Today, Houston-based Haley Plumbing, Heating and Air Conditioning employs 14 people and uses eight trucks to perform mostly residential and commercial service and repair work. The Haleys identify much of their clientele as high-income households who work for technology firms, gas and oil companies and NASA. On the commercial side, the Haleys work for companies that demand perfection, such as Coca-Cola and Anheuser-Busch. "If your truck's dirty, they won't even let you on their property," Barry says.
