Take the guesswork out of inverter heat pump systems. This two-hour session walks technicians and installers through the full lifecycle of an inverter air-to-air heat pump — from selecting and matching the right equipment to commissioning a properly running system. You'll leave with the practical knowledge to install, charge, and troubleshoot these systems with confidence.

What You'll Learn

• Equipment fundamentals — outdoor units, air handlers, coils, size changing, match-ups, and efficiency
• Outdoor unit installation, including menu navigation and key menu functions
• System charging, coil temperature selections, and dip switch configuration
• High-voltage considerations, intelligent diagnostics, and surge protection recommendations
• Line set limitations (length and diameter), intelligent oil return, and reusing existing line sets
• A complete system start-up checklist — coil, air handler, and outdoor unit checks, plus required clearances
• A full review to tie everything together

Who Should Take This Class

This class is ideal for HVAC technicians and installers who work with — or are preparing to work with — inverter air-to-air heat pump systems. Whether you're new to inverter technology and want a solid foundation, or you're an experienced tech looking to sharpen your installation, charging, and troubleshooting skills, you'll find practical, job-ready takeaways.

Refreshments will be provided.

Please note: This class does not offer continuing education (CE) hours.
