Air Conditioning

[bigdatl]

I have a 94 Accord. Yesterday I was running the air in my car and I noticed the air getting warmer. When I stopped the car and turned off the air conditioner I noticed a sound like air escaping, sounds like it was coming from the dashboard near where the heater core is. The fans still work but I did not notice the compressor clutch clicking on - off. Is my AC dead?

If you hear the air hissing noise, the compressor is working, just the freon is too low.

So I just need to check for Leaks? It was working fine saturday. I did change the thermostat recently. Might that have anything to do with this?

Changing the thermostat will not affect the air conditioner. If the freon is low, the compressor will not engage. So was the hissing the sound of a freon leak? Could be. I don't know if the 94's use R-12 which is very expensive or R-134 which is cheap. The best way to determine if you have a leak is to do a vacuum check on the system. Guages are needed to find out if you have any gas in the system first. To find a leak will take a can of freon and a freon detector. This could be an expensive problem.

Thanks for all of the help. I will see if I can get someone to test the system for me. Do they perform ac test at Autozone or Advance?

Dude. I say go to Advanced Auto and get one of those freon canisters with the guage.

On a fairy hot day, turn on your car and turn on your A/C full blast cold. Let it sit for about 5 mins. Then follow the instructions on the can to fill the freon. The canisters contain chemicals that can help seal possible leaks as well. I did it to my car and my A/C got hella colder. Remember not to over fill the freon cuz that will cause it not to get cold also.

$20 a can, can't beat that!
