High-efficiency HVAC motors are supposed to save energy and improve comfort. But the ugly truth is, their performance in the field doesn’t always match what’s promised on the label. In this video, I break down the three main types of blower motors — PSC, constant torque ECM, and variable speed ECM — and show how each one really behaves under static pressure and duct conditions.
Whether you’re a new tech trying to understand motor behavior, or a homeowner who just bought a “high efficiency” system, this video explains why real-world efficiency often comes down to ductwork and airflow — not just the SEER rating on the box.
👉 What You’ll Learn in This Video:
How PSC, constant torque, and variable speed motors actually work
Why motors react differently to static pressure
How efficiency ratings (SEER and SEER2) are tested vs. what happens in the field
Why duct design makes or breaks system efficiency
The “efficiency trap” most people don’t realize they’re falling into.
