How we uncover the best portable air conditioners

We assess every portable air conditioner we test under lab conditions. Our test scores are based on measurements taken from a team of experts that keep a close eye on the features that matter the most.

To find out which portable air conditioners deserve a spot in your home, we look at:

  • Performance: Which?-recommended models won't take long to get your room down to a comfortable temperature.
  • Airflow speed distribution: For a portable air conditioner to earn Best Buy status, airflow speeds need to be consistent no matter how far away you are from the machine.
  • Ease of use: Dealing with a portable air conditioner that takes an age to set up is a real pain – we're speaking from experience. Our lab experts consider how well the air conditioner's parts fit together, also looking at the instructions that come bundled with each model.
  • Accuracy of cooling efficiency claims: Brands make promises all the time, so we check to see if the cooling power you'll get from the machine matches the claims made by its makers. If not, you'll be the first to know about it.
  • Noise: You'll no doubt prefer a quiet portable air conditioner over a machine that rattles and whines every time it's turned on.

But our list of checks doesn't end there. Although these features don't factor into our final test score, we also measure the number of fan speeds and the dimensions of every portable air conditioner we review.

Which? portable air conditioner tests are different. Our test scores are based on measurements and ratings supplied by a full team of experts at our lab, ensuring there is no room for unconscious bias when giving an overall rating.
