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 Cottage Grove 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 Cottage Grove, WI 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 Cottage Grove 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 Cottage Grove 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 Cottage Grove 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 Cottage Grove property — including megohm resistance testing on compressor windings and amperage measurements — to identify the root cause and repair it safely.
Most AC repairs in Cottage Grove 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 Cottage Grove home with a fully stocked truck to complete most repairs in a single visit.
