Review: Did the job - 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.

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.

### ⭐⭐⭐⭐⭐ Works 100%. Worth trying no this product rather keep spending on Freon.
*by C***K on 23 April 2026*

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.
