Info & Guides

For spaces as large as 550 square feet, the Keystone 12,000 BTU Inverter Window Air Conditioner offers efficient cooling plus dehumidification to keep you cool and dry. Energy-saving inverter technology, eco-mode, sleep mode, and a 24-hour timer combine to make this air conditioner ideal for efficiently battling summer heat.

 

Save Energy and Money

Inverter technology eliminates wasted operation by controlling the motor speed to exactly the amount of power needed to keep the room at the desired temperature. The energy-saving features of this 12,000 BTU window AC help save even more energy and money.

  • Energy Saver Mode: In this mode, the compressor shuts off while the fan continues to run. The fan turns on at 10-minute intervals to test the temperature, and when it falls below the set temperature, the compressor runs until the cool temperature is reached.
  • Programmable Timer: Use the 24-hour timer to program start and stop times so your space is cool when you arrive, but the system doesn’t run all day.
  • Sleep Mode: The set point gradually increases with the fan speed on the low setting for eight hours, saving energy while you enjoy a comfortable night's sleep.

Quiet and Powerful

The Keystone inverter window air conditioner operates more quietly than many similar ACs, reaching only 59 dB on high fan speed.

Its 12,000 BTUs of cooling power can keep the heat of summer at bay, and it features a FlashCool function for cooling down your space quickly. This function automatically sets the AC to maximum cooling and the highest fan speed at the touch of a button.

Additional Features

  • Dehumidification: To manage high humidity, use the Dry mode, which can remove up to 1.85 pints of moisture per hour.
  • Washable Air Filter: This filter is easy to access through the front of the AC. It captures large particles and can be quickly cleaned with water.
  • Refrigerant: This Keystone AC uses R-32, an earth-friendly refrigerant.
  • Washable Air Filter: Easy to access through the front of the AC, it captures large particles and can be quickly cleaned with water.
  • Window Requirements: The Keystone window AC fits double-hung windows 23-36 inches wide and measures 18.98 D x 14.65 H x 21.69 W inches.

Sylvane's Expert Take

The Keystone 12,000 BTU Window AC can meet customers’ expectations for efficient and effective cooling and dehumidifying rooms up to 550 square feet.

  • Full Installation Kit Included: Keystone makes installation easy with full instructions and includes the frame assembly, top rail, foam inserts, window sash seal foam, and all necessary screws and safety locks.
