Philadelphia Housing Stock
The median Philadelphia home dates to 1949, according to the Census ACS. That makes the typical house about 77 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. Philadelphia has roughly 350,000 owner-occupied homes, or 52.3% of households. With a median household income of $60,698 and a median home value of $232,400, local labor rates come out near the national middle in our model.
Philadelphia County had 4 hail days and 43 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. 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. Philadelphia County also had 2 tornado days in that period.
