Professional ac repair services for homes and businesses in Sonoma and surrounding California communities.
When your air conditioner in Sonoma, California blows warm air, short cycles, or fails to start, KIC Refrigeration technicians identify the exact cause through systematic testing of the refrigerant circuit, compressor windings, capacitors, and control board. We restore reliable cooling performance with precision repairs that address the root problem, not just the symptoms.
Properties throughout Sonoma (pop. 10,546) face unique demands when it comes to ac repair. California heating loads, cooling calculations, and the insulation levels and duct configurations found in Sonoma homes all influence the approach we take. KIC Refrigeration tailors every ac repair project to the conditions your property actually faces — no generic solutions.
Choosing the right contractor for ac repair in Sonoma, CA makes all the difference between efficient comfort and a system that short-cycles. KIC Refrigeration uses Manual J load calculations, installs to manufacturer specifications, and backs every project with a warranty. Call (866) 858-2961 to schedule your free assessment.
How our NATE-certified technicians deliver quality ac repair results from start to finish.
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.
KIC Refrigeration diagnoses AC failures in Sonoma, CA with precision electrical and refrigerant testing. We check capacitors within 6 percent of rated microfarads, measure contactor coil resistance, verify compressor winding resistance for shorts and opens, and test the refrigerant circuit — comparing suction pressure, discharge pressure, subcooling, and superheat to the manufacturer target values for the current outdoor ambient temperature.
Our Sonoma 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.
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.
Transparent answers about ac repair from our certified technicians.
AC repair in Sonoma 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 Sonoma property so there are no surprises on the invoice.
KIC Refrigeration repairs every major air conditioning brand installed in Sonoma 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 Sonoma property.
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 Sonoma property — including megohm resistance testing on compressor windings and amperage measurements — to identify the root cause and repair it safely.
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 Sonoma home and measures suction pressure, discharge pressure, superheat, and subcooling to diagnose the exact cause.
Our reputation is built on certified technicians, honest pricing, and results that last.
"Emergency repair on a Sunday night and they still showed up within the hour. Furnace was back up and running before bedtime. Lifesavers."
"Heat pump was not heating properly. They found a bad reversing valve and had it swapped out the next day. House is warm again and the system runs great."
"Mini split installation went smoothly. Clean work, no mess left behind. Would have liked a bit more explanation on the maintenance schedule but overall very happy."
