re-gassing air con??

The air-con in my 94 classic is pretty poor to be honest, it gets cold but i dont think it gets cold enough and its a bit intermittent (blows cool and cold). I've heard that you can get d.i.y kits to re-gas but i'm not sure if this is a job for the pro's and i dont want to balls it up?

cheers, Rich

Hi Rich,

As Ed said take it to a specialist. You really can't do this yourself safely. The refrigerant is under pressure and a specialist shop will have the proper equipment to safely discharge the system, recharge it to the right amount, and check it for leaks.

I've just had the same issue with my air con. Take it to the pro's would be my advice. It shouldn't need re-gassing unless its been leaking, and they've got all the gear for finding leaks.

Re: re-gassing air con??

hi i ran garages for 17 yrs that fitted and regassed air con
do not use the kits
the wreason is that you should vac the system down this will make sure you put the correct amount of gas in and it is very exact amounts and take moisture out of the reciever dryer
if you use the kits then i how much gas and it goes by weight plus a lot of kits have a additive in them which can seal slight leaks*** but the additive also damages the compressor in time and can block the expansion valve or oriface tube if its that type of system
the additive cannnot be flushed out i used 17 tins of flush @ 25 per tin retail to try to clean out a system on a audi and still not cleaned it fully
if the compressor is then taken of the oil in it stinks and nomater what chemicals are used still wont clean it <has to be as clean as a automatic gear box> plus all the pipes metal and the condensor and evaporator are contaminated ie all scrap
dont know of anybodt that will have a system to sell
i hope your system is r134a if you take of the charge port caps will have a quick release charge port
if its like a shriber valve then its r12a this can be charged once the system is converted to r134a again easy call motor climate in birmingham ask for bob in parts he will sell you a kit which is a special oli and two charge ports
have them fitted ? anthen when the system is vacumed out add the the oil and charge with 40% less gas than if it had been r12 dont try the other gasses avalable
if can help any more e mail me

sorry this was a long reply but if it does not help you maybe some one else
cheers phil

Re: re-gassing air con??

hi for got to say
you do loose some gas by natural leakage over time
you should use the sytem for 10 min per week or at least 30 min per month this allows the very small amout of oil that is in the system to go around and lubricate the seals this stops them drying out and then the gas says i am off thanks a lot lol
you should regas about every 2-3 years
you do have a sight glass but this is only for any use if r12a gas in the system
dont use it to check if r134a gas
phil
