Large Room Window Air Conditioners (12,000+ BTUs)

Lifestyle: Window Air Conditioners

These window air conditioners are ideal for residential and, in some cases, light commercial cooling. They use anywhere from 12,000 to 18,500 BTUs of cooling power and can typically cover between 700 and 1,000 square feet. These window AC models are best for cooling large rooms and office areas, living rooms, and apartments. Environmental factors that influence cooling areas include ceiling height (the estimate assumes a traditional 8-foot ceiling height), the amount of sunlight present in the space, the number of room occupants, and the number of heat-generating appliances in the space. If you have questions about how to choose the right size window air conditioner for your space, don't hesitate to call our product experts at 1-800-934-9194.
