Air conditioning not working

When you say the air stopped working, do you mean the air is not longer cold or there is no air coming out of the vents?

The answer to this is a very different issue so we need to clarify that.

Here is a guide that will help and where we need to start if it is not blowing cold any longer. If there is no air then we need to look at the blower motor. Let's start with this and go from there. Thanks.

Yeah. The beeping sounds unrelated to the A/C issue so let's tackle that first and then we can start a new post for the beeping. We need to keep each topic to one issue so that others can find the solution to each if they search for it.

Here is a guide on how to add Freon that will help:

Let me know how you make out with this and we can go from there. Thanks

Okay. Does the compressor come on and off when it is doing this? The other thing we can do is check the pressures of the high and low system to see if it is properly charged and if the compressor is operating properly.

If the compressor is coming on and off, then we definitely need to check the pressures when this is running because depending on all this the compressor may be the issue.
