Your heat pump works ten months a year here
In Aiken County the heat pump runs from November through March, then switches over and runs May through September. Ten months of the year it is either the only thing keeping the house warm or the only thing keeping it cool. That is more run time than most homes ask of one system, and it means less downtime for parts to rest.
Winter nights averaging 36°F push the system into defrost cycles more often, and the reversing valve that switches it between heating and cooling takes the wear from every one of those switches. Summer afternoons near 91°F keep the compressor working hard for months straight. With 185 damaging wind events recorded here over the past ten years and 45% of South Carolina households losing power for at least a day in 2024, the electrical components and the outdoor unit itself take hits that a system in a calmer climate would not. You may notice the heat pump running longer than it used to, blowing air that is not quite warm enough on a cold night, or not starting back up after the power comes on.

- Why is my heat pump blowing cold air?
- In heating mode, a heat pump puts out air that feels cool next to your skin even when it's working right, usually around body temperature, because it moves heat rather than burning fuel to make it. If the air feels truly cold, not just mild, check that the outdoor unit isn't caked in ice and that your air filter isn't clogged. If the system is also short on refrigerant or the reversing valve has failed, it will run without heating at all, and that needs a contractor to check.
- Why is there ice on my heat pump?
- Some frost on the outdoor unit during a cold snap is normal, and the system defrosts itself on a timer, melting it off every so often. On winter nights here dropping to 36°F, you'll see this more often. If the coil is fully covered in thick ice that doesn't clear after a few hours, or ice is building up even when it's not that cold out, the defrost control or a fan motor may have failed, and that's worth having a contractor look at.
- Why is my heat pump running but not cooling?
- If the outdoor unit and indoor fan are both running but the air coming out isn't cool, start with the filter. A clogged filter restricts airflow across the indoor coil, and a dirty outdoor coil does the same thing on the other end. With summer afternoons here reaching 91°F, a heat pump fighting a clogged filter or blocked outdoor coil will run constantly without keeping up. If both are clean and it's still not cooling, the refrigerant charge or the compressor itself may be the problem, and that calls for a contractor with gauges to check it.
