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.
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
The repair itself
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.
Repair or replace?
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 Rowland 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.
