Albert Izzo, Founder

Zonatherm was founded in 1969 by Albert Izzo. His desire was to represent manufacturers in the Chicagoland area and be able to service everything he sold. With that idea in mind, he also founded Zonatherm's sister company, ThermFlo, the same day. ThermFlo would be a mechanical and electrical contracting company and have the capabilities to install and service all the equipment that Zonatherm sold. With a sales company, Zonatherm, and service company, ThermFlo, under one roof, Al’s business flourished, and in 1994, he bought a 30,000 square-foot building in Wheeling, Illinois, a northwestern suburb of Chicago. In 2002, Zonatherm became the exclusive industrial dealer for Generac standby generators in the greater Chicagoland area. In 2016, the companies began construction of its new headquarters in Buffalo Grove, IL, where both Zonatherm and ThermFlo currently reside.

That brings us to today. While Al Izzo blazed the trail 50 years ago, his son, Stephen Izzo,  has continued Al’s pursuit of excellence by ensuring Zonatherm remains the best in the industry. Our goal is to support and provide our customers with the best products and technical services available.  By providing product satisfaction and reliability, we at Zonatherm, strive to promote sound and profitable operation of our customer’s businesses. We accomplish these goals through an outstanding team of associates, whose in-depth training and industry experience ensure that our customer’s needs are met, before, during, and after our systems are installed and fully functional.
