AC and Furnace Cost Calculator

How much does an AC and furnace cost together?

Replacing a central air conditioner and gas furnace together costs more than either alone, but sharing one installation visit and ductwork often makes it cheaper than two separate jobs. Your price depends on AC tonnage, furnace efficiency, your state, and whether new ductwork is needed.

Frequently asked questions

Should I replace my AC and furnace at the same time?

If both are near the end of their life, replacing them together saves on labor and ensures the two units are matched for efficiency. If only one has failed and the other is newer, replacing just the failed unit may be the better value.
