What Affects the Cost of Air Duct Cleaning?

Duct cleaning prices vary because homes vary. Knowing what drives the cost makes it easier to compare quotes and spot one that doesn't add up.

What usually affects the price

  • The number of supply vents and returns
  • How many HVAC systems you have
  • Home size and number of floors
  • Attic, crawl-space or closet access
  • How much buildup or construction debris there is
  • Add-ons such as coil cleaning or sanitizing
  • Parking, building rules and travel

Be careful with very low offers

The EPA warns consumers to be wary of duct cleaners who make sweeping health claims or push unnecessary services. A low advertised price may cover only a few vents, with extra charges added on site.

Questions to ask

  1. What exactly is included in the price?
  2. Are all the vents and returns covered?
  3. How will you clean them, and with what equipment?
  4. Will you show me photos of what you find?
  5. What might cost extra, and will you ask first?
