My advice, check and/or tighten your A/C drive belt.

Then check your static pressure on the low side without compressor running, should be around 80 psi or so on an 80 degree F day (rule of thumb, 1 psi per degree F).

When compressor is running, the low side should drop to around 35-40 psi.

Hopefully you'll find you simply need to tighten your A/C belt, and maybe charge your system.

Good luck!
