Heat pump vs AC: a heat pump cools exactly like a central air conditioner but can also heat your home, and in Trane’s 2026 lineup it costs about $1,250 to $2,000 more than the matching AC. That premium usually pays off if you heat with electric resistance, propane or oil, or if your furnace is near the end of its life. If you have cheap natural gas and a good furnace, however, a standard AC can still be the better value.
Below, we compare prices, efficiency standards, heating savings and lifespan, and we show when upgrading from an AC to a heat pump makes sense. Information checked on November 4, 2026.
Heat pump vs AC at a glance
| Central AC | Heat pump | |
|---|---|---|
| Cools your home | Yes | Yes, the same way |
| Heats your home | No | Yes, by moving heat indoors |
| Federal minimum efficiency (split system) | 13.4 SEER2 in the North; 14.3 SEER2 in the South (under 45,000 Btu/h) | 14.3 SEER2 and 7.5 HSPF2 nationwide |
| Typical installed cost (HomeGuide) | $5,300–$10,500 | $8,000–$15,000 |
| Lifespan (HomeGuide) | 15–20 years | 10–20 years |
| HEEHR (formerly HEAR) rebate eligible | No | Yes, where launched, when replacing electric equipment |
Price difference: heat pump vs AC
Comparing the same brand and tier gives the clearest picture. In Trane’s 2026 replacement cost guide, each heat pump line costs more than the matching AC line, but the gap is fairly small.
| Trane line | Central AC | Heat pump | Difference |
|---|---|---|---|
| Choice | $6,568–$8,544 | $8,313–$10,289 | About $1,745 |
| Priority | $8,573–$10,671 | $9,921–$12,648 | About $1,350–$1,980 |
| Premier | $11,525–$13,669 | $12,778–$15,608 | About $1,250–$1,940 |
Other sources show a similar pattern. HomeGuide, for instance, lists $5,300 to $10,500 for central AC and $8,000 to $15,000 for an air-source heat pump. Interestingly, This Old House’s 2026 homeowner survey found nearly identical averages: $8,460 for central air and $8,007 for an air-source heat pump.
What you get for the extra cost
The main benefit is heat. At the August 2026 U.S. average electricity price, a heat pump rated at the federal minimum of 7.5 HSPF2 delivers heat for about $24 per million BTU, by our calculation. By comparison, an electric furnace or baseboard heat costs about $53, propane in a 95% furnace about $31 and heating oil in an 85% furnace about $53. As a result, a heat pump typically cuts heating bills sharply in homes that use those fuels.
With natural gas, on the other hand, the math is closer: a 95% gas furnace costs about $14 per million BTU at average prices. Our guide to heat pump vs furnace breaks this down by region, and dual fuel vs heat pump explains how to use both.
When to upgrade from an AC to a heat pump
- You heat with electric resistance, propane or oil: in that case, the heating savings are usually large.
- Your furnace is old too: a heat pump can cover most or all of your heating, so you may avoid replacing the furnace right away.
- Your state offers HEEHR rebates: the federal program (formerly HEAR) pays up to $8,000 for a heat pump for income-qualified households, while standard ACs don’t qualify. Since May 29, 2026, though, the heat pump must replace existing electric equipment.
- You want backup flexibility: also, a heat pump can work with your existing gas furnace as a dual-fuel system.
When a standard AC still makes sense
- You have cheap natural gas and a furnace that’s less than about 10 years old.
- Electricity is expensive where you live, so heat pump heating would cost more than gas.
- Your budget is tight, and the AC alone is the urgent replacement.
Either way, the size matters as much as the type. See what size AC you need, and compare installed prices in our AC replacement cost guide and heat pump cost guide.

Heat pump vs AC FAQ
Does a heat pump cool as well as an AC?
Yes. In cooling mode, a heat pump works the same way as a central AC, moving heat from inside your home to the outdoor unit.
Does a heat pump cost more to run in summer?
Not inherently. Cooling costs depend on the SEER2 rating, so compare models with similar ratings; the federal minimum for split heat pumps is 14.3 SEER2.
Can I add a heat pump to my existing furnace?
Often, yes, as a dual-fuel system. However, the new outdoor unit needs a matching indoor coil, and the furnace must be approved for it by the manufacturer.
Is there still a tax credit for heat pumps?
No. The IRS says the Energy Efficient Home Improvement Credit covers only improvements made through December 31, 2025. Rebates, however, may still be available through your utility or, for electric-to-electric upgrades, the federal HEEHR program (formerly HEAR).
