I had used the AC Pro a couple of years ago with the 20 oz can, so I already had the fill line. This is supposed to have a formula to stop minor leaks, we’ll see. I have multiple vehicles that use 134A, so it is nice to have around. One vehicle was putting out 62 degree air at the vent, 4 oz, dropped it to 46 degrees, cooling the car much sooner in hot weather. Others sell for less than the $13 I paid for 12 oz, but going to the mechanic would have been around $50. Doing it myself took 10 minutes. Good directions on each can, even first time users could manage this.

Mechanic quoted me up to $2000 to repair a leak in my rear ac lines buried in the ceiling of my suburban, so I tried this instead. One can of this sealant, one can of the dye variant, and three cans of just coolant fixed the leak flawlessly, and recharged the coolant (yes, 5 full cans!!! in my thirsty truck to activate the low pressure cutoff!), and it hasn’t leaked AT ALL in two months of use. Sealed awesome!The “arctic freeze” and dye tracer variants from this same company work great – very visible dye, and my ac had never been this cold even when freshly charged by standard 134a, so their “booster” is doing something good. Bravo!

try two more times! That’s what I did after trying to locate the leak either with dye and refrigerant leak detector – tried to go at it methodically. In the end, one can sealed it for a few hours, second can for a few days, and the third one for a few weeks now.

Chill out dude! My 2011 F150 had a A/C unit blowing stinky warm air…I took it to a A/C shop and they wanted 1650$ to replace the evaporator coil..I told them I’d think about it..Translation..Go to hell!…Anyway, I discovered the vent was filled with small leaves and was clogged up. I ended up vacuuming the leaves out and using an air compressor to get the coils clean again. Also, I ended up cutting a small window into the plenum box to look at the evaporator coil and then sprayed it with water to clean it off..It also turned out the shop took all the Freon out of the unit..Anyway, I refilled the Freon after cleaning the coils and leaves out..And low & behold, the A/C unit has been working fine for the last 3000 miles or so..maybe 2 months .

Used this product to recharge and seal my RV air conditioner. Air conditioner has not been working since I bought the RV 3 years ago. So far so good: its been 2 months and it still cools.

Love it. I’ve never added Freon to my AC system but I was told I had a hose leak which would cost hundreds, that I didn’t have. Learned through the instructions and YouTube. Did it this morning and it worked! AC blows cold. Time will tell if it fixed the leak but there is plenty left in the bottle to redo it if necessary. It will either seal it or at least buy me time to save for repairs. I would have been out of work because I use my car for work without this and it’s getting hot in Phoenix so this was a lifesaver!

Attempted to recharge the car’s a/c system with this product, but the can wouldn’t empty out the contents after more than three different attempts each lasting about an hour. I figured something might be wrong with the car or with the can, so I before I tried investigating the a/c system, I bought another brand of refrigerant and that other can emptied quickly within 5 minutes my system was fully charged and blowing cold air. I determined the A/C Pro Refrigerant can I bought on here must have been faulty or something so that’s the reason for two stars.

Works Great, just wish it was a little bigger. like 16 or 24oz or bigger.
