Leak Saver Direct Inject AC Leak Sealer Small System | AC Stop Leak for Most HVAC Systems Up to 1 Ton | Works with All Systems & AC Refrigerants | Made in The USA

Used this on a mini-split system and it sealed the leak perfectly. Super easy to inject and compatible with all refrigerants. No issues since—definitely saved me from a costly repair!

Product delivery was on time and is of excellent quality. The item is new and has been delivered in a timely manner. The appearance is very good and of great value.

My kegerator lost all its Freon. The leak saver was easy to use and two weeks later my unit continues to work great after holding a recharge. I would certainly recommend trying the leak saver before having an expensive repair done. Seems to have worked for me!!

Had a leak in my AC system. After getting it refilled with coolant, I added one shot of this stuff and so far so good. It's only been about a month but the AC is working great and is Ice Cold. Hopefully it lasts a lot longer and stays working this good. Will update if this doesn't seal my minor leak...

Don't waster your time or money. It doesn't work. I had a tinny leak (took almost 3 months to drop less than half the freon charge. Product did absolutely nothing. See before and after pictures. The "after" picture is after cleaning to attempt sealing with 2 part epoxy. Seller offers warranty but doesn't respond.

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.

Customer service was really great. However the person said yes you can use it when it is set to heat, the instructions say you can not. Unit must be set to cool and you must run it for an hour, which didn't sound awesome when it was 40 outside! We'll be using these on different houses to act to protect the system

Excellent company and product. I found my self not installing the product incorrectly and called customer service. The Miss my call and surprised they call me back. They replaced the product for free. 5 star.
