How our NATE-certified technicians deliver quality boiler repair results from start to finish.
Our Welcome 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 Welcome, SC 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 Welcome 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.
Get answers to the boiler repair questions our customers ask most often.
Boiler repair in Welcome 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 Welcome 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 Welcome quickly using combustion analyzers, pressure testing, and electrical diagnostics to identify the exact failure.
The repair-versus-replace decision depends on your boiler age, AFUE efficiency rating, and the cost of the current repair. If the boiler is under 15 years old and the repair is under $2,000, repairing usually makes financial sense. Cast iron boilers over 25 to 30 years old with cracked sections, or standard-efficiency units with AFUE ratings below 80 percent, are typically better replaced with a new high-efficiency condensing boiler rated 90 to 98 percent AFUE. A condensing boiler extracts latent heat from flue gases that older boilers waste up the chimney, saving 15 to 20 percent on annual fuel costs. KIC Refrigeration provides honest repair-versus-replace assessments for Welcome homeowners based on equipment condition rather than sales targets.
Yes. KIC Refrigeration services all types of boilers in Welcome including combination boilers that provide both space heating and domestic hot water from a single unit. We work on combi boilers from Navien, Rinnai, Viessmann, Weil-McLain, Burnham, Buderus, Baxi, and other manufacturers. Common combi boiler repairs include diverter valve replacement, plate heat exchanger descaling or replacement, flow sensor calibration, expansion vessel recharging, and ignition module troubleshooting. Our technicians carry diagnostic tools specific to combi boiler systems and understand the interaction between the heating and hot water circuits that makes these units unique to diagnose.
Our reputation is built on certified technicians, honest pricing, and results that last.
"Good experience with the furnace tune-up. Technician was thorough and pointed out a couple things to watch for. Only reason for four stars is scheduling took a few days."
"Boiler kept cycling on and off. Technician found a faulty thermocouple and replaced it on the spot. No nonsense, no upselling. Just good honest work."
"AC tune-up went well. Found a refrigerant issue I did not know about and topped it off. Fair pricing and honest work."
