Most likely it was the reversing valve. I refused to pay the company for the warranty compressor work and then later I went to them and negotiated a settlement with them even though the tech was horrible and the company was just as bad.
I installed a new Trane system through a different dealer, with life-time parts and labor. All I have to do is pay $150 once a year for the two PM service calls. This system will keep the house cool even on 98-degree days while with the Goodman the temp in the house would soar at 95-drees outside. And both systems are 13-seer.
Thanks all for the help... But you will never hear from me again. I love my Trane!!
