Cleaning a typical house’s whole system might cost between $450 and $1,000, according to the Environmental Protection Agency. However, a number of factors influence cost and time estimates:
• the kind of ductwork
• the size of the system
• access to the system
• the number of crew members necessary
• the quantity of pollution
Be wary of adverts that offer “whole home discounts” at absurdly low costs. Many companies just provide the main ducts and charge extra for the air handler, blower fans, coils, registers, and cutting access, among other things. When they arrive, many of these firms demand exorbitant costs.
