Anybody have any thoughts about the use of air conditioning sealants that you put in prior to freon, coolant, R 134 or whatever it is called. I don’t want to spend alot of money, but don’t want to use this if it’s not a good idea, and appreciate your thoughts! ---

If would be best if you had the leak correctly repaired. The sealant might help, but it might also cause problems. I wouldn’t use it unless you have decided to otherwise go without air conditioning. (Once you put it in, it will make it harder to get the system repaired correctly.) ---

Usually, these “sealants” do NOTHING, good or bad…
