The Truth About Inverter Heat Pumps: Failures, Commissioning & Real-World Performance with Tim De Stasio

Why are inverter heat pumps failing in real homes and what can HVAC pros do to fix it?

In this episode of the HVAC ADHD Vodcast, host Jeremy Begley sits down with HVAC veteran, consultant, and Comfort Science Solutions founder Tim De Stasio to unpack the real-world challenges of inverter heat pumps, energy efficiency, commissioning, and system design.

Tim brings 25+ years of hands-on experience as a technician, contractor, designer, and instructor. Together, he and Jeremy dig into the hidden problems behind inverter failures, poor dehumidification, communication-protocol limitations, and why so many “high-end” systems still perform poorly when installed or commissioned incorrectly.

You’ll learn:

• The truth about inverter heat pump reliability and part costs
• Why energy efficiency often comes at the cost of proper dehumidification
• How better design and field feedback can eliminate callbacks
• Why ongoing contractor training is the only path forward

Tim also shares insights on his HVAC design, consulting, and training work. Plus, you’ll learn his CourseCareers HVAC fundamentals training and his Comfort Science Solutions resources.

This is a must-listen for HVAC contractors, home performance pros, and anyone designing or commissioning inverter heat pump systems.
