What boiler repair involves
A boiler that fires but doesn't heat is a distribution problem. A boiler that won't fire is a control or fuel problem. We separate the two before quoting anything.
Hot water and steam boiler troubleshooting — circulators, zone valves, aquastats, low-water cutoffs and leaks.
Signs you need service
- One zone stays cold while the others heat fine
- Banging, knocking or gurgling in the pipes
- Pressure gauge reading too high or dropping steadily
- Water on the floor around the boiler
- Boiler runs constantly without satisfying the thermostat
The repair itself
After any hydronic repair we purge air from every zone and confirm each one comes up to temperature — that step is skipped more often than any other.
Repair or replace?
A leaking boiler section, a cracked block, or repeated flooding on a steam system are the real reasons to replace. We'll show you which one applies.
