Boiler Service in the Chicago Area

Staying warm during Chicago winters is easy with a functioning boiler. When your boiler starts acting up, you might need more than just a few extra blankets to stay comfortable.

So, it should be the obvious choice for boiler services and boiler inspections in the Chicago area.

Servicing Your Boiler

Just like any other part of your HVAC system, boilers need regular maintenance to function at maximum capacity. Many boiler-related problems develop after long periods of idleness. It is important to have your boiler serviced once every 12 months. This ensures your boiler and pressure vessels are working the way they are supposed to.

Without regular boiler maintenance, your boiler will become less efficient. It will consume more energy, and could even burn out long before its time. This could mean higher bills, costly repairs, or the need for a whole new system.

Common Boiler Problems

There are several signs that can indicate your boiler needs to be inspected soon. Some of the most common issues that require boiler service in Chicago include:

Low Boiler Pressure

Low boiler pressure is typically a nod to a malfunctioning central heating system. As the first step to boiler service in Chicago, our team will look for leaks. If none are found, we will re-pressurize your boiler so it can work properly again.

Banging or Whistling Noises

Noisy boilers are typically the result of air in the system, low water pressure, or a faulty pump.

Intermittent Heat or Hot Water

Broken diaphragms and airlocks, faulty valves, or a broken thermostat can cause inconsistent heat or hot water. Our team will be able to pinpoint the problem to help your boiler run smoothly once again.

Ari Telisman Chicago IL.

My hot water heater had some leaky pipes due to corroded unions. The repair took longer than I thought due to some unforeseen circumstances. Unfortunately after the repairs the water heater stopped working...
