At UTI he studied Air Conditioning, Heating, Solar, Electrical and Commercial Refrigeration. That training was instrumental in his ability to provide service to residential and commercial heating, air conditioning and ventilation equipment, as well as commercial refrigeration systems such as walk in refrigeration units, Freezers, Commercial Ice Machines, reach ins, meat coolers and many other refrigeration applications. In 2003, John Grisler obtained a United States Patent on his triple pass refrigeration system, which is something that is no easy task to do, considering how many refrigeration designs are out there today. That patent is a symbol of his in depth knowledge of the modern refrigeration systems and the products that most air conditioning and refrigeration system are designed after. That knowledge is your security in knowing that our experience is vast and your installation and your repair will be in good hands! You can read more about his sit and cool refrigeration system on that page.
