It can range from one pint per hour to as many as Higher-rate units are best for those who live in high-humidity areas. Efficiency: To find out how energy efficient a model is, look at the manufacturer's Energy Efficiency Rating EER , which is the BTU also known as the cooling output divided by the power consumption in watt-hours.
If you're replacing an existing unit, choose an air conditioner with a plug type that matches your old model. Here are some important air conditioner features you'll want to look for in order to save time and energy and improve the quality of your air. Product Reviews. Home Ideas. United States.

The Rise of the Cleanfluencer. Pulse Getty Images. But if you're wondering what to look for when buying an air conditioner this summer, here's what to consider: First, what are the different types of air conditioning units?
There are four main types of air-conditioning units. They are: 1. Do you live in an apartment? You may have to take some extra steps, such as getting permission from your landlord, before you install an AC in your apartment.
Consider Intelligent Cooling Some air conditioners have gotten smarter, allowing you to control and adjust them from your smartphone. You may even be able to interconnect them to other cooling units in your home. Watch the Warranty Some air conditioners have longer warranties than others. The window air conditioners in our tests have cooling capacities ranging from 5, to 12, British thermal units Btu.
To measure your room, multiply the length of the room by the width. Energy Star recommends that you make allowances for other considerations—such as the height of your ceiling, where the unit will be placed, and the size of your windows and doorways.
Almost all the window units we test meet the latest Energy Star standards, which require models to be at least 10 percent more efficient than those without that certification. Standout models have quiet operation and convenient controls, and they work under brownout conditions. Check our air conditioner ratings to see to how models stack up.
Small: Capacity ranges from 5, to 6, Btu, and these units cool roughly to square feet. Medium: Capacity ranges from 7, to 8, Btu, and these models cool roughly to square feet. Prices start creeping up, and their size and weight can make them more difficult to install and remove for winter storage. Large: Capacity ranges from 9, to 12, Btu, and these units cool between and square feet. Portable models are intended for homes in which window configurations or building regulations prevent installation of window units.
The portable air conditioners in our tests range from 9, to 15, Btu. And because all the mechanicals are sitting in the room, they tend to be noisier than window-mounted units. Split ductless is a smart way to add air conditioning to a limited number of rooms without having to open up walls to install ductwork—as you would with a central-air system—or install and remove multiple window units each year.
Split ductless is pricier than window or portable units and professional installation is recommended but less expensive than central air if you are cooling only a few rooms. However, if you are looking to cool the majority of your home, a central air-conditioning system is probably the more cost-effective choice.
All the units in our air-conditioner ratings do an excellent job of cooling. They also come with convenient features, such 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. Touchpads with large LED displays, sizable and uncrowded buttons, clear labeling, and digital temperature readouts are easier to use.
Poorly designed controls are a constant annoyance. Raised buttons with different shapes let you identify functions by feel. Air conditioners have louvers you can adjust to direct airflow vertically or horizontally. Some have fans that oscillate. But most are better at directing air toward one side or the other.
