Three extra cool air conditioning units to keep you comfortable

Stay chill.

Since ancient times, humans have been using technology to lower air temperatures during hot seasons. In Egypt, they would hang wet pieces of cloth to evaporate and cool off the air, and wealthy people in the Roman Empire circulate cold water in indoor pipes. Thanks to an American engineer Willis Carrier, the first modern air conditioner came onto the scene in 1902. Now more than 100 years later, AC options are aplenty. When combined with more eco-friendly practices, our favorite air conditioners are extra effective—and won’t obliterate your energy bill.

This LG air conditioner can be set on a timer with a smart outlet, and works well with smaller windows and rooms.

It also features an energy-saving mode and remote control with a digital thermostat.
