With reliable air conditioning, Keystone produces consistent cooling to keep you comfortable, even on the hottest days. Whether installed in a window or through-the-wall, this 8,000 BTU / 3,500 BTU supplemental heating capacity air conditioning unit can effectively cool rooms up to 350 square feet with dehumidification up to 1.9 pints per hour to remove moisture from the air. Perfect for smaller-sized living spaces like apartments, dorm rooms, sheds, and much more. Supplemental Heating mode is meant to be operated when temperatures outside are between 23 and 76 degrees. This mode is supplemental and NOT meant as a primary heat source. The unit features a unique remote with a thermostat built in to sense the temperature of the room, displays it on the remote's LCD screen, and sends a signal to your AC unit every 3 minutes for accurate cooling. 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.
