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.
The fact of the matter is this: the average air duct cleaning for most homes costs between $300 and $500, with the price affected by factors like the size of the home, the number of ducts and their configuration. According to Blue Book International, the average price for air duct cleaning is $35 per vent.
