After one year of working for a company in the HVAC wholesale industry, Century's CEO and Founder Dennis Bearden decided that there had to be a better way to operate an HVAC distributorship. It was then that Dennis developed a business philosophy that has been Century's driving force: to regard employees as family and treat customers as friends with a generous amount of customer service.

This simple but powerful idea caught on; Century continued to grow and by 1995, through new store openings and acquisitions under the leadership of President Rick Luke, Century A/C Supply grew to eleven branches in the Houston and southeast Texas area.

In 1998, Century found a home in the San Antonio area after establishing Core Distributing. Not long after, in 2001, Century added Major Supply to the list of acquisitions, which then led to the opening of additional Houston area branches. With continued growth, in March 2008, Century added Johnson A/C Supply to its family and expanded into the Dallas area. Growth and expansion continued and in 2019, Century had a total of 26 locations throughout the state of Texas.

In 2020, Century A/C Supply entered into a new partnership with Rheem. Century A/C Supply has been a distributor of Ruud products in the Houston area since 1986 and its sister company, Air Management Supply, is a Rheem distributor with six locations in the Midwest. With this new alliance, Rheem has become a minority shareholder in Century A/C Supply and Air Management Supply with Dennis Bearden retaining a majority of shares. This partnership presents a strategic opportunity for long-term growth and reinforces the strong supplier relationships we have built over the last several decades. Branches within Century A/C Supply's York territory were phased into a new company, Century HVAC Distributing, owned entirely by Bearden.

Today, Century A/C boasts thirteen locations across the greater Houston area including the Houston Metro area, Lufkin, Conroe, Angleton, and Bay City.
