The Federal Heat Pump Tax Credit in 2026: What Changed

By the Modern Air team · Updated September 14, 2026 · 8 min read

What happened to the federal heat pump tax credit in 2026? The 25C credit expired after 2025. The honest status for South Bay homeowners.

This post lays out exactly where things stand, honestly, so you can plan with accurate information rather than outdated headlines.

We are an HVAC company, not a tax firm, so treat this as a plain-English overview and confirm specifics with a tax professional. But here is the situation as clearly as we can put it.

What the credit was

The credit at the center of this is the Energy Efficient Home Improvement Credit, known by its tax-code section number, 25C. For qualifying heat pumps, it provided a credit equal to 30% of the cost, capped at $2,000 per year.

To qualify, a heat pump generally had to meet the highest efficiency tier set by the Consortium for Energy Efficiency (CEE). This was a genuinely meaningful incentive. On a typical heat pump project, the $2,000 maximum took a real bite out of the upfront cost, and it was one of the main reasons heat pumps became more attractive to homeowners over the past few years.

What changed for 2026

Here is the key fact, straight from the IRS: the 25C credit applied to qualified property placed in service before December 31, 2025. According to the IRS, the credit does not apply to installations in 2026.

In other words, the window for claiming this particular federal credit on a new heat pump has closed. If you are installing a heat pump in 2026, you should not plan your budget around receiving the 30%/$2,000 federal 25C credit, because it is no longer available for current-year installations.

We are stating this plainly because there is a lot of stale information online. Older articles, calculators, and even some manufacturer pages still describe the credit as if it runs indefinitely. It does not. Always check the current IRS guidance, and do not let an outdated web page set your expectations.

If you installed in 2025

There is a silver lining for some homeowners. If your qualifying heat pump was placed in service on or before December 31, 2025, you may still be able to claim the 25C credit on your 2025 tax return. “Placed in service” generally means the system was installed and ready for use, not just purchased.

There were also documentation requirements in 2025, including reporting a manufacturer’s qualified product identification number. If you installed last year, gather your paperwork and talk to a tax professional about claiming it correctly. Do not leave money on the table if you qualify.

What is still available to help

The end of the federal 25C credit does not mean you are on your own. Several other paths can help make a heat pump affordable:

• California and utility programs. California has its own incentive landscape, and utility and state programs for heat pumps can change year to year. These are separate from the federal tax credit and may still offer support in 2026. It is worth checking current California and local utility programs when you plan your project. Our companion article on California heat pump rebates goes deeper on the state side.
• Financing. Spreading the cost of a heat pump over manageable monthly payments can make the upgrade work even without the federal credit, especially when the energy savings offset part of the payment. See our financing options.
• The energy savings themselves. This is the part that does not depend on any program. A heat pump is one of the most efficient ways to heat a home.

The Department of Energy notes that today’s heat pumps can use up to 50% less electricity for heating than electric resistance heating such as furnaces and baseboard heaters. Those savings show up on every bill, for the life of the system, credit or no credit.

Does a heat pump still make sense in 2026?

For many South Bay homes, yes. The case for a heat pump was never only about the tax credit. Our mild climate is ideal for heat pump operation, a single system handles both heating and cooling, and the efficiency advantage over older furnaces and electric resistance heat is substantial and ongoing. California’s broader push toward electrification also points in this direction for the long term.

The honest framing is this: the federal 25C credit made an already-good investment a bit cheaper up front. With that credit gone for 2026 installations, the upfront math is less generous, but the fundamental value of a heat pump, efficiency, dual heating and cooling, and a good fit for our climate, has not changed.

Whether it is the right move now depends on your current system’s condition, your budget, and whether any state or utility incentives apply to your project. Our heat pump installation page covers how we size and spec a system.

Why so much online information is wrong right now

If you search for the heat pump tax credit, you will find a confusing mix of pages. Some say it runs through 2032, some give the 30%/$2,000 figures with no end date, and some are accurate. Here is why the confusion exists, so you can read past it.

When the credit was extended a few years ago, it was originally written to run for many years, and a great deal of content was published describing it on those terms. That content is still online, still ranking, and still being copied into new articles and savings calculators. It describes the law as it was, not as it now stands. The earlier end date means a lot of that material is simply out of date for 2026 installations.

The practical lesson is to trust the primary source. The IRS page on the Energy Efficient Home Improvement Credit is the authoritative reference, and it states the credit applied to property placed in service before December 31, 2025. When a blog, a contractor’s flyer, or a rebate calculator tells you a different story for a 2026 install, weigh it against that primary source.

We would rather tell you the disappointing-but-accurate version now than have you discover at tax time that a credit you counted on does not apply. Plan with current numbers, not last year’s headlines. Modern Air, on how it communicates incentive changes
