Our History & Our Owner

Mike Causevic has run Oasis Heating and Cooling since its inception in 1994. He had worked as an HVAC specialist for the Museum of Science and Industry and for several independent HVAC contractor outlets.

Tired of what he felt was poor customer relations, Mike started Oasis based on the promise of providing the best service possible at lower prices than his competitors. Since then, Oasis has flourished and expanded, with a history of hundreds of happy customers, a fleet of new vehicles, a growing crew of professional HVAC specialists, and a new northside Chicago office.

Our technicians are some of the best trained in the business. We consistently get rave reviews for the promptness and professionalism, many of which you can find here on our site or at Service Magic.
