Our AC Repair Process

A clear, step-by-step approach to every ac repair project we take on.

1

Symptom Assessment & Safety Check

KIC Refrigeration begins every AC repair in Hopkinton, 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.

2

Electrical & Refrigerant Diagnostics

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.

3

Targeted Repair

Our Hopkinton 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.

4

Performance Verification

KIC Refrigeration verifies every AC repair in Hopkinton, 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.

AC Repair FAQ — Hopkinton, NH

Common questions about ac repair costs, timelines, and what to expect.

How much does AC repair cost in Hopkinton, NH?

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

Can KIC Refrigeration repair all AC brands in Hopkinton?

KIC Refrigeration repairs every major air conditioning brand installed in Hopkinton homes and commercial properties — Carrier, Trane, Lennox, Rheem, Goodman, Daikin, York, Bryant, Amana, Ruud, Heil, and all other manufacturers. Our technicians hold EPA Section 608 Universal certification for refrigerant handling and are trained to work with R-410A, R-22, R-32, R-454B, and all other regulated refrigerants found in residential and light commercial systems. Whether your AC is a 2-ton window package unit or a 5-ton split system, a 20-year-old R-22 unit or a brand-new inverter model, KIC Refrigeration has the diagnostic capability and parts access to repair it correctly at your Hopkinton property.

Why does my AC keep tripping the breaker in Hopkinton?

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 Hopkinton property — including megohm resistance testing on compressor windings and amperage measurements — to identify the root cause and repair it safely.

How long does AC repair take in Hopkinton?

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