Learn about the factors beyond square footage that you'll need to consider.

Most brands will tell you to calculate the BTU you need based on the square footage of the room you&apos;re trying to cool. While that&apos;s not incorrect, there are some other factors to consider, too. The ceiling height, the amount of sunlight the room gets, and how many people are regularly in the space will all have an impact on the size requirement.&#xA0;We have a handy <a href="https://july.ac/blogs/resourcecenter/what-size-window-ac-do-i-need">2-minute quiz</a> that will help you figure out which size of July you need.Still not sure? That&apos;s why we&apos;re here. Email us at <a href="mailto:support@july.ac">support@july.ac</a> with a picture of your space and we&apos;ll help you determine the right size for your space.&#xA0;

How do I know which BTU size I need?

You're often going to hear the term "BTU" when figuring out which A/C is right for you. Find out what that means.

You&apos;re often going to hear the term &quot;BTU&quot; when figuring out which A/C is right for you. BTU, or &quot;British thermal units,&quot; are a measure of cooling power. Depending on the size of your space (and some other factors), you&apos;ll need a certain amount of BTU power to effectively cool the room.&#xA0;As a general rule, one square foot of space needs about 23-24 BTU to cool it effectively. This can vary though, depending on other factors present in your space. We&apos;ve got a handy quiz that can help you identify which BTU size you&apos;ll need for your space: <a href="https://july.ac/blogs/resourcecenter/what-size-window-ac-do-i-need">just click here</a>.Our Small July (6000 BTU) can cool rooms up to 250 sq. ft. large, and the Medium July (8000 BTU) can cool rooms up to 350 sq. ft. large.
