Brookhaven Weather and HVAC Load
In a normal year, Brookhaven racks up 2,980 heating and 1,728 cooling degree days (NOAA 1991-2020 normals). Neither season dominates in Brookhaven. That balance is a big reason heat pumps and dual-fuel systems sell well in Georgia. A normal year brings 49 nights at or below freezing and 53 days over 90°F. Snowfall averages about 1 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.

Brookhaven Housing Stock
The median Brookhaven home dates to 1992, according to the Census ACS. That makes the typical house about 34 years old. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Brookhaven has roughly 13,000 owner-occupied homes, or 53.4% of households. The median home value is $660,300, and median household income is $117,448. We use both figures to adjust labor and pricing for this page.
DeKalb County had 1 hail day and 28 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. 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 Brookhaven. 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 your gas or oil company about rebates on condensing boilers.
- Ask for a heat-loss calculation. A lot of old boilers are much bigger than the house needs.
- A combi boiler frees up space and replaces your water heater.
