From initial contact to final verification — here is how we handle boiler repair.
KIC Refrigeration starts every boiler repair in Greenville, NC with a thorough safety and operational inspection. We verify that the pressure relief valve releases at its rated pressure, the low-water cutoff shuts the burner down when water level drops, and the high-limit control prevents overheating. Safety is always the first step.
At your Greenville property, our technician tests combustion efficiency with a calibrated analyzer. We measure CO parts per million, oxygen percentage in the flue, stack temperature, and calculate combustion efficiency. Readings outside manufacturer specs point directly to the failed component.
We replace the failed component — circulator pump, expansion tank, zone valve, aquastat, gas valve, ignitor, or heat exchanger section — using parts rated for your boiler make, model, and BTU capacity.
KIC Refrigeration verifies every boiler repair in Greenville, NC by running a complete system test. We confirm operating pressure is stable, all zones circulate properly, combustion readings are within specification, and every safety control responds correctly. We document all final readings for your records.

Warning signs that your boiler needs professional attention include radiators or baseboard that heat unevenly or stay cold in certain zones, banging or kettling noises caused by scale buildup or air in the system, the pressure gauge reading below 12 PSI or above 25 PSI, visible water leaks at fittings, valves, or the boiler itself, a pilot light or electronic ignition that will not stay lit, error codes flashing on the control board, and a noticeable increase in gas bills without a change in thermostat settings. Any of these symptoms warrants a professional inspection. KIC Refrigeration diagnoses boiler problems in Greenville quickly using combustion analyzers, pressure testing, and electrical diagnostics to identify the exact failure.
