Pretty good A/C info forum at http://www.ackits.com/forum/index.cfm

Lots to be learned just by lurking, and you can post questions too.

hi there i hope to get these items soon. try a search for the readings they change with outside temperature. the library has books on this also. i have found that adding freon very very slowly makes for a better job. thats my experience.

I have the gages and set up also a little experience and 9 months of schooling on HVAC. Drawing and holding a vacuum for at least 2 hours is, IMO, most important. One cannot have any costly leaks..

Harbor Freight sells an air powered vaccum pump for $10, regular electric pumps run $100 -$200..
I wonder is this $10 pump is any good..
