This Keystone 12,000 BTU / 10,600 BTU supplemental heating capacity air conditioning unit can be easily installed through-the-wall. With its powerful cooling capabilities, this AC unit cools rooms up to 550 square feet. Additionally, its dehumidification function removes up to 2.5 pints of moisture per hour, creating a more comfortable indoor environment by reducing humidity levels. This unit includes a supplemental heating mode. However, please note that the heating mode is meant to supplement the primary heat source and should be operated when temperatures outside are between 23 and 76 degrees Fahrenheit. The remote control features a built-in thermostat that senses the room temperature.
