  • 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 Cool Settings: 4
    • Number of Fan Speeds: 3
    • Airflow Rate: 279 cubic feet per minute
    • Remote Control: false
    • 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.)
    • Timer: false
    • Auto Shut-Off: false (Feature automatically turns off the product.)
    • Energy Efficiency Ratio: 10.9 (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): 10.9 (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.)
    • App Compatible: false (The product can be connected to a program or software application on a mobile device, which then receives collected data from the product.)
    • Wireless Connectivity: None (The manner in which a device sends data to another device over a short distance without the use of wires or cables.)

Q: are you kidding 7 inch cord

A: I think it's a misprint, mine is just short of 6 feet.

Q: Hi this unit does run on 115 120 I hope

A: This will not run 115, this is for 220V.

Q: Is the heater function a heat pump or resistance coils?

A: While I cannot give you a 100% certified accurate answer, just know that for this price you can be pretty sure it is resistance heating. All of the window units that I have seen in this price range use this method of heating. Pricier units may have a heat pump.
