Air Con vent got "hissing" sound..

[PTC77]

recently when driving, can hear "hissing" sound from Air Con vent when blowing..  ..on off type...
is this the sign air con need top up?

[jonpaul0104]

no dun think so....how old is ur car? sounds more like a/c compressor going to up lorry....

if still under warranty, go back TCM soon.....

[vypez]

you can try topping up a/c gas, if not .... probably get your compressor checked.

I thought it is the aircon gas releasing?

[leolooi]

i would say is the compressor as well...cos mine last time also like this so got it change at TCM ...

But the aircon gas releasing also hissing sound. How do we know it is normal.

I got this hising sound oso in my car 2mths ago.
After a while, the air con was not cool anymore as all the gas leaked out.
TC says the cooling coil leaked.
To repair it will cost ard $1K if your car is out of warranty.
See previous threads on this issues.

If your car is just out of warrant, try to appeal and they might replace out of goodwill gesture

I'm getting this shrill hissing sound... is it the same as what u guys are talking about? 

[Midnight]

should we have a meetup, and hear each other hissing sound? 

really hard to confirm over here...

[jliow]

someone should use a video cam or sorts to record the sound.

Mine hissing go away when i press the aircon button to stop the compressor.
