Marco Lopez inspected and diagnosed my AC unit’s problem and determined that I was not getting any cool air circulation because of a dysfunctional fan motor. After locating a new part, he installed it the next day. In addition, he inspected and cleaned my compressor. He was very professional and courteous.
