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

Easy to use great value

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.

Pricey for the amount supplied but does the job.

Perfect and it does the job.

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!

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

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

This can is 226g if not less, and is definitely not 456g equivalent of r1234yf as stated on the can! My nissan qashqai requires 525g of r1234yf gas to be fully charged. So in theory i should only need x1.5 cans of this product to have it fully charged right! So i’ve used x2 cans so far and the system is still not fully charged yet, however some cold air is comming out! It makes more sense to say it is even less then 226g per can! I’ve just replaced the condenser so there is no leaks, and the system was empty so it was easy to check the amount required etc. Now i’ve bought 3rd can and hopefully it will be enough this time. If you think about how much it costs, it is not much cheaper than taking it to the garage and have it done there. X3 cans plus the gauge is about 120£! I regret it now, because for roughly the same price i could have it checked, topped up, new oil and cleaned as well. Just so you are aware.
