Car Aircon Air Con Air Conditioning Top Up Recharge Refill Regas DIY Gas Can

I bought this along with the recommended pressure gauge as my wife's aircon was not working well. The gauge allowed me to see that the pressure was inf act low and that there was not a leak. The hardest part of the job was attaching the gauge too the gas bottle as the gauge has to be screwed onto the bottle which in turn pierces the bottle seal. This took a fiddly few minutes but got there. Once attached I slowly opened up the gauge to allow a gas flow. My wife sat in the car and was able to tell me the air was rapidly cooling. Overall a good product and it does the job, but, the awkwardness of attaching the gauge could be a problem for some. Further Post 28/6/20. Having sat down and looked at the gauge I can see that if you open up the gauge it will allow screwing of the gas bottle too the connection on the gauge. I think I need to have a bit more patience in future.

Good stuff, but stupidly expensive nowadays.

These refills are useful to bring a car's AC back to life when its getting a bit tired and obviating the need to pay KwikFit or Halfords ~£60 for a regas. It's cheaper to get a 3 can set of this refrigerant than to buy them individually. Also, there's not a lot in a single can so you may need to use more than one. However, having bought and used a 3 can set, I needed an extra one for my daughter's Renault Captur. You will need a charging hose (R134A compatible) and you should use goggles and gloves. If you have a minor AC leak you may also want to use 'leak stopper' from the same manufacturer first. So, the expense can mount up. That said, the process is quick and easy and, in my case, the results are brilliant and my daughter has ice cold air from the car vents! She is pleased - and so am I. However, it is a tad disappointing how the price of these refills continues to rise - that's +30% in 6 months. It'll soon be cheaper just to go to KwikFit!

I had taken his car to the garage for a refill but was told his AC system had a leak so they couldn’t fix. It was going to be a costly job they said. After a bit of research on YouTube I found a guide on exactly the same car as his. https://youtu.be/kdIk_QPHshU Basically I had to buy three items. A fill pressure gauge / leak Sealant and then the gas. Followed the YouTube guide on how to fill and once done pressure was just below maximum recommended. So on this VW Polo the small can is perfect size. Only did it 2 days ago and my son was did a long drive in one of the hottest day of year so far and his car was cool with no need to open all the windows. Well worth the money as a refill would have been £80 and I now have the gauge. And would you believe my daughters Jeep has same AC problem so am going to check gas and system to see if can do same process on hers. 👍

Good item

Used this to top up my girlfriends air con. I have gauges and a vacuum pump. The gauges showed zero pressure in both low and high side. After vacuuming down the system and checking the vacuum held for 30 minutes, this confirmed no leaks. A further hour of vacuuming down ensured all moisture was boiled off. Having injected the correct grade and qty of PAG oil I then topped up with this refill can. The result was ice cold air con with a reading of 4.8 degrees C on my probe thermometer. Easy to use, cheap (for now until everybody starts using it), and gives great results. Highly recommended

Easy to use, it managed to reduce my air on temperature down from 22’ to about 11’. 51’F Which is an improvement, but still not as cold as it was with real R134 Gas. I will no opt book a group on for ATS tyres to service and regal it properly in the hope of hitting a magic 6-8 degrees. While it’s much better than it was it’s not like a proper machine that flushes the air and replaces it with gas.

Plucked up the courage to do this on my BMW E46 325ti sport. Looked up that this was the right re-fill/gas type (also on a sticker under the bonnet). I work on cars/houses a lot but obviously this has quite serious warnings consequences if you don’t do it properly. Plus I suffer with anxiety badly. I meant to do a video but forgot as I was so focussed on doing the job safely/properly. Air con was no cooler than the heater on the lowest setting so it’s been a struggle on the few v hot days we have had! So- A few google videos later- I put the air con & fans on full with engine on. Long sleeve top, surgical gloves & DIY type goggles 100%! Can cause frostbite or even blindness if there’s a leak. Then of course a high pressure cannister. Hence my anxiety! Connected the gauge to the ‘low side’ air con connection as instructed and checked it was secure. It will only fit this side not the high pressure side. Ensure the needle of the can connector is fully retracted and screw on the can at the other end. Slowly turn the pin ‘tap’ to pierce the can. You will see the pressure start to rise on the gauge then turn the tap so the point seals the can. It will drop to the actual pressure. Check the reading. Repeat as necessary. You want it in the blue zone, about 50psi was stipulated for my BMW. Now mine was on absolute zero pressure… The can was empty at about 35psi. However the air con is now blowing perfectly cold enough straight away. So it worked. Anyway, glad I did this (£40 with a £12.49 hose/gauge off here) as it shows the system is working. I am dubious as to whether there is a leak or something due to the zero read. I’ll see how it goes. Try a conditioner/leak stop next if it gets warmer quickly and repeat the process. I now feel confident doing it myself so that’s more £’s saved from now on. Never actually needed to do it before in 25 years driving. At least I know the main components don’t appear to be at fault. Fingers crossed. Then it becomes more expensive & complicated.
