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
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.
Repair or replace?
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.
