FAQ:

Q: What is the highest rated window air conditioner?

Q: What is the best portable air conditioner?

A: Whynter ARC-14S. Topping our list as the overall best portable ac unit is the Whynter ARC-14S, a combination air conditioner, dehumidifier and air purifier that is perfect for making your home more comfortable and healthier.

Q: What size window air conditioner do I Need?

A: As a rule of thumb, an air conditioner needs 20 Btu for each square foot of living space. But other considerations, such as the ceiling height and the size of your windows and doorways, might call for more cooling power. To measure your room, multiply the length of the room by the width.

Q: Does a window air conditioner have to go in a window?

A: Window air conditioning units must be installed in a window so that the back of the unit is outdoors. The outdoor part of the unit brings in fresh air and pushes out hot air. Central air conditioning units operate in a similar manner as window units.
