How do I check an Ohio HVAC license?
Ask the contractor for the license number and search it on the Ohio CILB lookup (official site). Every verified profile on AirProHQ links straight to it, with the number already on the page.
Why is one Ohio 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.
