Skip DIY Boiler Repair, Call the Boiler Experts at Paragon

If you aren’t a licensed boiler technician or boiler installer in Chicago, you should never attempt to install, replace, or repair a boiler on your own. Some things are best left to the professionals. While DIY projects are a great way to spend time and save money on home décor and minor home improvements, when it comes to highly specialized devices like heating boilers, hot water boilers, and condensing boilers, a DIY job could end up costing more than it saves or worse, putting your home at risk.

Our expert boiler technicians at Paragon Mechanical have the training and education necessary to make the most appropriate recommendations, to conduct the most efficient repairs, and perform the most beneficial maintenance for your boiler system. Nobody knows your boiler better than Paragon.

Common Problems

No Heat from Specific Radiators

If you notice that specific radiators are not providing heat, this could be indicative of air in the system. Call Paragon to schedule a service call.

Error Codes

If your boiler is equipped with a screen which displays codes or if it has a light which displays a series of flashes, please call Paragon to schedule an appointment to diagnose the potential error. Error codes of any kind usually indicate that system failure is imminent.

Blank Thermostat

If you notice your thermostat screen is blank or unresponsive, please first check to see if it has replaceable batteries. Older thermostats require infrequent battery replacement and the solution might be simple. If you have a smart thermostat like the Nest or Ecobee, this could mean it was installed incorrectly, it could indicate the boiler system has lost power or tripped a breaker. Call Paragon right away if you encounter a blank thermostat and the batteries have been replaced.

Water Leak

If you discover a water leak near your boiler or along the path of any boiler piping, please attempt to contain the resulting water and contact Paragon to identify and repair the leak(s). If the water is originating within the boiler itself, this may indicate a larger equipment problem.
