Charleston Weather and HVAC Load
In a normal year, Charleston racks up 4,353 heating and 1,162 cooling degree days (NOAA 1991-2020 normals). Heating is the bigger job here. The AC still runs every summer, but it works far fewer hours than the furnace does. On average, Charleston gets 94 freezing nights and 24 days above 90°F per year. Snowfall averages about 32 inches. On the cooling side, a 2,000 sq ft house here usually needs around 3 tons. A tight, well-insulated house may get by with half a ton less.

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. Mention it when you call, since many companies put those calls first.

- Refrigerant type and how many pounds it takes
- Whether the equipment sits in a tight attic or on a roof
- Nights, weekends and holidays

West Virginia Licensing and Efficiency Rules
West Virginia falls in the DOE's North region. New split central air conditioners must meet at least 13.4 SEER2, and heat pumps sold anywhere in the U.S. need 14.3 SEER2 and 7.5 HSPF2. Most repairs don't need a permit. Anyone who opens the refrigerant circuit does need EPA Section 608 certification, and in West Virginia the company should carry a state license or registration. Ask for both.
Before You Hire
- If the compressor is gone on an older unit, get a replacement quote before you pay for the repair.
- Ask for the per-pound refrigerant price before any work starts.
- Swap the air filter and check the breaker before you call anyone.
