ZeroR® AC Refrigerant | R134a Replacement | 3 Cans for AC Recharging

The price was right and the quality was even better. This product exceeded my expectations and this company does a wonderful job. I mean it's pretty simple product so it's not like there's a lot of complications and moving parts. It's coolant for the AC for my car. I found this product to be exactly as advertised and the price is better than I can find locally.

it's not 134a, it's some other compatible gas that uses different pressures/weights but it works. my old chevy suburban is running ice cold now. when i was pressing the gas at 2000 rpm temps went into the low 30s and idling went up to the low-mid 50s. the outside temperature is 102 right now where i live for reference. it does seem to work.

I bought the three cans and hooked the first one up toy charging hose and for some reason it won't take the Freon from the van so I went to unhook it and the top isn't like the normal cans where you can take the can off the charging hose, because it has a valve on top these cans once you screw the van onto the hose you punch a hole in the top of the can to get the Freon out of but you can not remove the hose because the Freon will leak out no valve to stop the Freon from escaping from the can. So I'm stuck with a can of freon on my hose and to free the hose up.from the can all the Freon will leak out. I even went to the auto parts store and borrowed their hose to hook another can up to thinking my hose is clogged or something,but nope the same thing happened,no Freon into the AC system,just another can stuck onto the auto parts store hose. I don't believe these can are pressured , because if they were they would have a value on top so you can remove the hose if your system is unable to take the whole can. So do not buy this stuff I've waisted $30 on these cans so I bought more from the auto parts store and tomorrow I'll see if these can work,plus the ones from the auto parts store they have a value on top so I know I can remove the hose when done. So now I'm going to waisted a whole can of this stuff just so I can use my charging hose.

Works fantastic. This is my 3rd order. Used on several vehicles. 1can usually does the job. One truck I charged took 2, but A/C hadn't been used for 8 years.

It worked as it should. Found sensor loose, put freon in and have cold air now

This is a REPLACEMENT for R-134a refrigerant, not the actual R-134a.As the government is phasing out R-134a starting 2015.Do not mix it with R-134a refrigerant in your system, use it in an empty system.One can is 6 oz, but it's equivalent to 16 oz of R-134a.Can has puncture style opening, you must use the whole can once opened.

Very great product worked very well getting my ac working again.

Really need at least 16 Oz can. Kind of hassle, 6 Oz cans.
