    Reliable Boiler Repair Service

    Our boiler repair services are fast and reliable to ensure that your household has a steady supply of hot water during the cold winter months.

    Here are the most common boiler defects:
    • A build-up of minerals: Such as calcium, magnesium, or hard water can damage your boiler. Mineral deposits cause loud banging noises and increase the risk of leaks.
    • Boiler leaks: May indicate corrosion in your boiler tank. If the leak comes from the pressure valve or pump, we have to repair or replace these components.
    • Pilot light or electronic ignition problems: Prevent you from lighting the main burners that heat the water.
    • No heat: Can be the result of many different causes. In most cases, a pilot light, safety switch, or broken thermostat is to blame.

    Do You Need a Boiler Replacement?

    Older boiler systems have efficiencies ranging from around 60% to 70%, where a modern unit can have energy efficiency as high as 99%. If your boiler is old and inefficient or has an oversized capacity, we will typically recommend a replacement.

    Low winter temperatures in Downers Grove, IL means investing in a system with the highest efficiency usually makes financial sense.
