Joseph was very professional and persistent in tracking down a problem he found during the test phase of the call. To find the burnt wire on the bottom of the compressor he had to dis-assemble much of the outside unit, climb into it, and work upside down to see and reach the wire's connection. This is a larger and tall 5 ton unit with 2 compressors. He kept me informed on what he was doing and what was not functioning properly. Very professional. The system is now working great.
