Thomasville runs its system almost year round
Heat from October through April, then cooling from May through September. That is close to twelve months of work for one system, with only a short break between seasons to recover.
Winter nights here average 31°F, cold enough that the system cycles on and off for hours through the night. Most homes here heat with electricity, so a heat pump or electric furnace is doing that work, and the parts that start it up take the wear. Summer afternoons average 87°F, and the air conditioner runs long stretches to keep up, which pushes hard on the compressor and the capacitor that gets it going. The area has seen its share of winter storms and damaging wind over the past ten years, and in 2024 a quarter of North Carolina households lost power for a day or more. A system that loses power mid-cycle and comes back on to a house that has drifted far from its set temperature is starting under load, not idling.

North Carolina requires HVAC contractors to hold a state license.
That license comes from the State Board of Examiners of Plumbing, Heating and Fire Sprinkler Contractors, and it means the contractor was tested before the state put their name on file. The license belongs to the contractor, not to the job, so the same license that let them take on this repair covers whatever other work they do.
For a repair on your heating and cooling system, that license is what stands behind the person doing the work. It tells you the state has a record of them and that they were tested on the trade before they were allowed to take jobs like this one.

- Why is my heat not working?
- Start with the thermostat. Check the batteries, make sure it is set to heat, and confirm the temperature is set above the room temperature. If that all looks right, check the breaker for the furnace and, if you have gas heat, make sure the gas valve is open. Furnaces with a standing pilot can have the pilot light go out, and electric ignition models can fail to light if the igniter or flame sensor has worn out. If nothing brings it back on, a contractor can find out which part failed.
- Why is my system running but not cooling the house?
- The most common cause is a dirty air filter blocking airflow, so check that first and replace it if it looks gray or clogged. If the filter is clean, check the outdoor unit for anything blocking it, like leaves or grass clippings, since it needs open airflow to release heat. A refrigerant leak or a failing compressor will also leave a system running without cooling, and those need a contractor to diagnose. Given how hot afternoons get here, it is worth checking these things quickly rather than waiting.
- What can I check before calling for HVAC repair?
- Check the thermostat first, including the batteries and the mode setting. Check the breaker panel to make sure nothing has tripped. Check the air filter and replace it if it is dirty, since a clogged filter can cause heating or cooling problems that look like something worse. If the outdoor unit is involved, make sure nothing is blocking it. If the system still is not working after that, a contractor can diagnose what is actually wrong.
