As the summer heat intensifies, the question of what temperature to set your air conditioner (AC) at becomes increasingly relevant. Striking the right balance between comfort and efficiency can be challenging, but it’s crucial for both your well-being and your energy bills. In this blog post, we’ll delve into the ideal AC settings for the summer months, specifically tailored for residents in Orlando, Boca Raton, and Port St. Lucie. The Right Service HVAC, your trusted partner in home comfort solutions, is here to guide you through optimizing your AC settings.

Understanding the Importance of the Right Setting

Setting your AC at an optimal temperature is vital for several reasons. Firstly, it ensures your home remains a comfortable refuge from the sweltering heat outside. Secondly, it plays a significant role in managing your energy consumption, which directly impacts your utility bills. Lastly, the right settings can extend the lifespan of your AC unit by preventing excessive wear and tear.

What Temperature To Set Air Conditioner In Summer

The U.S. Department of Energy recommends setting your thermostat to 78°F (26°C) when you’re at home and awake. However, preferences can vary based on individual comfort levels and the specific climate of your area. Here’s a detailed table to help you understand the optimal temperature settings for different summer scenarios:

Situation Recommended Temperature Reasons
Home and awake 78°F (26°C) Balances comfort and energy efficiency
Away from home 85°F (29°C) Saves energy without letting the house get too hot
Sleeping 82°F (28°C) Warmer temperatures are conducive to sleep, according to some studies
High humidity conditions 76°F (24°C) Lower temperatures can help remove moisture from the air, improving comfort

Remember, these are starting points. You should adjust these settings based on your personal comfort and the specific needs of your household.


How can I save energy without sacrificing comfort?

Invest in a programmable thermostat. It allows you to set your AC to automatically adjust the temperature based on the time of day. For instance, you can set it to start cooling your home just before you return from work. Additionally, consider using fans to circulate air, which can make a room feel cooler without lowering the thermostat.

Is it better to keep the AC on all day or turn it off when I’m not home?

It’s more energy-efficient to increase the temperature rather than turning off the AC completely when you’re not home. This prevents your home from becoming excessively hot, which would require your AC to work harder and consume more energy to cool down later.

How does outdoor temperature affect my AC settings?

On extremely hot days, your AC might struggle to maintain a large difference between the outdoor and indoor temperatures. On such days, setting your thermostat a few degrees higher can ease the burden on your AC and prevent excessive wear.

How does humidity affect AC settings?

High humidity can make the air feel warmer than it actually is. Using a dehumidifier or an AC with humidity control can make higher temperatures feel more comfortable, allowing you to set your AC at a more energy-efficient level.


Navigating the complexities of setting your AC in the summer doesn’t have to be a daunting task. By understanding and implementing the recommended temperature settings, you can enjoy a comfortable home environment while keeping your energy bills in check.
