Number of vents and returns
One of the strongest everyday pricing inputs. Count registers before requesting a quote.
2026 cost estimator
Estimate your air duct cleaning cost.
Built around the factors contractors actually price: vent count, HVAC systems, contamination, local market, and real add-ons.
Start here
A realistic range without assuming the expensive version of every job.
Enter your ZIP if you want the local pricing layer applied automatically. Your actual vent count and system count still drive the result.
ZIP pricing adjusts the local market component while your actual vent and system counts still drive the estimate.

Count the floor, wall, and ceiling registers throughout the home.

Contamination
Heavy means renovation dust, smoke residue, substantial pet debris, or other unusual buildup.
Add-ons
How to use the result
Use the range to evaluate quotes, not to force every contractor into one number. Ask what is included, how many vents and returns are counted, whether trunk lines are included, and whether the quote includes equipment cleaning beyond the ducts.
Quick price reference
Common line-item pricing.

What moves a quote
The factors that matter most.
Number of HVAC systems
A second system adds another duct network and setup, so the increase can be significant.
Duct material and layout
Open rigid ductwork is usually easier to access than flex duct in a tight attic or crawlspace.
Cleaning method
A more complete source-removal process can require more equipment and labor than cleaning visible openings.
Contamination level
Renovation dust, smoke residue, pest debris, and unusually heavy buildup can add labor.
Access and travel
Roof terminations, upper floors, crawlspaces, and long travel can add difficulty or trip charges.
