HVAC Replacement in Georgia
When to repair, when to replace, what a fair Georgia install costs, and how to avoid the 30%+ pricing spread between contractors.
How long it takes
Most repairs are same-day. Full system replacements take 1 day for a like-for-like swap, 2–3 days if ductwork or electrical work is needed.
Permits & inspections
Georgia requires a mechanical permit for any equipment replacement. The HVAC contractor pulls it. Permitless installs can void your homeowners insurance and the manufacturer warranty.
Mistakes that cost the most
- Buying the same size system that's currently installed (often oversized — Manual J load calc required)
- Skipping a written Manual J load calculation
- Accepting a quote without the model and SEER2 numbers in writing
- Ignoring Georgia Power and Jackson EMC rebates ($300–$750 typical)
- Going to the lowest bid without checking install reviews — bad installs kill new equipment in 3–5 years
Contractor tips
- 1Get 3 written quotes with full equipment model numbers
- 2Verify NATE-certified technicians
- 3Confirm 10-year parts AND labor warranty in writing
- 4Ask if they handle the rebate paperwork (good ones do)
- 5Insist on a startup report with refrigerant charge and static pressure readings
Financing
Manufacturer-backed financing (Carrier, Trane, Lennox) is usually legitimate 0%. Watch for contractor in-house financing — it often hides a 10–15% price premium.

Frequently asked
Repair or replace my 12-year-old system?
If the repair is over $1,200 or involves the compressor/coil, replace. Under that on a system under 12 years, repair.
What SEER2 should I buy?
16 SEER2 is the new Georgia code minimum (was 14 SEER pre-2023). Going to 18+ pays back in 4–7 years on a home you'll keep.
Heat pump or gas?
Modern variable-speed heat pumps are the lowest total cost in most of north Georgia. Gas only wins if you already have a line and run winter setpoints below 65°F.
