Ac blows warm air. Is there a way to check the compressor to confirm it is operating correctly? And what purpose dose the compressor cluth serve? Is there something I should look for when the cluth is activated?
I attempted to put freon in aaand it aappears to be at capacity. Is there a method to confirm this as well?
Thank you james

If your ac is blowing warm it usually means it's a leak. Your compressor clutch should cycle off and on. If it's not doing this then either the pressure switch is bad. If you don't have a pressure guage you can't test the system to see if anything is in it. If you go by your evaporator while the ac is running the large pipe should be cool. If it's not its' not working. Have apro lok at it so you don't get hurt as you can messing around with this.
