Heater Exchanger
Older heater cores may be harder to find and therefore more expensive. It may make more sense to replace the entire furnace in an older system. Replacing a standard heater core costs $1,000 to $1,700. Installing a new electric furnace can cost $2,000 to $4,000.
Costs vary greatly by region (and even by zip code). To get free estimates from local contractors, please indicate yours.
