Clean Energy Tax Credits & Rebates available for Illinois homeowners

Illinois HVAC Tax Credit and Rebate Calculator

Illinois homeowners can still unlock valuable HVAC incentives in 2026, but the rules have changed. Federal Energy Efficient Home Improvement Credits mostly apply to systems placed in service by December 31, 2025, while new Illinois HVAC rebates and utility programs now play a bigger role for heat pump, boiler, and central AC upgrades.

The Inflation Reduction Act (IRA) was designed to help cut greenhouse gas emissions and lower energy bills by supporting high‑efficiency equipment. Today, that support shows up as:

Energy Efficient Home Improvement Tax Credit (Section 25C)

Section 25C is a federal tax credit for qualifying energy‑efficient home improvements such as air‑source heat pumps, central air conditioners, and certain furnaces. Under current law, most homeowners can only claim this credit for eligible systems that were placed in service by December 31, 2025. If you are planning a 2026 project, you will usually rely more on Illinois and utility rebates than on 25C.

Illinois Home Energy Rebates (HOMES / HEAR)

Illinois is rolling out IRA‑funded Home Energy Rebates that help reduce the upfront cost of electrification and efficiency projects. These state‑administered programs focus on energy savings and often provide the best incentives for qualifying heat pump installations, electrical upgrades, and whole‑home improvements, especially for low‑ and moderate‑income households. Availability and rebate amounts depend on income, project scope, and program funding.

Utility HVAC Rebates in Illinois

In addition to IRA rebates, Illinois utilities offer their own HVAC rebate programs for high‑efficiency equipment. Companies like ComEd and Ameren frequently provide incentives for qualifying heat pumps, high‑efficiency boilers, furnaces, smart thermostats, and more. These rebates can often be stacked with state rebates, but stacking rules vary by program.

At Eco Temp HVAC, we install a wide selection of ENERGY STAR® certified products that are commonly used on rebate‑eligible projects, including advanced heat pumps, high‑efficiency boilers, and efficient air conditioning systems. Our goal is to help Illinois homeowners lower their energy bills while taking full advantage of current HVAC tax credits and rebates.
