Here’s some must-know info for HVAC contractors: Quick Reference Data sheets. These technical guides, also called QRDs, are absolutely critical for charging our 13-SEER systems with Micro-Channel coils.

Contractors can find Quick Reference Data sheets on NORDYNE U > Technical Literature in the “Technical Specifications” category. For help on reading these sheets, check out our video below.
