Buying an air conditioner is an important purchase, and it is worth your time to make sure you do it right. The table below can be used to get a VERY ROUGH ESTIMATE of how many BTUs you need to cool a given area.
However, since there are many additional factors that influence the precise number of BTUs necessary to effectively and efficiently cool your specific area, we highly recommend that you speak with an expert to ensure the most accurate measurements.
Need a More Precise Measurement?
We're here to help you get the exact product for your needs. If you need a more precise sizing calculation, our experts can give you a complete, professional sizing for your space.
For a fee, you can get the professional sizing worksheet emailed directly to you, or you can speak to an expert directly by calling 866-554-4328. The fee can be applied to your purchase, making this service free to use.
Alternatively, if you're sizing for a single room (or multiple rooms) and want a good estimate without having to fill out our entire worksheet, you can use our online single-room sizing tool to give you a more accurate estimate than just using the table below.
