If your boiler is running but rooms stay cold, the issue could be a faulty pump, airlocks in the system, zone valve failure, or thermostat problems. We diagnose and fix the root cause quickly.
Water leaking from your boiler can indicate a broken pressure relief valve, corroded pipes, pump seal failure, or a cracked heat exchanger. Left untreated, leaks cause serious damage — call us immediately.
Unusual sounds from your boiler usually signal lime scale buildup, trapped air, or a failing pump. Our technicians identify the exact cause and perform the appropriate repair to restore quiet, smooth operation.
A boiler that won't ignite or has a repeatedly failing pilot light often points to a faulty thermocouple, blocked pilot jet, or gas supply issue. We safely diagnose and repair all ignition-related problems.
Incorrect boiler pressure prevents proper heating and can damage components. Whether your system shows low pressure due to a leak or high pressure from a faulty valve, we'll calibrate and repair it correctly.
Frequent boiler lockouts indicate an underlying fault with sensors, pressure, or ignition. Instead of repeatedly resetting the unit, let our technicians diagnose the actual problem and fix it permanently.
Chicago winters frequently cause condensate pipes to freeze, blocking the boiler and triggering a lockout. We safely thaw frozen pipes and advise on insulation solutions to prevent recurrence.
Modern boilers display fault codes when something goes wrong. Our technicians are trained to interpret error codes across all major brands and take the correct corrective action.
