Ensuring your home is a comfortable oasis during the sweltering days of a summer heatwave is not just a luxury, but a necessity. Discovering the perfect thermostat settings can make a significant difference in creating a cool indoor environment, providing you with the relief and peace of mind you deserve.

That leads to a common question: What is the ideal thermostat setting during the hottest days? In today's blog, you'll discover best practices for your home thermostat to:

  • Save Energy
  • Reduce Costs
  • Maintain Comfort

Best Energy-Efficient Setting for AC Units

The U.S. Department of Energy recommends using a programmable thermostat to efficiently manage your home's temperature. The U.S. Environmental Protection Agency's (EPA) Energy Star program suggests starting your air conditioning (AC) temperature at 78°F, increasing that value by 7°F for unoccupied homes and by only 4°F while occupants are home or asleep.

While the EPA recommends a maximum indoor temperature of 78°F during summer, it also advises adjusting this to strike a balance between energy savings and personal comfort. For instance, if you prefer a cooler 68°F indoors, set your thermostat to 75°F when you're away and 72°F when you're sleeping, ensuring both comfort and energy efficiency.

How to Save on Energy During a Summertime Heatwave

Saving energy during a heatwave involves more than just adjusting your thermostat. Here are some additional tips:

  1. Use Ceiling Fans: Fans can make a room feel several degrees cooler, allowing you to raise the thermostat without sacrificing comfort. Ensure your ceiling fan rotates counterclockwise to push cool air down.
  2. Close Blinds and Curtains: Keep sunlight out during the hottest part of the day to reduce the heat entering your home.
  3. Seal Leaks: Check and seal any leaks around windows and doors to keep cool and hot air inside.
  4. Limit Heat-Producing Activities: Avoid using ovens, stoves, and dryers during peak heat. Instead, use microwaves, outdoor grills, or slow cookers.
  5. Maintain Your AC Unit: To keep your AC system running efficiently, regularly clean or replace air filters, and schedule professional maintenance​​.

Are There Benefits To Setting the Thermostat Lower at Night vs. Daytime?

Lowering your thermostat at night can bring several benefits. It can make it easier to sleep in a cooler environment, and your air conditioner may not have to work as hard to maintain a lower temperature since outdoor temperatures often drop at night. Setting your thermostat to around 72°F at night can improve sleep quality without significantly increasing utility bills, especially if daytime temperatures are higher on a thermostat.

Practical Tips for Optimal Thermostat Use

In optimizing your home's thermostat settings, follow these quick tips:

  • Programmable Thermostats: Investing in a programmable thermostat to automatically adjust temperatures based on when you leave and return home.
  • Zoned Cooling: If possible, use zoned cooling to cool only the rooms you use most frequently.
  • Regular Monitoring: Monitor your energy usage and adjust settings as needed.
