(Product is not suitable for window installation). Perfect for large bedrooms, living rooms, or family rooms.

- FRONT-ACCESS FILTER: Let’s face it. Filters collect dust. With our front-access design, cleaning that dusty filter is a piece of cake. Simply pull it out, vacuum or rinse and dry, and slide back into place. No hassle and no disassembly required.
- GUARANTEED FIT: This air conditioner will fit in your existing 24.5” to 27” sleeve. We guarantee it. At 20.3” D x 24.2” W x 14.5” H, we provide the foam seals and installation kit necessary to retrofit your existing sleeve. If you don’t have a sleeve, the matching Keystone KSTSLV1 is also available for purchase (sold separately).
- ENERGY-CONSCIOUS OPTIONS: While there are 3 cooling modes and 3 fan speeds pre-programmed, you have flexibility. The Auto option will automatically ramp up and down the fan speed to keep you’re pre-set temperature constant. The Energy-saver mode conserves energy and saves you money by turning off the compressor once your desired temperature is reached.
