How to Do Vacuum in AC System Using Micron Gauge | Step-by-Step HVAC Tutorial | Animation

In this video, we’ll learn how to perform a vacuum using a Micron Gauge — the most accurate way to remove air and moisture from an AC or refrigeration system. We’ll go step-by-step through the entire process, from removing the valve core to achieving a perfect deep vacuum below 500 microns. You’ll also understand: ✅ Why we remove the valve core before vacuuming ✅ How to connect the micron gauge correctly ✅ What the micron readings mean (leak test, moisture check, deep vacuum) ✅ The difference between a standard and deep vacuum This method ensures your system is clean, dry, and leak-free before charging refrigerant — essential for system performance and reliability. 📘 Watch till the end to see how to check for leaks after vacuum and reinstall the valve core safely. 🎓 HVAC Course on Udemy: 👉 HVAC Fundamentals Course by Zebra Learnings https://www.udemy.com/course/hvac-fun... beginners-by-zebra-learnings/?couponCode=ZEBRA50 COUPON CODE - ZEBRA50 💰 Use the coupon code in the description for 50% OFF and start learning from Beginner to Pro level. 🔗 Related Videos: • Vacuum with Manifold Gauge →    • How to Vacuum an Indoor AC Unit: Step-by-S...   • PSIG vs PSIA | Gauge Pressure vs Absolute Pressure →    • PSIG vs PSIA | Gauge Pressure vs Absolute ...   👍 Like | 🔁 Share | 🔔 Subscribe to Zebra Learnings for more HVAC training videos!
