Unless of course you're really low on r134a, as I was recently. Then your A/C won't do bupkis when you turn it on. I put 2.5 cans of refrigerant into my system and it's so cold now there's condensation on the outside of the windows. Go down to the local WallyWorld/PepBoys/etc. and get the recharge "kit" that includes the gauge. Hook that up to the low pressure port (closer to the battery) and start the car up and switch the A/C on Max and the fan on high. If the reading is 0 plan on putting in a few cans of refrigerant. If it's in the 25-40 range take it to a pro to get checked out.

Good luck,
