The Go-to Option for New Construction or Retrofits

YORK® Sun™ Core Rooftop Units save time, money and materials by fitting directly on preexisting, competitive curbs without the need for a transition. With two cabinet sizes that fit perfectly within many existing unit footprints, YORK® Sun™ Core Rooftop HVAC Units simplify the transition process by avoiding material, labor and height restrictions that transition curb solutions typically encounter. Configurations with cooling, gas heating or electric heat provide even more options.


Maximized Efficiency

YORK® Sun™ Core Rooftop Units can significantly cut energy costs compared to older units and feature a scroll compressor for improved efficiency.

Confidence Guaranteed
