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 Swanzey, NH 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 Swanzey 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.
Everything you need to know before scheduling boiler repair for your property.
Boiler repair in Swanzey 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 Swanzey property so you can make an informed decision.
We recommend annual boiler service in Swanzey 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.
Most boiler repairs in Swanzey 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. KIC Refrigeration provides an accurate time estimate before starting work at your Swanzey property so you can plan accordingly.
