Furnace repair cost by part.
Typical North Decatur repair pricing including parts and labor. A diagnostic fee usually applies and is often credited toward the work.
In North Decatur, Georgia, furnace repair costs are shaped by the age of the home—most were built around 1974—and the local climate, which is hot-humid with high cooling demand. Typical repair prices range from $75–$225 for a flame sensor to $1,400–$3,300+ for a heat exchanger, plus a $70–$175 diagnostic fee. Georgia requires a mechanical permit for furnace work, and while Manual J load calculations are not strictly enforced for changeouts, they are recommended for proper sizing. Given the climate, a heat pump is often a strong fit for both heating and cooling needs, and the federal 25C tax credit (30%, up to $2,000 for qualifying heat pumps) can offset upgrade costs.

With a long, hard cooling season here, stepping up the SEER2 tier pays back through lower summer bills. A pro can confirm the right size and system for your home with a load calculation.
