Atlanta, Georgia.

What license do I need to work as an HVAC contractor in Atlanta, GA?

You need a Georgia Construction Industry Licensing Board (GCILB) license. The three classes are: Class A (unlimited scope), Class B (projects up to $50,000), and Class C (projects up to $10,000). All require 4 years documented HVAC work experience, passing scores on the Georgia Construction Law & HVAC Business and Law exam and the HVAC Trade exam (both 70% minimum), and 12 CE hours every two years. Most Atlanta commercial work requires Class A. Apply through GCILB; exams are administered by PSI. Timeline: 2-3 months if experience is documented cleanly.

Do I need a permit for every HVAC job in Atlanta?

No, not every job. Mechanical permits are required for all installations, replacements, and significant repairs (including ductwork modifications) in City of Atlanta. Routine maintenance, service calls, and refrigerant recharges do not require permits. For jobs that require permits, submit to Atlanta Department of City Planning; residential replacements typically cost $75-$150 for permit fees. Inspections are mandatory—rough inspection before enclosure, final before occupancy. Plan 3-5 business days for inspection scheduling. Commercial projects over 10 tons may require engineered drawings and plan review, adding 5-10 days.

What is the typical cost to replace an AC unit in Atlanta?

Residential AC replacement for a 3-5 ton system runs $5,500 to $9,200 installed in Atlanta. Costs depend on unit efficiency (SEER rating), brand, ductwork condition, and labor complexity. Labor comprises 30-40% of the cost. High-efficiency units (SEER 16+) run higher; standard SEER 13-14 units are lower end. Commercial units vary widely by tonnage and application. Furnace replacement averages $3,800 to $6,500. These figures reflect 2024 Atlanta market rates and include materials, labor, and permits.

What insurance do I need to operate as an HVAC contractor in Georgia?

Georgia requires a minimum $300,000 general liability insurance per occurrence for HVAC contractors holding a GCILB license. If you have employees, workers' compensation insurance is mandatory (statutory minimums vary by payroll). Most Atlanta commercial clients contractually require $1,000,000 general liability coverage. EPA-regulated refrigerant handling and business property coverage are strongly recommended. Budget $1,200-$2,500 annually for combined GL and WC if you have employees. Verify coverage limits with your agent—Atlanta commercial jobs often have stricter requirements.

When is peak season for HVAC work in Atlanta, and how much do contractors make?

Peak season is May through September (summer cooling demand). Secondary peak is February through March (spring prep and heating season). Winter (November-January) is slower. Median hourly wage for HVAC technicians in Georgia is $27.44/hr ($57,075 annually per BLS data), but contractor earnings vary. Service calls and replacements command higher margins than labor-only work. During peak season, a full crew (3-4 techs) can gross $5,000-$8,000 weekly before overhead. Winter slower seasons average $2,500-$4,000 weekly. Revenue depends on crew size, pricing, and service vs. installation mix. Maintenance contracts provide steady off-season revenue.
