Tools for A/C work

[Bernie Benz]

Kneale,
 I use an old refrigerator compressor as a vacuum pump for system pump down,
cheap!  I'm not sure that you need gauges either, after pumping it down if
necessary, just add refrigerant until the evaporator return line is cool.
If it frosts up, you've added too much.
