Illinois Permits, Efficiency Rules and Rebates
Illinois falls in the DOE's North region. New split central air conditioners must meet at least 13.4 SEER2, and heat pumps sold anywhere in the U.S. need 14.3 SEER2 and 7.5 HSPF2. Equipment replacements in Tinley Park generally need a mechanical permit, and a reputable contractor will pull it for you. Ask for their Illinois license or registration number and a certificate of insurance with the quote. The federal 25C tax credit ended for equipment installed after December 31, 2025, so incentives now come mostly from utilities and state programs. Check your electric and gas utility's rebate page before you pick equipment.
Before You Hire
- For a steam system, hire a contractor who works on steam regularly.
- Ask your gas or oil company about rebates on condensing boilers.
- Ask for a heat-loss calculation. A lot of old boilers are much bigger than the house needs.
