Alabama licenses heating and air conditioning contractors through the Board of Heating, Air Conditioning and Refrigeration Contractors. An active certification is what allows installation, service, or repair of heating and cooling equipment. Commercial refrigeration is a separate examination. Birmingham's building official permits the job in the city. Hoover and Vestavia Hills are outside that counter. Ask for the heating and air certification, not a home-builder card. This page shows which Birmingham HVAC companies AI assistants named most often across answers RecommendRadar ran and stored, how often each appeared, and the sources those answers cited.
