Owners of single-family homes, two-flats and individually-metered condos, apartments and townhomes can get rebates on a wide range of energy-saving improvements to their homes. The program offers HVAC, water heater and weatherization rebates.

New equipment must be installed and old equipment removed. Only new products that meet the energy-efficiency specifications listed on the residential application qualify. Rebates may not exceed the project cost.

Complete terms and conditions can be found on the rebate applications. The HVAC and Water Heater Application is available here, but you must contact an Illinois Home Performance certified contractor for the Weatherization Application (attic insulation, air sealing and duct sealing). To speak with a program representative and learn more about available rebates, call 855-849-8928.
