The lasting repercussions of the One Big Beautiful Bill Act have begun to hit home, especially under the harsh light of surging utility costs. The cutbacks zeroed out key programs that reduce the upfront cost of energy efficient equipment. You may not have noticed, because the Bill phased them out one-by-one, each removal making it a little harder to justify the ROI cost of an energy smart upgrade or replacement.
The cuts apply to replacing an aging air conditioner with a heat pump, installing a heat-pump water heater, adding solar panels or putting a battery in the garage.
In essence, the federal government changed the math. When President Trump signed the legislation commonly called the One Big Beautiful Bill Act on July 4, 2025, much of the public conversation centered on taxes, Medicaid, immigration, the deficit and other headline issues.
Deep inside the legislation, however, was a series of provisions with much more immediate implications for homeowners, remodelers, builders and the companies that sell high-performance building products.
To be clear, these provisions weren't literally hidden. The legislation spelled them out. One section of the Senate text was even titled "Termination of Green New Deal Subsidies." And the energy provisions did receive coverage from Reuters and energy and construction trade publications.
But compared with the political battles surrounding the enormous bill, the practical implications for someone replacing a water heater or putting solar on a house were remarkably easy to miss.
Consider the Energy Efficient Home Improvement Credit, better known by its tax-code designation, Section 25C. For 2023 through 2025, homeowners could generally receive a tax credit equal to 30 percent of qualifying efficiency improvements, subject to annual limits.
That included insulation, windows, exterior doors, electrical improvements and certain heating and cooling equipment. Heat pumps and heat-pump water heaters had their own annual credit limit of as much as $2,000.
Public Law 119-21 terminated it. According to the IRS, the credit is no longer allowed for property placed in service after December 31, 2025.
To put it in perspective, that $6,000 heat-pump installation that might have generated a $2,000 federal credit in 2025 in 2026 gets no tax credit whatsoever.
Then there's Section 25D, the Residential Clean Energy Credit.
This was the big one for homeowners considering solar, battery storage, geothermal and certain other residential clean-energy systems. The credit covered 30 percent of qualifying expenditures, with no annual maximum for many installations.
Under the previous schedule, that 30 percent credit wasn't supposed to disappear in 2026. The new law accelerated its termination to the end of 2025. And there's an important wrinkle homeowners should understand: simply paying for a solar system before the deadline wasn't necessarily enough.
The IRS says an expenditure is generally treated as occurring when the original installation is completed. If installation wasn't completed until after December 31, 2025, the expenditure generally falls outside the credit.
To put this change in an ROI perspective, a qualifying $30,000 system could previously produce a $9,000 federal tax credit. That might reduce the payback period by several years. Now the buyer gets no federal help at all.
If you’re a high-performance homebuilder, you may already be wincing about this one: Section 45L provided builders with incentives for constructing qualifying high-efficiency homes.
For qualifying single-family homes, the credit included $2,500 for ENERGY STAR certification and $5,000 for homes meeting the Department of Energy's higher efficiency standard.
Well, that one’s gone too. In fact it just died a quiet death two months ago. Under the new law, qualifying homes had to be acquired by June 30, 2026.
Commercial buildings took a hit as well. The Section 179D energy-efficient commercial buildings deduction is unavailable for qualifying property when construction begins after June 30, 2026. The federal 30C incentive for qualifying EV charging infrastructure also ended for property placed in service after that date.
As I’ve written about before, the Feds also created a couple of new rebate programs. But unlike the credits they cut, these ones are extremely limited in scope, and require what is perhaps an untenable level of red tape to actually get at the money. Perhaps I sound cynical, but I wonder if that was the plan?
The federal Home Energy Rebates initiative created two major programs: HOMES, aimed at whole-house efficiency improvements, and the Home Electrification and Appliance Rebates program.
Those programs can provide substantial assistance for qualifying projects, but they're fundamentally different from 25C and 25D. They're administered through participating states, territories and Tribes, and availability varies considerably by location and program status. The Department of Energy says rebates are currently available in select jurisdictions.
It’s not that rebates and incentives don’t already exist at the state and local. They do, but it’s challenging to keep track of them already, and adding two more restrictive programs tot the rebate mix will hardly begin to solve the nation’s vast affordability crisis, or address rising utility costs. There’s an enormous patchwork of state programs, utility rebates, local incentives, financing programs and other benefits. I know, because we track it constantly with our COGNITION Smart Data portal.
For several years, the federal government offered a relatively straightforward message: improve the efficiency of your house, install certain clean-energy technologies, and Washington would help pay part of the bill.
That era has largely ended.
Now the first question before replacing HVAC equipment, adding insulation, installing solar or upgrading a water heater will involve a deep search for local and regional incentives and rebates–plus more sensitivity to installed costs. That will put pressure on installers to work harder for less and may cause homeowners to hesitate on purchasing big ticket equipment such as heat pump water heaters and heat pump HVAC. None of this is good for business, or for the future well-being of a home’s occupants.
It makes them less resilient in the face of energy shortages, more dependent on fossil fuels, and cuts the legs out from under some of the most innovative products and systems in the housing arena today.
