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
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
If replacement is warranted we'll walk you through cast iron versus condensing, and be honest about whether a high-efficiency boiler suits your existing radiators and piping.

- Yes — steam and hot water, gas, propane and oil-fired.

- It needs looking at. Usually it's the expansion tank or a fill valve feeding water in. Shut it down and call us.
