🛠️ Common Boiler Problems We Repair

Our technicians are trained to diagnose and repair all types of boiler problems quickly and effectively. Common issues we fix include:

• No Heat or Insufficient Heat: If your boiler runs but doesn't produce adequate heat, we diagnose the cause — from faulty thermostats to heat exchanger issues — and restore full heating capacity.
• Boiler Not Turning On: Ignition failures, power supply issues, or thermostat problems can prevent your boiler from starting. We identify and fix the root cause quickly.
• Water Leaks and Drips: Leaking water from your boiler can cause structural damage and efficiency loss. We locate and seal all leaks, replacing damaged seals, valves, or pipework as needed.
• Strange Noises (Banging, Whistling, Gurgling): Unusual noises often indicate air in the system, limescale buildup, or a failing pump. We diagnose and resolve noise issues promptly.
• Low Boiler Pressure: Low pressure prevents your boiler from functioning properly. We identify the cause and restore correct operating pressure.
• High Boiler Pressure: Dangerously high pressure is a safety concern. We safely reduce pressure and identify the underlying cause.
• Pilot Light Problems: A pilot light that keeps going out or won't light indicates a thermocouple issue, draft problem, or gas supply problem — all of which we resolve.
• Frozen Condensate Pipe: A common Chicago winter problem — we safely thaw frozen pipes and insulate them to prevent recurrence.
• Radiators Not Heating: Cold spots in radiators can be caused by air locks, sludge buildup, or circulation problems. We perform power flushing and bleeding to restore even heat distribution.
• Boiler Lockout/Error Codes: We interpret and resolve all manufacturer error codes across all boiler brands, resetting your system and fixing the underlying fault.
• Pump and Circulator Failures: A failed pump means hot water isn't circulating. We repair or replace pumps and circulators quickly to restore normal operation.
• Gas Valve Problems: Faulty gas valves affect combustion and safety. Our technicians are licensed to diagnose and replace gas valves safely.
