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. Many houses that age were built with hot-water or steam heat, and plenty still run cast-iron boilers and radiators. 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.

Pennsylvania Permits, Efficiency Rules and Rebates
Pennsylvania 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. Plan on a mechanical permit for most replacements in Norristown; the contractor normally pulls it. Before you sign, ask each bidder for their Pennsylvania license or registration number and proof of insurance. The federal 25C tax credit ended for equipment installed after December 31, 2025, so incentives now come mostly from utilities and state programs. Check your electric and gas utility's rebate page before you pick equipment.
Before You Hire
- For a steam system, hire a contractor who works on steam regularly.
- Ask your gas or oil company about rebates on condensing boilers.
- Ask for a heat-loss calculation. A lot of old boilers are much bigger than the house needs.
