Air Duct Cleaning Cost Per Square Foot: Comrehensive Pricing Guide

One of the most transparent ways pros price air dust cleaning is by square footage. Most companies charge  $0.5 to $0.40 per square foot, with the majority falling between  $0.20 and $0.35.

This method works well because it scales directly with the  size and complexity  of your system, larger homes usually cost more, but the price per square foot often drops as size increases (economies of scale).
