Then if its not producing cold air, why are we looking for leaks instead of addressing the cooling part?

Add 1 ounce Freon to do audible check, if nothing heard, then
Fill system to full capacity with Freon. EPA allows a minor amount of leak for gauge connecting, and leak detecting. Then you get cold air.


I diagnose will full capacity of FREON. If it wont cool at that point, youve got more problems than a leak.

Once leak is found, promptly evacuate system and repair
