About Us Mannix Heating & Cooling was founded by Jerry Mannix in 2010. At the time, Jerry had worked for one of the largest heating and cooling companies in the country. During the many years with this company, Jerry watched this company grow from a large local company to a massive nationwide consortium that grew mainly by acquiring smaller companies.

Their motto was “we are a sales and marketing company that just happens to sell HVAC equipment”.
