Portland Housing Stock
Half the homes in Portland were built before 1946 (Census ACS median), so the typical house is about 80 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 15,000 households here own their home, 46.7% of the occupied total. With a median household income of $76,174 and a median home value of $452,600, local labor rates come out near the national middle in our model.
NOAA storm reports for Cumberland County show 5 hail days and 24 days with damaging thunderstorm winds over the six years from 2020 to 2025. 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.
