Where can you go to exchange Canadian coins for U.S. coins?

I found some Canadian coins while I was cleaning and I would like to know where I can go to get them exchanged into U.S. coins.
Are you able to do this at the airport? If so where? I heard that there are machines at the airport that will convert coins for you but I don’t know where those are located at.
I have also heard that banks only convert bills and not cents.
