ZeroR® + Honeywell R1234YF Refrigerant Recharge Kit | 24" HD Can Tap Gauge | 8oz R1234YF (4 Cans)

A/C was blowing hot . Shop wanted to do $800 service. Got this kit in 2 days. Added the gas as directed. A/C now blowing cold last 30 days now.

Only needed one can……..bought the four in case I had a leak. Now I have three cans for the future if I or someone else needs them.The main thing to do is verify the refrigerant before charging your system.

Although seemingly expensive this product was among the lower prices options. However, one must be extremely careful when connection the supply hose to the gas canister. There are no directions and the thread is a REVERSE THREAD. Meaning that one must screw it onto the hose coupling counterclockwise, the opposite of normal items we screw in place every day. I only learned about this after failing to connect at all and looking at the customer comments on Amazon. ONE user mentioned this reverse thread. Again, no where on the can or the packaging does this information appear. It will NOT thread on clockwise. Also, the shut off valve arrived in the open/extended position. So if not retracted it will immediately enter the gas canister and discharge the 'Freon' fast. While struggling with the aforementioned reverse thread I pushed it in and twice discharged the coolant back at me. Otherwise it seemed effective and easy enough to connect to the "Low" pressure engine valve and improve the vehicle's cooling.

Got for my 2017 BMW. It fit right away with the correct nozzle and the right freon. Way, Way, Cheaper than going to the dealer.

Easy to use

Save your money DO NOT BY - I purchased this for my Acura RDX to recharge AC. I have many years of experience at this but when I used this product it leaked from the connecting knob - whole can got wasted. When I contacted seller they asked me many questions and I supplied all the evidence with photos - NO REFUND - they wanted me to ship the product back at my expense - I read other peoples comment that if I return at my expense seller will refund only portion of the price - SO I WOULD BE AT THE LOSS all over - plus shipping cost - DO NOT BUY - DO NOT BUY

I live in Florida on the east coast and we run our AC all year round, so it gets way more use then most people would in other states. My wife’s 2018 Hyundai Elantra GT turbo air conditioning wasn’t blowing as cold and as the weeks went on it finally started blowing warm air. I thought leak but I recharged it 2 almost 3 weeks ago and it’s still blasting ice cold air like the day we bought it. If it has a leak it must be very tiny but bottom line this kit had my air blowing ice cold in less then ten minutes. Now i did empty the remaining refrigerate out of the system because you don’t want any old product or air in the system. Buy the kit that sucks it out and don’t release it into the air like I did. This new product is environmentally friendly but it’s probably not the correct thing to do.

You don't have to be a mechanic to recharge your AC. I watched a couple Youtube videos first and it was a snap. Be sure you get the correct refrigerant though. When you open the hood of your car, there is a sticker on the under-side of the hood (at least on my car) that tells you what refrigerant you need. MY ONE WARNING ABOUT THIS: Look closely at the hose and pressure gauge. The color scheme on the gauge dial is NOT intuitive, green is not "good". Read the text on the gauge to know where you want the needle to go. Also, the valve on the hose kit way open when I attached the can and I lost some gas before I could get it shut. So just make sure the valve is closed before hooking up.
