That is a good package. All the surge protection you can get is important here. I have heard central Florida is the lighting capital of the world. Ask what is covered and what monetary reimbursment you can get if the device fails. The AC companies can install a protector on the outside AC unit disconnect that will pay back up to $2000.00 if the device fails, (which I hope it dosn't). Whatever you get, make sure it covers the compressor which is the heart and most expensive part of the AC.
