  • 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.)

    • Number of Fan Speeds: 3
    • Airflow Rate: 0 cubic feet per minute
    • Remote Control: true
    • Integrated Heater: false
    • Sleep Mode: true (Enabling this mode sets the unit to first reach the desired temperature, then gradually increase the temperature over a period of time until it reaches a new set temperature, typically several degrees higher than the initial cool setting. This mode helps save energy while keeping the room comfortable.)
    • Timer: true
    • Auto Shut-Off: false (Feature automatically turns off the product.)
    • Energy Efficiency Ratio: 0 (The ratio of output BTUs (British Thermal Units) to input electrical energy (watts) at a given operating point. Generally, the higher the number, the more efficient the unit. Though higher efficiency units are typically more expensive upfront, they may offset the price in energy costs over time.)
    • Combined Energy Efficiency Ratio (CEER): 0 (The standard used to measure energy efficiency in window and room air conditioners by the Department of Energy (DOE) as of June of 2014. CEER measures the ratio of output BTUs (British Thermal Units) to input electrical energy (watts) in standby mode and while the unit is operating. Generally, the higher the number, the more efficient the unit. Though higher efficiency units are typically more expensive upfront, they may offset the price in energy costs over time.)

  • Rated 5 out of 5 stars

    Super, quiet, smart AC unit

    Got this for our 2 car garage workshop which is insulated but not perfectly. It keeps it cool, is quiet and very efficient. It’s absolutely fantastic. Smart controls too.

    Pretty good AC unit for larger areas

    After much research and comparing window AC units, I decided on this one and I am happy with my purchase. This one is definitely more quiet than other models I've had before in the 10K-12K BTU range, which is ultimately why I chose this unit. It doesn't blow air as hard as I would have expected for this size unit, but it gets the rooms cooled down eventually. (I use it to cool a small kitchen, hallways, and adjoining living room which total up to about 500 SF.)
