Your satisfaction is guaranteed.
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 Mendon, MA 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 Mendon 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.

AC repair in Mendon 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 Mendon property so there are no surprises on the invoice.
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 Mendon home and measures suction pressure, discharge pressure, superheat, and subcooling to diagnose the exact cause.
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 Mendon property — including megohm resistance testing on compressor windings and amperage measurements — to identify the root cause and repair it safely.
Yes. KIC Refrigeration offers same-day AC repair in Mendon 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 Mendon 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 Mendon AC repair call.
Hear from property owners who chose us for their heating and cooling needs.
"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 repair was done right the first time. The outdoor unit had a refrigerant leak and they found it, fixed it, and recharged the system same day."
"KIC Refrigeration installed our whole-home HVAC system during the renovation. They coordinated perfectly with our contractor and stayed on schedule."
