THE PROFESSOR HAS A REMINDER FOR YOU…
❌ “Just add gas.”
❌ “Airflow doesn’t matter.”
Two phrases that can turn a simple service call into an expensive lesson.
Low pressures don’t automatically mean low refrigerant. Before reaching for the jug, you need to understand what the entire system is telling you.
✅ Check airflow.
✅ Measure static pressure.
✅ Verify superheat and subcooling.
✅ Look at the whole picture.
Because good diagnostics aren’t about finding a number you don’t like and immediately trying to change it. They’re about measuring, verifying, and understanding WHY that number is there.
That’s what Professor Pickel has been preaching since the beginning:
MEASURE. VERIFY. TEACH.
Because guessing is expensive.
And that’s exactly the mindset we build at Anthony’s Cool School. We’re not teaching students to memorize shortcuts. We’re teaching them how to think like technicians.
