Your satisfaction is guaranteed.
From initial contact to final verification — here is how we handle heat pump repair.
Our Ontario 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.
KIC Refrigeration performs a complete refrigerant circuit analysis on your Ontario, CA 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.
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.
Our Ontario 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 in Ontario 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 Ontario property, so you know exactly what the repair will cost.
Yes. KIC Refrigeration provides 24/7 emergency heat pump repair in Ontario and surrounding California communities every day of the year including holidays. A failed heat pump in freezing weather is a genuine emergency — indoor temperatures can drop below 40 degrees within hours, putting water pipes at risk of freezing and bursting. Our emergency technicians are dispatched with fully stocked vehicles carrying capacitors, contactors, defrost boards, fan motors, and refrigerant so the most common failures can be repaired on the first visit. Call our Ontario emergency line any time and we will have a technician on the way to your property as quickly as possible.
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 Ontario, CA home to identify and fix the root cause.
KIC Refrigeration repairs every major heat pump brand installed in Ontario homes and businesses — Carrier, Trane, Lennox, Rheem, Goodman, Daikin, York, Bryant, Amana, Mitsubishi, Fujitsu, and LG. Our NATE-certified technicians are trained on both conventional ducted split systems and ductless mini-split heat pumps across all tonnage ratings from 1.5 to 5 tons. We work with every common refrigerant including R-410A, R-22, R-32, and R-454B. Whether your system is a 30-year-old R-22 unit or a brand-new variable-speed inverter model, KIC Refrigeration has the diagnostic tools, replacement parts access, and technical knowledge to repair it correctly at your Ontario property.
