If you have an older air conditioner, you're more likely to end up with an eye-popping electric bill. Modern technology, however, has made significant strides to make the most efficient air conditioners more eco-friendly and economical.

To avoid wasting unnecessary electricity, look for Energy Star-certified air conditioners, that meet strict guidelines enforced by the U.S. Environmental Protection Agency or U.S. Department of Energy, making them among the most efficient.

Other features to look for include digital thermostats, which turn your unit on and off once your desired temperature has been reached, as well as 24-hour timers that power your device down automatically, sleep modes, and Wi-Fi connectivity to control the air conditioner from afar.

The Windmill AC — $395.00

This sleek window air conditioner looks as good as it cools while keeping money in your wallet. Rather than blowing air out from the center of the device, it blows up from the top, circulating air around the room to maximize efficiency. While most air conditioners only cool the air, Windmill’s also doubles as an air purifier, so you can save on powering a second, separate device all together. Instead, Windmill’s eco-friendly design features two filters: one that filters dust through a washable antimicrobial filter, and another disposable one that uses activated carbon to eliminate harmful pollution, like smoke and VOCs.

It’s Energy Star certified, maximizing your savings up to 35 percent, and nine times quieter than other models thanks to its U-shape, which puts the noisiest part of the machine on the other side of the glass.
