Boiler Service & Boiler Repair in the Chicago Area

Staying warm during Chicago winters is easy with a functioning boiler. But when your boiler starts acting up, you might need more than just a few extra blankets to stay comfortable. With almost a hundred years of experience in the HVAC world, Deljo Heating & Cooling has established itself as one of the premier heating and cooling companies in Chicago. So it should be the obvious choice for boiler service and boiler repair in the Chicago area.

Boilers are closed vessels that heat water into steam. The steam travels through piping throughout your home, finding its way into radiators or convectors to heat each room. As the steam cools, it changes back into water and returns to the boiler to continue the cycle.

Most boiler systems rely on a thermostat to signal when it’s time to begin heating the water to provide heat to the home. If your home is no longer producing heat properly, give us a call so that we can diagnose the issue. Our work speaks for itself. So after a single visit, we’re confident that we’ll always be your first call for boiler repair in Chicago and the surrounding areas..

Types of Boilers

Types of Boilers

There are two main types of boilers. The main difference between the two designs boils down to the location of the heat source and the water.

Firetube boilers

Firetube boilers feature a central tube filled with hot gasses from the burner. This central tube (the firetube) is surrounded by water which heats into steam via conduction and then makes it way through your home to provide heat. These boilers typically have a lower total cost of ownership and take up less space than their watertube counterparts.

Watertube boilers

As the name suggests, watertube boilers fill their central tube with water. The water heats via convection thanks to the hot flue gasses which surround the tube. Watertube boilers tend to be more efficient and can reach impressive levels of pressure. As a result, they’re commonly used in process industries.

Combi boilers

Acting as both a boiler and a water heater, combi boilers provide central heat to your home and provide hot water to taps. Combi boilers heat water on demand, eliminating the need for a storage tank. This also makes them rather efficient, only heating as needed. However, like tankless water heaters, combi boilers can struggle to simultaneously provide hot water to multiple taps.

Common Boiler Problems

Just like any other part of your HVAC system, boilers need TLC to function at maximum capacity. Many boiler-related problems develop after long periods of idleness. But problems can arise even during use. 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 repair 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.
