  • Key Specs
    • Recommended Room Size: 1000 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: 18800 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: 300 cubic feet per minute
    • Remote Control: true
    • Integrated Heater: true
    • 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.)

    • Combined Energy Efficiency Ratio (CEER): 10.7 (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

    Great unit for price cooling oir our first floor.

    So far the air conditioner is working great, juat in time for a heat wave.. installation was a breeze as we already had the opening in wall from previous ac. Only issue was this unit has wider prings than old unit so hubbie had to run to electrical store to buy new outlet.

    Nice unit.

    I bought this unit mostly for the heater. It blows out hot air and has a powerful fan. It's quite and looks nice. I haven't used the air conditioner yet because I purchased it in late fall this year. It was delivered undamaged and within a week. I'm very pleased.
