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

Easy to use , straight forward application

I've got a slow leak somewhere on my 16 year old r410a 3ton Lennox Hvac - losing about 2lb of refrigerant over 8 months or so.Decided to try this leak saver as a last ditch hail Mary before biting the bullet and replacing the system. Used the charge in with refrigerant method - tube was clear and it was in in a couple of seconds, very simple. Left the tube attached while I topped up the rest of the refrigerant to the correct level. System is currently running great again, heating and cooling as it should. It's only been 3 weeks and given the leak is very slow before it becomes noticeable, it might be a while before I can tell if this has worked or not. I have shined my UV light round the usual suspect leak spots....have not seen any dye. Will check back in in a few months to see how it's doing, fingers crossed at this point!

i have a feon system from 2000...the hvac guys wouldnt fix it and only wanted to sell me a new ac unit for my house- 12k yeah ok surei got this stuff, 2lbs of feon, and boom - fixed itthis summer 90-100 f and higher... my house chillin at 70f all summergreat product this is and easy to install in system

Not readily able to use on R-134A systems.The connectors do NOT fit 134A !!

Very easy to install. Put it on low side and push in with some refrigerant. It went in without any problem.
