Get to know our management team below, and see what they have to say about life at AC Pro.

Dion Quinn - President
DionAc Pro Quinn

DionAc Pro Quinn began his working career in the insulation industry in 1980. In 1985, he started Material Supply, Inc. (MSI). MSI began out of a small garage in Anaheim, California as a contracting company focused on commercial and industrial insulation. A year later, the company moved into selling heating and air conditioning products and has grown to be one of the premier heating and air conditioning distributors in the country. Dion’s experience as a contractor has given the company valuable insight into what a contractor wants from a distributor. Contractors want large inventories, great showrooms, reasonable prices, knowledgeable staff that genuinely care, great contractor programs, and a distributor with integrity in all matters. This insight has guided the company since its inception, and it is what makes AC Pro stand out as an ideal business partner. In 2002, Dion and his wife Petra founded God’s Kids, a non-profit organization to improve the lives of orphans around the globe by providing shelter, food, education, and a loving environment.
