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.
Air duct cleaning cost should fall somewhere between $400 and $1,200. For a single-zone system (one with a single furnace), expect to pay $300 to $600. For a two-zone system (one with two furnaces), costs might reach $600 to $1,200.
