Heat Pump vs Central AC: Compare Total Costs

Answer: Choose a heat pump when the furnace is also near replacement, the home can support the equipment, and modeled heating savings justify the added installed cost. Choose central AC when the furnace is sound and fuel is economical. For 2026 installations, compare bids without a federal 25C credit.

This comparison is for a homeowner replacing central air who must decide whether to keep a separate furnace or move some or all heating to a heat pump. It is not a universal recommendation. Climate, electricity and fuel prices, duct condition, electrical capacity, equipment performance at the local winter design temperature, and installer quality can change the answer.

The IRS says the Energy Efficient Home Improvement Credit under Section 25C is not allowed for property placed in service after December 31, 2025. State, local, manufacturer, and utility incentives may still exist, but they vary by address and program. Ask each bidder to list every incentive separately and verify it with the program administrator before treating it as money saved.
