Heat Pump Repair in Columbia, SC
Heat pumps do most of the heating and cooling work in the Midlands, so a fault takes out both seasons at once. Describe the symptom and we will connect you with a licensed Columbia-area contractor who works on them.
Common symptoms and what they usually mean
Blowing cool air in heating mode
Heat pumps deliver air cooler than a gas furnace does by design, so this is not always a fault. It becomes one when the house will not reach setpoint, or when the system has dropped to auxiliary strip heat and stayed there - which shows up as a sharply higher power bill.
Outdoor unit iced over in winter
A heat pump ices up in cold, damp weather and should clear itself on a defrost cycle. If it stays encased in ice, the defrost control, reversing valve, or sensor has likely failed. Do not chip the ice off - it damages the coil.
Stuck in one mode
A heat pump that will heat but not cool, or cool but not heat, usually points at the reversing valve or its solenoid. Note which mode fails, because that distinction narrows the diagnosis considerably.
Auxiliary heat running constantly
Emergency or auxiliary strip heat is expensive to run. If it is engaging on mild days, the heat pump is not carrying the load - a refrigerant, airflow or control problem worth catching early.
Questions people ask
Why are heat pumps so common in Columbia?
Columbia's mild winters and long cooling season suit them. A single system covers both, and the winter is rarely cold enough for long enough to make a heat pump inefficient the way it would be further north.
Can the same contractor service a heat pump and a straight AC system?
Generally yes - licensed HVAC contractors in South Carolina work on both. Mention the system type when you call so the right parts are on the truck.
