Why Is My Boiler Making Banging Noises?

Banging or kettling sounds from a boiler are often caused by mineral buildup on the heat exchanger, trapped air in the lines, or low water flow. In steam systems, banging can also come from water trapped in pipes that are not pitched correctly. Persistent noise should be checked, since it can signal overheating and reduced efficiency.

What Are the Signs My Boiler Needs Repair?

A boiler needs repair when radiators or baseboards stay cold, the pressure gauge reads too high or too low, or you hear banging, gurgling, or kettling noises. Water leaking around the boiler or relief valve, a pilot light that keeps going out, and higher heating bills are also warning signs. Early repair helps prevent damage to the heat exchanger and surrounding floors.

Should I Repair or Replace My Boiler?

Replacing a boiler usually makes sense when it is more than 15 to 20 years old, has a leaking heat exchanger, or needs costly repairs more than once a season. A newer boiler with a failed pump, valve, or control is often worth repairing. Aire Serv of Kansas City North prices both options upfront, and new installations come with a warranty and financing options.

What Should My Boiler Pressure Be?

Most residential hot water boilers run at roughly 12 to 15 psi when cold and about 20 to 25 psi when hot, though the right range depends on the system and the height of your home. Pressure that keeps dropping may signal a leak, while pressure near 30 psi can trigger the relief valve. A technician can test pressure and expansion tank operation.

What We Check During a Boiler Repair

A boiler repair visit with Aire Serv of Kansas City North starts with an inspection of the entire heating loop, not just the boiler cabinet. Your technician checks system pressure, the circulator pump, expansion tank, relief valve, and zone valves, then inspects the burner, ignition components, and venting. They also look for leaks at fittings, radiators, and baseboard connections. Once the cause is found, you receive a plain explanation and an upfront repair price. After you approve, the repair is completed and the boiler is fired and monitored to confirm steady pressure, proper ignition, and heat reaching every zone. If the boiler is near the end of its life, Kansas City homeowners can compare a replacement price before deciding.
