You bet that helps. It sounds like your freon level is low. Therefore the compressor will only kick on for a couple of seconds and then back off. This is a built in safetly so the compressor doesn't get burned out trying to compress something that isn't there.

(Disclaimer: Last sentence was pulled outta my butt...and sounded GOOD)

That is really odd because I just had the freon fully recharged. And I can't see or hear the compressor go on or off. The only difference having the A/C on seems to have is the RPM guage, and it is barley noticable. Any suggestions?

Just because you charged the freon, doesn't mean it is still charged. You may have a leak. You need to get some guages on it, add some leak detecting flourecent dye or have someone with a "sniffer" check for leaks before you go any further.
