Our AC Repair Process

A clear, step-by-step approach to every ac repair project we take on.

1

Symptom Assessment & Safety Check

KIC Refrigeration begins every AC repair in San Marcos, TX 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.

2

Electrical & Refrigerant Diagnostics

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.

3

Targeted Repair

Our San Marcos 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.

4

Performance Verification

KIC Refrigeration verifies every AC repair in San Marcos, TX 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 FAQ — San Marcos, TX

Common questions about ac repair costs, timelines, and what to expect.

How much does AC repair cost in San Marcos, TX?

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

What does AC refrigerant recharge cost in San Marcos?

AC refrigerant recharge in San Marcos costs $200 to $500 for R-410A systems at roughly $50 to $80 per pound, and $400 to $1,200 for older R-22 systems at $80 to $150 per pound due to the phaseout-driven supply shortage. However, simply adding refrigerant without finding the leak is a temporary and wasteful fix — the charge will leak out again in weeks or months and you will be back in the same situation. KIC Refrigeration always locates the leak first using electronic leak detectors and UV dye, repairs the leaking component, evacuates the system to remove moisture and air, and recharges by weight to the manufacturer specification. This approach fixes the problem permanently.

How long does AC repair take in San Marcos?

Most AC repairs in San Marcos 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 San Marcos home with a fully stocked truck to complete most repairs in a single visit.

Does KIC Refrigeration offer same-day AC repair in San Marcos?

Yes. KIC Refrigeration offers same-day AC repair in San Marcos 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 San Marcos 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 San Marcos AC repair call.
