Michigan Permits, Efficiency Rules and Rebates
Michigan 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 Ann Arbor generally need a mechanical permit, and a reputable contractor will pull it for you. Ask for their Michigan 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
- A combi boiler frees up space and replaces your water heater.
