Your Boiler Stopped Working. You Need SomeoneWho Actually Knows What They're Looking At.
A boiler system that stops heating — or starts behaving strangely — is not the time to call a plumber who learned about boilers on YouTube. Hot water and combination boiler systems are complex, and diagnosing them correctly requires hands-on experience with how these systems actually work. Getting it wrong means misdiagnosis, unnecessary parts, and a system that still doesn't heat properly after you've paid for the work.
The Boiler Systems We Service
Common Boiler Problems We Diagnose & Repair
-
No HeatThe most urgent boiler complaint. Could be a failed circulator pump, a faulty zone valve, a tripped pressure relief valve, an ignition failure, a failed control board, or a number of other causes. We diagnose the specific failure before recommending any repair — not guess and replace parts until something works.
-
Boiler Firing But No Heat at Radiators or BaseboardsIf your boiler is running but heat isn't reaching your rooms, the problem is almost always in the distribution system — a failed circulator pump, an air-locked system, a closed zone valve, or a blockage in the piping. We trace the problem to its source.
-
Low Boiler PressureLow pressure in a hot water boiler system is usually caused by a water leak somewhere in the system — at a radiator valve, a pipe joint, or the boiler itself — or a failed expansion tank. We locate the source of the pressure loss and address it properly.
-
Boiler Pressure Too HighExcessive pressure usually indicates a failed expansion tank or a filling valve that won't close. Left unaddressed, high pressure will eventually trip the pressure relief valve — and a pressure relief valve that keeps tripping is a system that needs immediate attention.
-
Boiler Keeps Shutting OffA boiler that cycles on and off frequently — called short cycling — wastes fuel, accelerates wear on components, and usually indicates a problem with the heat exchanger, a flow issue, an oversized unit, or a control system malfunction.
-
Pilot Light or Ignition ProblemsOn gas-fired boilers, ignition failures prevent the burner from firing. Failed igniters, dirty flame sensors, faulty gas valves, and pilot assembly issues are all common causes we diagnose and repair.
-
Strange Noises — Banging, Kettling, GurglingBanging or kettling sounds from a boiler usually indicate limescale buildup on the heat exchanger, air in the system, or a circulation problem. Gurgling points to air in the pipes. We identify the specific cause and address it correctly.
-
Leaking BoilerWater around or beneath a boiler can come from a failed pump seal, a corroded pipe joint, a failing heat exchanger, or a pressure relief valve that's discharging. Location of the leak determines the repair — we find it before recommending a fix.
-
Boiler Running ConstantlyA boiler that won't shut off is usually a thermostat or control issue, a zone valve that won't close, or a sensor failure. We trace the control circuit and identify the fault.
