Furnace Replacement Cost in Savannah, Georgia

Savannah Weather and HVAC Load

Savannah logs 1,675 heating degree days and 2,596 cooling degree days in a normal year, based on the closest NOAA weather station. Cooling carries most of the load. Heating equipment gets light use, so a furnace here often outlasts the AC it's paired with. Count on roughly 21 nights below 32°F and 80 afternoons past 90°F in a typical year. For a 2,000 sq ft house, this climate points to a heating load somewhere near 35,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.

Savannah Housing Stock

Census figures put the median build year in Savannah at 1971, so a typical house here has about 55 years on it. A lot of these homes are on their second or third system by now. The ductwork is usually original, and leaky joints are common. About 26,000 households here own their home, 44.4% of the occupied total. The median home value is $225,200, and median household income is $56,782. We use both figures to adjust labor and pricing for this page.

Chatham County had 10 hail days and 40 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.

When Replacement Makes Sense

• The furnace is 15 to 20 years old or more
• Some rooms stay cold, the burner short-cycles, or the ignitor keeps failing
• A repair quote runs past a third of the cost of a new unit
• A tech found a cracked heat exchanger, or the CO detector has gone off

What Moves the Price

• Permit and inspection fees, which the local building department sets
• BTU size, which should come from a Manual J load calculation
• Single-stage, two-stage or modulating gas valve
• AFUE rating: a basic 80% unit vs. a 96% condensing furnace
• Condition of the existing ductwork and any changes it needs
• New PVC venting if you move to a condensing model

We lowered the national figures about 16% for Savannah using local income, home values and the equipment size this climate needs. Real bids can still come in outside the range, so collect three written quotes.

What the Quote Should Cover

• Removing and hauling away the old furnace
• The new furnace, filter rack and thermostat wiring
• Gas line and vent connections
• Combustion and safety tests
• The permit and the manufacturer warranty registration

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 Savannah. 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 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.
• Replace it in early fall if you can. A no-heat emergency in January costs more and leaves you fewer choices.
