KIC Refrigeration begins every heat pump repair in Duncan, OK 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 Duncan 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 Duncan, OK 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.
Everything you need to know before scheduling heat pump repair for your property.
Heat pump repair in Duncan 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 Duncan property, so you know exactly what the repair will cost.
Yes. KIC Refrigeration provides 24/7 emergency heat pump repair in Duncan and surrounding Oklahoma 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.

Call our Duncan emergency line any time and we will have a technician on the way to your property as quickly as possible.
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 Duncan property.
KIC Refrigeration provides a comprehensive workmanship warranty on all heat pump repairs performed in Duncan, OK. 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.
