What Temperature Should I Keep My AC in the Summer or Winter

There are so many factors to consider when it comes to the best temperature for your AC unit, but the most important thing is that you keep your home at a comfortable level of humidity. You want to make sure that this doesn’t result in too much water vapor being produced by your AC unit or cause it to work harder than what it should. You want it to work efficiently so that it doesn’t get too weak and break down.

In this article , you will learn the ideal temperature for your AC unit in both summer and winter. You will also learn about how to make sure that it is running at top efficiency.

The Temperature to Keep Your AC Unit in Summer

The temperature to keep your AC unit depends on the weather and the season. In the summer, the ideal temperature to ensure you’re not overcooling your home is typically between is 78 degrees Fahrenheit, according to the Department of Energy. If you are keeping it at this temperature, it is going to be a comfortable experience for your loved ones when they return from their activities during the day and you’ll save a bit of money on your electric bill each month.

If you are using the AC unit to blast some nice cool air in the summer or want to save on energy bills, then this is probably ideal for you. As experts say, if you’re not cooling your home down enough during the summer, then it will cost you more money. And if it’s too hot for your liking and your AC unit is running harder than what it should be when temperatures are relatively low and nights are pleasant, then this will also cost you more money in energy bills.

The Temperature to Keep Your AC Unit in Winter

In the winter, you want to keep your home about 10 degrees warmer than what is comfortable for your family in order to make sure it remains at an optimal level of humidity. The best temperature for the winter is typically 68 degrees Fahrenheit, but this will vary when you have large people in your household or younger children.

You also want to keep your thermostat set to the same temperature when you are asleep. This will ensure that you aren’t overcooling your home while everyone is sleeping and that it isn’t doing a lot of work while no one is using it. It will also help you save money on your energy bill each month, especially if the AC unit is cooling off a good portion of your home.


When you are changing the temperature on your thermostat, make sure to be careful. If you set it too high, you could have water vapor seeping into your ducts and leaving mildew streaks on the walls of your AC unit. This could cause damage to the unit over time and it will also leave a smell in your home that will be quite unpleasant for everyone in the family.

Additionally, you want to make sure that you don’t set your AC unit to a temperature that is too high or too low. You can see this by measuring the temperature of your house at different times throughout the year. If it is staying within a certain range, you are likely doing fine. If there are large swings in between those temperatures for a few days at a time, the AC unit may not be working as effectively as it should, and it could end up costing you more money than it should over time.

By making sure that the temperature of your AC unit is within a reasonable range in highs and lows, you will ensure that it is working as efficiently as possible to keep your family comfortable. You will also save money in the long run and ensure that it stays clean without any lingering mildew or mold inside of it.


So, the best temperature for your AC unit is typically between 68 and 78 degrees Fahrenheit, but you’ll want to alter this if you have a large home or are keeping it at a consistent level for people who are of different ages.

If you do have a lot of people in your home, it is going to be important to note that the temperature should be kept within 10 degrees of what is comfortable for them in both summer and winter. If you notice that the temperature is behaving erratically, then it might be time to call an AC repairman to see if they can see any problems with your unit or point out where there could be a leak in an area.
