Non-business energy property credit
The non-business energy property credit can reduce your tax bill for some of the costs you incur to make energy-efficient improvements to your home. Your tax credit equals 10 percent of those costs, with a maximum credit of $500.
Eligible costs include the purchase price and installation charges for efficient heating and air conditioning systems, water heaters and stoves that run on biomass fuel. You may also claim a credit for the purchase of energy-efficient doors, windows, skylights, certain roofs and the cost of increasing insulation in the home. However, you cannot include the installation costs for this equipment in the credit.
