If you're looking for an attractive window air conditioner that can cool down an area up to 500 square feet in space then look no further than this popular 12,000 BTU model by Danby. This highly-efficient unit comes with an 11.3 Energy Efficiency Rating (EER) and its Energy Star-compliancy means it won't cost an arm and leg to run it. The environmentally-friendly R410A refrigerant used makes it an even more impressive appliance as does the clever energy saver switch which cycles the fan on and off when the compressor shuts down. The four-way air direction can be programmed either by the convenient remote control unit or the push-button electronic controls with an easy-to-read LED display feature. This classy unit will keep you comfortable in all conditions as it can be programmed via the variable electronic control for any temperature between 17(degree)C and 30(degree)C (62.6(degree)F and 86(degree)F). Sleeping is never a problem with this smart appliance due to the quiet 60-decibel operation and the sleep mode which prevents the room from dropping too cool at bedtime. You don't have to be home to make sure the unit is turned off as it can be programmed with the convenient automatic on/off feature to suit your schedule. The air conditioner also provides a 12-month warranty on parts and labour.
