Norristown Housing Stock
Census figures put the median build year in Norristown at 1955, so a typical house here has about 71 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 40.8% of occupied homes, roughly 5,400 households. The median home value is $205,100, and median household income is $65,058. We use both figures to adjust labor and pricing for this page.
Between 2020 and 2025, NOAA's Storm Events Database logged 14 hail days and 58 days with damaging thunderstorm winds in Montgomery County. The largest hail reported was 1.75 inches across. Hail flattens the thin aluminum fins on condenser coils and cuts airflow. After a big storm, take a look at the outdoor unit; homeowners insurance often covers the damage. Montgomery County also had 4 tornado days in that period.
