HVAC Cleaning Cost in Ontario: What It Includes
HVAC cleaning costs $399 at Vacu-Man for a typical Ontario home up to about 2,200 square feet, covering the ducts, furnace blower, and A-coil with the first 10 registers included. Additional vents are $10 plus HST each. Pricing follows system size — vent count, number of furnaces, and add-ons — not a flat rate, and never a $99 whole-home offer.
“HVAC cleaning,” “furnace cleaning,” and “duct cleaning” get used interchangeably by companies that mean very different things by them. Here is what a genuine whole-system cleaning includes, what it costs in Ontario, and which variables actually move the number.
What Does HVAC Cleaning Cost in Ontario?
Honest pricing is based on the size of your system: how many vents, how many furnaces, and whether add-ons are bundled into the same visit. These are Vacu-Man’s published residential rates:
| Service | Price |
|---|---|
| Full HVAC cleaning — ducts, furnace blower and A-coil (home up to ~2,200 sq ft, first 10 registers) | $399 |
| Each additional register or vent | $10 + HST |
| Standard 16x25x1 furnace filter supplied | $10 + HST |
| Dryer vent cleaning added to the same visit | $99 – $325 |
| Second furnace in the same home | Quoted — effectively a second system |
| Commercial and institutional systems | Free on-site estimate |

What Changes the Price of HVAC Cleaning?
Four variables account for nearly every difference between one quote and another:
- Vent count. The single biggest factor. A large home can carry 25 or more registers, and at $10 per additional vent the total scales predictably rather than jumping.
- Number of systems. A home with two furnaces is effectively two cleaning jobs sharing one visit.
- Add-ons. Dryer vent cleaning drops to $99–$325 when booked with a furnace and duct cleaning instead of as a standalone visit.
- Access. Finished basements, tight mechanical rooms, and roof-exhausted vents add working time.
What should not change the price is the crew arriving and discovering problems. A company that publishes its rates has nothing to renegotiate at your door — which is exactly why ours are public.
Why $99 HVAC Cleaning Offers Are Not Real Prices
A $99 whole-home HVAC cleaning does not exist as a properly equipped service — the truck, insurance, licensed labour, and hours involved cost more than that before anyone makes a dollar. The $99 figure is a door-opener: once inside, the crew “finds” mould, upsells sanitizing treatments, and the invoice lands at three to six times the advertised number. We wrote a full breakdown of the $99 duct cleaning scam and how to spot it before booking.
What HVAC Cleaning Includes
A full HVAC cleaning covers the complete air path: supply and return ducts, main trunk lines, floor and wall registers, the furnace blower fan, and the A-coil. Companies that clean “ducts only” — skipping the blower and coil — leave the system’s dirtiest components untouched, which is why two quotes for the “same” job can differ by hundreds of dollars.
Our air duct cleaning process page shows each stage, and the furnace cleaning page covers the components inside the cabinet. Truck-mounted vacuums running 8,000 to 18,000 CFM do the actual work — equipment a portable shop-vac operation cannot match.
HVAC Cleaning vs Duct Cleaning: Is There a Difference?
The terms overlap. “Duct cleaning” strictly means the ductwork; “HVAC cleaning” implies the whole system including furnace components. At Vacu-Man they are the same service — we clean through to the furnace every time, because cleaning ducts without the blower fan is like changing your oil but leaving the filter in.
If you are comparing quotes across the province rather than pricing a single system, our Ontario duct cleaning cost guide covers the wider market ranges and what a legitimate quote looks like.
How Often Is HVAC Cleaning Needed?
Every 3 to 5 years for most homes — sooner after renovations, with shedding pets, or in a newly purchased home whose history you do not know. The EPA’s guidance is that visible evidence should drive the timing: mould, pests, or heavy debris warrant cleaning regardless of the calendar. Full detail in our guide to how often air ducts should be cleaned.
At $399 every four years, a whole-system cleaning works out to roughly $100 per year of ownership — less than most single furnace service calls.

Frequently Asked Questions
How much does it cost to clean an HVAC system?
For a typical Ontario home, $399 covers a full system cleaning — ducts, furnace blower, and A-coil, with the first 10 registers included and $10 plus HST for each additional vent. Larger homes, second furnaces, and add-on services adjust the total. Commercial systems are quoted after a free on-site estimate.
How much does it cost to clean a furnace?
Furnace cleaning is not billed separately at Vacu-Man — the blower fan, A-coil, and cabinet interior are cleaned as part of the $399 furnace and duct cleaning. Companies that quote furnace cleaning as its own service call are usually pricing a narrower job than a full system clean.
Does HVAC cleaning include the air conditioner?
The indoor side, yes — the A-coil sits in the air path and is cleaned as part of every full system cleaning. The outdoor condenser unit is HVAC-service territory rather than duct cleaning, though clearing debris from around it yourself takes minutes and helps efficiency.
How long does HVAC cleaning take?
Most homes take 2 to 3 hours. Larger homes, systems with more than 20 vents, two furnaces, or an added dryer vent cleaning extend that. You will walk the system with the technician at the start and do not need to supervise afterward.
Is HVAC cleaning worth the cost?
When it genuinely includes the blower and coil, yes: it restores airflow the system has been fighting, removes the debris that recirculates as household dust, and lets a technician see components you never will. It is not worth paying for shortly after a previous cleaning, or from any company that will not tell you exactly what is included.
