Maumee Valley Heating & Air Conditioning
Here's why you should put your HVAC trust in our family.
The MVHAC Story
In June of 1965, Fred Slates, affectionately known as “Pops” or “Papa”, started the company now known as Maumee Valley Heating & Air Conditioning. He started the company out of his truck and a small garage located off of Telegraph road.
Fred was known for his generosity. He would accept whatever a customer could afford or barter with to pay for his services. He was also known for his ability to fix just about any furnace or air conditioner, and could often locate that hard to find part in one of the numerous storage locations where he kept the things he couldn’t bring himself to dispose of. Fred enjoyed helping others who needed a job or wanted to learn the HVAC business. In particular, he helped many of his nephews get a start in HVAC or other associated trades.
In 1995, Fred began transitioning MVHAC to his son-in-law Chris, and his daughter Patti Theodorou. Over the next 23 years, with the support of Patti; trusted advisor, mentor, and friend Mr. Don Caito; and the hard work of some dedicated service and installation technicians, Chris began to create the foundation for the business that remains to this day. Chris dedicated himself to mastering the trade, developing long-term personal and business relationships, and implementing a business model based on trust, quality, commitment, and doing things the right way.
Chris was an avid golfer and used his golfing weekends to foster his personal and business relationships. He was an active member of the Toledo Greek Orthodox Church and for many years was the chairman of the annual Greek-American Festival. He was devoted to his family and relished his role as Papou to his four grandchildren.
Sadly, on June 5, 2018, Chris lost his hard-fought battle with Leukemia. We miss him dearly but are confident that he and Fred would both be proud that the family-based business that they started and grew lives on.
