Duct Cleaning Costs in Toronto: Key Insights
- Most Toronto homeowners pay between $250 and $500 for a standard duct cleaning, with larger or dirtier systems running as high as $5,000 or more.
- Furnace cleaning is often bundled with duct cleaning: a combined service typically costs $350 to $600, less than booking each separately.
- Mould or rodent remediation adds significantly to the total: mould treatment can add $100 to $300+ depending on the extent, and rodent removal may require a separate exterminator.
- Per-vent pricing is common among Toronto contractors: a home with 18 vents will cost noticeably more than one with 10 vents, even if the homes are similar in square footage.
- Quotes advertised below $100 are often bait pricing. Expect additional charges once the technician assesses your ducts, such as per-vent add-ons or furnace cleaning, which can nearly double the final bill.

Duct Cleaning Prices in Toronto
Many homeowners in Toronto have extensive ductwork running throughout their homes. Whether you keep your house cool in the summer with central air conditioning or use a furnace to stay toasty in the winter, air ducts support maintaining a comfortable home. Keeping these systems clean matters: dirty ducts can push dust, allergen particles, and other contaminants through your vents and into the air you breathe.
Here are some typical cost ranges for common duct cleaning services in Toronto:
| Service | Typical Cost Range |
|---|---|
| Duct cleaning (standard residential) | $250 to $500 |
| Furnace cleaning | $120 to $300 |
| Combined duct and furnace cleaning | $350 to $600 |
| Per-vent add-on pricing | $9 to $15 per vent |
The following sections break down duct cleaning and furnace cleaning costs in more detail.
Duct Cleaning
Ducts circulate air throughout your home to maintain comfort year-round. Over time, they accumulate dust, mould, allergen particles, debris, and sometimes rodents. Professional duct cleaning removes these contaminants and improves indoor air quality.
In Toronto, standard duct cleaning costs between $250 and $500 depending on system size and contamination level. Larger homes or systems with heavy buildup, mould, or rodent damage will cost more. For a broader look at duct cleaning costs across Canada, see the guide to national duct cleaning costs.
Furnace Cleaning
Your furnace needs regular maintenance to run efficiently and last longer. It’s best to change filters every two to three months and to schedule a professional cleaning once a year, ideally in spring or early summer when you are not using the heating system.
Furnace cleaning in Toronto typically costs between $120 and $300, though high-efficiency furnaces with extra components like secondary heat exchangers may cost more to service. Many contractors bundle furnace cleaning with duct cleaning for a combined price of $350 to $600.
Factors That Affect Duct Cleaning Costs in Toronto
Several factors influence how much you will pay for duct cleaning in Toronto. Understanding them helps you compare quotes more accurately.
Accessibility
If your ducts do not have easy access from the basement or a utility room, reaching specific areas can take considerably more time. Older Toronto homes, semi-detached properties with narrow mechanical areas, or homes with finished basements can all add to the labour involved. The harder the access, the higher the quote is likely to be.
Custom Designed Ducts
Most Toronto homes have air ducts installed in a fairly predictable layout, but if you have a custom duct system with additional components, non-standard configurations, or features that are difficult to access, expect to pay more for added time and effort.
HVAC Mould and Mildew Removal
Standard duct cleaning may not fully address mould that has saturated parts of your HVAC system. When mould is present, contractors will check and clean components including grilles, diffusers, heat exchangers, drip pans, fans, and plenums, adding time and cost to the job. In cases of significant mould growth, you may need to bring in a specialist separately.
For a full breakdown of what mould remediation costs, see the mould remediation cost guide.
Rats and Mice
The presence of rodents in your ducts can significantly affect air quality in your home. Some duct cleaning contractors handle rodent removal themselves, while in other cases, you may need to hire a separate exterminator to remove live or dead rodents from the ductwork before cleaning can proceed. Either way, that cost will be added to your final bill.

Benefits of Duct Cleaning
Regular duct cleaning offers several practical advantages for Toronto homeowners:
- Eliminates unpleasant odours
- Improves indoor air quality
- Improves airflow efficiency
- Increases the longevity of your furnace and air cooling system
- Lowers energy bills
- Reduces allergens and irritants in the air
- Removes hazardous contaminants like mould and mildew
If a family member has airborne allergies or a breathing condition such as asthma, checking your ducts every three to four months is worth considering. Cleaning ducts yourself with a vacuum or household tools will not do the job and may cause damage. A professional inspection and cleaning once a year is the more practical approach.

How Do Pros Determine Duct Cleaning Prices in Toronto?
There are two main pay structures that duct cleaning pros use in Toronto. Generally speaking, a flat-rate system is more common, but per-vent is still quite common in Toronto.
Flat-Fee
Some contractors quote a flat fee for the entire job, covering all vents, the furnace, and standard labour in a single price. Contractors use this model after a site visit or when they have a clear picture of your system's size and condition.
Flat-fee quotes typically range from $250 to $500 for a standard residential cleaning in Toronto. This model is easier to budget for since there are no surprises based on vent count, though the quote should specify exactly what is included, such as return vents, sanitizing, and deodorizing, so you understand whether add-ons will push the final bill higher. Flat-fee quotes work best when the contractor has assessed your system beforehand and can give an accurate figure.
Per-Vent
Per-vent pricing charges a set amount for each supply or return vent cleaned, typically $9 to $15 per vent in Toronto. Contractors use this model when they cannot assess the full scope upfront: for example, if they are quoting over the phone without seeing the system. On a home with 15 vents, you can expect to pay roughly $135 to $225 plus labour and any additional services like furnace cleaning or mould treatment.
Per-vent pricing appears cheaper upfront but can climb quickly in larger homes or systems with many branches. Always ask the contractor to estimate the total vent count before agreeing to this model, so you know what you are signing up for.

FAQs: Your Questions About Duct Cleaning Costs in Toronto Answered
How often should I have my ducts cleaned in Toronto?
Most HVAC professionals recommend cleaning residential ducts every three to five years under normal conditions. If you have recently completed a renovation, moved into a newly purchased home, have pets that shed heavily, or have a household member with allergies or asthma, cleaning more frequently makes sense. Toronto homes with older ductwork or systems that have never been inspected may benefit from an initial cleaning regardless of the timeline.
Is duct cleaning covered by home insurance in Toronto?
In most cases, no. Standard home insurance policies cover sudden and accidental damage, not routine maintenance. If duct contamination results from a covered event such as water damage from a burst pipe, there may be some coverage for remediation, but this depends on your specific policy. It is worth reviewing your policy and speaking with your insurer directly if you suspect a covered event has affected your ductwork. You can find duct cleaning pros on HomeStars to assess your system and advise on what the job involves before you contact your insurer.
Does duct cleaning also include dryer vent cleaning?
Not automatically. Dryer vent cleaning is a separate service, though many Toronto contractors offer it as an add-on when they are already on site for duct cleaning. A clogged dryer vent is a fire risk and reduces drying efficiency, so it is worth asking about pricing when you book. Combining the two services in a single visit is generally more cost-effective than scheduling them separately.
What should I look for when comparing duct cleaning quotes in Toronto?
Look at what is actually included: the number of vents covered, whether the furnace is part of the scope, and whether sanitizing or deodorizing is extra. Ask about the equipment used, since a proper cleaning requires a high-powered negative-air vacuum system, not a shop vac. Check that the contractor can show proof of liability insurance. On HomeStars, you can review contractor profiles, read verified homeowner reviews, and compare ratings before reaching out, which makes it easier to sort through the options before committing.
