How Much Does Furnace Replacement Cost in Georgia? (2026 Guide)

For most Georgia homes, a new furnace runs roughly $3,000 to $7,500 installed. Where you land depends on the furnace type, size, efficiency, and your existing ductwork. Here is how the pricing breaks down.

Average furnace replacement cost in Georgia

A standard gas furnace replacement typically falls between $3,000 and $5,500 installed. High-efficiency or larger systems, or jobs needing duct or gas-line work, can reach $6,000–$7,500 or more. Because Georgia winters are relatively mild, many homes do well with a right-sized mid-efficiency unit rather than the most expensive model.

What affects the price

• Furnace type: gas, electric, or a heat pump paired with an air handler.
• Size (BTUs): a properly sized unit for your square footage — bigger is not better.
• Efficiency (AFUE): 80% units cost less up front; 90%+ units cost more but lower your bills.
• Ductwork & venting: repairs or modifications add labor.
• Brand and warranty.

Repair or replace?

Consider replacing if your furnace is 15+ years old, needs frequent repairs, heats unevenly, drives up bills, or has a cracked heat exchanger (a safety issue). If it is newer and the fix is minor, furnace repair is usually the smarter spend.
