Hands-On Heat Pump Inverter Technology Training

This five-day hands-on course is designed to provide HVAC professionals with a deep understanding of modern inverter-driven heat pump systems – one of the fastest-growing technologies in the heating and cooling industry. Participants will learn how inverter systems operate, how they differ from traditional fixed-speed equipment, and how to diagnose, install, and service them safely and effectively. Through a mix of classroom instruction and extensive lab training, attendees will work with live inverter systems to explore variable-speed compressors, electronic expansion valves, communication controls, and advanced diagnostic tools.

Funding Opportunity: This class is approved by Penn Heat Pump Pathways. If your company and/or employee resides in Pennsylvania, then you are eligible for benefits. Contact PPATEC at training@papetroleum.org to learn more.
