Our AC Repair Process

Our proven process ensures your ac repair project is done right the first time.

1

Symptom Assessment & Safety Check

Our Knoxville technician listens to your description of the problem, inspects the thermostat settings and wiring, checks the electrical disconnect and breaker, and performs a visual inspection of the outdoor condenser and indoor air handler for obvious issues like a frozen coil, tripped safety switch, or burned wiring.

2

Electrical & Refrigerant Diagnostics

KIC Refrigeration diagnoses AC failures in Knoxville, TN 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.

3

Targeted Repair

We replace the failed component — capacitor, contactor, fan motor, compressor, or metering device — using parts rated for your system. For refrigerant leaks, we locate the leak, repair or replace the leaking component, evacuate, and recharge the system by weight.

4

Performance Verification

Our Knoxville technician verifies the repair by running the AC through a full cooling cycle. We measure supply and return air temperatures at the air handler to confirm a 16 to 22 degree split, check that suction pressure produces 35 to 45 degree evaporator saturation temperature, and verify the system cycles cleanly on and off.

AC Repair FAQ — Knoxville, TN

Everything you need to know before scheduling ac repair for your property.

How much does AC repair cost in Knoxville, TN?

AC repair in Knoxville 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 Knoxville property so there are no surprises on the invoice.

How long does AC repair take in Knoxville?

Most AC repairs in Knoxville 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 Knoxville home with a fully stocked truck to complete most repairs in a single visit.

Why is my AC running but not cooling in Knoxville?

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 Knoxville home and measures suction pressure, discharge pressure, superheat, and subcooling to diagnose the exact cause.

Does KIC Refrigeration offer same-day AC repair in Knoxville?

Yes. KIC Refrigeration offers same-day AC repair in Knoxville 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 Knoxville 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 Knoxville AC repair call.
