When choosing a new unit for your AC replacement, there are different sizes to consider. So, how can you choose the right size for your home? This is one of the most common questions homeowners ask. Of course, there is a reason for this. It’s extremely crucial to choose the right size of AC.  

How do you know if your AC is the correct size? Should you consider the windows or square footage of your house? How many BTUs do you need?  

Today, we’re going to share with you several things you should know about selecting the right size for your AC replacement Tempe project. 

What is a BTU? 

If you’re an average homeowner, chances are you don’t know what BTU means and how they work. Because of this, it’s vital to take a look at it first.  

So, what is a BTU? Perhaps you have seen the number of BTUs on your AC before. You are probably wondering what it meant.  

For those who don’t know, BTU is short for British Thermal Unit. It is simply a unit for how much energy your AC requires to cool or heat your home by 1°F in 1 hour.  

Therefore, if your AC unit has 11,500 BTUs, it means that the unit can heat or cool 11,500 BTUs worth of space in a single hour.  

Because of this, you need to consider how many BTUs your unit needs to have when considering what size of AC you require for your property.  

How Big Is Your Property? 

Now that you know what a BTU is and how it works, the next thing you should know is how the square footage of your property affects the required BTU of your AC unit.  

First of all, you’ve got to determine the square feet of space in your property. With this, you can figure out how many BTUs are required every hour so that the unit can properly heat up or cool down your home.  

Thus, if you’ve got a big area, you will require more energy. On average, you will need around 20 BTUs per square foot of space. For example, you will need around 24,000 BTUs for your AC unit if your house has a 1,200 square-footage.  

Other Things to Consider 

Aside from the size of your home, there are other things you have to consider as well. This includes the number of windows in your house and whether or not you have a high ceiling.  

If your home has particularly tall ceilings, then you have to consider this factor when selecting an AC unit. Keep in mind that taller ceilings need more BTUs each hour. The reason for this is that the higher your ceiling, the more heat gets trapped on it. This trapped heat has to be cooled down so that it does not affect the temperature of the rest of your house.  

Another thing to consider is the windows of your home. If your house is old and has large windows, make sure you consider this as well when choosing an AC unit
