How do I calculate what size air conditioner I need?

Things to consider before choosing an AC size for a 1200 sq ft home:

There are some regions where the heat is very high during the summer and there are some regions where the heat is not that much compared to others.

If you live in a warmer region, it is best to purchase the highest recommended cooling capacity AC. On the other hand, you can purchase a lower BTU AC if you live in a comparatively lower warm region.

The number of people:

The number of people in your home is another matter you need to keep in mind while choosing the size of the AC. You may find the AC’s size by multiplying the home’s length and width and then multiplying it again with 20 or 25. 

But the number of people increases the BTU requirement up to 600 per person. So, it would be best if you had a clear idea about how many people will be in your home.

Access to sunlight:

Direct access to sunlight is another fact that needs to be considered when choosing the AC size for your 1200 sq ft home. If your room is very sunny, the required BTU increases around 10 – 15 percent. The opposite also happens if the room is dark.
