From initial contact to final verification — here is how we handle ac repair.
KIC Refrigeration begins every AC repair in Costa Mesa, CA with a systematic assessment. We verify 24-volt control voltage at the thermostat, check high and low voltage wiring for damage, inspect the disconnect for burned contacts, confirm the breaker is properly sized, and visually inspect both indoor and outdoor units before powering up the system for testing.
We test capacitors, contactors, relays, and the compressor windings with a multimeter. We connect manifold gauges to measure suction and discharge pressures, calculate superheat and subcooling, and compare all readings to the manufacturer specification for your unit.
Our Costa Mesa technician replaces the failed part with the correct replacement for your unit make, model, and tonnage. If the failure involves the sealed refrigerant system, we recover the charge, make the repair, pressure test with nitrogen, evacuate to below 500 microns, and weigh in the correct charge of R-410A or the specified refrigerant.
KIC Refrigeration verifies every AC repair in Costa Mesa, CA with a comprehensive performance test. We confirm temperature split, superheat, subcooling, compressor amperage, condenser fan amperage, blower CFM, and thermostat operation. We document all readings and explain the results before we consider the job complete.

AC repair in Costa Mesa typically costs $150 to $500 for common component failures including run capacitors ($150 to $250), contactors ($150 to $350), condenser fan motors ($250 to $500), and blower motors ($300 to $600). Compressor replacement is the most expensive repair at $1,500 to $3,500 depending on unit tonnage and whether the system uses R-410A or older R-22 refrigerant. Evaporator coil replacement runs $800 to $2,500 including the refrigerant recovery and recharge. KIC Refrigeration provides a detailed written estimate with itemized parts and labor costs before beginning any AC repair at your Costa Mesa property so there are no surprises on the invoice.
Most AC repairs in Costa Mesa are completed in 1 to 2 hours during a single service visit. Capacitor and contactor replacements are quick fixes that take 15 to 30 minutes of hands-on time. Fan motor and blower motor replacements take 1 to 2 hours including wiring and testing. Compressor replacement is the most time-intensive repair at 3 to 6 hours because it requires refrigerant recovery with an EPA-certified machine, compressor removal, new compressor installation, nitrogen-purged brazing, pressure testing at 300 PSI, evacuation to below 500 microns, and recharging by weight. KIC Refrigeration arrives at your Costa Mesa home with a fully stocked truck to complete most repairs in a single visit.
An AC that runs but produces little or no cooling is most commonly caused by low refrigerant charge from a leak, which reduces the suction pressure and causes the evaporator coil temperature to drop below 32 degrees, forming ice that blocks airflow completely. Other causes include a dirty condenser coil that cannot reject heat, a failed compressor that runs but does not pump refrigerant, a stuck or failed metering device — either a TXV or fixed orifice — that restricts refrigerant flow, or a blower motor running at reduced speed due to a failing capacitor. KIC Refrigeration connects manifold gauges at your Costa Mesa home and measures suction pressure, discharge pressure, superheat, and subcooling to diagnose the exact cause.
The industry guideline is to repair if the unit is under 10 years old and the repair costs less than 50 percent of a new system. AC units over 15 years old — especially those running R-22 refrigerant — are almost always better replaced. R-22 has been phased out of production and the remaining supply costs $80 to $150 per pound, making even minor refrigerant leaks prohibitively expensive to fix. A new 16 SEER2 system uses approximately 38 percent less energy than a 10 SEER unit, and many qualify for the federal energy tax credit. KIC Refrigeration helps Costa Mesa homeowners evaluate repair versus replacement based on equipment age, repair history, refrigerant type, and projected energy savings.

"Replaced our entire HVAC system and the crew was phenomenal. Finished ahead of schedule and left the house cleaner than they found it."
"Mini split repair was done right the first time. The outdoor unit had a refrigerant leak and they found it, fixed it, and recharged the system same day."
"KIC Refrigeration installed our new heat pump system and the difference is incredible. Our energy bills dropped noticeably the very first month."
