Permit likely required

Most likely yes. Hvac replacement or installation usually requires a permit in Alabama. Confirm the specifics with Unincorporated Dallas County.

A new or relocated system, or one that burns gas, goes beyond a like for like change out and is not covered by replacement exemptions. Gas piping and venting normally require their own permit and a pressure test, and a relocated system usually triggers new duct, condensate, and electrical disconnect requirements. Only a person whose responsible person is a state-certified heating and air contractor may obtain permits for or perform that contracting work (Code of Ala. 34-31-24). An owner may do heating and air installation, service, or repair on a building that is their own real property (Ala. Admin. Code r. 440-X-3-.05), but local permits still apply. Anyone testing and verifying duct air tightness must register with the Board of Heating, Air Conditioning and Refrigeration Contractors.
