Summer can be a fun time to relax and kick back, but when the temperatures and humidity rise, you can find yourself tired and sluggish, sweating in your living room and not feeling up for anything. A good way to cool down is window air conditioners, which effectively cool down a room to comfortable temperatures without the expense and commitment that comes with central air conditioning. Because it requires little to no alteration to the home, it is a great option for renters who want to cool down and they are also kinder to the environment than central air conditioning because they take a lot less energy.
