David Postell started installing air conditioners in 2003, after his uncle brought him into the business. He eventually ran his own business and was subcontracting for larger firms in the Charleston, South Carolina, area. That was in 2008. Postell gave up his business to go work full-time for one of these firms. There he became installation manager and met his wife, Stephanie. The two shared a dream of starting a business, which they did. They leased a building, hired a dispatcher, and launched Hero Heating and Air.
That was at the beginning of March. A few weeks later, they let go of their dispatcher and got out of their lease. In May, another contractor sold the Postells his residential business. David Postell spent almost every day in June installing air conditioners.
