South Bend Housing Stock
Half the homes in South Bend were built before 1955 (Census ACS median), so the typical house is about 71 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 24,000 households here own their home, 58.8% of the occupied total. Homes here have a median value of $124,500 and households a median income of $52,512. Those two numbers drive the labor adjustment in our estimate.
St. Joseph County had 5 hail days and 31 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 2.5 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. St. Joseph County also had 4 tornado days in that period.
