I didn’t do a write up of converting the stock AC compressor to an air compressor because it’s very straight forward.
Compressor needs a drip oiler on its intake that you can get at any air compressor shop and it needs a moisture/oil separator on its output to strip out the oil that gets blown...
Converted my AC compressor to an air compressor since I never used my AC. It’s faster than any of the compressors shown on this thread except maybe ties with the York.
Bonus points — no weird installation necessary. AC compressor is already installed.
I wish I had converted it decades ago .
