Most of us love to keep ourselves sunny and warm here in Mississauga, but it’s obvious that summertime is scorching. During these increasing temperatures, comfort and relaxation are vital. You may enjoy the warm feeling of a sunny day, but you may not want to heat up your house the entire time. So, what is the best AC temperature for summer?

An air conditioner is an excellent modern technology that enables you to enjoy the perks of warm temperatures without dealing with indoor overheating. It can help you relax, sleep better, and be more efficient in everything you do.

Save money and stay eco-friendly by knowing the right AC temperature. Let’s dive deeper into the suitable thermostat settings for summer.

Best AC Temperature Setting for Summer

The U.S. Department of Energy (DOE) recommends setting your home’s thermostat to 78 degrees Fahrenheit throughout the summer. It may appear excessive or even unpleasant to some people. Still, it’s based on several variables that work to minimize the energy consumption and environmental effect of summer AC conditioning.

No matter the temperature on your thermostat, your HVAC system will still be working. By considering the outside temperature, your air conditioner lowers the temperature inside. It’s preferable to set your thermostat higher to enable your AC system to achieve this balance effectively.

It’s important to remember that everyone has different preferences regarding temperature. If you find that 78 degrees are too warm for your liking, feel free to lower the temperature to whatever makes you comfortable. The same goes for those who prefer their homes on the cooler side. If 80 degrees is too chilly for you, raise the temp until you find the perfect balance.

Best AC Setting When You’re Away

Consider a few things to consider when setting up your AC before you leave for vacation. First, think about how long you’ll be gone. If you’re only going to be gone for a few hours, there’s no need to turn off your AC completely. Just raise the temperature a few degrees. It will help save energy without making your home uncomfortable when you return.

If you’re going to be gone for a day or two, it’s best to turn off your AC entirely. It will help prevent your unit from working overtime and raising a high energy bill. Just be sure to open a few windows before leaving so your home doesn’t get too stuffy while you’re away.

For extended vacations, it’s best to keep your AC on but set it to a higher temperature than usual—around 78 degrees is ideal. It will help prevent your unit from overworking and keep your home comfortable when you return.

Best AC Setting for Sleeping

How Temperature Affects Sleep

There are a few reasons why a cooler room is better for sleeping. First, your body temperature naturally dips at night, so a cool room can help mimic that natural dip and make it easier for you to fall asleep. Additionally, a cooler room will prevent you from overheating at night, leading to restless sleep.

What if My Room is Too Cold?

Of course, if your room is too cold, that can also impact your sleep. You may wake up in the middle of the night feeling chilly and unable to fall back asleep. If this happens, add an extra blanket to your bed to stay warm without cranking up the heat and making your entire house uncomfortable.


The best AC temperature for summer is 78 degrees Fahrenheit. However, everyone has different preferences, so feel free to adjust the temperature to whatever is most comfortable for you. Just be sure to open a few windows if you’re going to be gone for an extended period so your home doesn’t get too stuffy. And if you find yourself getting too cold at night, add an extra blanket to your bed.
