If they are small recip.compressors (i.e.<4cyclinders) then speed control with a VFD will introduce a torque pulsation effect and therefore you need a high performance VFD (the 'vector' control type)to combat this if the need is there to use a VFD.
You should always consult with the manufacturer of compressor and they will advise any lubrication issues as well.

These things can be dealt with you just have to consider them.

As for my experience I have only started reciprocating compressors with VFDs. I have usually found that a VFD causes to many problems than what the savings is worth.
