If you need to re gas your AC it’s leaking, leaks need to be repaired. Topping up a system with a hydrocarbon is not recommended, and could be problematic if the original leak is in the components in the cabinQuote:

You are right, any change of gas should be a full system change over. It is not uncommon for ac systems that are not sealed units to leak minute amounts of gas from the shaft seal, such systems will eventually need topping up i.e. servicing
such systems need leaking shaft seals or complete compressor changes to prevent the loss of a controlled substance i.e. repairs. Not being filled up with a substance they were not designed for.Quote:

These days,from about 20yrs ago,vehicles will often go a lifetime without needing any "top up" of refrigerant.
If a leak does develop,the leak will have to be located,and repaired,as per mandatory regulations.
As far as the Hychill minus 30 is concerned I'm a big fan... Been using it for years.
First used it in my Disco 2 V8 ES with duel A/C when I fitted a set of headers that melted a flexi hose to the compressor. A/C guy quoted me $1100 for the repair and a charge of 134a and THAT WAS AT MATES RATES[bawl].
That's when I found the Hychill product.
Well I had low expections cause it was so cheap. So I bought a second hand replacement flex line, didn't vac the system or replace the dryer, just purged the system with the Hychill and dropped in the rest 450g can.
It worked great. Nice and chilly and didn't have to touch till I sold the D2 4 years later. And being in Cairns the A/C is in use all the time.
So since then I have a vac pump and a decent set of gauges and I've done my RRC, my Jag and my Sigma (the right way this time with vacuuming out the system and replacing the dryers) and all is well.
I even did a mates car the other day and on the test drive the outlet temp in the cabin got down as far as 10 degrees. That's pretty impressive in the 30+ heat up here at the moment. And only $45 bucks for the can.
As far as worrying about it being flammable? Not worried a all. 400g of Hychill in the A/C or 80L of LPG in the boot of the Leyland! The 80L of LPG worries me more..
The issue I see with getting a professional in to do the work is they are restricted with what they can do. If your A/C needs regassed they are obliged to find and repair the leak before they can gas it up. If they don't they'll have an unhappy customer if it needs done again anytime soon that will trash them on Facebook.
Yeah, but no...
I hate to be a stick in the mud, but this stuff isn't something the home gamer should be doing.
To the letter of the law, you'd need to be a licensed Tradie with a refrigeration handling licence (RHL) to legally do that work, as even though hychill is an uncontrolled substance, its in a controlled system, and it's the components of that system which are also controlled [source]. Same as how I can buy all the stuff at Bunnings to wire my house but couldn't make all the connections.
The refrigeration law is set out in the Ozone Protection and Synthetic Greenhouse Gas Management Act 1989, and the Ozone Protection and Synthetic Greenhouse Gas Management Regulations 1995.
I still believe supporting a local fridgie is a better bet than trying to (successfully or otherwise) do this work yourself. The restrictions on them are not there for lining their own pockets, they are there as a part of a law, and environmental and safety best practice. As such, it's probably a bad idea doing it for others too...
Some reading. The fines can be outrageous, so don't poke the bear!
