    Keystone prioritizes your family's comfort, and our budget-friendly heat/cool 230V window air conditioner is designed to meet your needs. This versatile AC unit offers both efficient cooling and supplemental heat capability, serving as an additional heat source for outdoor temperatures above 23 degrees Fahrenheit. The heat mode is supplemental and cannot replace your primary heat source.
