How our NATE-certified technicians deliver quality boiler repair results from start to finish.
KIC Refrigeration starts every boiler repair in New Lenox, IL 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.
We use a combustion analyzer to measure flue gas temperature, CO levels, O2 percentage, and stack draft. These readings tell us if the burner is firing efficiently or if the heat exchanger, burner assembly, or gas valve needs attention.
Our New Lenox technician repairs the boiler using manufacturer-specified replacement parts. Whether the issue is a failed circulator, a cracked heat exchanger section, a stuck zone valve, or a malfunctioning aquastat, we install the correct part and verify proper operation.
KIC Refrigeration verifies every boiler repair in New Lenox, IL 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.

Boiler repair in New Lenox typically costs $200 to $700 for common component failures like thermocouples, aquastats, zone valves, circulator pumps, and expansion tanks. Ignition control module or gas valve replacement runs $300 to $800 depending on the boiler manufacturer. Heat exchanger replacement is the most expensive repair at $1,500 to $4,000, varying by boiler type — cast iron sectional, copper fin tube, or stainless steel condensing — and BTU input rating. KIC Refrigeration provides a detailed written estimate with itemized parts and labor costs before beginning any boiler repair at your New Lenox property so you can make an informed decision.
We recommend annual boiler service in New Lenox before the heating season begins, ideally in early fall. A professional boiler tune-up includes a combustion efficiency analysis measuring CO parts per million, oxygen percentage, and stack temperature. The technician cleans the heat exchanger surfaces, checks and adjusts the expansion tank pre-charge pressure, tests all safety controls including the pressure relief valve and low-water cutoff, inspects the venting system for blockages or deterioration, verifies system pressure and bleeds air from zone circuits, and checks all zone valve and circulator pump operation. Annual maintenance extends equipment life by 3 to 5 years and catches small problems before they become expensive failures or emergency situations.
Most boiler repairs in New Lenox take 1 to 3 hours during a single service visit. Circulator pump and zone valve replacements are typically completed in 1.5 to 2 hours including system draining and refilling. Aquastat and control board replacements take 1 to 2 hours. Gas valve replacement takes 1 to 2 hours plus a combustion analysis to verify proper operation. Heat exchanger replacement is the most time-intensive job at 4 to 8 hours depending on whether the boiler has cast iron sections or a sealed stainless steel exchanger. KIC Refrigeration provides an accurate time estimate before starting work at your New Lenox property so you can plan accordingly.
