A Deep Dive with Ed Janowiak

In this episode, we sit down with Ed Janowiak (ACCA’s Manager of HVAC Design Education) to explore his journey of measuring heat pump performance. Ed shares how he first began exploring airflow and BTU calculations, and how the same challenges contractors face today were already present decades ago. We also cover practical ways to measure coefficient of performance and quick diagnostic tests that can give valuable insights into system health. Whether you’re a veteran or just getting started, Ed’s perspective shows why mastering the fundamentals of measurement is the key to solving comfort issues that never seem to go away.
