How air duct cleaning pricing works
Charge a base per system
Each furnace or air handler has its own blower, plenum, and trunk lines. A $300–$500 base per system covers setup, containment, and the core cleaning before you scale for size.
Scale by vent count
A per-vent rate of $25–$45 keeps quotes fair across a 10-register condo and a 24-register two-story. Count every supply and return register, not just the ones in main rooms.
Stack high-margin add-ons
Dryer-vent cleaning and antimicrobial sanitizing add margin while the crew is already on site. Present them as line items so the customer sees the value, not just a bigger number.
| Line item | Typical rate | Notes |
|---|---|---|
| Base per HVAC system | $300 – $500 / system | Covers blower, plenum, trunk lines, setup & containment |
| Per vent / register | $25 – $45 / vent | Each supply + return register; most homes 10–20 |
| Whole-home single system | $450 – $1,000 | NADCA-cited typical range for one furnace/air handler |
| Dryer-vent cleaning (add-on) | $100 – $150 | Often bundled; fire-safety upsell |
| Antimicrobial sanitizing (add-on) | $75 – $150 / system | Fogging/treatment after cleaning |
| Per technician hour | $90 – $150 / hour | Useful as an internal sanity check on quotes |

Air duct cleaning pricing FAQ
How much does air duct cleaning cost?
Most whole-home air duct cleaning runs between $450 and $1,000 for a single HVAC system, with a national average around $400. Pricing is driven by the number of vents and HVAC systems: figure roughly $300–$500 base per system plus $25–$45 per supply and return register. Larger homes with multiple systems or heavy buildup land at the high end.
How should I price duct cleaning — per vent or per system?
Most pros use both. A base charge per HVAC system covers the blower, plenum, trunk lines, setup, and containment, then a per-vent rate scales the job to the home's actual register count. Quoting per vent alone undercharges big homes; a flat fee alone undercharges small ones. A combined base-plus-per-vent rate card keeps quotes consistent across techs.
How much should I charge per vent?
Per-vent rates typically run $25–$45 each, counting every supply and return register. On its own, per-vent pricing usually only makes sense layered on top of a per-system base so the job covers your setup time and equipment.
How much does dryer-vent cleaning cost as an add-on?
Standalone dryer-vent cleaning runs about $100–$170, but bundled onto a duct job it's commonly $100–$150. It's an easy fire-safety upsell that adds margin without much extra setup once your crew is already on site.
Why do air duct cleaning quotes vary so much?
Number of vents and HVAC systems is the biggest driver, followed by contamination level (pets, smokers, post-renovation dust, mold), duct accessibility, home size, and whether the customer adds sanitizing or dryer-vent service. Beware lowball '$99 whole-home' ads — those are usually bait that balloon on site.
