      David Fernandez You can rent an AC vacuum pump at autozone or Oriely’s you hook it up to the upper AC port and turn it on let it run up to an hour and it gets all of the old Freon and moisture out. That way when you put new Freon the system will be empty and you can put exactly the amount of oz of Freon in your car that it calls for So your not guessing how much is in the system..

      NO JOKE! I think ATP AT-205 Additive would be my first choice. However, you would have to have a rig to introduce it to the A/C system. Thoughts Scotty???

      My vehicle's air conditioning system is take the doors off and the windows. At night, take off the top and lower the windshield as well. It was a air conditioning developed in 1941. It works great, except when it rains.

            Hey man! if you have a leak, you can leave the system on a vacuum for 10 years and it will not pull a sufficient vacuum to do anything. you have to fix the leak FIRST!

            • checkinout6000
              checkinout6000  1 weeks back

              @TeraVolt you are the one that used the term 'magic'. I don't think any of the engineers involved in designing these systems will approve the use of such a term. I also encourage you to revisit the term 'wear' as I can assure that the engineers will not get behind you on this either. Webster has an amazing product that I suggest you use. Modern refrigerant oils are corrosive by nature. Rubber does not last forever and is why you have to buy new tires but they actually 'wear' since there is friction involved. They also do not 'magically' seal themselves without introducing some other type of sealant which is not magic. Back to your original claim; the idea that getting your vacuum gauge to drop below 29 inches is a sufficient vacuum is completely false. I know there are a lot of technicians out there that believe this fallacy. Many think you can clear a system using pressure. It is also a very good idea to zero the gauge prior to evacuation. If you do not reach a full 29.85 inch vacuum, you are pulling non-condensibles into the system and creating a plethora of new problems and failures. Refrigeration is a science based on thermodynamics and not magic or witchery. Wear involves friction. Go and consult a good dictionary and replace your tubing seals before trying to pull a vacuum.

              @checkinout6000 Not running the system regularly ends up drying them and shrinking them up. No oil circulation, no lubrication. That's how they wear. Matter of fact. I've seen a lot of old o-rings pulled out from neglected AC systems and most of them look pretty dry. Frankly, i fail to understand how Houdini is involved in all of this.

            • checkinout6000
              checkinout6000  1 weeks back

              @TeraVolt Oh yes, the magic O rings that they are using now. Just how do they wear when they are not moving? Don't tell me, you went to the Houdini school of refrigeration.

            • TeraVolt
              TeraVolt  1 weeks back

              Not every time. There are leaks which magically close under vacuum, and then resume leaking when pressurized. Usually worn o-rings do this. That's why ideally you should both test it under pressure and under vacuum...

                When you removed the A/C service hose after the vacuum, you sucked air in the system, since the service port valve only close under pressure, not vacuum

                  Service port valve has a spring which lets it close when there's no pressure. At least on my car (which has Santech MT0059 valve cores basically).

                      Scotty I got a 2016 Nissan Altima SV with 59k miles. I wish I would of started watching your videos back in 2017. I should of picked a toyota or Acura lol. Anyway my ac is messed up. Only blows cold at nigh or went it rains. Two different mechanics told me it’s the AC compressor and it’s going to cost around $500 to fix. Any suggestions on a cheaper place to buy a reliable compressor or just swallow the cost and get it fixed at Nissan. I’m in the northside of Houston. Thanks !

                            @rhcev6 Scotty mentioned this stop leak should work on any Small AC leak but it's the best if you can replace broken part in the first place.

                            @Ja Sam thx! the leak sealee Scotty talks about... Is that good for the compressor seal from lack of use OR is that seal able to be replaced?

                            Yes you can.
                            When you use AC, compressor circulate freon and Oil inside your AC system thus lubricating components.
                            Oil also helps rubber seals inside stay playable and not dry. So if you don't use AC for long time rubber seals gets dry from lack of lubrication and they get brittle and they crack.
                            When you finally do start using your AC again, it starts leaking freon around those rubber seals. Use your AC from time to time to get your system working properly.

                              If you're going to that time & trouble, replace the evaporator, orifice, dryer, & lubricated* o-rings, plus charge, & be done with it!

                                                            Super seal absolutely does work! As a professional auto tech - I've used every a/c sealer on the market and without question - super seal is the only product that I've ever had great success with. I once went to a seminar in which there was a complete automotive a/c system mounted on a table top for demonstration purposes, the compressor was turned by an electric motor. As the system was ran and operating normally - a guy drilled several 1/8 inch holes in various locations at the evaporator and condenser. Within seconds the system was depleted and stopped working(ozone layer be dammed I guess!) The man then added a can of super seal followed by a recharge of the system. To my amazement you could easily see the super seal material oozing from all the drilled holes then form a plug which stopped the leaks entirely. The system was topped back off and then allowed to operate for another 30 minutes. The man then scanned all the sealed holes with a leak detector both while the system was running then shut off. No leaks of any kind were detected at all! I was sold on this product from that day on and have been using it successfully for budget type repairs ever since! It truly is an amazing product!
