Ten months of work, most of it in tough conditions
Your system runs almost year round in Laurens County, heat from November through March and cooling from May through September. That leaves it little time to rest. Summer afternoons averaging 89°F keep the compressor working hard for five straight months, and winter nights near 34°F put the same steady demand on the heat exchanger and igniter through the other five.
Most homes here heat with electricity, so a heat pump or electric furnace carries that load directly instead of splitting it with gas. Storms add another risk. The county has seen 59 damaging wind events over the past decade, and 45% of South Carolina households lost power for at least a day in 2024. Most systems come back on by themselves once power returns, but the wiring and controls still take the hit when a surge or a hard restart follows.

- Why is my heat not working?
- Start with the thermostat. Make sure it is set to heat, not just on, and that the temperature is set above the room temperature. If that looks right, check the breaker for the furnace or air handler, since a tripped breaker will shut the whole system down with no warning. Most homes here heat with electricity, so a tripped breaker or blown fuse is a common reason heat stops. If power is fine and you still get no heat, a contractor will need to look at the igniter or the heating elements.
- Why is my system running but not cooling the house?
- Check the air filter first. A filter clogged with dust blocks airflow across the coil, and when that happens the coil can freeze up and stop cooling even though the system keeps running. Look at the outdoor unit too. If the coils are covered in leaves, grass clippings or dirt, the system cannot release heat outside and the air coming from your vents will feel warm. If the filter is clean and the outdoor unit is clear, the system likely needs a contractor to check refrigerant levels or the compressor.
- What can I check before calling for HVAC repair?
- Check the thermostat settings, the batteries in it if it has them, and the breaker for the unit. These cause more no-heat and no-cool calls than anything mechanical. Next, look at the air filter. A filter that has not been changed in months restricts airflow enough to make a furnace or air conditioner struggle or shut off. If the outdoor unit is involved, clear away any leaves, mulch or debris piled against it, especially after a storm, since damaging wind is common here and debris against the unit can build up fast. If everything checks out and the problem is still there, a contractor will need to diagnose it further.
