Both times that Tim's Air Conditioning have been out I would give them a five-star rating for service! They were on time and very knowledgeable. We had some issues with the gas furnace. The first time they came out they were able to replace a part but then the furnace failed again and they came back out and now the fan needs to be replaced. Not the same part as replaced the first time, and not their fault another part went out. I do like this service and I will continue to use them.
