2001 chevy impala

air conditioning oh, boy this one when hooked up dosent seem to be taking any freon it shows alittle less than 25 lbs does it need a compressor???

Yep that’s are sure sign. Really get a second opinion.

The A/C static pressure is about 45 psi. If, and when, the compressor runs, the low side will pump down to about 20 psi. Wait a minuet while I get may A/C repair manual and check those minimum and maximum values!
