Between 2020 and 2025, NOAA's Storm Events Database logged 7 hail days and 34 days with damaging thunderstorm winds in Macomb County. The largest hail reported was 1.75 inches across. Storms here are more likely to cause power surges than coil damage, so a surge protector on the outdoor unit is worth the small cost. Macomb County also had 2 tornado days in that period.

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. Plan on a mechanical permit for most replacements in Warren; the contractor normally pulls it. Before you sign, ask each bidder for their Michigan license or registration number and proof of insurance. 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
- Rinse the indoor filters once a month during heavy use.
- If winter nights regularly drop below 10°F, pay for a cold-climate model.
- Most mini-splits qualify for utility heat pump rebates, so check before you buy.
