Webb Heating, Air Conditioning & Electrical has served Greensboro, Winston-Salem, High Point, and the surrounding Piedmont Triad for 47 years.

Finding reliable boiler service in Greensboro, NC starts with technicians who have real hydronic heating system service experience.

From cast-iron radiators to high-efficiency condensing systems, our technicians have expertise in handling boiler repair, maintenance, and installation for homes and businesses across the Triad.
Every boiler we service is handled by a NATE-certified technician with real hands-on hydronic heating experience.

Full-Spectrum Boiler Repair, Maintenance, and Installation

Red Flags That Your Boiler Is Struggling

Boilers are typically quiet, dependable systems. When components wear down, they give clear signs that a Winston-Salem boiler repair call is worth making before a small issue becomes a cold house.

Uneven Heating or Cold Radiators: Certain rooms or cast-iron radiators that won't warm up often mean trapped air in the lines, a stuck circulator pump, or a closed zone valve. Our technicians fix this with air vent bleeding and radiator balancing so heat reaches every room evenly.
Banging, Whistling, or Kettling Noises: These rumbling or whistling sounds happen when mineral scale or sediment builds up inside the heat exchanger, restricting flow until trapped water overheats into steam.
Unexplained Pressure Drops: Constantly having to repressurize your system usually points to a hidden leak somewhere in the piping or a failing expansion tank that can no longer regulate pressure correctly.
Puddles or Active Leaks: Water pooling around the base of the boiler or dripping from pipe connections is never something to wait out.
Pilot Light Outages: A standing pilot light or electronic ignition that repeatedly flickers out will eventually cut off your heat source altogether.

If any of these sound familiar, our heating repair team can send a technician out to find the actual cause fast.

Boiler Service FAQs

Frequently Asked Questions

How often should a residential boiler be serviced?

Most residential boilers need a full inspection and tune-up once a year, ideally before the first cold snap of the season. Triad homeowners who schedule early-autumn maintenance tend to avoid the mid-winter breakdowns that come with waiting until a system is already struggling.

Webb's Home Service Agreements build this annual check into a set schedule so it's never something you have to remember on your own.

Why is my boiler making a loud banging or kettling noise?

That sound, sometimes called kettling, usually means mineral scale or sediment has built up inside the heat exchanger and is restricting water flow. As water gets trapped and overheats in those blocked areas, it creates steam pockets that produce the banging or whistling noise. Left alone, this buildup can eventually crack the heat exchanger, so it's worth having a technician flush the system before it gets to that point.

What should I do if my boiler loses water pressure?

A boiler that keeps losing pressure and needs constant repressurizing almost always has a leak somewhere in the system or a failing expansion tank. Repressurizing it yourself is a short-term fix at best and can mask a bigger problem. Call for a diagnostic visit so a technician can find the actual source before it causes more damage.

Do you service boilers in Greensboro, Winston-Salem, and surrounding towns?
