I would put half a can of R134 and see if AC cools down. If AC blows warm again in a week, then you have a leak. You only need to deplete the system and vacuum if there is a leak and you need to repair the leak. It is not a good idea to merely release the R134 to the atmosphere. If you have not charged the AC system in 4-5 years, then you are probably a little low on R134 and that is quite normal. You can purchase a can of R134 anywhere without a license but not for R12.
