Our Boiler Repair Process

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

1

Boiler Inspection & Safety Check

Our Milton technician begins with a comprehensive safety inspection — testing the pressure relief valve, low-water cutoff, high-limit control, gas valve operation, and flue draft. We check boiler pressure, inspect the expansion tank, and look for signs of corrosion, leaks, and scale buildup.

2

Combustion & Efficiency Analysis

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.

3

Repair & Parts Replacement

KIC Refrigeration repairs boilers in Milton, WI with the correct parts and procedures. We match components to your specific boiler model and BTU input rating, torque all gas connections to spec, leak-test with gas detector soap, and verify the repair restores proper operation and efficiency.

4

System Pressure Test & Verification

Our Milton crew pressurizes the boiler system to 15 to 20 PSI, inspects every fitting and valve for leaks, bleeds air from all zone circuits, and runs the boiler through a full cycle — verifying ignition, flame signal, circulator operation, and temperature rise to confirm the repair.

Boiler Repair FAQ — Milton, WI

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

How much does boiler repair cost in Milton, WI?

Boiler repair in Milton 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 Milton property so you can make an informed decision.

Can you repair combi boilers in Milton?

Yes. KIC Refrigeration services all types of boilers in Milton including combination boilers that provide both space heating and domestic hot water from a single unit. We work on combi boilers from Navien, Rinnai, Viessmann, Weil-McLain, Burnham, Buderus, Baxi, and other manufacturers. Common combi boiler repairs include diverter valve replacement, plate heat exchanger descaling or replacement, flow sensor calibration, expansion vessel recharging, and ignition module troubleshooting. Our technicians carry diagnostic tools specific to combi boiler systems and understand the interaction between the heating and hot water circuits that makes these units unique to diagnose.

Does KIC Refrigeration offer emergency boiler repair in Milton?

Yes. KIC Refrigeration provides 24/7 emergency boiler repair throughout Milton and surrounding Wisconsin 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 Milton property as quickly as possible. Call our emergency line and we will have a technician on the way immediately.

What are the signs that my boiler needs repair in Milton?

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 Milton quickly using combustion analyzers, pressure testing, and electrical diagnostics to identify the exact failure.
