Car Air Conditioner, Certified A/C Pro Refrigerant Leak Stop Kit for R134A Car Air Conditioners, 3 Oz Each

I followed directions and so far my 1998 c5 is holding Freon and blowing ice cold. I will do a follow up in a few days.Well it’s been 7 days and still holding charge.I will do a follow up in a couple of weeks.

This product actually works as a short term fix. But only as a short term fix, such as for one last hot season where you need AC before you are planning on getting rid of the car. It came with a detachable hose that made it easy to dispense. A qualified mechanic will tell you, however, that using a solution like this will contaminate the system over the long term, so the application for this product is narrow. But within that narrow parameter, it works.

Didnt work to good on freezer

The a/c in my pickup started leaking freon, and after charging it, it would hold for a little over 2 weeks then no more a/c. I was really dreading taking it to a shop to find the leak because first it will cost to find the leak, then to fix the leak, the to recharge. That would really tear a hole in my bank account that I cannot afford.I seen this stuff and figured the worst that can happen is wasting the money. That was over 2 months ago, and the a/c in my pickup STILL works great. Super Seal saved me a LOT of money.***UPDATE***Its been a year later (almost to the day), and the a/c in my pickup STILL works great. I have recommended this to MANY people, and will continue to do so.

I was skeptical about buying this leak stopper because my mechanic told me the leak on my Evaporator Coil can not be stopped or sealed by any leak stopper on the market but I took a chance on this stopper because of some customer reviews I read and I charged it into my 2nd Gen Prius and it worked. My AC is blowing cold air now like before and four weeks have gone by and my AC is still working good. I want to take this opportunity to thank the feedbacks I received from some customers whose review really helped me to decide to purchase this product. Thank all of you! I hope this product stopped the leak for me permanently.

Was recommended by my mechanic who i trust. Didn't work though, hole must be too big

I tried this on a recommendation from tic toc (please don’t judge me!). The guy was right, this sealed up a slow leak and the system has held a charge for months now. Very easy to use as well. Highly recommended

So I own a 1988 Chrysler LeBaron coup, otherwise known as my baby. Last fall the AC quit working, took it to my guy who has worked on her for thirty years and he said the evaporator has a leak in it and needs to be replaced. This requires removing most of the interior. I didn't like the sound of that but said let's wait until spring to do it since I put her away for the winter. When spring arrived, I was having second thoughts about replacing it, not the cost but tearing her apart. I saw this on Amazon and thought what do I have to lose. I used this on Memorial Day weekend and its now the end of July and she is still blowing out nice cold air. Don't know how long it will last but for now I couldn't be happier.
