Dearborn Housing Stock
Half the homes in Dearborn were built before 1952 (Census ACS median), so the typical house is about 74 years old. 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 25,000 households here own their home, 68.2% of the occupied total. The median home value is $205,900, and median household income is $65,192. We use both figures to adjust labor and pricing for this page.
NOAA storm reports for Wayne County show 5 hail days and 30 days with damaging thunderstorm winds over the six years from 2020 to 2025. 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.
