Before making a purchase, always consider the Energy Efficiency Ratio (EER) and British Thermal Units (BTUs) of the unit. The EER indicates how energy-efficient the air conditioner is, and the BTUs determine its cooling capacity. For a 220 sq.ft. room, you'd generally want an AC unit with around 6,000 to 8,000 BTUs.
Remember to read customer reviews and compare specifications to find the best window air conditioner that fits your needs and budget. Additionally, if possible, look for units that have an Energy Star certification, as they meet strict energy efficiency guidelines set by the U.S. Environmental Protection Agency (EPA).
