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
- Boiler won't fire at all on a call for heat
- Radiators warm at the bottom, cold at the top
- Relief valve discharging water
- Circulator humming but no flow
- Frequent resets or a lockout that keeps returning
What the repair involves
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?
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 Childs Park 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.
