Plainfield Housing Stock
Half the homes in Plainfield were built before 1950 (Census ACS median), so the typical house is about 76 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 6,900 households here own their home, 42.4% of the occupied total. The median home value is $383,300, and median household income is $80,334. We use both figures to adjust labor and pricing for this page.
NOAA storm reports for Union County show 1 hail day and 25 days with damaging thunderstorm winds over the six years from 2020 to 2025. The largest hail reported was 1.25 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.
