Ten months of work a year on your heat pump
Your heat pump runs from November through March to keep the house warm, then switches over and runs May through September to keep it cool. That's ten months a year with almost no rest in between. Winter nights averaging 34°F keep it cycling through most of the dark hours. Summer afternoons near 89°F push it hard the other direction. The compressor and the reversing valve carry that load both ways, and a weak one tends to fail right around the switch from heating to cooling or back.
Storms add their own strain here. This area has logged 59 damaging wind events over the past ten years, and 45% of South Carolina households lost power for a full day or more in 2024. A heat pump that loses power mid-cycle and comes back on wrong often shows it as short cycling, or as a system that runs but never quite gets the house to temperature.

- Why is my heat pump blowing cold air?
- In winter, your heat pump puts out air that feels cool compared to your skin even when it is working right, since it is well below body temperature but still warmer than the room. If the air feels truly cold with no warmth at all, check that the thermostat is set to heat and not fan only. If it is set right and still blowing cold, the reversing valve may be stuck in cooling mode, or the unit could be low on refrigerant. Either one needs a contractor to look at it.
- Why is there ice on my heat pump?
- Some frost on the outdoor unit in winter is normal, and your heat pump defrosts itself on a regular cycle to clear it. If you are seeing thick ice that does not go away, or ice building up on the coil even in mild weather, something is keeping the defrost cycle from working, like a bad sensor, a stuck reversing valve, or a fan that has stopped turning. Ice that is not clearing on its own is worth having checked before it blocks airflow across the coil entirely.
- Why is my heat pump running but not cooling?
- If the unit is running but the air coming out is not cold, start with the filter. A clogged filter starves the coil of airflow and the whole system stops cooling the house even though it is on. If the filter is clean, check the outdoor unit for leaves, grass clippings, or anything blocking the coil, since a blocked outdoor coil struggles to move heat outside on a hot afternoon. If both of those look fine and it still is not cooling, the refrigerant charge or the compressor itself likely needs a contractor's attention.
