Common Boiler Issues We Fix

No heat or hot water

This is one of the most common boiler problems and can be caused by a variety of issues—including broken diaphragms, airlocks, motorized valve failures, or low water levels. If your boiler isn’t producing heat or hot water, it’s critical to have it inspected quickly to prevent further damage to internal components or connected radiant heating loops.

Leaking or dripping boilers

Leaks can result from internal corrosion, faulty pressure valves, or broken seals. A leaking boiler not only decreases efficiency but can also cause water damage to surrounding structures. Our technicians quickly identify the source and replace worn parts to restore safety and prevent future leaks.

Kettling (boiler making rumbling noises)

Kettling occurs when limescale or sludge builds up on your boiler’s heat exchanger, restricting water flow and causing it to overheat. This results in rumbling or banging sounds. Kettling reduces the lifespan of your system and increases energy usage. We flush the system and treat it with inhibitors to keep your boiler running quietly and efficiently.

Low boiler pressure

Low pressure often results from leaks, recently bled radiators, or a failing pressure relief valve. Boilers require consistent pressure to circulate hot water through your home. If the pressure drops too low, the system won’t operate correctly. We assess and recharge the system to optimal pressure levels.

Faulty thermostat or pilot light

When your thermostat isn’t communicating properly or your pilot light keeps going out, your boiler may shut down intermittently. This can leave you without heat when you need it most. Our techs test, calibrate, and replace faulty components to restore full control over your heating system.

Error codes or ignition failures

Modern boilers display error codes when something’s wrong—from ignition faults to circulation problems. These diagnostic codes are helpful, but a professional is needed to interpret them and resolve the underlying issue. We handle all common fault codes and get your system safely operational.

Uneven heating or radiators not warming

If some rooms are warm while others remain cold, it could be due to trapped air, clogged valves, or an imbalance in the system. We inspect each zone, bleed radiators, and fine-tune your system so heat is distributed evenly throughout your home or business.

We have a 1996 vintage radiant heating system. I called Jane’s on a freezing Valentine’s Day and Lucille found a tech immediately. Jesse arrived within 45 minutes and fixed the issue without upselling. He explained everything clearly — I now understand my system better than ever. Exceptional service!
