Stonecrest Weather and HVAC Load
NOAA's 1991-2020 climate normals put Stonecrest at 2,908 heating degree days and 1,843 cooling degree days per year. Neither season dominates in Stonecrest. That balance is a big reason heat pumps and dual-fuel systems sell well in Georgia. Count on roughly 68 nights below 32°F and 74 afternoons past 90°F in a typical year. 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 | 2,908 |
|---|---|
| Cooling degree days / year | 1,843 |
| Nights at or below 32°F | 68 |
| Days above 90°F | 74 |
| Average low / high | 49.7°F / 74.3°F |
Stonecrest Housing Stock
Half the homes in Stonecrest were built before 1999 (Census ACS median), so the typical house is about 27 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Owners live in 53.2% of occupied homes, roughly 11,000 households. The median home value is $223,100, and median household income is $62,939. We use both figures to adjust labor and pricing for this page.
Between 2020 and 2025, NOAA's Storm Events Database logged 1 hail day and 28 days with damaging thunderstorm winds in DeKalb County. The largest hail reported was 1.75 inches across. Storms here are more likely to cause power surges than coil damage, so a surge protector on the outdoor unit is worth the small cost. DeKalb 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 Stonecrest. 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
- Ask for a heat-loss calculation. A lot of old boilers are much bigger than the house needs.
- For a steam system, hire a contractor who works on steam regularly.
- A combi boiler frees up space and replaces your water heater.
