From initial contact to final verification — here is how we handle boiler repair.
Our Des Moines 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 Des Moines, WA 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 Des Moines 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 in Des Moines 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.

Yes. KIC Refrigeration provides 24/7 emergency boiler repair throughout Des Moines and surrounding Washington 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 Des Moines 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 Des Moines 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.
