Common Boiler Problems We Solve
Most boiler problems trace back to one or two components — not the entire system. Here are the issues we fix most often for our neighbors across St. Joseph County:
No Heat at All
Often a failed thermocouple or igniter, a tripped high-limit switch, or a faulty thermostat cutting power to the system.
Uneven or Weak Heat
Usually a stuck circulator pump, trapped air in the lines, or radiators that need bleeding — not a failed boiler.
Banging or Kettling Noises
A boiler that bangs or 'kettles' often has limescale on the heat exchanger or trapped air. We flush and rebalance the system to restore quiet operation.
Leaking Boiler
Leaks commonly come from a failed pressure-relief valve, a corroded fitting, or the expansion tank — many are straightforward repairs, not replacements.
Low Pressure or Won't Stay Lit
Pressure that keeps dropping or a pilot that won't hold usually points to a leak, a faulty fill valve, or a bad thermocouple. We find the root cause.
Boiler Leaking or No Heat? Stay Safe First
If you smell gas, leave the house immediately and call your gas utility. For a leaking or dead boiler, switch it off at the service switch or breaker and shut the water feed valve. Then call us at +1 574 288 3351 for emergency assistance.
