The easy-to-install Emerson Quiet Kool 12,000 BTU through-the-wall air conditioner with remote control is the perfect cooling solution for your home or office. Designed for a room up to 550 square feet, convenient features include electronic controls with 3 speeds, flexible cooling options and a 24-hour on/off timer. This model is designed for through-the-wall installation and is not designed for standard window installation. It will fit most existing wall sleeves (including our competitors) and includes a decorative interior trim kit. A washable and reusable easy-access filter is an easy way to keep the unit running efficiently and alerts you when it's time to clean. You'll also enjoy quiet operation. At 53dB on low, this unit is among the quietest in the industry. This unit requires a special 230-volt/20-amp electrical outlet and will not operate with a standard 115V household electrical outlet. For peace of mind, you get our 1-2-5 years warranty: 1 year labor, 2 years parts and 5 years compressor. Emerson Quiet Kool air conditioners are a great way to beat the heat and stay comfortable.
