Greensboro Housing Stock
Half the homes in Greensboro were built before 1983 (Census ACS median), so the typical house is about 43 years old. A lot of these homes are on their second or third system by now. The ductwork is usually original, and leaky joints are common. About 61,000 households here own their home, 50.3% of the occupied total. With a median household income of $58,884 and a median home value of $221,300, local labor rates come out below the national middle in our model.
Between 2020 and 2025, NOAA's Storm Events Database logged 10 hail days and 48 days with damaging thunderstorm winds in Guilford County. The largest hail reported was 2 inches across. Hail flattens the thin aluminum fins on condenser coils and cuts airflow. After a big storm, take a look at the outdoor unit; homeowners insurance often covers the damage.
