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.
At your McHenry 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.
KIC Refrigeration performs AC repairs in McHenry, IL 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.
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 in McHenry 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 McHenry property so there are no surprises on the invoice.
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 McHenry homeowners evaluate repair versus replacement based on equipment age, repair history, refrigerant type, and projected energy savings.
Most AC repairs in McHenry 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 McHenry home with a fully stocked truck to complete most repairs in a single visit.
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 McHenry property — including megohm resistance testing on compressor windings and amperage measurements — to identify the root cause and repair it safely.
Our reputation is built on certified technicians, honest pricing, and results that last.
