Trenton Housing Stock
Census figures put the median build year in Trenton at 1950, so a typical house here has about 76 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. Owners live in 35.9% of occupied homes, roughly 12,000 households. The median home value is $122,500, and median household income is $47,102. We use both figures to adjust labor and pricing for this page.
Mercer County had 6 hail days and 33 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. Mercer County also had 5 tornado days in that period.
