Charleston Housing Stock
The median Charleston home dates to 1956, according to the Census ACS. That makes the typical house about 70 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. Owners live in 62.8% of occupied homes, roughly 13,000 households. The median home value is $187,300, and median household income is $64,512. We use both figures to adjust labor and pricing for this page.
Kanawha County had 10 hail days and 52 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 1.75 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. In Charleston, 20.8% of residents are 65 or older. For older adults, a house with no heat in January or no AC during a heat wave is a medical risk.
