Dear Angie: I want to hire a reputable air duct cleaning company. Dear Barbara: Weâve seen a lot of reports from Angieâs List members in which they were quoted prices anywhere from $49 to more than $1,000 for the cost of air duct cleaning.
Your air ducts probably need cleaning if the filters or air returns are dusty and dirty or if you remove a vent cover and can see lots of dirt and debris inside the vent. The average cost for air duct cleaning service is $300-$500 for a 1500 square foot home. Professional air duct cleaners clean and disinfect the vent returns and filters, as well as use high-pressure âvacuumsâ to remove dirt and debris from the ducts themselves.
