  • 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: 18000 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.)

    • Combined Energy Efficiency Ratio (CEER): 11.8 (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.)

    Piece of junk, don't waste your time.

    Our Frigidaire 18,000 BTU went out after 5 years and we needed a replacement. Ordered this one thinking it would be a serviceable replacement but we were dead wrong. Thing ran for about 3 days before struggling to turn on. We thought we iced it over but fan won't turn on either. Controls work but nothing happens. Never heard of Keystone and I can see why. Should of stuck with my gut and went namebrand, will be exchanging for a whirlpool.

    Exceeded all expectations!

    After researching and reading several reviews I was hopeful this air conditioner would be a good replacement for one that lasted 17 years. This air conditioner has exceeded my expectations. It cools a very large area quickly but more importantly quietly. Delivery took longer than expected and needed to be scheduled by a delivery company. Easy to install and works great! And the price was fantastic!
