What boiler repair involves
Boiler repair covers circulators, zone valves, aquastats, expansion tanks, low-water cutoffs, air separators, thermocouples, gas valves and leaks. We test the whole loop, not just the appliance.
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
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.
If it's time for new equipment
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 Saw Creek 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.
