Sub Zero Refrigeration has been proudly servicing the Chicago land area for forty years.  The company got its start when President Bud Wagner decided to take onthe American dream of starting a business and hiring employees.  
      
      When Bud steps out of the captain’s seat at Sub Zero he also enjoys movies and woodcarving.  His wife Sally and sons Tim and Ted know first hand what a hard working, loyal and dedicated person Bud is.  He is driven by quality and requires his technicians to be well versed in all phases of the business.

       Our family owned and operated company has enjoyed working with such loyal clients as the Village of Midlothian, Lee and Eddies Catering, S&T Provisions, M&G Provisions, Pancho Foods and Gas City over the years.      

       With an A+ rating we are proud members of the Better Business Bureau and have been accredited since 1985.  We are also proud members of the Air Conditioning Contractors of America where Bud Wagner was the Chapter President back in 1988.   

        An interesting fact about Sub Zero Refrigeration is we have employed so many excellent people over the years that we literally lost count of them.      

        Sub Zero is a Manitowoc Ice Machine Factory Authorized service and installation company.  We are also a Mitsubishi Diamond Dealer.      

        We participate in the ComEd Central Air Conditioner Efficiency Program meaning we have purchased thousands of dollars of test equipment to maximize the efficiency of your air conditioning system to bottom line save you money on your electric bill every month.  This program has been in effect for two years now.   
        What sets Sub Zero Refrigeration Heating and Air Conditioning apart from other companies is not only the quality of our work but also the specialized fields we support such as Refrigeration, Heat Pumps, and Ice Machines that other contractors are not interested in working on.  

        We have six skilled technicians which can provide any type of services for your company or residence.
