What's behind our air conditioner Ratings?

Experts at our National Testing and Research Center tested 43 models in air conditioners to see which ones perform best.

We look for:

Overall score
This is based mainly on comfort, noise, and energy efficiency. The displayed score is out of a total of 100 points.
Comfort
This is how well temperature and humidity are controlled at the low-cool setting. The best performers held temperatures to within one-and-a-half degrees of the setpoint.
Indoor noise low
This judgment of indoor noise at the low-cool setting combines an objective measurement of noise level using a decibel meter with a subjective assessment of noise quality (how annoying or grating the particular sounds were).
Indoor noise high
This judgment of indoor noise at the high-cool setting combines an objective measurement of noise level using a decibel meter with a subjective assessment of noise quality (how annoying or grating the particular sounds were).
Brownout
Gauges the unit's ability to run and restart during extreme heat and low voltage.
Ease of use
This reflects control-panel layout, including the clarity of its markings, as well as how easy and intuitive the controls were to operate.
Airflow left
This shows how well the louvers can direct air to the left of the unit when the user is facing it. Most important if the air conditioner must be installed in the corner of a room.
Airflow right
This shows how well the louvers can direct air to the right of the unit when the user is facing it. Most important if the air conditioner must be installed in the corner of a room.

Ratings & recommended air conditioners

Air conditioners (43)

Fine cooling performance is a given. Top-scoring models are also energy efficient and relatively quiet. Remember that the more off-center your window, the more an air conditioner's air direction matters. Check the Airflow left and Airflow right columns in the Ratings for this information.
