Three quotes. Three completely different numbers. One is under a hundred dollars, the next is several hundred, and the third will not tell you a thing until a technician is standing in your hallway. Duct cleaning cost is the most confusing part of this whole service, and a lot of the time it is confusing on purpose.
We clean ducts across Ottawa every week, from 1960s bungalows in Alta Vista to new builds in Barrhaven. The question we hear before anything else is always the same one. What is this going to run me?
Fair question. So here is the honest version: what your duct cleaning cost is actually made of, which parts of a quote are real, and which parts are a setup for an upsell once the van is in your driveway.
How Much Is Duct Cleaning? The Short Answer
There is no single price, and anyone who gives you one over the phone in ten seconds has not asked enough questions yet. Your duct cleaning cost comes down to how much ductwork you have, how dirty it is, and what equipment the job needs.
A two bedroom condo with eight vents and a shared system is a different job than a four bedroom home in Kanata with two furnaces, a finished basement, and 30 supply runs. Same service name. Very different amount of work.
What you should expect from any honest company is a clear count before the work starts: how many supply vents, how many returns, how many systems. That count is the backbone of your duct cleaning cost. If a company will not tell you what they are counting, that is your first warning.
Why a real duct cleaning cost needs a few questions first
Ask us for a number and we will ask you about square footage, vent count, whether you have a finished basement, and when the ducts were last done. Takes about two minutes. Those answers move the price more than anything else, and guessing at them is how homeowners end up with a bill that does not match the quote.
7 Factors That Change Your Duct Cleaning Cost
Every quote you get is built from the same handful of variables. Once you can see them, comparing two companies gets a lot easier.
| Factor | Effect on your duct cleaning cost |
|---|---|
| Number of vents and returns | The single biggest driver. More openings means more time, more access, more labour. |
| Number of HVAC systems | Two furnaces means two full cleanings. Common in larger Stittsville and Manotick homes. |
| Ductwork condition | Heavy dust, pet hair, or drywall dust from a reno all add time at the vacuum. |
| Access | Ducts buried behind finished ceilings or tight crawlspaces take longer to reach. |
| Add-on services | Dryer vent, furnace blower, or air exchanger cleaning are separate jobs, not freebies. |
| Equipment used | Truck-mounted vacuum and rotary brushes cost more to run than a shop vac. They also actually work. |
| Season and scheduling | Fall is our busiest stretch in Ottawa. Booking off-peak can open up better availability. |
Notice what is not on that list. Square footage alone does not set your duct cleaning cost. We have cleaned 1,400 square foot homes with more vents than a 2,600 square foot one, because the original installer ran the system differently.
The $99 Duct Cleaning Cost Trap
You have seen the flyer. Whole home duct cleaning, unlimited vents, $99. Maybe it came with a coupon for a free furnace inspection.
Here is what we walk into after those visits. A homeowner in Orleans called us last fall because her 99 dollar special ended up several hundred dollars higher. The crew arrived, ran a portable vacuum for 20 minutes, then told her the system was contaminated and needed sanitizing, antimicrobial fogging, and a coil treatment. None of it was in the ad.
The low number is not the service. It is the door. A real duct cleaning cost has to cover a full day of a technician, a commercial vacuum, and the fuel to get to your street. Ninety-nine dollars does not cover any of that, so the money has to appear somewhere else.
Red flags to listen for on the phone
- A flat price quoted before anyone asks how many vents you have
- Unlimited vents offered for a suspiciously round, tiny number
- Pressure to book today because the offer expires tonight
- No mention of what equipment they bring
- Refusal to put the quote in writing before the visit
- Vague promises about mould without any inspection
NADCA, the industry body that sets the cleaning standard, warns homeowners about exactly this pattern. Their homeowner resources are worth five minutes before you book anyone, ours included.
What a Fair Quote Includes
Use this as your checklist. If a quote covers all of it, the duct cleaning cost you are being told is probably the one you will actually pay.
- ✅ A written quote with the vent and return count on it
- ✅ Every supply and return cleaned, not just the easy ones
- ✅ Truck-mounted or commercial vacuum with negative air on the trunk line
- ✅ Rotary brush or air whip agitation, because suction alone does not release packed debris
- ✅ Main trunk lines included
- ✅ Before and after photos, plus a written report
- ✅ Clear pricing on any add-ons, quoted before the work starts
- ✅ Proof of NADCA certification and insurance
Every BlueGuard job ends with a written report and photos. Not because it is a nice touch, but because it is the only way you can tell whether you got what you paid for. You cannot see inside your own ductwork. The report is how the duct cleaning cost becomes something you can verify.
Duct Cleaning Cost Around Ottawa Neighbourhoods
The city is not one housing stock, and that shows up in pricing.
In older Glebe and Westboro homes we often find undersized returns and ductwork that was modified two or three times over the decades. More fittings, more access points, more time. In newer Barrhaven and Riverside South builds the runs are cleaner and more predictable, but there are usually more of them, and a finished basement adds another set of vents.
Rural properties around Manotick, Carp, and Greely add drive time and sometimes a second system. None of that is a surcharge for living where you live. It is just more ductwork, or more distance. Ask any company to explain the difference and a straight answer should come easily.

How to Lower Your Duct Cleaning Cost Without Cutting Corners
There are real ways to bring the number down. Skipping the vacuum is not one of them.
Bundle the jobs you already need
Your dryer vent and furnace blower are already on the list. Doing them in the same visit costs less than two separate trips, because you are paying for one setup instead of two. That is the most reliable way to reduce your total duct cleaning cost.
Clear the access before we arrive
Move the storage bins off the basement vents. Pull the couch off the return. Ten minutes of prep can shave real time off the job, and time is what you are paying for.
Do not clean on a fixed schedule you read somewhere
Every three to five years suits most Ottawa homes. Sooner if you have pets, allergies, a recent renovation, or you just bought the place. Cleaning every year because a coupon showed up in the mail is money you did not need to spend.
Book before the fall rush
Once furnaces kick on across the city, our calendar fills fast. Earlier booking means more scheduling choice, and you are not paying a premium to squeeze into a full week.

Duct Cleaning Cost FAQ
How much is duct cleaning for an average Ottawa home?
It depends on your vent count, not your address. A typical three bedroom home with one furnace sits in the middle of our range, while homes with two systems or a finished basement land higher. Give us your vent and return count and we will quote the exact duct cleaning cost before anyone comes out.
Why are duct cleaning quotes so different between companies?
Because they are not quoting the same work. One company brings a truck-mounted vacuum and cleans every run and trunk line. Another runs a portable unit at a few vents for 30 minutes. Both call it duct cleaning. Ask what equipment comes and how many openings are included, then compare the two.
Does dryer vent cleaning cost extra?
Yes, it is a separate service with its own equipment, so it is priced separately. Bundling it with your duct cleaning appointment costs less than booking a second visit later. If your dryer takes two cycles to finish one load, get it done now rather than waiting for winter.
Is sanitizing worth adding to the price?
Sometimes, and often not. Sanitizing makes sense after confirmed mould, a rodent problem, or smoke damage. Spraying an antimicrobial into a system that was simply dusty adds to your duct cleaning cost without adding much benefit. We will tell you honestly which situation you are actually in.
How long does a full duct cleaning take?
Most Ottawa homes take two to four hours. Larger properties with two systems can run most of the day. Be cautious of anyone promising a full house in 45 minutes, because that is not enough time to properly agitate and vacuum every run, no matter how good the gear is.
Will duct cleaning lower my heating bill this winter?
It can help airflow, especially if your returns were badly blocked, but nobody should promise you a specific percentage. The honest reason to clean is air quality and system strain. Treat any energy savings as a bonus, and be skeptical of a company that sells the savings as the main pitch.
Do you charge more for older homes?
Not for age itself. Older Ottawa homes sometimes have modified ductwork, extra fittings, or awkward access, and those add time. If your century home in Hintonburg has a simple system, the duct cleaning cost is the same as anywhere else in the city. We quote the ductwork, never the postal code.
Can I just do it myself and skip the cost?
You can vacuum the first foot behind each register, and that does help with visible dust. What you cannot do is reach the trunk lines or create the negative pressure that pulls debris out instead of pushing it deeper. That equipment is the whole reason a professional duct cleaning cost exists.
The cheapest quote and the lowest duct cleaning cost are rarely the same thing. One is a number on a flyer. The other is what you pay when the work is finished. Ask for the vent count, ask what equipment is coming, and ask for the report. Any company worth hiring will answer all three without hesitating.
