Could be alot of things. Go outside and check and see if the compressor clutch engages when you turn the ac on with the car running. If it doesnt, then unplug the connector for the ac pressure sensor. With the car running, and AC ON, Use a small piece of wire, and link the two wires of the wire harness connector together. Did the compressor turn on? If it did, then your low on freon, or have a faulty sensor. If it didnt, then your logicon, or some other electrical issue is at fault.

Should I just take it to a shop that does AC stuff and check it or is there something I can check to verify?

wow so angry...you and Icemark both answered my question. You have 6 posts he has over 20,000 and is well regarded here. Not that you dont know what youre talking about, and I certainly can check what you told me. I was looking for more than one opinion since this board is full of people who have some pretty crazy ideas about rotaries.

Back off man I read your post and will do the wire check. I was simply answering Icemarks post as to where to get it filled. Go drink a cup of coffee or something
