Is a – Heat pumps are moving from niche to mainstream as efficiency improves—yet experts say the real difference comes down to climate, insulation, sizing, installation quality, and cost. With the federal tax credit expired and state incentives varying widely, homeow
A heat pump is sitting in a growing share of American homes’ future plans—but for many homeowners, the decision doesn’t start with technology. It starts with whether their house can actually make that technology work.
Heat pumps have surged in popularity partly because they do double duty: they can both heat and cool. In 2025, heat pumps accounted for 47% of cooling equipment sales. And from October 2025 to March 2026. heat pumps even outsold traditional air conditioning units for the first time. according to the Rocky Mountain Institute (RMI).
Still, deciding whether a heat pump is right for your home is less about following the trend and more about matching your home’s conditions to how heat pumps perform in the real world.
A heat pump doesn’t create heat—it moves it. In winter, it pulls heat from outside air and moves it indoors, which can work even in cold climates. In summer, it runs in reverse, moving hot air from inside the home to the outdoors.
That basic design drives a lot of expectations—and misunderstandings. Heat pump performance isn’t just about choosing a model with a good efficiency rating. Experts say it’s shaped by climate, insulation, correct installation, thermostat settings, and even how you live day to day.
Climate matters most. Heat pumps can work in any climate, but they perform much better in mild areas. As temperatures drop, efficiency falls—though heat pumps still run at higher efficiency than other HVAC types.
Insulation is another deal-breaker. Even the most modern, efficient heat pump system can’t do its job if the home leaks heat and cool air through poorly insulated walls. When insulation is weak, the heat pump has to work harder just to hold a comfortable indoor temperature.
More advanced heat pump models can help. Newer systems include technology for more precise capacity control, including communicating systems, variable-speed systems, and variable-speed compressors.
But technology can’t save a bad setup. A heat pump cannot work properly if it wasn’t installed correctly. “You have to install it correctly,” Scott Urquhart, an ARS HVAC sales and customer experience expert, said. “And if you don’t, you’re going to have problems.”
Thermostat behavior also shapes outcomes. Modern thermostats do more than set temperature. They can set timers, adjust home temperatures on the go, and recommend temperatures aimed at achieving a preferred energy footprint—features that can influence how efficiently the heat pump runs.
And then there’s the day-to-day choice homeowners make about how cool or warm they keep their homes. If someone wants a 65-degree home when the outside thermometer hits 95. the system will be forced to work harder and use more energy. On the other hand. keeping a home at 72 to 75 degrees during harsh hot weather could help the system perform better and last longer.
For households in northern climates, the biggest worry has long been whether heat pumps can handle real winter weather. Steve Wade. a senior director of operations and procurement at ARS. disputed that assumption. saying heat pump technology has advanced enough to make them a viable choice—often a more efficient one than traditional air conditioners and furnaces. Older heat pump models may not have been sufficient. but dual fuel systems—using both electricity and natural gas—can make heat pumps workable across climates.
In extreme cold, a highly efficient heat pump may still rely on supplemental heating, including gas. “Dual fuel is great,” Wade said. “They use electricity when [the temperatures are] warmer but switch to gas when they need more energy.” He tied that flexibility to heat pumps’ feasibility in cold regions such as Chicago and Milwaukee.
Even so, homeowners may misjudge what determines performance. Premium equipment doesn’t automatically guarantee lower bills. Wade said performance in cold climates depends more on proper system sizing, installation quality, and how the equipment is used. Even an expensive system can underperform if it’s not matched to the home’s insulation levels or if it’s oversized.
In warmer climates—Florida, Texas, and Arizona, for example—a heat pump can behave more like a traditional air conditioner, Wade said. It keeps indoor temperatures cool and also provides heat during the few months when it’s needed.
Yet myths persist there too. Homeowners may assume paying more upfront will always translate into meaningful energy savings. Wade said higher-priced systems don’t always deliver strong gains over mid-range options when efficiency improvements are marginal. For many homes. the bigger differentiator is whether the system is matched to the home’s cooling load and whether it’s maintained consistently.
Money is also where timing has shifted. The federal Energy Efficient Home Improvement Credit that allowed homeowners to claim a tax credit of up to $3,200 expired on December 31, 2025. That means fewer federal financial incentives exist for heat pumps.
In 2026, some states still offer tax incentives for energy-efficient systems like heat pumps. They include: New York. up to $8. 000 for a heat pump through EmPower+; Maryland. up to $15. 000 for projects through EmPower Maryland and the top energy providers in the state; Rhode Island. up to $11. 500 for qualified homeowners through Clean Heat RI; Colorado. funding for certain counties in Colorado via the HEAR program; and Wisconsin. where the HOMES project can save up to $5. 000 on energy efficiency projects. The list is described as not complete. with homeowners urged to check with their state and local utility companies for rebates. credits. and other opportunities.
Experts also warn that a heat pump can be a poor match when costs erase the long-term savings. Retrofitting can come with a hefty bill, especially if additional work is required. If cost is the main reason to avoid a heat pump. that reasoning may be grounded: a new heat pump can average around $13. 000. while new air conditioners run between $3. 000 and $15. 000—often making air conditioning more affordable than a heat pump.
Electrical upgrades can add a second bill. In older homes, ductwork and the heat pump are only part of the total installation. Outdated electrical systems may need updates, such as moving from a 100-amp electrical panel to a 200-amp panel.
Ductwork costs can also rise quickly. Not every heat pump requires ductwork—ductless mini-splits are one example—but for whole-home heating and cooling, ductwork is typically needed, and it can cost thousands of dollars.
In places where natural gas is cheap, switching to a heat pump might not save money. If electricity costs are high, homeowners could even spend more on energy. In regions with extreme cold, gas-powered systems may still be needed to combat temperatures. Even if a heat pump is more efficient overall, it may not be the right fit depending on local conditions.
Uninsulated homes lose heat more easily, which means heat pumps have to work harder. Upgrading insulation can fix that, but it can be expensive. Homeowners who don’t plan to stay in the home long-term may also find the payoff harder to justify.
There’s also the real-estate angle. Experts say heat pumps can attract buyers even if they don’t increase home value dollar for dollar. Dooley said: “If one home has a newer. high-efficiency A/C system and another home has a system that looks like it’s on its last legs. the house with the better system is more attractive. I don’t know that it raises the price of the home dollar for dollar, but it definitely increases desirability.”.
The reason heat pumps can cost so much comes back to both product design and installation complexity. Wade said heat pumps have additional components that don’t exist in traditional A/C. and the product is manufactured differently. including copper components that are more expensive and drive up costs. Installation can also raise totals through careful sizing. possible electrical upgrades. and. in some cases. ductwork modifications or supplemental systems for extreme temperatures. If needed, homeowners may also need a compatible indoor unit and thermostat.
A heat pump decision checklist offered by the experts draws the line between homes likely to benefit and those that may struggle.
A heat pump is described as a good idea if: you live in a mild climate where you don’t experience extreme heat or cold; your home is reasonably insulated; you have low electricity costs; and you want heating and cooling in one system.
It’s described as possibly beneficial if you have some insulation but your home is still drafty; installers are limited in your area so you can’t get multiple quotes; electricity costs are average; or you don’t live in a super cold climate.
A heat pump might not be ideal if you have cheap natural gas; you have high electricity costs; installation costs are too high to lead to savings; or you already have an air conditioner and furnace installed.
What looks like a simple consumer upgrade—switching to a more efficient system—turns out to be a fit test. Heat pumps are gaining ground fast, helped by improved technology and real market momentum. But the experts’ message is blunt: the better the match between the home and the system. the more likely the efficiency story holds up once the project is finished.

So basically if your house is old it won’t work? Cool.
I don’t get it, they said it heats and cools but it “doesn’t create heat”?? That sounds like a scam word game. Also if the tax credit is expired then who is affording these anyway.
My cousin put one in and said it made his electric bill go up, but the article is like “it’s about insulation and sizing,” which… yeah, that’s homeowner roulette. If they install it wrong then it’s not even the same technology. Doesn’t help that incentives vary by state either, like why make it complicated.
Heat pumps “outsold” AC?? I feel like AC sales are just getting bundled into “cooling equipment” or something. Also climate, insulation, installation… so it’s never just buy the unit and be done. My buddy in a place with harsh winters told me they don’t work once it gets too cold, but then they say it’s mainstream now so idk what to believe.
