I have a new Classic AC unit in my 69 and recently tried to charge the system myself. The system held a vacuum at least a day or more. I then ran the vacuum pump for a hour and then charged it using the small cans. I got about 25 pounds in low side with engine running but the temp blowing out vent was about 58 degrees. There was no air going across the coil and the garage was well over 90. The high pressure side was only about a 100 and i thought it should be 150. Do i have to add to high side and can i still use little cans or do i need the big cans====Thanks
