About Us

History of BEL-O

BEL-O Cooling & Heating Inc is O’Fallon’s expert heating and cooling company. We offer furnace and air conditioning services in and around O’Fallon. Please, feel free to contact us for more information on our services, products, and company.

BEL-O has been a family-owned and operated company since we opened our doors in 1959, then called Belleville O’Fallon Heating & Cooling Inc., located off North Lincoln in O’Fallon. Brothers Leo and Paul Lugge learned the value of hard work and commitment at an early age. These values have been passed on to the second and now third generation holding true to the “founding fathers” ideals.

Pride is a word that all of us take very seriously. We are proud of the work we do, and the services we perform for our customers and community. Our team at BEL-O Cooling & Heating Inc. consists of professionals from several trades. We have sheet metal workers, heating and cooling technicians, plumbers, pipefitters, design engineers, sales specialists, and customer service personnel. Many of our team members have numerous years of experience in their trades which gives us the depth of knowledge necessary to deal with a wide range of comfort requirements. Our trained technicians can care for any indoor comfort system your home or business may have, even if it is not a Carrier System. You can call us for prompt and reliable service.

We are committed to providing our people with the best training possible for today and tomorrow. This is one way we can assure you, our customer, of the quality services you have to come to expect from us.

To sum this up, “we take pride in our people because they take pride in serving you!”
