Boiler repair in Chicago

Steam and hot water boilers keep many Chicago buildings warm. We repair both, along with the pipes, valves and radiators that go with them.

Signs your boiler needs repair

  • No heat or no hot water
  • Radiators cold or only partly hot
  • Banging or knocking pipes
  • Boiler shuts off by itself
  • Low pressure on a hot water system
  • Water leaking around the boiler
  • Uneven heat between floors

What we check

  • Thermostat and aquastat
  • Pressure, expansion tank and relief valve on hot water systems
  • Water level and low-water cutoff on steam systems
  • Circulator pump and zone valves
  • Radiator valves and air vents
  • Burner, ignition and flame signal
  • Flue and combustion safety
Smell gas or hear a CO alarm?Leave the home right away and call 911 and your gas utility. Don’t wait for an appointment.

Common questions

Why do my radiators bang?

On steam systems it is often water trapped in a pipe that isn’t pitched correctly, or a stuck vent. On hot water systems, trapped air is a common cause. We trace it and fix it.
