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.
Common problems and warning signs
- 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
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
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.
Questions from Akenac 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.
