Columbia Weather and HVAC Load
Columbia logs 2,572 heating degree days and 2,075 cooling degree days in a normal year, based on the closest NOAA weather station. Neither season dominates in Columbia. That balance is a big reason heat pumps and dual-fuel systems sell well in South Carolina. A normal year brings 47 nights at or below freezing and 73 days over 90°F. For a 2,000 sq ft house, this climate points to a heating load somewhere near 40,000 BTU/h. Treat that as a starting number. A Manual J calculation will move it up or down based on insulation and windows.

Richland County had 12 hail days and 64 days with damaging thunderstorm winds from 2020 through 2025, according to NOAA storm records. The largest hail reported was 1 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. Richland County also had 4 tornado days in that period.
Symptoms Worth a Service Call

- Which part failed: a flame sensor costs far less than a control board or blower motor
- Whether the part is still under the manufacturer warranty
- The diagnostic or service call fee
- The furnace's age and brand, which affect parts availability
- Night, weekend or holiday rates

South Carolina Licensing and Efficiency Rules
South Carolina is in the DOE's Southeast region, where new split central air conditioners need at least 14.3 SEER2 (13.8 SEER2 for systems of 45,000 BTU/h and up). Most repairs don't need a permit. Anyone who opens the refrigerant circuit does need EPA Section 608 certification, and in South Carolina the company should carry a state license or registration. Ask for both.
Before You Hire
- Ask whether the diagnostic fee comes off the repair bill.
- Check the filter, the thermostat batteries and the breaker first. Those three cause a surprising number of no-heat calls.
- Have the model and serial number from the furnace label handy. Parts get ordered faster.
