We recently had Corley install a new electrical system and HVAC system in our house. The technicians' work demonstrates a level of professionalism and pride that only people who love what they do and are good at it possess. We felt comfortable asking as many questions as we wanted and the technicians were patient, honest and good at explaining options. One area of opportunity I can recommend is to the office staff. While they are all very personable, we have a billing issue that has not been resolved after two telephone conversations. While I believe it can and will be resolved, when someone says they will get back to me in a certain amount of time, I expect them to.
