South Burlington Housing Stock
Census figures put the median build year in South Burlington at 1988, so a typical house here has about 38 years on it. Plenty of houses from this period still run original 1990s or early-2000s equipment, which is past its expected service life. Owners live in 60.1% of occupied homes, roughly 5,600 households. With a median household income of $97,229 and a median home value of $399,600, local labor rates come out above the national middle in our model.
Between 2020 and 2025, NOAA's Storm Events Database logged 4 hail days and 21 days with damaging thunderstorm winds in Chittenden County. The largest hail reported was 1.75 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.
