Default Vacuum pump from refrigeration compressor questions

All over YouTube are examples of folks using either air conditioner
compressors or refrigerator compressors for vacuum pumps. I know I can
buy a Chinese 3 cfm two stage pump good for 25 microns or so for about
$160.00. I have seen these reviewed and they are pretty noisy. The air
conditioner and refrigerator compressors are much quieter. I'm not
looking for a vacuum source for vacuum chucking, but am instead
thinking of using one for vacuum infusing stuff. Like food. And also
of vacuum storage of dried foods. To do this I would stack cans in my
big pressure canner with the lids in place. Using a plastic lid I
could watch the process. I already have the plexiglass material for
the lid that's plenty stout enough for the job. If the can lids won't
retain their seal when I run them through the can sealing machine I'll
just resort back to glass. So what are the disadvantages of using a
repurposed refrigeration compressor besides getting my hands on a good
one without having to let all the refrigerant out into the atmosphere,
which I am not willing to do.
Thanks,
Eric
