This homeowner cut her heating bill in half — and got a $1,200 tax credit

Megan Moritz bought her dream house in 2019.

However, the 1,400-square-foot home, in the Arlington Heights suburb northwest of Chicago, was built in the 1930s and lacked insulation — leading to heating bills that were “very high,” said Moritz, 48.

The first-time homeowner opted to pay about $5,700 for a series of projects last year to make her home more energy-efficient. She added insulation to the walls, and sealed gaps in ductwork connected to her furnace to prevent air leaks.

Moritz shaved her gas heating bill by half or more during the winter months, and her home is now “delightfully toasty,” she said. She slashed her bill to $102 in December 2024 from $311 two years earlier, records show. In January 2025, her bill was $116, down from $288 in 2023.

Moritz also received a $1,200 federal tax break when she filed her tax return this year, according to records reviewed by CNBC. She’s among millions of homeowners who claim a tax credit each year for retrofits tied to energy efficiency.

“The biggest perk to me, honestly, was not freezing my butt off,” said Moritz, who works for a global professional association. “Then it was the monthly bill going down as much as it did.”

“The tax credit was a nice little perk, the cherry on top,” she said.

The tax break, however, may not be available for much longer.

Republicans have signaled an intent to put the tax break and other consumer financial incentives linked to the Inflation Reduction Act on the chopping block to raise money for a multi-trillion-dollar package of tax cuts being negotiated on Capitol Hill.

The tax break — the energy efficient home improvement credit, also known as the 25C credit — is worth up to 30% of the cost of a qualifying project.

Taxpayers can claim up to $3,200 per year on their tax returns, with the overall dollar amount tied to specific projects.

They can get up to $2,000 for installing a heat pump, heat pump water heater or biomass stove/boiler, and another $1,200 for other additions like efficient air conditioners, efficient windows and doors, insulation and air sealing.

About 2.3 million taxpayers claimed the credit on their 2023 tax returns, according to Internal Revenue Service data.

The average family claimed about $880, according to the Treasury Department.
