What boiler repair involves
We diagnose hydronic systems by pressure, temperature and flow — where the heat is going and where it stops. That's how you find an airlocked zone or a dead circulator instead of replacing parts blind.
Hot water and steam boiler troubleshooting — circulators, zone valves, aquastats, low-water cutoffs and leaks.
What we usually get called for
- 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
How we repair it
Circulators, zone valves, aquastats, expansion tanks and air eliminators are the usual repairs, and most are same-visit work. Leaks get traced to the fitting rather than patched blindly.
If it's time for new equipment
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.
Questions from Hawley homeowners
- Do you work on steam boilers?
- Yes — steam and hot water, gas, propane and oil-fired.
- My pressure keeps climbing. Is that dangerous?
- It needs looking at. Usually it's the expansion tank or a fill valve feeding water in. Shut it down and call us.
