Our Boiler Repair Process

How our NATE-certified technicians deliver quality boiler repair results from start to finish.

1

Boiler Inspection & Safety Check

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.

2

Combustion & Efficiency Analysis

At your Sunnyside 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.

3

Repair & Parts Replacement

KIC Refrigeration repairs boilers in Sunnyside, WA 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.

4

System Pressure Test & Verification

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.

Boiler Repair FAQ — Sunnyside, WA

Get answers to the boiler repair questions our customers ask most often.

How much does boiler repair cost in Sunnyside, WA?

Boiler repair in Sunnyside 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 Sunnyside property so you can make an informed decision.

Does KIC Refrigeration offer emergency boiler repair in Sunnyside?

Yes. KIC Refrigeration provides 24/7 emergency boiler repair throughout Sunnyside 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 Sunnyside property as quickly as possible. Call our emergency line and we will have a technician on the way immediately.

Why is my boiler losing pressure in Sunnyside?

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 Sunnyside home so we can repair it permanently.

Can you repair combi boilers in Sunnyside?

Yes. KIC Refrigeration services all types of boilers in Sunnyside 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.
