It’s summer, and you’re going through a nasty heatwave. You have already invested in eco-friendly air conditioning, but there’s one more thing: what is the best AC temperature for energy saving?
Maintaining a comfortable indoor temperature is essential for every homeowner. The air conditioning system plays a vital role in keeping your home cool and comfortable, but finding the best temperature can be challenging. In this post, we look at the ideal temperature to set your air conditioning unit at.
The Best AC Temperature for Energy Saving

The ideal temperature for your air conditioning unit is between 72 and 78 degrees Fahrenheit (22 to 25.5 degrees Celsuis). This temperature range is comfortable for most people, and it also helps to save energy and reduce your utility bills.
Why is This Temperature Range Ideal?
Maintaining a temperature between 72 and 78 degrees Fahrenheit (22 to 25.5 degrees Celsuis) is the most energy-efficient way to cool your home. When the temperature is set any lower, your air conditioner has to work harder to cool your home, resulting in increased energy consumption and higher electricity bills. And for every degree of temperature increase, your AC uses 5% less energy to operate (and can show up as a 3% reduction in your bill). So, the higher your AC temperature setting, the lower the energy usage – and that means lower utility bills.
Additionally, setting the temperature below 72 degrees can lead to overcooling, which can cause discomfort, health issues, and an increased risk of developing respiratory problems.
On the other hand, setting the temperature too high can lead to heat exhaustion, dehydration, and other heat-related illnesses.
Ideal Nighttime Sleep Temperature
The ideal temperature for sleep is approximately 65 degrees Fahrenheit (18.3 degrees Celsius), according to doctors. This may vary by a few degrees from person to person, and you should do what suits you, but most doctors recommend keeping the thermostat set thereabouts.
How to Set Your Air Conditioning Temperature

To set your air conditioning temperature, start by setting the temperature to 78 degrees Fahrenheit. If you’re still feeling warm, you can gradually lower the temperature until you find the sweet spot between comfort and energy efficiency.
If you have a programmable thermostat, you can set it to automatically adjust the temperature during the day and night. This can help you save energy and reduce your utility bills while still maintaining a comfortable indoor temperature.
Tips for Increasing Comfort and Energy Efficiency

In addition to setting the temperature to the ideal range, there are other ways to maximize energy efficiency in your home:
- Use energy saving fans to circulate air and reduce the workload on your air conditioner
- Keep your curtains and blinds closed during the hottest part of the day to block out the sun’s heat
- Replace your air filter regularly to ensure optimal airflow and energy efficiency
- Schedule regular maintenance for your air conditioning unit to keep it running efficiently and prevent costly breakdowns

As for the ideal temperature, we recommend setting your thermostat to 78 degrees in the summer when you’re at home and to at least 80 degrees if your home is vacant for more than a few hours.
Many homeowners completely turn off their units while being away from home. However, the best solution is to turn the air conditioning up a few degrees but not completely off.
Do you mean being away from home for work (during the day)? Or being away for longer periods (like a vacation or trip)? Wouldn’t leaving the unit on use up a lot of unnecessary energy?
