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.
What we usually get called for
- 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
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.
When replacement makes sense
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 Westfall Township 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.
