Do I need a permit for hvac replacement or installation in Brunswick?

Yes. In Georgia, hvac replacement or installation generally requires a permit, and Brunswick is no exception.

Replacing a furnace, air handler, or condenser generally requires a mechanical permit in Georgia jurisdictions even when it is a like-for-like swap. Gas or electrical connections may require coordinated inspections; use a licensed mechanical contractor where required. Glynn County's own permitting office is the Glynn County Building Permitting and Inspections office, reachable on 912-554-7456 at https://www.glynncounty.org/government/departments/building-permitting-inspections. It issues permits for the unincorporated county. If your city does not run its own building department, and many smaller Georgia municipalities do not, this is the office that will handle the job. A change-out is normally a mechanical permit, and gas fired equipment usually adds a second permit and a pressure test. Ordinance 1084 Sec. 12-28 exempts only portable heating, cooling, and ventilation units, small self-contained refrigeration units, and part replacements that do not alter the equipment's approval. Replacing an HVAC system needs a mechanical permit, which is $60 for residential work. The contractor's permit and certification form for mechanical, electrical, gas, or plumbing work must be filed before the first inspection, or a $50 penalty applies (Ordinance 1084, Sec. 12-40). HVAC contractors pulling Brunswick permits must have a city business tax certificate or a valid Georgia business license and a Georgia state license on file with Planning, Development and Codes (Sec. 12-54).
