Leak Saver Direct Inject Ultimate 3-in-1 | AC Refrigerant Leak Sealer | with UV Dye & Moisture Remover | for Most HVAC Systems Up to 5 Tons - Professional AC Leak Sealer - AC Stop Leak

Did the job, been 4 months and the AC is still working great after it was added with the freon. Normally the freon would leak out after just a few weeks. This is at our condo in Punta Cana where it’s 26 to 34 Celsius during our winter months there.

This stuff is the best! Easy to use and works great.

my HVAC unit has very tiny leak. I spent two to three times on technician to find what is wrong with HVAC but their Freon sniffers could not do the job as leak was so little that even professional tools didnt helped. After every few years, I spent $ on freon as no one would come to conclusion on why freon is low and where is the leak. Finally I googled and used this product. I followed the instructions. As leak was very small, I waited 11 days. Today I found the leak. The technician was right. He suspected the coil, but his tester could not prove it. And pressure gauge would not drop a psi on test for almost an hour. I was looking for a proof and this product made it clear that coil is to blame. I highly recommend this product as things can not be easier then this for to come to conclusion.

I had "professionals" come look at my central 410A A/C unit. It has a slow leak, frosting every 3-4 months so figured they could find and fix the leak. They charged over $400 to come out and tell me there was a leak. They provided pictures of the inside low side piping as where the leak is and said it would be over $1700 to fix it. That's when I decided to become an A/C repairman. Figured for that price I could buy all the tools and equipment I need to fix it myself. To make a long story short, I found the leak outside on the low side piping (no leaks on the inside). I can replace the copper or try this product that says it stops the leak, takes water out of the refrigeraterant, and injects an infrared die so I can check if it continues leaking. For the price it is a no brainer. The sealer has been in for several weeks but since it was a slow leak, I won't know if it worked, or not for several months. I expect next seasons start-up will determine if it works. Meanwhile they offer a free infrared light (hence this review). Once I get it I'll do another once over on the unit to identify any other leaks I may have missed.
