Boiler Maintenance in Easton, PA

Boilers are patient machines. They will run for years while a small problem quietly gets worse, and then fail on the coldest night of the year. An annual service is how you find the small problem while it is still small.

Plumbing Pros services boilers across Easton, Bethlehem, Nazareth, Wilson and the Lehigh Valley, and heating and cooling across Warren County, New Jersey.

What an annual boiler service covers

• System pressure, the fill valve and the expansion tank. Pressure that keeps dropping means a leak somewhere. Pressure that climbs means the expansion tank or fill valve needs attention. Both are cheap now and expensive later
• The circulator pump and zone valves, which are the most common failures on a multi zone system and the usual reason one part of the house stays cold
• The heat exchanger, checked for scale and for cracks
• Ignition, gas pressure and combustion, analysed rather than eyeballed
• The aquastat and the low water cutoff, which is a safety device and worth testing rather than assuming
• Venting and the flue
• Air in the loops, and whether it keeps coming back, because air that returns means it is getting in somewhere

The scale problem, which is local

Hard water is common across the Lehigh Valley. In a boiler that means scale building on the heat exchanger, and scale is what causes kettling, the rumbling or banging that sounds like a kettle coming to the boil.

It is not just a noise. Scale insulates the heat exchanger, so the boiler burns more gas to deliver the same heat, and it shortens the life of the most expensive component in the system. Catching it during a service is far cheaper than replacing a boiler early.

Steam systems

Older properties around Easton still run steam, and steam needs different attention: correct pitch on the pipes, working vents, and the right water level. Tell us which type you have when you book, because it changes what we bring and how long it takes.

Between services

• Check the pressure gauge occasionally. If it is drifting, tell us before it becomes a no heat call
• Bleed radiators that are cold at the top
• Listen for kettling. A new rumble is worth a call
• Keep the area around the boiler clear
• Test carbon monoxide alarms. Any gas appliance needs working alarms, and they expire

Common questions

How often should a boiler be serviced?

Once a year, before the heating season. Most winter breakdowns were visible in the autumn.

What is that banging noise?

Most likely kettling from scale on the heat exchanger, which is common with hard water here and worth dealing with early.

My pressure keeps dropping. Is that serious?

It means water is leaving the system somewhere. Sometimes it is a simple fix, sometimes it is a leak worth finding before it does damage. Either way it does not resolve itself.

Do boilers last longer than furnaces?

Often, yes. Cast iron boilers in particular can run for decades with maintenance, which is a large part of why servicing them pays off.
