Heat pump vs gas furnace cost (2026)
A 3-ton central AC plus gas furnace install runs about $9,000 in 2026. An equivalent air-source heat pump runs about $10,400. After the federal 25C credit (up to $2,000) and utility rebates, heat pump installs often beat gas on net cost.
Central AC + gas furnace
- ✓Cheapest install of any whole-home HVAC
- ✓Strong cold-weather heating without backup heat strips
- ✓Every HVAC contractor in the country installs it
- –Two pieces of equipment to maintain and eventually replace
- –Gas commodity exposure on operating cost
- –No federal tax credit on most baseline models
Air-source heat pump
- ✓Federal 25C credit up to $2,000
- ✓One unit handles heating and cooling
- ✓2 to 3x more heat per kWh than resistive electric
- –Backup heat strips activate below about 20°F in older models
- –Slightly higher repair cost when the inverter board fails
- –More installer training required; quality varies

Pick Furnace if
You have cheap natural gas, live in zone 6 or 7, and you're not planning to electrify the home in the next 10 years.
Pick Heat pump if
You're in zones 3-5, your electric rate is competitive, or you want to qualify for federal and state rebates that knock $2,000 to $8,000 off the install.

Will a heat pump heat my house in winter?+
Modern cold-climate heat pumps deliver 100 percent of nameplate capacity down to 5°F and 70 to 80 percent down to -10°F. In zone 5 or warmer, a standard heat pump handles winter without significant backup heat use.
How much is the federal heat pump tax credit?+
The 25C credit covers 30 percent of project cost up to $2,000 per year for qualifying heat pumps through 2032. State and utility rebates often stack on top, totaling $2,000 to $8,000 off the sticker.
Is dual fuel (heat pump plus gas backup) worth it?+
Sometimes, in zones 5 and 6. The setup uses the heat pump down to about 35°F and the furnace below. It captures most of the heat pump efficiency without the cold-climate equipment premium. Adds about $1,500 to the install.
