Our Boiler Repair Process

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

1

Boiler Inspection & Safety Check

KIC Refrigeration starts every boiler repair in Amherst, NH with a thorough safety and operational inspection. We verify that the pressure relief valve releases at its rated pressure, the low-water cutoff shuts the burner down when water level drops, and the high-limit control prevents overheating. Safety is always the first step.

2

Combustion & Efficiency Analysis

We use a combustion analyzer to measure flue gas temperature, CO levels, O2 percentage, and stack draft. These readings tell us if the burner is firing efficiently or if the heat exchanger, burner assembly, or gas valve needs attention.

3

Repair & Parts Replacement

Our Amherst 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.

4

System Pressure Test & Verification

KIC Refrigeration verifies every boiler repair in Amherst, NH by running a complete system test. We confirm operating pressure is stable, all zones circulate properly, combustion readings are within specification, and every safety control responds correctly. We document all final readings for your records.

Boiler Repair FAQ — Amherst, NH

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

How much does boiler repair cost in Amherst, NH?

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

What are the signs that my boiler needs repair in Amherst?

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 Amherst quickly using combustion analyzers, pressure testing, and electrical diagnostics to identify the exact failure.

Should I repair or replace my boiler in Amherst?

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 Amherst homeowners based on equipment condition rather than sales targets.

Can you repair combi boilers in Amherst?

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