Joseph came to our house within an hour of being notified. His appearance was neat and very professional. I explained our problem with having no a/c and off he went to the outside unit. He immediately checked the dual capacitor and found it to be the overall problem. He replaced the bad unit and the outside unit took off running...we had a/c!! Joseph knew what he was doing and did it well. I might note that this capacitor was said to be out of tolerance in our spring maintenance routine. Why wasn't it changed out then? Again, Joseph is an outstanding employee and ars can be very proud of him.
