A/C Hissing Noise?

A few days ago my A/C started making a pretty loud hissing noise, the best way I can describe it is if you opened the valve on a tank of propane gas, that sort of hissing noise it makes.
Since this started happening the A/C no longer works, I dont really care right now because its cool out since its fall, but I would like to know what I need to look into doing to get it working again for the summer. Thanks!

Re: A/C Hissing Noise?

Is it in the cabin, or under the hood somewhere?

Re: A/C Hissing Noise?

Sounds like you have/ had a leak and you no longer have any refrigerant in your system.

Re: A/C Hissing Noise?

On a side note if you heard it leaking, it should be easy to find.

Re: A/C Hissing Noise?

Did the sound come from the vents or from outside the vehicle?
I had my AC condenser pierced by hitting a small a$$ bird. The condenser is pretty exposed to say the least and could easily(though probably 1 in a 10.000) get punktured by some flying stones or gravel.
If you could determinate where the hissing sound came from it would make it much more simple to deal with.

Good luck!!

Re: A/C Hissing Noise?

Your freon 134a is low, and you are hearing the gas in the expansion valve. I had that happen on a Dodge minivan last summer when the freon was low. After a charge it was fine. You may have a small leak.
