We, recently, had our air conditioning unit go out. This was a unit installed by the builder which was cheap to start with and poorly installed. We had had Jon Wayne come out and service it once and had been warned that it would, probably, go out within a short time. Since I am an emphysema patient and cancer patient the loss of the air conditioning on a day when the temperature hit the upper 80's was extremely distressing. The Jon Wayne technicians worked tirelessly for over 12 hours getting the new system installed and running. The workmen were unfailingly polite (something not common in today's world) and kept us informed any time we had a question. I would, definitely, recommend this company for any a/c work.
