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