Our AC Repair Process

How our NATE-certified technicians deliver quality ac repair results from start to finish.

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 Fullerton 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 Fullerton, 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 — Fullerton, CA

Get answers to the ac repair questions our customers ask most often.

How much does AC repair cost in Fullerton, CA?

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

Should I repair or replace my AC unit in Fullerton?

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 Fullerton homeowners evaluate repair versus replacement based on equipment age, repair history, refrigerant type, and projected energy savings.

Why does my AC keep tripping the breaker in Fullerton?

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 Fullerton property — including megohm resistance testing on compressor windings and amperage measurements — to identify the root cause and repair it safely.

Does KIC Refrigeration offer same-day AC repair in Fullerton?

Yes. KIC Refrigeration offers same-day AC repair in Fullerton for the majority of service calls received before early afternoon. Our service vehicles carry over 200 common AC parts including capacitors in multiple ratings, contactors, condenser fan motors, blower motors, hard-start kits, control boards, and R-410A refrigerant — enabling us to complete most repairs during the initial visit without waiting on parts orders. We understand that losing air conditioning in Fullerton during summer heat is more than a comfort issue, particularly for elderly residents, young children, and people with respiratory conditions. KIC Refrigeration prioritizes fast response and first-visit resolution for every Fullerton AC repair call.
