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, and furnaces and heat pumps in Charleston put in far more hours than the air conditioner. On average, Charleston gets 94 freezing nights and 24 days above 90°F per year. Snowfall averages about 32 inches. For a 2,000 sq ft house, this climate points to a heating load somewhere near 55,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.

Charleston Housing Stock
The median Charleston home dates to 1956, according to the Census ACS. That makes the typical house about 70 years old. Many houses that age were built with hot-water or steam heat, and plenty still run cast-iron boilers and radiators. 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.

West Virginia Permits, Efficiency Rules and Rebates
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. Expect the contractor to pull a mechanical permit for a replacement job in Charleston. If a bidder suggests skipping it, move on. Also ask for a West Virginia license or registration number and proof of insurance. The federal 25C tax credit ended for equipment installed after December 31, 2025, so incentives now come mostly from utilities and state programs. Check your electric and gas utility's rebate page before you pick equipment.
Before You Hire
- For a steam system, hire a contractor who works on steam regularly.
- Ask your gas or oil company about rebates on condensing boilers.
- Ask for a heat-loss calculation. A lot of old boilers are much bigger than the house needs.
