My A/C isn't working, it's blowing hot air out and I'm not sure where I start to diagnose. I can tell you it's not low on refrigerant at all. What is recommended and what process do most people use?

Good afternoon,

You need a set of gauges to check both the high and low side pressures.

How do you know the Freon is full?

I checked it with one of the gauges that comes with an AC Pro.

That's not an indicator. You need a real set of gauges to check the pressures.

You can rent or buy a cheap set to check the pressures.
