I greatful that my ac unit is fixed, but I don't believe it is necessary to charge $168 for splicing four wires together, which is all that was done. As I explained when I requested service, my dog had chewed through the four small wires of my unit. There was no need for a diagnostic charge, etc. I will say the gentleman that came out was very knowledgable and professional, but I don't think the price is competitive.
