Our proven process ensures your boiler repair project is done right the first time.
Our Grand Blanc 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.
KIC Refrigeration diagnoses boiler problems in Grand Blanc, MI using combustion analysis data. We measure flue gas CO below 100 PPM air-free, verify oxygen levels between 4 and 8 percent, check that stack temperature is within 100 to 200 degrees of supply water temperature, and calculate AFUE to identify efficiency losses.
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.
Our Grand Blanc 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.
Everything you need to know before scheduling boiler repair for your property.
Boiler repair in Grand Blanc 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 Grand Blanc property so you can make an informed decision.
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 Grand Blanc quickly using combustion analyzers, pressure testing, and electrical diagnostics to identify the exact failure.
Most boiler repairs in Grand Blanc 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.
