Probably between $4,000 to $6,000 for the entire system. But, you should get 3 written quotes before selecting a contractor. I would buy a Carrier system instead of Trane. Also, you should check the model number on your outside unit and google it to determine how many tons of cooling you currently have. It will probably be about 3 tons for the size of your house. If it is 3 tons or less, you may want to increase it by a half ton, especially if your current unit runs for a long time. Just something to consider. Chuck Farrell, 352-753-9497, is a good contractor. I would also get a quote from Munn's.
