Wow, I really need to not be posting at 4am.
Somehow I read the OP as being a 17 year old Goodman 2 speed unit!
Now I see that it is a 1 year old unit, which is a COMPLETELY different animal than the old mid 90's Goodman 2 speed units, so ignore most of my last reply.

Yes, the 3rd port is the true suction pressure for the compressor, and is the same pressure acting on the units low pressure switch.
If more government is the answer, then it's a really stupid question.
I returned to the heat pump today and replaced the txv, filter/drier, and contactor(spider problem). After adjusting the spring on the txv, it seems to be working decently. I would say that the problem is solved and I can invoice the client.
The system is not working as well as it should be though. It is a 16 SEER unit and is using a fixed orifice rather than a txv at the evaporator. The furnace is not moving the desired 2000 cfm due to single point entry of return air(on the motor side to make things worse).
That being said, I was hired to fix it. I wasn't hired to point out all the mistakes made by the installer, since he is the one who hired me
Thank you for all your help. I have learned much from this experience.
