What Temperature Should I Set My Air Conditioner in the Summer?

Hand setting the thermostat temperature to 66 degrees Fahrenheit in the summer.

When the summer months roll around, every minute at home is spent fighting over the thermostat. Finding the perfect indoor temperature for everyone to enjoy is a herculan task for every head of the household — but outside of comfort, you also have to consider how your energy bills will be affected. 

So, at what temperature should you set the air conditioner in the summer? The truth is that there is no one-size-fits-all solution. Everyone has their own preferences. However, the Department of Energy does offer temperature recommendations that can help you save money while staying comfortable.

Let’s dive into what temperature your air conditioner should be set to in the summer while you’re at home, asleep, or away. 

Recommended AC Temperature for the Summer

While performing AC repairs in Alpharetta, GA, contractors often get asked what temperature air conditioners should be set to in the summer. To answer this question, we defer to the experts. 

According to the Department of Energy, 78°F is the ideal temperature for your home during the summer months. This allows your AC unit to maintain the set comfort levels without being overworked.

But if this temperature seems high, you’re not alone! Most people like to keep their homes at a cool 72°F to be comfortable. That being said, the DOE has determined that raising the temperature by just one degree can help you save up to 3% on energy costs. 

If you’re eager to lower your electricity bill, consider raising the thermostat settings and running the ceiling fans counterclockwise to create a downward draft of cool air. 

What’s the Best Temperature for Sleep?

Whether your summer days are spent working or relaxing, keeping your home between 72°F and 78°F might not seem so bad during the day… but the same can’t be said for nighttime. 

Have you ever struggled to fall asleep because your room is too hot? Our bodies associate heat with wakefulness, which is why our core temperatures drop at night to promote good rest. 

A study performed by the National Institute of Health found that 60-67°F is the best temperature for sleeping. Now you know what temperature you should set your air conditioner at in the summer if you want to get a good night’s rest — but keep in mind that this will affect your air conditioner’s energy efficiency as well as your utility bills. 

What Temperature to Set Air Conditioner On While Away

Do you have a programmable thermostat that keeps your home at an ideal temperature while you’re at home, asleep, or at work? It’s time to turn it off!

If you plan on being away for a prolonged period of time — as in, summer vacation — set your thermostat to 85°F and bask in the knowledge that you’re saving tons on energy bills. You can lower the temperature to something more comfortable on your smartphone before the big homecoming if you own a smart thermostat with WiFi capabilities.

This is only recommended if your house is empty. If you’re leaving furry friends behind, make sure the indoor climate is at least 78°F, if not cooler.
