A clear, step-by-step approach to every boiler repair project we take on.
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.
At your Lexington property, our technician tests combustion efficiency with a calibrated analyzer. We measure CO parts per million, oxygen percentage in the flue, stack temperature, and calculate combustion efficiency. Readings outside manufacturer specs point directly to the failed component.
KIC Refrigeration repairs boilers in Lexington, VA 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.
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.
Common questions about boiler repair costs, timelines, and what to expect.
Boiler repair in Lexington 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 Lexington property so you can make an informed decision.
Boiler pressure loss indicates a leak somewhere in the sealed system. The most common causes are a failed expansion tank bladder that allows air into the system, leaking zone valve packings, corroded pipe fittings or baseboard connections, a weeping pressure relief valve, or a pinhole leak in the heat exchanger itself. A healthy hydronic system holds 12 to 18 PSI when cold and rises to 18 to 25 PSI at operating temperature. If the pressure gauge drops below 10 PSI, the low-water cutoff should shut the burner down to prevent damage. KIC Refrigeration pressure-tests the system, inspects all fittings and valves, and locates the leak at your Lexington home so we can repair it permanently.
Yes. KIC Refrigeration provides 24/7 emergency boiler repair throughout Lexington and surrounding Virginia 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 Lexington 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 Lexington quickly using combustion analyzers, pressure testing, and electrical diagnostics to identify the exact failure.
