Charging by the QRD


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. These air conditioners are very sensitive to an overcharge, so the QRD is necessary to make sure the charge is done properly.

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.
