Stephens Plumbing

July 15, 2023


When summer is in full swing, you don’t want to be stuck struggling with finding the best temperature for your AC. At Stephens Plumbing, we’ve noticed that the simple question, “What is the best temperature for AC?” frequently provides complicated and diverse answers.

We’re going to dig into the answer to that question here so that we can give you some more clarity and guidance. It can be challenging to find a good compromise between comfort and energy efficiency, but that’s why we’re here to help. Let’s look at the best AC temperature for Summer, for sleeping, and for keeping your beautiful home mold-free.

Best AC Temperature for Summer

If you’re wondering what is the best temperature to set the air conditioner in the summer, The suggestion from the US Department of Energy is to set your air conditioning to 78 degrees F during the hours you’re at home, and 7- 10 degrees warmer while you’re away from home. These temperatures are generally recognized as the best compromises between comfort, energy efficiency, and cost-effectiveness.

Best AC Temperature for Sleeping

The importance of sleep just can’t be overstated, and trying to sleep when you’re too hot or too cold can be maddening. The National Sleep Foundation maintains that the best AC temperature for sleeping is between 60 and 67 degrees F, though it’s important to remember that comfort is highly subjective, and fine-tuning temperature is essential to comfortable sleep.

Best AC Temperature to Prevent Mold

Mold prevention is another essential aspect of AC management. Mold thrives in warm, humid conditions, and can pose significant health risks even to healthy individuals. The best AC temperature to prevent mold is going to be between 70 and 78 degrees F, and while that will help, it’s also important to remember to maintain a humidity level below 60%. By lowering the temperature to the mid-70s, and leveraging a dehumidifier to remove water from the air, homeowners stand a much better chance of keeping their homes mold-free.
