From initial contact to final verification — here is how we handle ac repair.
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 Southborough, 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 Southborough 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 Southborough 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 Southborough property so there are no surprises on the invoice.
Yes. KIC Refrigeration offers same-day AC repair in Southborough 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 Southborough 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 Southborough AC repair call.
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 Southborough property — including megohm resistance testing on compressor windings and amperage measurements — to identify the root cause and repair it safely.
AC refrigerant recharge in Southborough 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.
Our reputation is built on certified technicians, honest pricing, and results that last.
