We inspect the boiler for visible damage, check the pressure gauge and temperature readings, test safety controls including the pressure relief valve and low-water cutoff, and verify the flue is drafting properly before diagnosing the fault.
KIC Refrigeration diagnoses boiler problems in Hayward, CA 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.
Our Hayward 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.
After repair, we pressurize the system, check for leaks at every connection, purge air from the zone loops, verify the expansion tank pre-charge, and run the boiler through a full heating cycle to confirm proper operation and safety control function.
