High is usually most effective for cooling during normal warm weather. However, when it’s very humid, it’s better to keep the fan on low. This cools most effectively because it circulates the humid air slowly and steadily through the air conditioner, allowing it to dehumidify the air more efficiently.
Is central air worth the money?
To be fair, you can choose to only turn on the window units in certain rooms instead of cooling the whole house, but on a square-footage-cooled basis, central air is the more efficient option. The largest portion of the average homeowner’s electricity cost is for cooling, so this is certainly worth considering.
