Air conditioning problem with recirculation

Hi everyone, this is my issue. So I noticed my A/C was not blowing as cold as it once used to. Like most folks I went and picked up a bottle of AC Pro to recharge the AC. Followed all the instructions per the bottle and it read “low” so I attempted to recharge it over and over again. I think I used about half the can. The AC blew nice and cold and left it running for about 30 mind while I was cleaning the interior. I noticed the fans kick on and then shut off about 2-3 seconds and cycle back on. AC blows hot air and switch the outside air on and switches back to circulate air and will do that repeatedly after a couple seconds.
