The 5 Most Popular Window Air Conditioners

With the hottest time of the year right around the corner, many people will be searching for alternative energy efficient ways to keep their home cool. Window air conditioning units are a simple and subtle solution to staying out of the heat—but with so many options in the industry, how can you be sure which product preforms the best AND is better than rest?

This article will guide you through five of the best window air conditioners currently available on the market and help figure out which unit is perfect for your needs.

BTUs & Window Air Conditioning

Before proceeding, it is important to understand what BTUs refer to and why it’s crucial when deciding which window air conditioning unit is best for you.

A common acronym used to measure energy for all types of air conditioners and heaters, BTU officially stands for “British Thermal Units.” One BTU is what it takes to the amount of thermal energy it takes to heat (or cool) one pound of water by one degree. A match is a great example to help put this in perspective. When you light a match, the heat that is produced from it is approximately equal to one BTU.

In regard to window air conditioning, the more British Thermal Units the appliance has, the more powerful it will be at cooling and/or heating the space it is located within.

To help you determine how many BTU’s you will need for the space you want to buy a window air conditioner for, please refer to our Cooling Capacity Calculator.
