Yes we all know it’s not correct because we aren’t paying a shop $300 to do it but having cold air for $30? Can’t complain about that. I’m an engineer, licensed A&P mechanic and airline pilot and except for not pulling the vacuum for long enough I can’t see how this method differs from the job the pros do. This isn’t rocket science, all we are doing is pushing fluid thru a small hole which causes it to cool as it expands in the evaporator and magic, we have cool air! You could fill it with any fluid that won’t freeze and it would work, maybe not as efficiently. If you have been driving around without AC because of the high cost to have it serviced then maybe this method is for you.
