Michigan Licensing and Efficiency Rules
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. Most repairs don't need a permit. Anyone who opens the refrigerant circuit does need EPA Section 608 certification, and in Michigan the company should carry a state license or registration. Ask for both.
Before You Hire
- Keep space heaters away from curtains and bedding, and never heat the house with a gas oven.
- Ask what the emergency fee is before the truck is sent.
- Maintenance plans often put members first in line for emergency calls.
