Need help AC problem
 

This last Spring my AC was low on refrigerant so I tried to added more refrigerant to the system but the system wouldn't not accept any of the refrigerant I tried to add. I flushed all lines, the condenser, evaperator. I installed a new expansion valve, a new Denso compressor, a new dryer and ester oil. I then started adding 134a. refrigerant, the temperature went down to about 55 degrees, the low side was about +25 and the high side was about 125 the system again would not accept any more refrigerant and temperature started to rise to about 70 degrees at the vent. Now I am back square one. I sure need some help.

You need to properly evacuate the system.

You can actually rent a vacumm at Autozone or Kragen, for FREE.

The vacumm must hold for at least 30 minutes at negative 30 atmosphere, to insure there is no leaks and proper evacuation.
