He AC stopped blowing cold. I had it recharged last year

There are a number of things that could cause this, so we need to start with checking the pressure and finding out what is there. If you filled the system, then we can assume it has enough to turn the compressor on, but we need to confirm that first.

Here are some guides that will help with this:

I am attaching chart below that will help with figuring out possible causes based on the pressures.

If you don't have a gauge set then you can rent them from a local parts store because if adding freon did not get it to blow cold it may be overcharged at this point so pressures must be the first step.

Once we know what they are, please consult the chart for possible causes. Let us know what you find, and we can go from there. Thanks
