About This Product

Keep your space cool and comfortable with this Keystone through-the-wall air conditioning unit. Designed to cool rooms up to 450 sq. ft., this 10,000 BTU air conditioner delivers efficient cooling. The dehumidification feature eliminates up to 2.3 pints of moisture per hour to improve air quality. It provides a supplemental heating capacity of 10,600 BTU, making it perfect for smaller living spaces such as apartments, dorm rooms and sheds. Since this unit is not meant as a primary heat source, use the supplemental heating mode when outdoor temperatures range from 23 to 76 degrees Fahrenheit. A built-in thermostat accurately senses the room temperature, displays it on the included remote's LCD screen and communicates with the AC unit every three minutes to enable precise cooling. The energy saver mode, sleep mode and programmable 24-hour timer help lower electricity costs. To ensure optimal performance, it offers a Check Filter alert to remind you to clean the mesh filter. This air conditioner requires a special 230V/20-amp electrical outlet and is incompatible with a standard 115V household electrical outlet.

      Does unit come with a sleeve? Can I have someone install and take my old unit out
      BySep 3, 2026
      1 Answer | 
      Answer This Question

      Hello, The wall sleeve is a separate item as it is not always needed for every install. We are a non-servicing manufacturer, but Home Depot may have some recommendations for an installer in your area. Thank you!

                  Easy install, works well to keep small one bedroom one bath apartment cool. Haven’t had it during winter yet so not sure on heat capabilities. Don’t like the over exposed back, feel like the screen is to large and will have to contend with outside debris causing issues.

                  ⭐️⭐️⭐️ Excellent year-round comfort solution!
                  [This review was collected as part of a promotion.] I’m very impressed with the Keystone KSTAT10-2HD. The performance is top-notch; it cools my 450 sq.ft. room quickly and the heat function is a great bonus. While it has some serious weight to it, that just reflects its solid build and durability. The installation trough the wall was straightforward with the included kit, and the unit looks very professional once set up. Maintenance is also simple, as the filter is easy to access and clean. It’s a powerful, well-built unit that I’d highly recommend for any small apartment or office.

                    Received damaged (home delivery). Thank you Fedex. I’m glad i could return it…

                      Easy installation and good cooling so far I purchased two Keystone through-the-wall air conditioners with heat and installed them in the recommended sleeves. Once unboxed, both were installed within minutes. The directions were clear and easy to follow. Each unit serves a 120-square-foot space. They do struggle to cool things down quickly when the space gets really hot, but if you stay ahead of the heat and manage the cooling, they work great. I haven’t tested the heat function yet, but I’m hopeful it will be just as straightforward. So far, I’m pleased with both units. Ask me again in a year
