Common Boiler Problems We Repair

Our experienced technicians are trained to diagnose and repair a wide range of boiler issues, including:

• No Heat or Insufficient Heat: If your boiler is running but not producing enough heat, or producing no heat at all, we quickly identify whether the issue is with the burner, thermostat, zone valves, circulator pump, or another component.
• Water Leaks and Drips: Boiler leaks can cause water damage, corrosion, and system pressure problems. We locate the source — whether it's a faulty valve, corroded pipe, or failing pump seal — and repair it promptly.
• Unusual Noises (Banging, Kettling, Whistling): Strange noises from your boiler often indicate limescale buildup on the heat exchanger, pump problems, or air trapped in the system. We diagnose and resolve the root cause.
• Pilot Light or Ignition Failures: A boiler that won't ignite or whose pilot light keeps going out requires immediate attention. We repair gas valves, ignition electrodes, thermocouples, and control boards.
• Pressure Problems: Both high and low boiler pressure can cause system issues. We diagnose pressure-related problems and repair expansion tanks, pressure relief valves, and filling loops.
• Frozen Condensate Pipe: During Chicago's coldest winters, condensate pipes on modern boilers can freeze, causing the boiler to shut down. We safely thaw and insulate the pipe to prevent recurrence.
• Thermostat and Controls Issues: Faulty thermostats, zone controls, or programmer failures can prevent your boiler from operating correctly. We repair or replace all types of heating controls.
• Radiator Problems: Cold spots, radiators not heating up, or imbalanced heat distribution are signs of circulation problems, blocked radiators, or air in the system. We bleed radiators and flush systems as needed.
• Error Codes and Lockouts: Modern boilers display fault codes when they detect a problem. Our technicians are trained to interpret all boiler error codes and perform the necessary repairs.
• Heat Exchanger Problems: A cracked or corroded heat exchanger is a serious issue that can lead to carbon monoxide leaks. We thoroughly inspect heat exchangers and advise on repair or replacement options.
