How To Make Every Room Comfortable With Better Airflow

Having airflow issues? Don’t just crank up the blower speed — diagnose the real cause first.
🛠 Tools I’m Using in This Video:
– UEI EM201SP Manometer (manometer only): https://amzn.to/4mrxzIl
– Full UEI EM201SPKIT Static Pressure Kit (tubes, fittings, probes, etc.): https://amzn.to/4pwEBhN

In this video, I show you exactly how to measure static pressure, break it down into the filter, coil, and ductwork, and figure out where your airflow problems are actually coming from.

This 100 year old house has an old duct system with long runs and retrofit obstacles — I’ll show you how that impacts pressure and airflow, and why blindly adjusting blower speed could make the problem worse.

✅ Learn how to:
– Measure total static pressure properly
– Separate filter, coil, and duct pressure drops
– Avoid making airflow worse by increasing blower speed
– Understand why long runs struggle and short runs dominate
– Set up your system for real airflow balancing

📐 Whether you're a tech or a homeowner, this is the clearest walkthrough on duct diagnostics and balancing you’ll find.
