Should I go up to 2 1/2, My condo is about 900 square feet and I'm in the middle floor of a three story building. Refrigeration line is about 40feet.

No.
It would probably lock out in heat mode.
Get quotes on units that can use a 5/16 line.

Last question. Would it help at all to run the 3/8 where it can be put, leaving about 10 feet of 5/16 since diameter seems to have a dependence on length of run.
