1.5 years and it loses all of its refrigerant!? Holy crap dude! That needs a real repair in my opinion, 1 lb a year is the heaviest I've ever seen these fix, but at least it can slow the leak down and the uv will show where the leak is
Worked quite effortlessly for me. So far, my unit still works at full charge. I do not believe this is going to be a permanent fix and probably it will only help with very slow leaks, but it´s worth a try before investing the money needed to replace an evaporator o who know what other stuff where the leak might be at
If you used it and did not work, that is a disappointment. Maybe your leak was more severe. Mine was a slow leak and so far the unit has not lost charge. We´ll see over the next few moths. As of today, July 22nd is still working at full charge... we´ll see...
