Air Duct Cleaning Certification Requirements by State

Requirements for air duct cleaning work vary by state — some states license the trade, many don’t regulate it at all. This page covers all 50 states: licensing notes, demand, and typical earnings for each. The NISCR Air Duct Cleaning Certification is a professional credential that proves verified training in any state; where a license or federal credential is required, it complements — it does not replace — those requirements.

Looking for the certification itself? See the NISCR Air Duct Cleaning Certification course — online, self-paced, $199.
