A clear, step-by-step approach to every heat pump repair project we take on.
Our Rock Hill technician evaluates your heat pump by running it through a complete heating cycle and cooling cycle. We verify reversing valve solenoid operation, check defrost board timing, and measure output temperatures to determine if the system is switching modes correctly.
We connect manifold gauges to check suction and discharge pressures, calculate superheat and subcooling, and compare readings to the manufacturer charge chart. Incorrect pressures reveal leaks, restrictions, or compressor issues.
KIC Refrigeration repairs your Rock Hill, SC heat pump with precision. For sealed-system work, we recover refrigerant with a certified recovery machine, braze with nitrogen flowing to prevent scale, pressure test with dry nitrogen to 300 PSI, evacuate to below 500 microns, and weigh in the exact factory charge.
Our Rock Hill crew verifies the repair by running the system in both modes. We confirm superheat and subcooling are within 2 degrees of target, the defrost cycle initiates and terminates properly, and the temperature split across the air handler is 15 to 20 degrees in cooling and 20 to 30 degrees in heating.
Common questions about heat pump repair costs, timelines, and what to expect.
Heat pump repair in Rock Hill typically ranges from $150 to $600 for common component failures like run capacitors, contactors, defrost timers, and condenser fan motors. Reversing valve replacement is a more involved job that runs $800 to $2,000 including refrigerant recovery and recharge. Compressor replacement costs $1,500 to $3,000 depending on the unit tonnage, refrigerant type — whether R-410A or older R-22 — and whether a hard-start kit is needed. KIC Refrigeration provides a detailed written estimate with parts and labor itemized before any work begins at your Rock Hill property, so you know exactly what the repair will cost.
A heat pump blowing cold air in heating mode is most commonly caused by a failed reversing valve solenoid, which gets stuck and prevents the system from switching from cooling to heating. Other causes include low refrigerant charge that reduces the heat output at the condenser coil, a stuck or failed defrost control board that keeps the outdoor unit in defrost mode too long, or a thermostat that has lost communication with the control board. KIC Refrigeration tests the reversing valve by measuring the temperature difference across it, checks refrigerant pressures with manifold gauges, and verifies the defrost sequence to isolate the exact cause at your Rock Hill property.
Most heat pump repairs in Rock Hill are completed in 1 to 3 hours during a single service visit. Common electrical component failures — capacitors, contactors, defrost relays, and flame sensors — typically take 30 to 60 minutes. Fan motor replacements take 1 to 2 hours. Reversing valve and compressor replacements are the most time-intensive repairs at 4 to 6 hours because they require refrigerant recovery with a certified machine, component removal, brazing with nitrogen purge, leak testing, evacuation to below 500 microns, and recharging by weight. KIC Refrigeration arrives at your Rock Hill home with a fully stocked truck to minimize return trips and keep your downtime as short as possible.
