Find the Right Window Air Conditioner for Your Home

Window unit air conditioners are popular because they offer an efficient, low-maintenance way to keep your home cool. While many portable air conditioners need to be emptied by hand or occupy valuable floor space, casement window air conditioners automatically move moisture outside for an easy-care option.

When shopping for an air conditioner for a sliding window, consider the size of the room where you'll install the AC. You'll notice that each window AC unit lists a BTU number, which measures how much heat the window AC unit can remove per hour. Follow these simple guidelines to match the size of your room to the best BTU measurement:

• 100 – 350 square feet: 5,000 – 8,000 BTU
• 350 – 550 square feet: 9,000 – 12,000 BTU
• 550 – 1,000 square feet: 14,000 – 18,000 BTU
• 1,000 – 1,500 square feet: 18,000 – 24,000 BTU
