Technicians are required to pass difficult exams, drug tests, and undergo training in professionalism. Indeed, not every plumber is created equal and those plumbers with the most training tend to be the best. "When folks call a plumber or a mechanic to service their air conditioning or plumbing system, they already assume the job will be completed correctly and professionally. Failing to live up to that expectation is an easy way to lose customers and harm your reputation. That is why at Parker and Sons we emphasize customer service from day one. In our industry it can make all the difference," said Josh Kelly of Parker & Sons.
