How our NATE-certified technicians deliver quality heat pump repair results from start to finish.
KIC Refrigeration begins every heat pump repair in Vernon Hills, IL with a dual-mode performance test. We measure supply air temperatures in heat and cool, verify the reversing valve energizes and de-energizes properly, and test the defrost control board to confirm it initiates defrost cycles at the correct intervals.
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.
Our Vernon Hills technician installs the replacement part with proper brazing techniques for sealed-system components, recovers refrigerant before opening the circuit, pulls a 500-micron vacuum on reassembly, and recharges to the manufacturer-specified weight.
KIC Refrigeration does not consider your Vernon Hills, IL heat pump repair complete until every performance metric checks out. We verify pressures, temperatures, amperage draws, defrost timing, reversing valve switching, and thermostat communication before signing off on the work.

Heat pump repair in Vernon Hills 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 Vernon Hills property, so you know exactly what the repair will cost.
KIC Refrigeration provides a comprehensive workmanship warranty on all heat pump repairs performed in Vernon Hills, IL. Replacement parts carry manufacturer warranties that range from 1 to 10 years depending on the component — compressors typically carry 5 to 10 year manufacturer warranties, while electrical components like capacitors and contactors carry 1 to 2 year warranties. If a part we install fails within the warranty period, we replace it at no charge for the part and provide the labor to install it. KIC Refrigeration handles all warranty documentation and claims on your behalf so you never have to chase paperwork. Ask your technician about specific warranty terms during your service appointment.
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 Vernon Hills, IL home to identify and fix the root cause.
