What You’ll Learn:

• The fundamental differences between traditional single/two-stage systems and modern inverter equipment
• Essential pre-commissioning requirements including outdoor temperature (65-100°F) and indoor temperature (73-80°F) ranges
• Equipment-specific considerations for different brands, tonnages, and control types
• Proper charging methods and the critical 20-minute stabilization period
• How to access test/commissioning modes across various manufacturers
• Why “just turn the thermostat down to 60°” doesn’t work with inverters

Key Takeaways:

The presenters reveal a major industry problem: inconsistent and often incomplete commissioning information from manufacturers. They share their solution – a comprehensive spreadsheet compiled over months of research that provides startup instructions and commissioning details for nearly every inverter brand on the market.

The Challenge: Unlike traditional systems where technicians could confidently know a system was at 100% capacity, inverter systems require specific knowledge of how to properly test compressor speed, indoor fan operation, and outdoor fan modulation – information that’s often scattered across multiple manuals or hidden behind dealer portals.

This presentation is essential viewing for any HVAC technician working with modern equipment who wants to move beyond guesswork and return to confident, thorough system commissioning.
