  • Key Specs
    • Recommended Room Size: 550 square feet (The recommended area size in which the product is designed to operate and produce optimal results, such as the desired heating or cooling. Generally, running a unit too big or too small for the space will result in ineffective operation and wasted energy.)
    • BTU Cooling Rating: 12000 british thermal units (The amount of BTUs (British Thermal Units) per hour the unit uses to cool the air, also known as cooling capacity. For best results, the capacity of the unit should be based on the size of the area it is intended to cool. For example, a 5,000 BTU capacity works optimally for a 150 square foot room. In general, an oversized unit will not effectively remove humidity, and an undersized unit will not cool the space efficiently.)

    WALL AC perfect addition

    WALL AC unit makes a huge difference! We’ve always used window ac units and there is a HUGE difference! I bought 2 for the 2 wall sleeves that covers my entire house. Like any other unit they are noisy. They cool down the area in minutes. I live in CT, I keep my house at 60 year round. (The units go to 61) The day we set them up it was almost 80 outside and I was shivering inside after them being installed. These will save me money due to them being so efficient.
