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

Ok please read my back story. I'm a handy guy, I can fix almost anything. There are only two mechanical things I am not experienced in. 1) Automotive transmissions and...2) Home HVAC. I know the basic principle of home HVAC but never had the tools to work on it or guidance to teach me. Anyway, I have a house on the water, ocean access water in the Ft Lauderdale area. The AC on my home is a 20 year old 4 ton Rheem unit, R22 and exposed to salty humid air. It cools fantastic but over the years there have been a few leaks on the U tubes on the condenser coil (the outside unit, high side) and I had a long time AC guy that has welded the leaks and got me going. This last time a couple weeks ago the AC guy basically told me "my AC is shot I need an entire new system and he can't and won't attempt another repair, the cost of a new system is $8,000". Well I don't have $8,000 so he basically told me "good luck" and left. That's when I started researching these leak stop shots. My long time AC guy said my R22 system was empty and I believed him because the AC was cooling one day, then the next day freezing up then the next day barely blowing cold, the next day the low pressure switch was shutting the compressor down. Ok so I did my research. I bought two of these Leak Saver injections and a 15 pound can of R22....which was incredibly expensive, but cheaper than a new system. So i hooked the can of R22 to the leak savers and shot them in followed by a nice charge of R22. It's been about 2 weeks and the AC has never worked better! Also my AC guy said my system was empty, it's a 4 ton and holds about 11 pounds of R22 and it took 7 pounds to fill so I have plenty of extra 22 and an extra leak saver for the future just in case. People, this Leak Saver WORKS! My 4 ton R22 split system was leaking out at a rate that would have left it empty in a week, it's been 2 weeks and it's blowing cold! Plus I am putting the gauges on every few days to monitor pressure, it is stable! I am amazed this Leak Saver worked. Blown away actually. I gave this stuff about a 5% chance of working on a 4 ton high side leak. Give this a shot before spending thousands. Your biggest expense will be buying R22 but it is available online.

Easy to use & is working well. My AC unit was installed back in 2001 so it was beginning to leak refrigerant and freeze up constantly. Fortunately my neighbor told me about this product and not only has it saved my family from the Texas heat but it also saved me money.

Bought to fix a Freon leak in the lines in my freezer. Worked like a charm. Be careful as it may not work on larger leaks. Make sure to read instructions carefully. If you fill your line up with Freon and you have a slow small leak this product should work for you. What’s great about this is the excess stays in the line and if you spring a new leak as soon as the air hits it what’s left in the line will seal the new leak as well. Not sure how long it will last but so far it’s been about 2-1\2 months since I used it and I have not had an issue since. My freezer is freezing properly with no issues.

I love this product! Instead of an expensive unit replacement for a refrigerant leak, Leak Stop saved the day. Even after a week of scorching 90-degree weather, my AC is still working perfectly. Applying it was a breeze, especially with the convenient CO2 applicator. Highly recommend for saving money and hassle-free maintenance!

This is a great product. I had my 2.5 ton unit serviced and topped off, about 2 weeks later the unit was not cooling and low on Freon. I read the reviews and watched videos about this product and decided to give it a try. I topped off my unit again and added the Leaker Saver to my system. It really works, my system has been cooling fine for weeks now without any issues. No drop in pressure and its cooling great again. If you have a small to moderate leak, definitely give this a try.

Easy to add if your adding freon to the system. I use it when I can't find the leak. It has worked for me very well over the years. I prefer it over the injection models or the cans that sometimes don't seem to suck out the product. Takes 5 mins to use and is fairly cheap. Highly recommend.

Update : After posting my review the seller reach out and offered a full refund. They did not ask me to change my review, but I think it’s only fair that I give them credit since they were not obligated to refund any of my purchase price. The only thing they asked was that I give them another chance in the future, which I may do. Product didn’t work in my case, I followed the mfg. instructions but this did not fix the leak in my mini-split A/C system. Not sure if it’s just this specific product or all product like this one in general, but it was a total waste of time and money. Be aware, there are no refunds on consumable products, so you are going to have to accept the risk if you decide to use this product.

I use this product quite often in the field of appliance repair.

The product made the promise! Highly ecommended.

My window AC has a micro leak... I can say it is very minimal leak, it slowly loses pressure for about 3 months but still not totally empty and can still cool to a minimal level. From 65psi, it goes to about 30psi in ~2 months and about 20 psi in 3-6 months. It will not empty out totally and will just stay at about 20psi. So, let us see how this works out for me. After 1 month i will check the pressure again, I know i will lose a little pressure every time I measured with my manifold and will consider this too. UPDATE: After about 20days of usage, the pressure dropped again at 20psi. meaning it was not able to hold the pressure and seal the leak. anyway i enjoyed using it and hope it can work for others

Le produit fonctionne très bien presque toujours…

It got to me almost empty. It was leaking inside the package. Couldn’t use it.

Easy to use and in works. Has been in system for nearly a month and looking good.
