So it's been about a year since I had a tech out from George Brazil. My AC quit and had no idea why. It is an old Carrier unit but built like a tank. The tech inspected the unit on top of my roof. His final assessment was that the fan motor was bad. He insisted that the unit was so old I should consider replacing the whole system. I went over basic numbers and received his contact info. I scheduled another company for a second opinion but decided to take a look for my own curiosity. I propped the ladder and climbed on top of the roof. Upon a very basic inspection, (I do not know much about an AC unit) plain as day I can see the ground wire has deteriorated. All that was necessary, was to use the existing ground wire and just strip it back. It literally took 5 minutes. I reconnected the newly stripped ground wire and boo yah, the unit was purring like a kitten. I cancelled the scheduled tech from the other company and enjoyed conditioned air again. I complained to customer service of George Brazil and asked why their qualified techs were able to make such a poor assessment of the status of my AC. All they could respond with was an apology and a comped dinner and movie. The only issue with this response is they never even sent over my dinner and a movie compensation. TLDR do not trust these guys. They are just glorified salesman trying to push service with no consequence. Buyer beware.
