I have my car AC service for like 6 months ago. My AC always blows out cold air whether or not I turn on my AC. But now I did not get the cool/cold air, but only warm air when AC is on or off

Any advice appreciated.

Hi hocsinh,

Without AC on how to get cool air? I am a confused.

Check for compressor operations with AC on.

Check positioning of venting system.

Check heater control cable adjustment.

The AC is on

the compressor is running when I checked

the air is warm whether or not the vent is on or off

i can hear some kind of noise from the passenger's side. Is that meant there is a leak?

What else should I check?

Thanks.

Hi hocsinh,

If there is noise from the passenger side, could be the expansion valve.

Get a pressure test on the system and let us know the readings.

Another mechanic checked and told me the leak is coming from the AC evaporator and it would cost $690 to fix it.

I am not sure who is to believe?

Any suggestion?

Thanks!

Hi hocsinh,

Sorry I can't help you about the price. But the pipe repair should cost less.

Since 2 person have told you 2 different possibilities, you might need a 3rd opinion.
