I have a 4 ton a/c outside and a 3 ton coil or air handler up in my attic all goodman products. My compressor was grounded and now I being told that I need to replace everything. Two companies have came out to inspection, I just feel I am not getting the truth. I feel that they just want to make some money, they are telling my warranty company that they don't match and need to be replaced. What can I do to protect myself or get a honest answer?
