DIY aircon regas kits - any good?

I've got a Supra with no aircon. I had the system tested a couple of years back when it stopped working and the guy put some gas in and did a sniff test but couldn't find a leak (the car has been SORNed for the last 18 months).

 

I'd like to regas the system. Are the DIY kits any good?

I've used one on the Supra a few years back when the system was pretty much empty and not blowing any cold air at all. It worked fine and only took a few minutes to do - and only took part of one can. The type I used had a gauge on it to get the fill level about right.

 

That said, it doesn't cost hardly any more to get it done professionally. They suck anything that's left in the system out (including any moisture), pressure test it, then fill it with exactly the correct amount of refrigerant and lubricating oil. Many places do it for around £35 - £40. There's less risk of any damage that way and the system should then work as well as it possibly could.

Used the halfords ez chill. Did the job, just conect to the valve near the windscreen (L for low pressure on it) it's meant to have reparing qualities in it that plugs any small weak points in the system. Mine took a full can but only lasted one summer with fair amount of use. I'd go to a garage next time.
