At Keystone, we prioritize your family's comfort. Our heat/cool 230V window air conditioner is designed with versatile supplemental heat when outdoor temperatures exceed 23 degrees Fahrenheit. Please note that this mode is meant to complement your primary heat source and should not be relied upon as the sole heat source. It is important to have a special 230-volt/25-amp electrical outlet for optimal operation, as this unit does not function with standard 115V household outlets. Our window air conditioner is equipped with money-saving features such as an energy saver mode, sleep mode, and a programmable 24-hour timer. With the convenience of our Follow Me LCD remote control, everyone can easily adjust settings and enjoy the blissful comfort provided by our unit. Choose Keystone for the ultimate in comfort and efficiency for your family. KSTHW18B
