the price.

Is HST included in duct cleaning prices?

Listed prices are before HST, which is added at Ontario’s standard 13% at invoicing. A $399 cleaning totals $450.87 with HST. Per-vent and filter charges are also plus HST — any Ontario company quoting “tax included” should show that math in writing.

How long does a duct cleaning take?

Most homes take 2 to 3 hours for a full furnace and duct cleaning. Larger homes, multiple furnaces, or an added dryer vent cleaning extend that. You will walk the system with the technician at the start, and you do not need to supervise afterward.
