Before you hire
Checking an HVAC company in the Atlanta area
HVAC licenses in Georgia
HVAC contractors are licensed by the state.
Who licenses: Georgia State Board of Conditioned Air Contractors (State Construction Industry Licensing Board, Secretary of State)
License types: Conditioned Air Contractor Class I (restricted), Conditioned Air Contractor Class II (unrestricted).
Companies: Georgia requires a state conditioned air contractor license (O.C.G.A. Title 43, Chapter 14) to perform conditioned air contracting, and the board says you may not perform services until you hold an active license. Under Board rules (Ga. Comp. R. & Regs. ch. 121), Class I is restricted to systems not exceeding 175,000 BTU of heating and 60,000 BTU of cooling and Class II is unrestricted.
Local rules: Local business license and permit rules were not confirmed here.
Check a license: goals.sos.ga.gov
Search the contractor on the Secretary of State's GOALS licensee search and confirm an active Conditioned Air Class I or Class II license that covers the size of system being installed.
Federal rule: in every state, technicians who handle refrigerant must hold EPA Section 608 certification, whatever the state or city requires.
Sources: sos.ga.gov, sos.ga.gov, sos.ga.gov, rules.sos.ga.gov. Checked October 2026 from official sources. This is not legal advice.
Questions to ask
Ask every company the same questions: license number, insurance, EPA refrigerant certification, a written itemized estimate, a load calculation for new equipment, after-hours rates, who pulls the permit, and the warranty. All eight questions.
Seasonal care
Year-round care in Atlanta
Atlanta homes lean on both heating and cooling, so each system needs a check before its season: cooling in spring, heating in fall.
