Hi all, I had an issue with my air con today and was hoping to get some advice from you awesome people.

I was on my way home from work today and had the air con on when I noticed an odd whiring noise (kind of like a dodgy bearing I guess). The noise would increase as speed increased. When I turned off yhe air con, the noise stopped completely, so I'm almost certain it's something in the air con system causing it.

When I got home, I popped the bonnet and turned the air con on again to have a listen, but as I was getting out of the car there was a load of steam/escaping gas from the engine bay. The car still has coolent and it still run ok, but the air con light now flashes, so I'm thinking that was something in the air con system sprung a leak...

Do you have any ideas what the likely components are that I should need to check to get this resolved? Can I work on the air con system or does it need a specialist to do the work? Finally, any ideas what is the max this could cost me?

Thanks for any advice.

Where was the steam/ gas escaping from? sounds like a burst aircon pipe and you have lost your refrigerant gas so that will need fixed/ replaced then your system recharged.

If you have all the necessary tools for repair and if you know how to fix it would not be a problem. Otherwise, you can only do more damage. The facts:
1. Almost all this gas had leaked from the system is like to be Gas A404 or R32 (these gases normally support combustion but you are lucky that didn't ignite).
2. You should test the system with a detector for gas on connections or copper pipes. If the pipes are pierced then you should soldered with silver.
3. You also need device for vacuuming and gas A404 or R32 in the bottle with the appropriate connections with pressure gauges for that particular gas.
4. Of course this is the whole process if you know what you're doing (you have evaporator, expansion valve, compressor, condenser, drier this is basic system), the basic rule is never, never !!!! put the liquid on the suction side of the compressor.
My simple advice is let somebody else do it.( expert for A/C) The cost for the gas is around $200,00 45 kg bottle and for work depends from $50 to $400.

Unfortunately I didn't get the bonnet open in time to tell for certain where it came from, but I think it happened nearer the front of the engine...

Wow, I'm lucky it didn't ignite...

From that it sounds expensive to diagnose and it will need a specialist for that (I certainly don't have all of them tools at my disposal...
I guess I'd better get some quotes or get used to having the window open
