Great stuff I am in Rotherham so if he is any good then please post or pm me with his details



Hope he does a good job !!

Do it yourself its easy. You can buy the gas from halford's. It comes in a type of aerosol with a connecting pipe. You just connect it to the valve on the aircon and Robert is your mother's brother!

I have to admit I thought the air con thing was an expert only type of operation, doesn’t the entire system have to be pressure checked and aren’t there legal considerations about disposal of some of the older gases.
If you can do it yourself guess what my first job is going to be. Mines needed doing for ages

If the system has gas in it how are you going to know how much more it needs? how are you going to know if there is any air in the system?

If the system is empty how are you going to leak test it? and vauum the air and moisture from it?

Diy air con gas costs about £49 A service by a air con specialist costs about £50 to £80 that inc leak test, deep vacuum, oil and gas do you realy want to risk a £600 comp for this small saving

I have been having trouble trying to find an aircon company to recharge my '89 Pajero after changing the compressor, as it uses the 'old' R12 gas.

I finally decided to do it myself and bought the drop in cartridge of R12 gas from Autokool in Worksop, Notts by mail order (or was it eBay, I forget). Any way, rapid service ensued and a good product - nearly a kilo of refrigerant, the requisite pipes and connectors arrived and twenty minutes later, it's done and the car is cooling down nicely even in our current 30degree heatwave.

Thinking about it, I don't think you can over-gas the system, as the pressures in the can and in the system will equalise and so you won't be able to put more pressure in the A/C system than the pressure in the aerosol. You may be left with a little in the aerosol, if you already have some in the system - I didn't .

About the legal side - the gas R12 is not an ozone-depleting refrigerant, it was discontinued for other reasons, I believe. also the offences under EPA only apply to businesses, not to individuals, so if your system happens to leak out all its gas, you are not committing an offence, RELAX!

The website is www.car-air-conditioning-supplies.co.uk and the e-mail address is chris@stott90.freeserve.co.uk

Mention my name if you use them - maybe I'll get discount on my next order : )

Oh yes, the cost was £49.99 plus £7.75 P & P which is a little less than what I would have paid to get it done professionally, plus I avoided the hassle of trying to find someone and I got the satisfaction of doing it myself.

PS The instructions are vague, but remember to run the engine and switch the A/C on to charge the system and the inlet pipe is the wider one of the two

Hope you're running COOOOLer now.

Hi John

Interested to see you managed to get your A/c back up and running with a DIY kit.

I have a 1995 Shogun with 134a A/c, which doesn't cool, so I too would like to try the top up option first.

Where do you connect top up cylinder and what type of connections are required.

Various kits available on the site you kindly provided a link to.

Which one did you get/do I need??

Many questions,

Mark

nitroflight ,
The company is Cool Comfort uk ltd www.coolcomfort.co.uk
mob 07889 300384 Paul Aizporietis.
they are in the yellow pages.

They came to do mine today but when he pressurised the system he found a damaged pipe so he couldn,t regas the system.So here are a few questions for you aircon experts .
1.The pipe that is damaged is the smaller of the 2 and runs to the back aircon , it is leaking just behind the rear near side wheel .
Where can i get another pipe from .
Or can i get the damaged section out and have a new piece put in with new threaded ends
2. Looking at the pipes underneath there is a joint on both pipes at about half way down lengh of car and before damaged part , if i uncoupled these joints and blanked them off so nothing is going to the rear , would i then be able to regas the system but only to use the front air con , Or would i have to couple the 2 pipes (large and small) together for a to create a return flow .
Hope this makes sense.
Heppy

Firstly this post is not intended to flame anybody it is just I re-charge/repair vehicle air con for a living and see the damage that is done when the job has not been sorted right I'm just pointing out that it is not as simple as is made out

If the system has not been vacuumed then your system will have air and moisture in it as air is a non-condensable gas it will push up the pressure in the system, a system with moisure in it will never give a steady pressure if you connect gauges to it you will see the needles dancing up and down on the pressure not sitting steady as they should

You can over pressure the system because with the engine running the comp is pulling in the gas to the system and the aerosol will not equalise the comp will pull till there is nothing left in the can

(About the legal side - the gas R12 is not an ozone-depleting refrigerant)
R12 is a CFC refrigerant (ChloroFluoroCarbon). It consists of Chlorine, Fluorine and Carbon. The chemical symbol CCI2F2. We used to see the CFC sign on the back of cans of aerosols, the CFC being used as a propellant to release the contents of the can. R12 CFC has been banned from being used in the EU (European Union) for the majority of uses it was designed for, vehicle air conditioning systems that still have R12 in them are allowed to operate. If these systems need to be serviced, you must remove the R12 and NOT re-use it.
This refrigerant damages the ozone layer - it is the chlorine content of the refrigerant that causes the depletion of the ozone.

BS4434 section 3, subsection 6, paragraph 2, note 3 states: "It is an offence under sections 33 (1) c and 34 of the EPA Act 1990 (chapter 43) to deliberately discharge environmentally damaging refrigerant to the atmosphere" so if your system happens to leak out all its gas, you are not committing an offence this is true but how do you leak test it ?
Deliberately venting could be construed as filling a system with refrigerant initially to find a leak. this apply to businesses and individuals

heppy look at this thead for the pipe http://www.pocuk.com/forums/viewtopic.php?t=30575 DO NOT CONNECT THE PIPES TOGETHER 1 is low pressure and the other is high pressure

Anyway thats enough from me I just thought members should see both side so they have all the facts to help them deside which way to go

i am with you on this , if i hadn,t had the aircon expert out today i woudn,t have known i had a damaged pipe and would have wasted £50 on a diy fill only for it to gradually leak out again . the equipment he had to do the job correctly certanly was not for the amature diy-er
Going back to the 2 pipes ,if i just blanked both pipes off as mentioned at the joints before damaged one would i still be able to use my front air con once regassed up as a tempory measure till i got a new pipe .

cheers for reply Heppy

[Sam-F]

If you want to blank them off go as close as you can to were they and the front pipes split and you will be ok but remember to tell your air con guy so he can charge it as a single system (less gas)

if anyone needs help find someone in your area that can help with your aircon try these sites
