How our NATE-certified technicians deliver quality boiler repair results from start to finish.
KIC Refrigeration starts every boiler repair in Lodi, CA 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 Lodi 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 Lodi, CA 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 Lodi 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 Lodi property so you can make an informed decision.
We recommend annual boiler service in Lodi 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.
Yes. KIC Refrigeration provides 24/7 emergency boiler repair throughout Lodi and surrounding California communities every day of the year. A failed boiler in cold weather is a serious emergency — indoor temperatures can drop rapidly, putting water pipes at risk of freezing and bursting within hours. Frozen pipes cause thousands of dollars in water damage when they thaw. Our emergency crews are dispatched with the most commonly needed boiler parts — igniters, thermocouples, circulator pumps, zone valves, and control modules — to restore heat at your Lodi property as quickly as possible. Call our emergency line and we will have a technician on the way immediately.
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 Lodi quickly using combustion analyzers, pressure testing, and electrical diagnostics to identify the exact failure.
Our reputation is built on certified technicians, honest pricing, and results that last.
