Our Heat Pump Repair Process

Our proven process ensures your heat pump repair project is done right the first time.

1

System Evaluation & Mode Testing

Our St. Marys 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.

2

Refrigerant Circuit Diagnosis

KIC Refrigeration performs a complete refrigerant circuit analysis on your St. Marys, OH heat pump. We measure high-side and low-side pressures against the manufacturer target chart for current outdoor ambient temperature, calculate subcooling at the condenser and superheat at the evaporator, and use electronic leak detectors to locate any refrigerant loss.

3

Component Repair or Replacement

We replace the failed component — compressor, reversing valve, defrost board, contactor, capacitor, or metering device — using OEM or equivalent parts rated for your system tonnage and refrigerant type.

4

Performance Verification

Our St. Marys 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.

Heat Pump Repair FAQ — St. Marys, OH

Everything you need to know before scheduling heat pump repair for your property.

How much does heat pump repair cost in St. Marys, OH?

Heat pump repair in St. Marys 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 St. Marys property, so you know exactly what the repair will cost.

Should I repair or replace my heat pump in St. Marys?

The general rule is to repair if the system is under 10 years old and the repair costs less than 50 percent of a replacement. Heat pumps over 12 to 15 years old — especially units still running on R-22 refrigerant — are often better replaced with a new R-410A system that offers higher SEER2 and HSPF2 efficiency ratings and lower operating costs. A new variable-speed heat pump can reduce your St. Marys energy bills by 30 to 40 percent compared to an aging single-stage unit. KIC Refrigeration gives honest repair-versus-replace advice based on your specific equipment age, condition, and repair history rather than pushing unnecessary replacements.

How long does heat pump repair take in St. Marys?

Most heat pump repairs in St. Marys 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 St. Marys home with a fully stocked truck to minimize return trips and keep your downtime as short as possible.

Why does my heat pump ice up in St. Marys?

Heat pump icing is caused by conditions that prevent the defrost cycle from working correctly. The most common culprits are low refrigerant charge from a slow leak, a dirty or blocked outdoor coil that restricts airflow, a failed defrost control board or timer that does not initiate the defrost sequence, a stuck defrost relay, or a malfunctioning outdoor fan motor. In normal operation, the defrost cycle activates every 30 to 90 minutes during cold weather, reversing the system briefly to melt accumulated frost. When any component in this chain fails, ice builds up until the unit shuts down on high-pressure safety. KIC Refrigeration tests the complete defrost circuit and refrigerant charge at your St. Marys, OH home to identify and fix the root cause.
