[QUOTE="3B99SVT, post: 14344930, member: 35689"] When I went through my A/C installation I called my brother-in-law when I had some short cycling. He owns a couple of tire stores and has worked on A/C systems for a long time. He said it's more critical to fill R134A to target weight instead of pressure. R12 amounts were more easily judged by pressure than R134A. I added ~1/2 lb more based on his recommendation and the short cycling went away. I did have a low pressure switch go bad before like virtual said. At least they're cheap. [/QUOTE]
