Atlanta Weather and HVAC Load
NOAA's 1991-2020 climate normals put Atlanta at 2,775 heating degree days and 1,825 cooling degree days per year. Neither season dominates in Atlanta. That balance is a big reason heat pumps and dual-fuel systems sell well in Georgia. On average, Atlanta gets 52 freezing nights and 54 days above 90°F per year. Snowfall averages about 2 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 45,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.
| Heating degree days / year | 2,775 |
|---|---|
| Cooling degree days / year | 1,825 |
| Nights at or below 32°F | 52 |
| Days above 90°F | 54 |
| Average low / high | 51.5°F / 73.1°F |
Atlanta Housing Stock
Census figures put the median build year in Atlanta at 1987, so a typical house here has about 39 years on it. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Owners live in 46.3% of occupied homes, roughly 107,000 households. With a median household income of $81,938 and a median home value of $420,600, local labor rates come out above the national middle in our model.
Fulton County had 11 hail days and 52 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 1.75 inches across. Hail flattens the thin aluminum fins on condenser coils and cuts airflow. After a big storm, take a look at the outdoor unit; homeowners insurance often covers the damage. Fulton County also had 3 tornado days in that period.

Georgia Permits, Efficiency Rules and Rebates
Georgia is in the DOE's Southeast region, where new split central air conditioners need at least 14.3 SEER2 (13.8 SEER2 for systems of 45,000 BTU/h and up). Expect the contractor to pull a mechanical permit for a replacement job in Atlanta. If a bidder suggests skipping it, move on. Also ask for a Georgia license or registration number and proof of insurance. The federal 25C tax credit ended for equipment installed after December 31, 2025, so incentives now come mostly from utilities and state programs. Check your electric and gas utility's rebate page before you pick equipment.
Before You Hire
- A combi boiler frees up space and replaces your water heater.
- For a steam system, hire a contractor who works on steam regularly.
- Ask your gas or oil company about rebates on condensing boilers.
