Not trying to hack the thread but quick question. My ac system has probably less than an ounce to no refrigerant in it. I'm gonna recharge it this week. When I go to jump the plug, the compressor kicks on and squeals or squeaks then shuts off. Is that because there is no refrigerant in the system to lube it to help it run smoothly? Or is the squeak bad?

I lived through that crazy heat wave here last summer with 100+ temps for weeks at stretch. Not anyone's idea of a good time...

So when my low gauge hits 45 the compressor will kick on. The high side will go to 150, but then the low side will drop and the compressor kicks off. When it does kick on it kicks right back off. The cycles starts over. Lows side hits 45 and kicks compressor on, as this happens the high side goes to 150 but the low side drops again and the compressor kicks off. Over and over and over.........
