Duct Cleaning Cost: What a Fair Price Looks Like
Professional duct cleaning costs most homeowners between $270 and $1,000, with a typical single system home landing near $500. Pricing is usually set per vent, at $25 to $50 each, or by square footage, at roughly $0.15 to $0.40 per square foot.
What drives the duct cleaning cost
Duct cleaning cost depends on how many vents the crew has to open, how large the home is, how many separate HVAC systems it runs, and how badly the ductwork is contaminated. Cost databases disagree on the national figure more than in most trades: HomeAdvisor puts the usual range at $271 to $508 with an average near $379, while the National Air Duct Cleaners Association and the EPA cite $450 to $1,000 for an average sized home. The gap is real, not a rounding error. The lower numbers reflect basic vent and register cleaning; the higher ones reflect certified crews using truck mounted negative pressure equipment with brush agitation on the full system.
Labor is billed at roughly $90 to $125 per hour when a company quotes hourly instead of by the job. Most homes fall somewhere between $300 and $700 for one system, with additional systems adding $200 to $400 each.
Pricing by square footage and by vent count
Contractors almost always price one of two ways, since measuring the actual linear feet of ductwork inside walls is impractical.
| Home size | Typical cost at $0.15 to $0.40 per sq ft |
|---|---|
| 1,200 sq ft | $180 – $500 |
| 1,500 sq ft | $225 – $450 |
| 2,000 sq ft | $300 – $600 |
| 2,500 sq ft | $375 – $750 |
| 3,000 sq ft | $450 – $1,000 |
| Number of vents | Typical cost at $25 to $50 per vent |
|---|---|
| 8 vents | $200 – $400 |
| 12 vents | $300 – $600 |
| 16 vents | $400 – $800 |
| 20 vents | $500 – $1,000 |
Larger return grilles usually cost more than supply registers, in the range of $40 to $75 each. A flat rate quote around $500 for a typical home is not automatically a red flag; it lands close to what either method produces anyway.
Add on services and related costs
- Dryer vent cleaning: $104 to $187, averaging about $145. Worth bundling, since a lint clogged vent is a genuine fire risk.
- Sanitizing or deodorizing: $75 to $150. Note that these are antibacterial products, not antifungal, so they do not solve a mold problem.
- Video inspection: $75 to $125, sometimes included in the quote.
- Furnace cleaning: $60 to $150 per unit.
- Duct repairs: $200 to $800 when the crew finds disconnected or damaged runs.
- Confirmed mold in the system: a separate job entirely, typically adding $500 to $3,000 or more; see mold remediation cost for how that is priced.
- Pest removal and cleanup: $200 to $1,200 if rodents have been living in the ductwork.
Do you actually need it?
The EPA does not recommend routine duct cleaning on a schedule. It becomes worthwhile when there is visible mold growth inside the ducts, rodent or insect infestation, or debris heavy enough to blow dust out of the registers, and after major construction work. If the technician also flags failing equipment, weigh the cleaning against HVAC replacement cost before spending on a system near the end of its life.
Is your quote reasonable?
For a single system home of about 2,000 square feet with 10 to 15 vents, a professional quote of $400–$700 is normal, and roughly $500 is the common landing point. Check the math yourself: multiply your vent count by $25 to $50, or your square footage by $0.15 to $0.40, and see whether the bid falls inside that band. Treat coupon offers of $79 or $99 for a whole house as advertising rather than pricing; that figure does not cover a truck mounted vacuum and several hours of labor, and the gap is usually closed with add ons sold at the door. Ask in writing how many vents and how many systems are included, whether the main trunk lines and the blower compartment are cleaned, and what happens to the price if the crew finds mold or pest damage.
