Here is a simple question, with hopefully a very simple answer re an AC system:

Is the Pressure in the evaporator, higher with the compressor ON, or with the compressor OFF?

The reason I am asking is that I have a leaking compressor, and possibly a leaking evaporator as well, and I am trying to determine which of the two components has a larger leak. I noticed that if the compressor is ON, I loose the refrigerant within 5-6 days. With the compressor, off the refrigerant lasts at least 3-4 Months, So I am trying to determine if I can get away by just replacing the compressor, without replacing the evaporator as well. At least for now

I am thinking that if the pressure in the evaporator is LOWER with the compressor ON, it will then leak even Less, so I maybe able to get away without replacing it, at least for awhile.

Thanks
