Review: The product made the promise! Highly ecommended.
Review: 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.

## Questions & Answers

**Q: Will this work with my system?**
A: The Leak Saver works with all air conditioner and refrigeration systems. It is compatible with all refrigerants (except ammonia) and is compatible with all oils.

**Q: How does the Leak Saver work?**
A: After injection, The Leak Saver sealant circulates throughout the system with the refrigerant. If there is a small leak, the sealant reacts with the moisture and oxygen at the leak site to form a permanent "scab-like" seal.

**Q: What do I need to install the Leak Saver?**
A: To inject the Leak Saver, you will need either a basic set of manifold gauges or our Leak Shot injector. When using it with automotive systems, you will need a 134a to 1/4” adapter. Ductless mini-split systems may require a 5/16” to 1/4” adapter.

**Q: What size leak will the Leak Saver seal?**
A: The Leak Saver is able to seal small refrigerant leaks where the complete charge is not lost within 7 days. If this is not possible, your leak is too large to be repaired with Leak Saver.

**Q: What do I do if it doesn’t work?**
A: We stand behind the effectiveness. If you are not completely satisfied, please reach out to us directly and we will make it right. With more than 4 million units of this formula sold since 2015, we have a strong track record of effectiveness.
