Summer is here, and so is the heat! Your air conditioning will undoubtedly be put to use full force this season. As a result, with prices continually rising everywhere, it is beneficial to know you can cut back and save a few extra cents where you can. Luckily, your Washington Court House Heating & Cooling professionals can direct you where your summer energy usage is concerned. Finding the most energy-efficient temperature setting for your AC that is comfortable while still having the ability to maintain your energy consumption and keep it under control is essential and will ultimately lead to maximized energy savings! 


First of all, let’s talk about energy efficiency before discussing the ideal AC temperature. Energy efficiency means achieving comfort using the least energy possible. By implementing energy-efficient practices (like using an energy-efficient AC temp this summer), we can reduce our carbon footprint and save money on energy bills – a benefit all around. 

During summer months, it’s recommended by The U.S. Department of Energy to set your thermostat to 78°F (25.5°C). We understand that this may seem high, and while this may be true, it’s crucial to understand that there is no one magic number that will work for everyone, everywhere. Just use this as a starting point to find your ideal energy-efficient temperature.  


To find your ideal temperature, you’ll need to experiment a bit. You can start with the recommended 78°F and adjust from there. Try setting your thermostat to this temperature for a few hours to see if it’s comfortable for everyone in your home. Then after several hours have passed, you can adjust the thermostat higher or lower based on your household’s comfort and needs. However, when you make adjustments to your thermostat, try to keep the adjustments in one-degree increments (2 at the most.) Gradually, performing this process will give your AC ample time to regulate the newly set temperature as well as sufficient time to allow everyone in your household to acclimate to said temperature changes. You may be pleasantly surprised to find that when you slowly allow yourself to adjust to one temperature, it will usually turn out to be much more comfortable than you imagined. 


  • It’s best to keep your blinds or curtains closed during the hottest parts of the day to prevent heat from sunlight. 
  • One way to reduce the amount of heat that enters through windows is by using energy-efficient window coverings or reflective films. This small change can have a significant impact on the temperature within your home. 
  • To avoid losing cool air and allowing hot air in, make sure to seal any air leaks around your windows, doors, and ductwork. 
  • To reduce the burden on your cooling system, you should refrain from using appliances that generate heat when the demand is high. 
  • If you don’t already have one, it would be beneficial for you to use a smart thermostat. It can learn your habits and adjust the temperature accordingly. 

To maintain a comfortable temperature in your home during summer while being energy conscious, finding the sweet spot where your personal comfort and sustainability needs meet is the key.
