With nearly 90% of households in the U.S. owning some form of air conditioning, according to the Energy Information Administration (EIA) in 2020, air conditioning has undeniably become a necessity.

With air conditioners becoming more widespread and often used daily, one common question arises: What is the best temperature setting? While this might seem straightforward, the answer depends on various factors, including personal preference and environmental conditions.

Let's explore the best air conditioner temperatures for various situations.

Best Temperature For Air Conditioner In Summer

The average temperature people set their thermostats to ranges between 68° and 78° Fahrenheit, though this can vary based on individual preferences.

For maximum energy efficiency during the summer, it is advisable to set your air conditioner’s thermostat as high as comfortably possible.

According to energy.gov, the smaller the difference between indoor and outdoor temperatures, the lower your overall cooling bill will be.

For an energy-efficient option, 78° Fahrenheit is ideal as it balances comfort and energy savings. When you're away from home, it's recommended to set the thermostat higher, around 85°F (29°C), or turn it off entirely to conserve energy.

Best Temperature For Air Conditioner In Hawaii

Similar to summer, Hawaii's tropical climate presents unique challenges for maintaining indoor comfort.

The best air conditioner temperature in Hawaii can vary, but a good rule of thumb is to keep it set around 74-78°F (25°C) when at home.

Air conditioners are also great for dehumidifying, which is beneficial in Hawaii’s tropical climate and high humidity.

Best Air Conditioner Temperature For Sleeping

A good night's sleep is crucial, and the temperature of your sleeping environment plays a significant role in the quality of your rest.

With the sun gone, it’s easier and more energy-efficient to hold a lower temperature, especially in homes that aren’t energy-efficient, like those with jalousie windows or single walls.

The National Sleep Foundation suggests setting your air conditioner between 60°F (16°C) and 67°F (19°C) for optimal sleep.

This cooler temperature helps your body cool down, leading to better sleep quality. However, this can vary from person to person.

Those accustomed to warmer climates year-round may prefer something warmer, around 70-76°F, especially considering that bedding is likely lighter in a warmer climate.

Best Temperature For Newborns

Creating a comfortable environment for newborns is crucial. According to Pampers, babies sleep better and longer at a temperature of 68-72°F.

Maintaining this temperature helps reduce the risk of overheating and SIDS.

Best Air Conditioner Setting

Finding the ideal setting for your air conditioner depends on several factors, including your comfort level, energy costs, and the specific climate of your area.

While this may vary by model, some options have energy-efficient features, such as mini-splits with inverter technology, that offer an ‘auto mode.’ This auto mode allows the air conditioner to automatically adjust the temperature and fan speed to maintain a comfortable room temperature.

Another useful feature is a timer, which can be great for when the sun goes down and the night gets cooler. Lowering the temperature may be necessary for better rest, or you can turn it off to save energy and utilize the cool night wind.

Best AC Temperature For Energy Saving

Energy efficiency is a major consideration for many homeowners. The U.S. Department of Energy recommends setting your thermostat to 78°F (25°C) when you're at home and raising it to around 85°F (29°C) when you're away.

Using a programmable thermostat can help automate these settings, ensuring you save energy without sacrificing comfort.

What Temperature Is Too Cold?

Setting your air conditioner too cold can lead to discomfort and increased energy bills. Typically, anything below 68°F (20°C) is considered too cold for most people.

Not only can this cause a spike in your electricity costs, but it can also lead to health issues such as respiratory problems.

Conclusion

Finding the best air conditioner temperature setting is a balance between comfort, energy efficiency, and individual preferences.

By following these guidelines, you can ensure that your home remains comfortable while also being mindful of energy consumption and costs.

Whether you're trying to beat the summer heat, get a good night's sleep, or save on your energy bill, adjusting your air conditioner to the right temperature can make a significant difference.
