I've used it on 2 light commercial 5 ton AC units with both R22 and R410a refrigerants. Both units had slow leaks that couldn't be located easily; so not wanting to pay for the repair costs at this time, I opted to try Leak Freeze. The Leak Freeze was very easy to add to the systems and have stopped the leaks to this point in time. Normally I would have been thinking about having my HVAC guys refill the systems for the second time by now!!!

This is great stuff. I had a very bad leak on 22 year old heat pump. It was leaking the whole charge over a weeks time. So I thought I have nothing to lose. Pulled a vacuum on unit installed nu 22 do to cost of new r 22 Charged up unit and it is still working several months later. No leaks that a can tell. The leak freeze was very good at fixing my leak. Which was a very bad one. Very happy with this stuff. Well worh giving a try if you have a leak.

I have a 22 year old R22 A/C unit for my home. The unit has never required freon until this year. I used Magic Frost and added freon. The unit is still leaking (slightly), but it did last me through the summer. I plan to add another shot of Magic Frost and freon next summer and see if this old unit will last another year. Granted the leak may be small, but my goal was simply to make the unit last another year of summer.

So far, so good. I don't know if the repair is permanent yet, It's been 2 weeks but that's twice as long as the last charge without it. Local HVAC quoted me $1500 to replace the leaking air handler. I also liked that it was immersed in oil for the compressor. I used a caulking gun to inject.
