Is there a way to build/connect the following items to an AC system
and have it evacuate all of the refrigerant.
1. Manifold gauge set
2. 2cfm 2-stage vacuum pump 110v
3. emty propane tank.
My understangin is that the commercial units costing $4,000
essentially are built fromthe same components.
I have no plans to reuse the old 134a. All I want to do is
depressurize the system so that I can replace a bad compressor.
