Car AC Aircon R1234YF Air Con Air Conditioning Top Up Refill Regas DIY Gas Can

Easy to use great value

Used to successfully regas a Seat Mii 2019 where the air con was not working. I checked the low side pressure and it showed 40 PSI (both engine off and engine on, so compressor was not kicking in). If you follow the product instructions it says in this scenario DO NOT regas as you have a compressor fault. However, after some research I learnt that compressors have a pressure switch which stops the compressor running when system pressure is low. In my case simply increasing the pressure by adding the refrigerant got the compressor and the aircon going again. I fully regassed one car, reducing the vent temp from 25C to 4C then topped up a second car, reducing the vent temp from 25C to 3C.

Pricey for the amount supplied but does the job.

You need to do a full 60-minute evacuation of your AC system if you want to keep it healthy. Never just 'top it up', especially if you have actual R1234yf gas in your system—remember, this product is a 'better-than' DIY alternative mixture. Furthermore, take your time letting the mixture into your system slowly and in tiny amounts. You must ensure that only gas hits your compressor, not liquid! Because this is an alternative mixture, it does not match R1234yf in mass-to-volume ratio. Pay close attention to the 'equivalent mass' reading on the label; you will need to do the back-calculations to figure out the exact weight required for your specific car. Be careful when reading reviews for this product and do your research first. You don't want to end up forcing the wrong-sized valve on to the can (best-case scenario) or overcharging your system (worst-case scenario). Air conditioning systems are incredibly expensive to repair. However, if done properly, this product is excellent. The keys practically froze in the ignition of my Merc GLA ...well, almost! I have been using this brand for years and highly recommend it.

The garage wanted over £140 to recharge my aircon, last time they done it the year b4 and it didn't last, so decided to give it a go myself and bought this with the valve and easily found the lower pressure connector in my engine, followed the step by step instructions and had the full can emptied in under 20 seconds, jumped in the car, AirCON iCE cold and still is Months later, cannot believe these garages get away with charging so much for a 5 minute job that it took me. Never again will I let them rip me off for this, its dead easy to do!!!

I am very disappointed with the product. I have used it to fill in my car AC system but only for a few seconds and I shut off the valve by unscrewing the puncture needle of the hose to check the dynamic pressure, however, all of the gas leaked out of the can and I could not stop it, even though I had completely removed the hose from the can. I thought the canister was meant to have an internal stop valve which should have sealed off the gas from flowing out once the needle was out. It is a fire hazard! I could see an intense white smoke oozing out of the can laying on the ground and building up. I have used the following Charge Hose on your canister: R1234YF U-Charge Hose With Gauge, 1/2’’ Acme Left Hand Self-Sealing Can Tap Opener, For Automotive Air Conditioning Systems. Kind regards

My aircon had stopped working on my Golf, as I have used this before on my Daughters car and it worked well I decided to buy the same again. Arriving as always promtly using Amazon Prime I was only without my A/C for a few days. This is simple to use and easy to follow the instructions provided. The A/C system was completely empty so I used up the whole can of refrigderant . I had a look at a few You Tube videos to get an idea what to do the first time I did it. A 10 minute job in total and saves you some time taking the car to the garage and also the expense!

A garage quoted me £70 to regass my air con so brought gauge and gas for half the price and did it myself air con works great
