What is a heat pump?
A heat pump is an electric device that moves heat instead of making it.
It pulls warmth from outside air, ground, or water and pumps it inside to heat your home, and reverses to cool it. That's why it can replace both a furnace and an AC.

Why?
Moves heat, doesn't burn fuel It uses electricity to transfer heat, so it's cleaner than gas and often cheaper to run.
One unit does both jobs It heats in winter and cools in summer, replacing two separate systems.
Efficiency depends on climate Cold climates need a cold-climate model, but modern ones work well below freezing.
If you're deciding whether to install one, the cost and savings depend on your local electricity and gas prices.
Who is a heat pump right for?
Right for
- Homeowners replacing both furnace and AC
- People in mild to moderate climates
- Those wanting to cut carbon emissions
- Homes with existing ductwork
Wrong for
- Homes without ductwork and no space for mini-splits
- Very cold climates without a cold-climate model
- Renters who can't install permanent equipment
- Those on time-of-use electric rates with high peak prices
What does a heat pump cost in 2026?
| Figure | Value | Why it matters |
|---|---|---|
| Average installed cost | $5,500 to $12,000, 2026 | Replacing both furnace and AC can cost more, but you save on two systems. |
| Federal tax credit | Up to $2,000, 2026 | Applies to qualifying ENERGY STAR models; check current IRS rules. |
| Annual savings vs gas furnace | $300 to $800 a year, 2026 | Varies with local electricity and gas prices; higher in mild climates. |
| Cold-climate performance | Works down to -15°F, 2026 | Modern cold-climate models maintain heat output well below freezing. |
What's the biggest heat pump mistake?
The biggest mistake is buying a standard model in a cold climate. Standard heat pumps lose efficiency and output below freezing, so you end up relying on backup heat and your savings vanish. Instead, check the model's rated operating temperature and choose a cold-climate version if your winters drop below 20°F.
How do you decide if a heat pump is worth it?
- Check your current heating and cooling setup: what you pay per year and the age of each unit.
- Get quotes from at least three installers, asking for cold-climate models if you live in a cold area.
- Compare the total cost after rebates and tax credits against your current annual energy bills.
- Choose a heat pump if the payback period is under 10 years and you plan to stay in your home that long.

How much does a heat pump cost?
Most heat pumps run $5,500 to $12,500 installed. That's for a typical whole-home air-source unit, including labor. The big swing is ductwork: if you need new ducts, add $3,000 to $8,000.
