Our proven process ensures your ac repair project is done right the first time.
Our Hillsborough 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.
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.
KIC Refrigeration performs AC repairs in Hillsborough, NH 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.
Our Hillsborough 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.
Everything you need to know before scheduling ac repair for your property.
AC repair in Hillsborough 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 Hillsborough 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 Hillsborough home and measures suction pressure, discharge pressure, superheat, and subcooling to diagnose the exact cause.
Most AC repairs in Hillsborough 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 Hillsborough home with a fully stocked truck to complete most repairs in a single visit.
