What boiler repair involves
A boiler that fires but doesn't heat is a distribution problem. A boiler that won't fire is a control or fuel problem. We separate the two before quoting anything.
Hot water and steam boiler troubleshooting — circulators, zone valves, aquastats, low-water cutoffs and leaks.
Common problems and warning signs
- Steam boiler flooding or losing water quickly
- Whistling or hissing air vents
- Rust staining below the boiler jacket
- Short cycling on the aquastat
- Domestic hot water off a boiler coil running lukewarm
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
A leaking boiler section, a cracked block, or repeated flooding on a steam system are the real reasons to replace. We'll show you which one applies.
Questions from Branchville homeowners
- Why is only one zone cold?
- Most often a stuck zone valve, a failed circulator, or trapped air. All three are common repairs.
- Can an old boiler still be efficient?
- A well-maintained cast iron boiler with correct controls can be quite serviceable. Age alone isn't the deciding factor.
