Dearborn Heights Housing Stock
Census figures put the median build year in Dearborn Heights at 1958, so a typical house here has about 68 years on it. Houses that old often still have duct runs sized for an old coal or oil furnace and 60- or 100-amp electrical panels. Both can add cost when new equipment goes in. About 16,000 households here own their home, 71.6% of the occupied total. Homes here have a median value of $174,900 and households a median income of $61,035. Those two numbers drive the labor adjustment in our estimate.
Wayne County had 5 hail days and 30 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 1.5 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. Wayne County also had 2 tornado days in that period.

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. A repair usually goes ahead without a permit, but the tech handling refrigerant must hold EPA 608 certification. Ask the company for its Michigan license or registration number before the visit.
Before You Hire
- Ask for the per-pound refrigerant price before any work starts.
- If the compressor is gone on an older unit, get a replacement quote before you pay for the repair.
- If you see ice, shut the system off. Running it frozen can kill the compressor.
