  • Key Specs
    • Recommended Room Size: 700 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: 14000 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.)

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 4 out of 5 stars

    Works great, but pay attention to detail

    I ordered a 15,000 BTU per the info on the website, however when it was delivered it showed a 14,000 BTU. I called customer support thinking the wrong item may have been delivered, but they told me the serial number registers to the 15K BTU and to look at the unit in the box and call back. As I desperately needed AC, I accepted the 14K BTU, and works great, but I think the website is misleading.
