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
We repair rather than replace whenever the boiler section is sound. A 30-year-old cast iron boiler with a bad circulator is a repair, not a replacement.
When replacement makes sense
Plenty of the boilers we're asked to replace have years of service left. We'd rather fix it and see you for maintenance than sell you equipment you don't need.
Questions from Dingmans Ferry 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.
