When the weather turns warm, you count on your air conditioning to help your house stay cool. But what if you want to buy a new air conditioning unit? One of the hardest things that people find about choosing an AC is to know how many BTUs it should have. If you get one with too few, it will be running all the time. If it has too many, it will be too cold.
A good way to figure out the number of BTUs your AC should have is to go by your home’s square footage. Below is a chart that can help with giving you a general idea about what you should look for based on your house’s square footage. It covers houses in many sizes from tiny to medium.
