A clear, step-by-step approach to every ac repair project we take on.
KIC Refrigeration begins every AC repair in Peterborough, NH 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.
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.
Our Peterborough 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.
KIC Refrigeration verifies every AC repair in Peterborough, NH 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.
Common questions about ac repair costs, timelines, and what to expect.
AC repair in Peterborough 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 Peterborough 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 Peterborough 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 Peterborough property — including megohm resistance testing on compressor windings and amperage measurements — to identify the root cause and repair it safely.
