Heat Pump vs Gas Heating: A Cost Comparison

How heat pumps compare to gas furnaces

A gas furnace burns natural gas to produce heat — straightforward and effective. A heat pump works differently: it moves heat from outside air into your home using a refrigerant cycle, similar to an air conditioner running in reverse. Because it moves heat rather than generating it, a heat pump can deliver 2-4 times more heating energy than the electricity it consumes.

That efficiency advantage means a heat pump often costs less to run than a gas furnace, even though electricity is more expensive per unit than gas. The key metric is the coefficient of performance (COP) — a COP of 3 means you get 3 kWh of heat for every 1 kWh of electricity. Modern cold-climate heat pumps maintain a COP above 2 even at temperatures below 0 degrees F. Use our Heat Pump Cost Calculator to compare running costs for your specific climate and energy rates.

Installation costs

A new gas furnace typically costs $3,000-7,000 installed. A heat pump system (which provides both heating and cooling) runs $4,000-12,000 depending on the type and size. While the upfront cost is higher, a heat pump replaces both your furnace and your air conditioner — so the comparison should account for both systems.

• Gas furnace + central AC: $5,000-12,000 combined
• Heat pump (ducted): $4,000-10,000 for heating and cooling in one system
• Mini-split heat pump: $3,000-8,000 per zone, ideal for room-by-room control

Climate considerations

Heat pumps work in every climate, but their efficiency advantage is largest in moderate climates where winter temperatures rarely drop below 20 degrees F. In colder regions, modern cold-climate heat pumps (sometimes called hyper-heat models) still outperform gas furnaces on efficiency, but the gap narrows as temperatures fall.

In the coldest climates, some homeowners opt for a dual-fuel system: a heat pump handles heating most of the year, and a gas furnace kicks in during the coldest days when the heat pump would struggle to keep up. This gives you the efficiency of a heat pump for 80-90% of the heating season with the reliability of gas as a backstop. Check your heating costs with the Home Energy Calculator to see how much you currently spend on heating versus other categories.

Incentives and rebates

Heat pumps qualify for significant federal and state incentives. The federal energy efficiency tax credit covers 30% of the cost (up to $2,000) for qualifying heat pump installations. Many states and utilities offer additional rebates of $500-5,000 depending on the system type and your income level.

These incentives can close the upfront cost gap with a gas furnace entirely, making the lower running costs pure savings from day one.
