12,000 BTU Window-Wall Air Conditioner with Heating and Dehumidification for Medium Sized Rooms up to 550 Sq.Ft. (230V)

Keystone is committed to ensuring your family’s comfort with our budget-friendly heat/cool 230V window/wall air conditioner, expertly designed to cater to your needs. Featuring a removable chassis, this unit can be installed either in a window or through an exterior wall with the adjustable window kit included. If you opt for wall installation, you can use an existing compatible wall sleeve or purchase one of ours separately.

This versatile air conditioning unit not only delivers efficient cooling but also offers supplemental heating, making it a reliable heat source when outdoor temperatures rise above 23 degrees Fahrenheit. However, please keep in mind that the heating mode is meant to supplement, not replace, your primary heat source. It’s important to note that this unit requires a dedicated 230-volt/20-amp electrical outlet and will not function with a standard 115V household outlet.

Maximize your energy savings with features like energy saver mode, sleep mode, and a programmable 24-hour timer. These options enable you to tailor your heating and cooling according to your schedule, effectively reducing energy consumption and costs. The included Follow Me LCD remote control adds to the convenience, ensuring that everyone in your family can relax comfortably.

Investing in our heat/cool 230V window/wall air conditioner means you can enjoy year-round comfort. With Keystone, your family's comfort truly begins here.
