2. Practice on Known Systems

• Before testing customer homes, practice airflow and pressure measurements on your own home, office, or shop
• Practicing on known systems will help refine techniques and interpretation of results, improving diagnostic accuracy.

3. Educate Homeowners on the Benefits

• Explain how measuring system performance can lead to greater comfort and efficiency
• Demonstrate how small changes — like sealing duct leaks or balancing supply and return airflows — can significantly improve energy use and comfort.

The Future of HVAC is High-Performance Based

The HVAC industry is evolving. As equipment efficiencies plateau, actual gains will come from optimizing system performance through airflow management, pressure control, and whole-home diagnostics.

Contractors who adopt a high-performance approach will improve their customers’ comfort and energy efficiency and set themselves apart as true industry experts.

By shifting our focus beyond equipment and embracing the principles of airflow and pressure management, we can transform the way HVAC systems operate—ensuring every component works in harmony to deliver the best possible results.
