How do I check a Missouri HVAC license?
Missouri has no statewide HVAC licensing board of its own — the license numbers shown here are real, checkable out-of-state licenses. Ask the contractor for the license number and search it on the Tennessee Board for Licensing Contractors lookup (official site).
Why is one Missouri city mostly verified and another isn't?
It reflects how each listing reached us. Listings pulled straight from the license register verify at very high rates; listings that came from permit filings or public business profiles stay unverified until we can tie them to a license. A low share is a data gap, not a warning about the city.
