I got the car with 56,000. Around 60,000 I started to notice my A/C will stop blowing cold. I’ve done an A/C recharge. It was a little low, not much, but even after it will some days just fine and other it just not blow cold? I was told that it’s the compressor.

It could be the compressor going out which is common, when the system starts blowing warm you need to connect a set of AC gauges and read the pressures. This will tell us if the compressor is working or not.

Also, you can grasp the outlet tube, which is the larger of the two-line coming from the firewall which can help us determine if the problem is from the HVAC control or actuators. Here is how to change out the compressor in case you need it. Check out the images (below). Let us know what happens and please upload pictures or videos of the problem so we can see what's going on.
