With reliable air conditioning units, Keystone produces consistent cooling to keep you comfortable, even on the hottest days. This 8,000 BTU window-mounted air conditioner can effectively cool rooms up to 350 square feet with dehumidification up to 1.1 pints per hour to remove moisture from the air. A 7,000 BTU heat pump is also included for those chilly days. It features special Inverter technology to eliminate wasted operation in the air conditioner by controlling the motor speed to exactly the amount of power that is needed to keep the room at the desired temperature. A remote is included so you can control your cooling from across the room. Money saving features include energy saver mode, sleep mode, and a programmable 24-hour timer. You'll know when it's time to easily remove and clean the mesh filter with the Check Filter alert. Keystone not only provides a 1-year warranty but ensures that you stay cool and comfortable at a cost-conscious price.
