Tim was tremendous, both in making the diagnosis and explaining it to us along with the best next steps to solving it. His repair was efficient and effective, which got the system up and running quickly for us. Tim was timely and extremely courteous. Fred was also outstanding in his support and care for us as customers of Rocky Top and Shannon also was great, as she has been many times in the past. They all exceeded our expectations in handling the issue with our unit and we cannot be more pleased and thankful.
