Review: It definitely WORKS ! - There's not much more I can say about a product that truly works. I replaced my outdoor compressor with R407C, a direct replacement for old R22 system. The coil was in the attic and almost impossible to reach comfortably. It is 25 + years old. This year, I was losing pressure, so I gave this a try. BOOM ! leak stopped immediately. I added more gas and at 90 degrees out, I'm pushing 68 indoors. Contrary to HVAC guys, this product works and at $37 a squirt, any other conversation is used car talk ! And so simple to do, I bought 2 more for other systems I have. TRY THIS FIRST, SAVE THE BS
Review: Fixed my HVAC leak on a 12 year old 5 ton unit! - First off, I very seldom do reviews of a product, but this inexpensive product saved me a lot of $. I got tired of getting ripped off by the local AC companies in my area, so I watched several YouTube videos on HVAC repair and decided to give this shot. I had a small leak in my 12 year old system and the HVAC guy told me that I needed a new 5 ton unit due to its age. Long story short, I tried this product and it fixed my leak. It is well worth the cost. Great product!

## Features

- THE EASIEST INJECTION METHOD: No more fussing with messy syringes, hoses, or pressurized cans. The Leak Saver 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.
- MORE THAN 3 MILLION UNITS SOLD SINCE 2015: The Leak Saver can permanently seal small refrigerant leaks where the complete refrigerant charge is not lost within 72 hours. It’s similar to how blood in your body reacts to a cut. 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.
- WITH ADDED UV DYE FOR FINDING LARGE LEAKS: Seal it or find it! If you have a leak that is simply too large for leak sealants to seal, the added UV Dye will light up brightly at the leak site when using a UV flashlight.
- COMPATIBLE WITH ALL SYSTEMS AND REFRIGERANTS: : The Leak Saver UV is compatible with all systems, refrigerants (except ammonia), and oils. It is great for central air conditioners, car and 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.
- YOUR SATISFACTION IS OUR PRIORITY: We stand behind the effectiveness 100%. If for any reason you are not satisfied with your product, please contact us and we will make it right.

### ⭐⭐⭐⭐⭐ Works great so far!
*by P***Y on April 28, 2026*

I bought this exactly one year ago. I put it in myself. It's quite simple to do using the CO2 powered gun I bought separately. 2 years prior to getting this every time I turned on the AC for the summer I had to add about 3 pounds of 410. This year I turned it on and low and behold I had cold air! I'm not saying its perfect and wont need ANY 410 this year but it's working so far! I know some "Pros" say not to use this kind of thing but I learned of this stuff from the other Pro sites on YT that recommended it. It's well worth a few $$ to try it.
