How to shop for a portable air conditioning unit

Before you take a look around, you may want to think about where the portable air conditioning unit will go. How big is the room? This will tell you how much cooling power, which is measured in British Thermal Units (BTUs), you should look for. To keep your space cool, air conditioners should typically have around 20 BTUs per square foot, John McKeon, MD, CEO of Allergy Standards, previously told us.

To help you find the right model for your needs, EnergyStar, a federal program promoting energy-efficient products, offers the below cooling capacity guidelines on its website:

  • 5,000 to 6,000 BTUs: Cooling up to 250 square feet
  • 7,000 to 8,000 BTUs: Cooling from 250 square feet
  • 9,000 to 10,000 BTUs: Cooling from 350 square feet
  • 12,000 BTUs: Cooling from 450 square feet up to 550 square feet
