Review: Saved me $15k - 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 desertcart 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.
Review: Easy to use product - Works as advertised. Not sure if it will require another treatment down the road. That’s why I bought the pack.

## Features

- 3-IN-1 SEALANT + MOISTURE REMOVER + UV DYE – Our proven leak sealant now includes moisture remover and UV dye for the complete system treatment! Now, you can seal your leak, remove system moisture, or find large leaks with the UV Dye...all in one easy to install package!
- STOP LEAKS PERMANENTLY - The Leak Saver can permanently seal refrigerant leaks where the complete refrigerant charge is not lost within 7 days. When a leak occurs, the Leak Saver reacts with the air and moisture at the leak site to permanently seal the leak. When used for preventative maintenance, the active ingredient circulates safely in the system to seal future leaks
- WORKS WITH ALL SYSTEMS & REFRIGERANTS INCLUDING CARS - Our product is compatible with all systems, refrigerants (except ammonia), car refrigerants, and oils. It is great for central air conditioners, automotive air conditioners, refrigerators, ductless mini-splits, heat pumps, geothermal heat pumps, commercial refrigeration systems, micro channel coils and more. It also works with all refrigerants including R410A Freon, R22 and replacements, R134A , r1234yf, R404A, R290, R600a, and more
- STRAIGHTFORWARD INSTALLATION - No more fussing with messy syringes, hoses, or pressurized cans. The Leak Saver HVAC sealant injects directly and easily into the system with a basic manifold gauge set or even easier with our Leak Shot Injection Kits. NOTE: for automotive systems, you will still need the standard 134A to 1/4” charging adapter. Mini-splits may require a 5/16” to 1/4” charging adapter. You can see our straightforward installation videos below
- SAFE FOR ALL TOOLS AND PARTS - Our HVAC leak sealer is safe for all manifold gauges, hoses, expansion valves (TXVs, TEVs, capillary tubes, etc), Schrader valves, and anything needed to service your system. Adapter required for mini splits (5/16" to 1/4") and automotive systems ( 134A to 1/4")
- THE MOST TRUSTED - The numbers don’t lie! With more than 4,000,000 units sold of our air conditioner leak sealer formula since 2015, we are the most trusted leak sealant among HVAC professionals. Proudly made in the USA. We stand 100% behind the quality of our products. If for any reason you are not satisfied with your order, reach out to us and we will make it right.

### ⭐⭐⭐⭐⭐ Worked like a charm
*by M***K on July 20, 2026*

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.
