Leak Saver Direct Inject AC Leak Sealer 3-Pack | AC Stop Leak for Most HVAC Systems Up to 5 Tons | Works with All Systems & AC Refrigerants | Made in The USA

If I could give another star I would. I have a mini split system at my pool house. Every year, I’d have to recharge it because there was a slow leak and I kind of knew where it was up in the attic, but I always dreaded to go up there because it was in a tight spot where the connection was. I thought what the heck let’s try this stuff. It’s been almost 2 years and I have not had to put another charge on the system and it is working great. Now I just bought another tube for my house because it has a slow leak somewhere too and needs a little charge and it is an older system so I will shoot that in this week.

IT WORKED VERY SMALL LEAK your leak has to hold vacuum for a short time 15 minutes or so it saved my 4000 dollar refrigerator from the scrap heap it was 10 years old. You need to have a working knowledge of ac systems it’s not a beginners DIY FIX

The best stop leak product available anywhere! My heat pump had a Freon leak and I tried “Leak Saver” leak sealer and it really worked. The applicator tube connected easily to my gauge set and the Ease of installation was very noteworthy. The Valve for the money stands above everything else. The money this leak sealer saved me is unpresidential as it would have been hundreds and hundreds of dollars for an A/C technician to repair my heat pump. I ordered another package just to have on hand for future repairs on automotive or residential unitsYou better get this now!!!!

It definitely slows a leak down a loy. I've used it 4 times so far and it definitely slowed the leak. I am finally going to get a new AC. It did make my ac not lose all the freon as fast as it was.

I have a small and slow coolant leak in our wine frig. The system is small (1.8 oz of 134a) and I hoped that this would solve the problem. I recharged the system and used the product, but the leak persisted and the frig lost temperature again over the same period of time (about 3 days). I bought and tried a second application and still no success. After investing about $100 for the injector and the two treatments, I really hoped this would be a cost-effective fix. Time to research some other products in hope to avoid replacing the frig.

I must admit I was very skeptical about the possibility of this working. In the spring, my air conditioning completely lost all of the gas over winter. I pulled the vacuum re-serviced the unit and then added this stop leak. I ran it for about eight hours and as it was spring, the temperature cooled off and I was not able to run it again for a couple of weeks. Here we are now at least two months later and it is still holding charge and working as it should. Again, I am very happy and very surprised for it to work this well.

I HAD A LEAKING EVAPORATOR COIL I COULD HEAR IT HISSING, Installed leak stop and it worked. I had to recharge every 4 days before. I do have a new coil on order

COMPRESSOR FAILURE!!! DO NOT USE!!!!!!!!!!! They do not stand behind this product although they will give you back your money while leaving you with a $3,000 bill to repair your A/C.
