Our air conditioning system was not keeping up with the heat and we were spending a fortune on refilling the refrigerant every friggin' week. My husband purchased this on a whim, and, miraculously, problem solved. Our air conditioning actually gets too cold now. Recently, my son had an issue with his air conditioning, so I sent him this leak sealer to see if it would help. Sure enough, his air conditioning stands up to the summer heat with no problem, whereas previously, it was barely able to cool the house down. This is great stuff!!!

I had tried other Freon leak stop products, none of them sealed the leak, decided to try this leak seal product. Seems to be working and it’s been working for 3 months now.

The product very easy to use and since the tube is clear, you can easily tell if the solution has entered the system. Guess, will know by next year if it works as it is advertised.

To all the AC techs that always advise against sealers here is a case for you and I also say, what do they have to lose? I had a friend that had an AC unit with a leak bad enough where it would pretty much leak out its contents within a month. Against my recommendations we filled it back up and within a little more than a week it was out again. I figured I'd suggest trying a leak sealer as replacing the unit was not an option financially for her so what did she have to lose. We added this sealant and I warned her about the possible consequences. We added more refrigerant and this time it slowed the leak down back to a month. So I added "leak saver " brand next and between the 2 of them there have been no more issues and knock on wood the AC unit is still going strong in Las Vegas heat with no compressor issues etc. And yes, we looked to locate leak initially. Her condenser had many small leaks at the bottom coil due to water corrosion and who knows if she had any in her evap also. So repairs were not even worth attempting. Whether or not aluminum coils matter to the leak sealers I do not know but this has aluminum.
