Sandy Springs Weather and HVAC Load
In a normal year, Sandy Springs racks up 2,980 heating and 1,728 cooling degree days (NOAA 1991-2020 normals). Neither season dominates in Sandy Springs. That balance is a big reason heat pumps and dual-fuel systems sell well in Georgia. On average, Sandy Springs gets 49 freezing nights and 53 days above 90°F per year. 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.

Sandy Springs Housing Stock
Census figures put the median build year in Sandy Springs at 1988, so a typical house here has about 38 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 50.7% of occupied homes, roughly 26,000 households. The median home value is $583,900, and median household income is $101,593. We use both figures to adjust labor and pricing for this page.
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.
When Replacement Makes Sense
- The furnace is 15 to 20 years old or more
- A repair quote runs past a third of the cost of a new unit
- Some rooms stay cold, the burner short-cycles, or the ignitor keeps failing
- Gas or electric bills keep climbing even though usage hasn't changed
What Moves the Price
- AFUE rating: a basic 80% unit vs. a 96% condensing furnace
- Condition of the existing ductwork and any changes it needs
- BTU size, which should come from a Manual J load calculation
- Single-stage, two-stage or modulating gas valve
- Permit and inspection fees, which the local building department sets
- New PVC venting if you move to a condensing model
For Sandy Springs we raised the national figures about 23%, based on local income, home values and climate-based equipment sizing. Get at least three written quotes; real bids can land outside this range.
What the Quote Should Cover
- Removing and hauling away the old furnace
- The permit and the manufacturer warranty registration
- Gas line and vent connections
- The new furnace, filter rack and thermostat wiring
- Combustion and safety tests
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). Plan on a mechanical permit for most replacements in Sandy Springs; the contractor normally pulls it. Before you sign, ask each bidder for their 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 the Manual J load calculation in writing. Oversized furnaces are the most common mistake we see.
- Look up utility rebates on 95%+ AFUE units before you buy.
- Make sure all three quotes are for the same AFUE and staging, or you can't compare them.

In spring or fall. Those are the slow months between heating and cooling season in Sandy Springs.
Is a high-efficiency furnace worth it?
