This product worked for me. Sealed a leaking 25,000 BTU AC unit, and it's working fine now. Product was also close to half the price the technician quoted me for the same product, and it came with the installation hose too. I would recommend it.

Followed instructions and refilled freon to proper amount. Then added sealer..within 3 months same situation..freon was down and had to add more freon. Main problem is a bad sweated inlet pipe which this should have fixed.. Should have saved money and had hvac repairman fix in the first place..

Two days after installing this product my compressor locked up. The complete unit then had to be replaced. The smell of this product is very questionably strong. When it came in contact with the R22 from the low side, the can got very hot due to a chemical reaction. With over 40 years A/C experience I feel imberessed having been caught up in this gimmic.

Used on house HVAC, My refrigerant line was freezing/sweating and my ac unit would turn off when that happened. Checked everything to make sure I didn't have any air restrictions and determined I was low on r23 refrigerant. Charged the system and Installed this can of stop leak. I followed the instructions on the can and my system has been cooling properly for a week now! Not sure how long it will last me but definitely prolonged me from having to purchase a new ac unit

Its easy to use. There is no real way to tell if it works or not until the system runs for 6 months or so to see if it leaks or not. It is only usable for very small leaks.
