"Hi, I'm John Lewis, founder of JSL and I've been working in the HVAC industry for 18 years. I enjoy my job because of the satisfaction I get from helping people daily. I like the challenge of trouble-shooting systems to find problems and correcting them. I also enjoy installations because I am able to create an appropriate heating or air conditioning system that works for my customers. My motto is 'Service with Integrity' and that means that being honest and doing what is best for the customer is my priority. "
