Our AC Repair Process

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

1

Symptom Assessment & Safety Check

We assess your air conditioning problem — no cooling, weak airflow, strange noises, ice buildup, or short cycling — and perform a safety check on electrical connections, circuit breaker, disconnect, and thermostat wiring before beginning hands-on diagnostics.

2

Electrical & Refrigerant Diagnostics

At your Antioch property, our technician tests the run and start capacitors with a capacitance meter, checks the contactor for pitting and voltage drop, measures compressor amperage against rated load amps, and reads suction and discharge pressures to calculate superheat and subcooling against the manufacturer charge chart for current conditions.

3

Targeted Repair

KIC Refrigeration performs AC repairs in Antioch, CA by the book. For electrical failures, we match the replacement part to factory specifications. For sealed-system repairs, we follow EPA Section 608 recovery procedures, braze with nitrogen purge, pressure test to 300 PSI, evacuate to 500 microns, and charge by weight — never by guessing or topping off.

4

Performance Verification

We run the system for a minimum of 15 minutes, measure the temperature split across the evaporator coil (target: 16 to 22 degrees), verify suction and discharge pressures, check condenser fan and blower motor amperage, and confirm the thermostat cycles the system off at setpoint.

AC Repair FAQ — Antioch, CA

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

How much does AC repair cost in Antioch, CA?

AC repair in Antioch 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 Antioch property so there are no surprises on the invoice.

Why is my AC running but not cooling in Antioch?

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 Antioch home and measures suction pressure, discharge pressure, superheat, and subcooling to diagnose the exact cause.

Why does my AC keep tripping the breaker in Antioch?

An AC that repeatedly trips the circuit breaker is a safety issue that should not be ignored or reset repeatedly. The most common causes are a shorted compressor winding drawing excessive amperage, a failing run capacitor that cannot provide the boost needed for compressor startup, a locked rotor condition from a mechanically seized compressor, a ground fault from damaged wiring or a grounded compressor motor, or an undersized breaker that cannot handle the inrush current. Each reset on a breaker weakens it over time. KIC Refrigeration performs thorough electrical diagnostics at your Antioch property — including megohm resistance testing on compressor windings and amperage measurements — to identify the root cause and repair it safely.

Can KIC Refrigeration repair all AC brands in Antioch?

KIC Refrigeration repairs every major air conditioning brand installed in Antioch homes and commercial properties — Carrier, Trane, Lennox, Rheem, Goodman, Daikin, York, Bryant, Amana, Ruud, Heil, and all other manufacturers. Our technicians hold EPA Section 608 Universal certification for refrigerant handling and are trained to work with R-410A, R-22, R-32, R-454B, and all other regulated refrigerants found in residential and light commercial systems. Whether your AC is a 2-ton window package unit or a 5-ton split system, a 20-year-old R-22 unit or a brand-new inverter model, KIC Refrigeration has the diagnostic capability and parts access to repair it correctly at your Antioch property.
