Keystone 12,000 BTU 115V Energy Star Window Air Conditioner

Product Overview

Stay cool with 12,000 BTUs of cooling power with the Keystone KSTAW12INV Window Air Conditioner with inverter technology. Designed for areas up to 550 sq. ft., it operates efficiently and carries the Energy Star rating.

Also available in a model with a heat pump, you can warm up spaces with 10,000 BTUs of heat when days grow cooler.

Multi-Mode Versatility

• Cool: Use this mode to set the cooling function, using the up/down buttons to select your desired temperature. Select from three fan speeds to stay comfortable.
• Dry: This allows your AC to operate as a dehumidifier, removing approximately 1.8 pints per hour. Some degree of cooling will continue; however, fan speed is not adjustable in this mode.
• Auto: When in this mode, cooling or fan-only operation is selected automatically, along with the best fan speed, to maintain your set temperature.
• Fan Only: Just like it sounds, this mode allows you to operate the fan by itself, for a refreshing breeze when days are not so hot, but you need air circulation.
• Heat: Set your desired temperature and then select your preferred fan speed for perfect warmth. You can operate the heat in temperatures down to 41° F. (model with heat pump only)

Additional money saving features include an energy saver mode, sleep mode, and a programmable 24-hour timer.
