However, it is their commitment to the AC Pro mission of caring for people that makes them successful leaders.

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

Dion Quinn - President
Dion Quinn

Dion 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.

Greg Lovoy - Sales Manager
Greg Lovoy
Sales Manager

Greg Lovoy is responsible for leading the team of sales associates for the Southern California area. Greg has been in the HVAC industry for approximately 34 years. Fifteen of those years was spent in his family’s HVAC business in the area of sales, bidding and estimating. He says, “I had the privilege of working as a territory manager for eight years when AC Pro was known as MSI HVAC. I spent the last ten years working as a Contractor Development Specialist for Honeywell training and selling controls and IAQ products to Southern California contractors. What I enjoy most about AC Pro is the way they treat their customers. You see, I’ve had the privilege of being both a customer and an employee of AC Pro. As a contractor in the early 90’s, I had found no other wholesale distributor who took such a genuine interest in the success of our business, then AC Pro. At that time, they had helped tailor an estimating program that streamlined the process and enabled more productivity. Today our customers will find new and innovative ways to take care of their business from streamlining the order process through the Online Store to Managed-Inventory programs for truck and warehouse stock. The AC Pro difference is found in the depth and quality of the services we provide our customers. Time and time again I’ve seen our associates go the extra mile to fulfill their mission in giving the best customer experience possible because at the end of the day, we don’t just strive to be a company that values success, but rather, be a company that provides value to their customers to help them achieve their success.”
