Cambridge Housing Stock
The median Cambridge home dates to 1948, according to the Census ACS. That makes the typical house about 78 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 17,000 households here own their home, 33.7% of the occupied total. With a median household income of $126,469 and a median home value of $1,040,500, local labor rates come out above the national middle in our model.
Between 2020 and 2025, NOAA's Storm Events Database logged 6 hail days and 42 days with damaging thunderstorm winds in Middlesex County. The largest hail reported was 1 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. Middlesex County also had 2 tornado days in that period.
