At Keystone, we prioritize your family’s comfort. Our budget-friendly heat/cool 115V window/wall air conditioner is designed to meet your needs. With a removable chassis, you have the flexibility to install it either in a window or through an exterior wall. We’ve included an adjustable window kit for easy window installation, while wall installation can be done using an existing compatible wall sleeve or our separately available one. This versatile AC unit not only provides efficient cooling but also offers supplemental heat capability. It serves as an additional heat source when outdoor temperatures rise above 23 degrees Fahrenheit, complementing your main heat source. Please note that this mode is meant to supplement, not replace, your primary heat source. You’ll find plenty of money-saving features in this multi-seasonal unit. Take advantage of the energy saver mode, sleep mode, and programmable 24-hour timer to customize your cooling and heating preferences according to your schedule. Additionally, our Follow Me LCD remote control ensures total convenience, allowing everyone to relax in blissful comfort. Keystone is committed to providing you with quality products and exceptional value. Invest in our heat/cool 115V window/wall air conditioner and enjoy year-round comfort and cost savings for your family.
