That was the price I was quoted last year for a new AC system after an HVAC tech determined I had a crack in my evaporator coil in my existing 10 year old system that was letting the coolant slowly leak out. Said it couldn't be repaired and that I should just drop $15,000 and buy a whole new system. Instead I found this fix on Amazon and gave it shot. After using it with the seperate injector gun I bought some replacement refrigerant online plus a manifold and topped off my system myself after watching a youtube video. Since that moment 11 months ago my HVAC system has worked perfectly even through the brutal summer.

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.

Works as advertised. Not sure if it will require another treatment down the road. That’s why I bought the pack.

My home's A/C had a leak that I eventually found in the evaporator. Over a two day period the system would lose about 4 pounds of freon. I added the leak saver then recharged the system. This was 2 weeks ago and the leak appears to be sealed. I have an electronic freon detector that originally detected the leak location. After adding leak seal the detector did not detect a leak even on the highest sensitivity setting.
