According to the Environmental Protection Agency, cleaning a typical house’s whole system might cost between $450 and $1,000. A variety of factors, however, impact cost and time estimates:
• the kind of ductwork • the size of the system • access to the system • the number of crew members required • the amount of pollution • environmental considerations
Be careful of advertisements that claim “whole home reductions” at ridiculously cheap prices. Many just include the main ducts and demand additional fees for the air handler, blower fans, coils, registers, and cutting access, among other things. Many of these companies then demand high fees once they arrive.
