ZeroR® AC Refrigerant | R134a Replacement | 6 Cans for AC Recharging

This is NOT R134a, incase you didn't notice. R134a is odorless and non-flammable, this is neither. That-said, it smells good and works even better. Had to totally evacuate my system due to a bad o-ring, so I knew I wouldn't be mixing chemicals with just a top-off. One strangeness was, I'm used to seeing high-and-low pressure increase beyond ambient-temperature, if I (intentionally) add more charge than necessary; this never increased beyond ambient no matter how much extra charge I put in... but no complaints.

Great product would recommend this product to others

is your car ac hot or not blowing cold but kinda cold , Well this is what you need , first you need to make sure that your fan is blowing , yes , then make sure your ac compressor is coming on when you turn it on on the dash in your car, you can do this by , car in park, start car, open hood, have someone turn on your ac while you stand outside on the side of the front of the car ,the side that the ac compressor is on , do not put your hands in the belt or fan , your listening for a clicking or change in sounds while someone turns the ac on , if your not sure have them repeat this several times, so if the fan blows,the compressor clicks then you should trying adding this R-134a freon, you will need a hose that hooks to the can and the car ac system,turn the car off, add a small amount of freon gas, STOP , listen for any hissing , if you here this you should stop and find out where the freon gas is going, if you can't stop it from leaking ,STOP you are waisting your money, if no leaking then , add 1 can , run the ac wait , if still not cold add alittle more ,to much is no good, just a little at a time, I advise watching a DIY video first ,you can do this, enjoy

So it’s been in the car now for a week. I’ve had zero issues other than the fact that I had to use more of this product than I would or 134 a. Ice cold AC. You really should have a gauge when you put this in Because I use a whole extra can. Time will tell. But for right now five stars high school AC.. As a sidenote, I did place a vacuum on it, even though the cat says not to.

I read the reviews before I purchased this, and I saw some mixed reviews. I just wanna make this clear. I have 25 years in automotive experience, including HVAC in and out of cars. Having that said, this is not exactly R134a Freon it’s something that is different molecularly But it works very very well. I was shocked. I pumped 2 pounds of this into a 2000 Chevrolet k1500 pickup, I can almost guarantee you that the air conditioning did not work as well when it rolled off the showroom floor then it did when I charged the system with This refrigerant. It does in fact make the high side pressures run lower, which is good to a fault. If you’re not sure about how much to put in your system you need to base it off the pressure readings and add accordingly. After I charged the system up, it dropped it to 54° in the cabin AT IDLE IN THE MIDDLE OF ALABAMA SUMMER. I will definitely purchase this again the next time I need refrigerant.
