How to Find the Best AC Temperature Setting for Comfort and Savings

When that summer sun is blazing, and the air is thick with humidity, we all want to retreat to a cool, comfortable haven. You’ve probably heard the Department of Energy’s suggestion for the best AC temperature setting: a breezy 78 degrees Fahrenheit. While it’s great advice for saving money on those electricity bills, we’re going to explore why a personalized approach is key to finding the best AC temperature for your needs. Let’s explore how to find that balance between energy efficiency, budget, and that blissful sigh of relief when you step inside.

Decoding theMagicNumber: 78 Degrees Fahrenheit

It’s plastered everywhere – from energy-saving websites to pamphlets handed out at your local utility company. So what makes 78 degrees so magical? According to the U.S. Department of Energy, this setting strikes a balance between comfort and energy efficiency.

However, this temperature can feel a bit warm for some. This is especially true for those who are more sensitive to heat, have specific health conditions, or live in particularly humid regions. A Consumer Reports survey actually found that people with central AC systems typically set their thermostats to a median temperature of 71 degrees Fahrenheit.

Why It Works, Why It Might Not

The rationale behind the 78-degree recommendation lies in the temperature differential between the outdoors and indoors. The smaller the gap, the less your AC system has to strain. This, in turn, leads to less energy consumed and lower energy bills.

However, comfort plays a huge role in your home environment. It can affect sleep quality, productivity, and overall mood. The potential energy savings might not feel worth it if you’re constantly uncomfortable.

Discovering Your Own Best AC Temperature Setting

Remember, the 78-degree benchmark serves as a good starting point. It’s meant to encourage energy conservation, not dictate a strict standard.

Finding the perfect balance can be challenging. Years in the HVAC business have shown me everything – from folks setting their AC to a bone-chilling 65 degrees, only to complain about high bills, to those sweating it out at 85 degrees in an attempt to be energy saints. The best AC temperature setting truly boils down to what works best for your household, factoring in lifestyle, budget, and personal preferences.

Customizing Your Comfort Zone

To figure out your sweet spot, begin with experimenting. Gradually increase your thermostat setting from your usual preference and observe how you feel. Pay attention to high humidity levels, especially in areas like bathrooms and basements. Lastly, look out for signs of excessive humidity such as condensation or a stuffy, musty smell. Investing in a tower fan can also help with air circulation.

Steps to Tailor Your Best AC Temperature Setting:

  1. Begin at 78 Degrees: This is the Department of Energy’s recommended starting point when looking for the best AC temperature setting that also offers savings.
  2. Fine-tune Your Comfort Level: Gradually decrease the setting by 1 or 2 degrees at a time. Pause at each adjustment and evaluate your comfort level. Keep adjusting until you feel consistently cool and relaxed.
  3. Factor in Individual Needs: Take note of special considerations, such as infants needing warmer temperatures for restful sleep or small children needing the temperature set lower.
  4. Monitor Energy Costs: Keep an eye on your bills and usage for a few weeks to gauge the impact of each setting to find the temperature that balances comfort and affordability. This balance point will be your household’s best AC temperature setting.

Maximizing Comfort and Efficiency

As you zero in on your ideal temperature, explore strategies to enhance both comfort and efficiency. These will optimize the benefits of the best AC temperature setting for your needs:

Programmable or Smart Thermostats

Programmable and smart thermostats are your secret weapons in achieving the best AC temperature setting at the right time. They automatically adjust temperatures based on preset schedules. This lets you set a higher temperature at work and automatically lower the temperature before you return home. This will reduce your cooling costs while keeping your home comfortable.

Supplementing With Fans

Ceiling fans are great for better air circulation. When paired with your best AC temperature setting, they create a wonderful breeze. Remember to rotate those blades counterclockwise in the summer to push cool air downward for a cool sensation.

Home Improvement Tactics

Even simple improvements can make a big difference. Consider adding room-darkening shades to block out direct sunlight. Also, make sure weather stripping is in good shape around windows and doors to prevent leaks.

Strategically planted trees can shade your home and lower the temperature surrounding your HVAC unit for even better AC performance. All these ideas work in tandem with the AC temperature setting you’ve chosen, boosting your comfort levels without sending energy costs sky-high.

Taming Those Energy Bills

Consider these tips if you want to beat the heat without breaking the bank. Implementing even a few of these alongside the optimal AC temperature setting will add considerable savings over time. This helps optimize not just your personal comfort, but your energy expenditure.

Is Turning the AC Off a Smart Move?

It seems logical – why keep the AC humming away when you’re not home? Although tempting, constantly cycling your system on and off might actually use more energy than leaving it at a slightly higher setting while you’re out. It’s far more energy-efficient to let the AC work at maintaining a stable temperature than to cool down an overly warmed-up space continuously.

Additional Cost-Saving Tips:

  • Close Blinds During the Day: Prevent the sun from turning your home into an oven by closing curtains and blinds when it’s hot outside.
  • Embrace Nighttime Cooling: When evening temperatures are mild, shut down the AC. Open windows and allow a gentle breeze to naturally cool your home overnight. Seal everything up in the morning to trap that refreshing coolness.
  • Limit Heat-Producing Appliances: Delay those oven-baked feasts, clothes-drying sessions, and even excessive use of hair dryers for cooler parts of the day or after sundown. Appliances generate a lot of heat in homes.
  • Remember the Filter: Remember to change or clean those air filters regularly. A dirty air filter hinders proper airflow and unnecessarily makes your AC unit struggle. It’s a simple chore that reaps significant rewards when coupled with an optimal AC temperature setting in your home.

Understanding Your AC’s Workload: EPA Data Unveiled.

Take a look at the chart below, which is created from data published by the EPA on climate change indicators. This illustrates a noticeable increase in the demand for cooling due to our changing climate. Hotter summers that demand longer AC run times and, naturally, higher electricity consumption is a trend I’ve witnessed firsthand in the industry. Make sure your refrigerant levels are good and keep up on your AC maintenance. Minor issues can turn into major problems that can end up with you needing to replace your air conditioner if they are not dealt with promptly.

Don’t panic, though. By staying informed and finding your home’s best AC temperature setting, you can easily achieve comfortable summers and keep those energy bills under control. Using things like a programmable thermostat can make a difference in monthly energy bills.

FAQs about best AC temperature setting

Is 72 a good temperature for air conditioning?

While many people find 72 degrees to be a very comfortable room temperature, remember that setting your thermostat higher can save you money on energy costs. Finding the right degree set involves considering both personal preference and efficiency. If 72 feels great and doesn’t spike your bills too high, you’ve found your ideal balance.

What is the most efficient temperature to set the AC?

The most efficient temperature setting is typically the warmest you find comfortable. However, a generally accepted energy-efficient benchmark is 78 degrees Fahrenheit, recommended by the U.S. Department of Energy. Keep in mind that this can be tailored based on individual preferences. You can save energy and reduce heat by setting your air conditioner a few degrees higher and taking the steps outlined above.

What should I set my AC to in summer?

Aim to start with 78 degrees Fahrenheit. This strikes a balance between comfort and efficiency. Consider adjusting up or down in small increments to find a sweet spot based on your individual comfort level, local climate, and energy budget.

Is 78 too hot for a house?

While 78 degrees Fahrenheit is an energy-saving recommendation, many people find it to be too warm. There’s no need to force yourself to stick to it if it causes discomfort. Remember, the best AC temperature setting prioritizes YOUR comfort alongside energy efficiency. The beauty of it all is that finding this balance depends on YOU. Adjust your thermostat in small increments to find a temperature that feels just right for you and your family while being mindful of energy usage and summer energy savings.


There’s no perfect formula in the quest for the best AC temperature setting. It’s not about blind adherence to the latest advice but about listening to your home and to yourself. The best AC temperature setting combines comfort and energy consciousness without compromises.
