Ten months of work, with storms that cut the power
Your system runs almost year round in Greenwood County. Heat from November through March, cooling from May through September, only two months off. Winter nights average 35°F, so the heat runs steady but not brutal. Summer afternoons average 90°F, and that is where the strain shows, the compressor cycling on all afternoon to keep up.
Most homes here heat with electricity, which means a power outage takes the heat down with it. Storms are not rare in this county. Over the last ten years it has seen 53 damaging wind events and 2 winter storms, and statewide, close to half of households lost power for a full day or more in 2024. When the power drops and comes back, most systems restart on their own. If yours does not, that is worth a call before you assume the worst.

- Why is my heat not working?
- Start with the thermostat. Make sure it is set to heat and the temperature is set above the room reading, since a setting bumped a degree or two can look like a dead system. Check the breaker next, since a tripped one will shut the furnace down with no other sign. If the furnace runs but never lights, or lights and then shuts off, that points to the igniter or flame sensor, and a contractor will need to look at it. With 67.7% of homes here heating with electricity, a tripped breaker or a heat pump stuck in defrost is worth ruling out before anything else.
- Why is my system running but not cooling the house?
- Check the air filter first. A filter clogged with dust blocks airflow across the indoor coil, and that coil can ice over, which stops it from cooling the air at all even though the blower keeps running. Check that the outdoor unit is not buried in leaves or blocked by anything on top of it, since it needs open airflow to release the heat it is pulling from inside. If the filter is clean and the outdoor unit is clear and the house still is not cooling, especially with afternoons near 90°F, the system likely needs refrigerant checked or a part looked at, and that is a job for a contractor.
- What can I check before calling for HVAC repair?
- Check the thermostat settings, the breaker for the system, and the air filter. Those checks cause a real share of no heat and no cooling calls and take a minute each to rule out. If the outdoor unit is involved, look for anything blocking it, leaves, a cover, plant growth. Damaging wind comes through here often enough that it is worth checking the outdoor unit and the breaker after any bad weather before assuming the system itself has failed. If everything checks out and the problem is still there, a contractor will need to diagnose it further.
