Features

All the air conditioners in our Ratings do an excellent job of cooling. They also have such convenient features as digital displays, built-in timers, and remote controls. Some units have touchpad controls, and a few change the direction of the airflow automatically to better disperse cool air throughout the room. Look for air conditioner features that affect performance and efficiency.

Ability to detect airflow

Air conditioners generally have louvers you can adjust to direct airflow vertically or horizontally. But most are better at directing air toward one side or the other. Consider your room layout, and look for a model that can direct the airflow where you need it.

Controls

We prefer touchpads with large LED displays, large and uncrowded buttons, clear labeling, and digital temperature readouts. Poorly designed controls are a constant annoyance. Raised buttons with different shapes let you identify functions by feel. And digital temperature readouts provide a more precise reading than the traditional "warmer" and "cooler" settings.

Efficiency aids

An air conditioner with a timer can be turned off when you're out and set to turn on just before you expect to get home. An energy-saver setting stops the fan when the compressor is off. These features save energy.

Dehumidifying mode

A few models can dehumidify without cooling. This feature is useful on humid but cool days in spring and fall.

Fresh-air intake or exhaust setting

It provides ventilation without cooling.
