My toyota pickup used to idle faster when turning on the air conditioner, now it doesn't. I know it's controlled by the big hex screw, but turning it while the a/c is on doesn't make any difference. Is it something I can take apart and clean if need be, or do I have to change it?

What year truck?
Is the AC compressor clutch actually engaging? What is the idle RPM with and without the AC engaged?
If a/c magnet clutch is ok, then check a/c idle-up vsv.
