There are two main functions of an air conditioner – keeping the indoor air cool and reducing the humidity levels in the room. Now, when it comes to buying an air conditioner, there is a common myth that you should always invest in a bigger size AC as this is the only way to get the fastest and most effective cooling. To some extent, this assumption holds the ground as a powerful AC means faster and more sustainable cooling. But, this doesn’t guarantee the required comfort for humans.
