Location: Nashville
Three-Year Growth: 315.3%
2004 Revenue: $11.1 million
Employees: 95
Founded: 1990
What it does: Exactly what its name promises: plumbing, heating, and cooling services for homeowners and commercial clients. Why it's growing: Three years ago, the company began bidding on school projects and business doubled; last year, CEO Jimmy Hiller hired a new manager to run the heating and air conditioning department, which doubled as well. A 100% money-back guarantee doesn't hurt either. Recruiting drive: To find good plumbers, Hiller bought radio ads offering a $4,000 signing bonus and free maid service for a year. "We picked up two workers," he says. "I guess that's all you can expect." is counting down to the unveiling of Inc. magazine's Inc. 500 list with a profile a day of one of this year's honorees. See other honorees in the Inc. 500 Countdown archive, and discover new winners each business day until Oct. 19, when we reveal this year's number one company.
