  • 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: true

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.)

    Great AC

    Arrived on time with no damage, and works great, cools the room real nicely and the Sleep features have been handy. However, worth mentioning that I obtained this AC at a discount that rounded the final price to 618 approximately so my value for this may vary.

    Solid unit!

    This unit was purchased to help cool off 300 sqft of upstairs of an almost century old home with poor central ac to the top unit. It is far exceeding that capability and effectively and easily cooling over 700 sq ft. Inverters are the way to go for quick efficent cooling!
