Commercial HVAC Installation in O’Fallon, Illinois

BEL-O Cooling & Heating can provide the following heating and air conditioning equipment for your business:

Rooftop Units

Rooftop HVAC installations are hassle-free solutions for your company. Because these units are installed on your building’s rooftop, they free up more work space. Plus, they are energy efficient and customizable.

Split Systems

Split systems are ideal for large businesses which don’t want to invest in expensive and invasive ductwork. They can increase your energy savings and reduce future utility bills drastically. Split systems also give businesses the opportunity to separately control the temperature in various areas of the building. Contact us to learn more about the installation of a split HVAC system!


Commercial boilers are a great option for providing your business with heat. Boilers use radiant heating systems to circulate water and steam throughout the building, rather than heated air. These units are extremely energy efficient because no heat is lost through leaky ductwork. Boilers are also long lasting and dependable. Call us today to discuss the installation of a boiler system and other HVAC equipment for your commercial building.


Unlike a furnace, a chiller uses water or another liquid to transfer heat from one location to another to cool the building. Businesses of all types can take advantage of the benefits chillers offer.
