Summers in the Central Savannah River Area are typically intense. Residents in Augusta, Evans, Grovetown, Martinez, Hephzibah, and Graniteville know what it feels like when temperatures climb into the 90-degree range. During these stretches of extreme heat, one question comes up: What temperature should I keep my thermostat set to during the summer?
Homeowners usually assume there is one perfect temperature setting. The truth is that comfort is highly subjective. Every family has different preferences. Every home has different insulation levels. Every cooling system operates under different conditions.
The goal is not simply to make your house cold. The goal is to create a comfortable indoor environment while helping your air conditioner operate efficiently. After all, according to the U.S. Energy Information Administration, “Air conditioning accounts for about 12% of U.S. home energy expenditures.” The right thermostat setting can help manage energy costs, reduce strain on your system, and maintain indoor comfort even when outdoor temperatures are soaring.
Understanding recommended thermostat settings can help you get the most from your cooling system.
If you search online for summer thermostat settings, you will find a wide range of recommendations. Some sources suggest 72 degrees. Others recommend 78 degrees. The reality is that there is no single setting that works equally well for every household.
Several factors influence comfort, such as:
Some families prefer cooler temperatures. Others are comfortable with slightly warmer indoor conditions. What matters most is finding a setting that keeps your household comfortable without putting stress on your system.
The U.S. Department of Energy recommends higher temperature settings when possible because they can reduce cooling costs. And adjusting thermostat settings appropriately can help improve cooling efficiency and reduce energy consumption. However, comfort should always remain the main consideration, especially during extreme summer heat.
For many homeowners in Augusta, Evans, or anywhere else in Columbia County, a thermostat setting between 72 and 76 degrees provides a good balance between comfort and energy efficiency.
When you are at home, your AC thermostat settings should be at a temperature that feels comfortable while allowing your system to operate efficiently.
For most households, a range between 72 and 76 degrees works well during the summer months.
Many homeowners in Augusta begin with 75 degrees and make small adjustments based on comfort. This approach often provides a good balance between cooling performance and energy usage.
The following factors can influence where your ideal setting falls.
Some people naturally feel warmer than others. Children, older adults, and individuals with certain health conditions may have different comfort needs.
Large windows, vaulted ceilings, and open floor plans can impact indoor temperatures. Homes that receive significant afternoon sun may require slightly different thermostat settings.
Humidity affects how warm a home feels. High humidity can make a house feel uncomfortable even when the thermostat reading appears reasonable. This is particularly important in communities such as Evans, North Augusta, and Belvedere, where summer humidity can be significant.
If your home feels comfortable at 75 degrees, there is little reason to lower the setting further. Consistent comfort should be the primary goal.
If your home never feels comfortable despite adjusting thermostat settings, Bailey's can inspect your cooling system and identify potential issues before they become major malfunctions.
Leaving your thermostat at the same setting all day may not be necessary if the home is empty. Many homeowners can save energy by increasing the temperature slightly when nobody is home.
A common approach is raising the thermostat by two to four degrees during periods of extended absence. For example, if your preferred indoor temperature is 74 degrees, you may choose to set it to 77 or 78 degrees while away.
This strategy allows the air conditioner to run less frequently while still maintaining reasonable indoor conditions. The key is moderation.
Programmable and smart thermostats make this process simple. They can automatically adjust temperatures based on schedules and occupancy patterns. Homeowners throughout Augusta, Graniteville, Hephzibah, and Grovetown use programmable thermostats to improve efficiency without sacrificing comfort.
Your thermostat works best when the rest of the home supports efficient cooling. Some simple habits can improve comfort and help your thermostat and air conditioner perform more effectively.
Sunlight entering through windows can significantly increase indoor temperatures.
Closing blinds, curtains, and shades during peak sunlight hours helps reduce heat gain. This simple step can make a noticeable difference during hot afternoons in Evans and Martinez.
Frequent temperature changes create inconsistent indoor conditions. Choose a reasonable setting and allow the system to maintain it. Constant adjustments rarely improve comfort and may reduce efficiency.
Air filters should typically be inspected every month. Many homes benefit from replacing filters every one to three months. Homes with pets, construction activity, or allergy concerns may require more frequent changes. Dirty filters restrict airflow. Reduced airflow forces the system to work harder. Regular filter replacement remains one of the easiest and most important maintenance tasks homeowners can perform.
Furniture, rugs, and household items can block airflow from vents. Walk through your home periodically and make sure supply vents remain open and clear. Proper airflow helps distribute conditioned air evenly throughout the house.
Ceiling fans do not lower room temperatures. They help people feel cooler by improving air circulation. This often allows homeowners to maintain slightly higher thermostat settings without sacrificing comfort.
Homeowners often believe that setting the thermostat to a dramatically lower temperature will cool the house faster. This is a common misconception. Your air conditioner does not work like a gas pedal. If your home is currently 80 degrees and you want it to reach 74 degrees, setting the thermostat to 65 degrees will not make the cooling process happen faster. In fact, it just increases energy consumption and wear on your cooling system.
Professional maintenance helps identify issues before they cause breakdowns. Routine inspections can improve efficiency, reduce unexpected repairs, and help your cooling system operate more reliably throughout the summer.
Many everyday activities add heat to the home. Examples include:
Whenever possible, schedule these activities during cooler morning or evening hours.
Temperature is only part of the comfort equation. Humidity has a major impact on how indoor conditions feel. Excess moisture makes the air feel warmer and heavier. Lower humidity often makes a home feel cooler even when thermostat settings remain unchanged. According to the U.S. Environmental Protection Agency, maintaining proper indoor humidity can improve comfort and indoor air quality.
If your home feels uncomfortable despite reasonable thermostat settings, humidity may be contributing to the problem.
Understanding normal system behavior can help homeowners avoid unnecessary concern during periods of extreme heat. When temperatures reach the upper 90s or approach 100 degrees, air conditioning systems often work harder than usual.
This can result in:
These conditions do not automatically indicate a problem. In many cases, they simply reflect the demands being placed on the system.
The National Weather Service routinely records dangerous heat conditions throughout the CSRA region during the summer months. If your system continues maintaining comfortable indoor temperatures, longer run times may be entirely normal.
Homeowners throughout Augusta, Evans, and North Augusta frequently notice these patterns during the hottest weeks of the year. Understanding these behaviors helps separate normal operation from situations that require professional attention.
Programming your thermostat can improve comfort while helping reduce unnecessary energy use.
Most programmable thermostats allow homeowners to create daily schedules based on occupancy.
A typical summer schedule would include:
Consistency is important. Smart thermostats offer even greater flexibility. Many models learn household routines and make automatic adjustments based on usage patterns.
Some systems also provide energy reports that help homeowners understand how thermostat choices impact utility consumption. For homeowners across Augusta and Evans, programmable schedules are often among the easiest ways to improve cooling efficiency.
Older thermostats can limit system performance. Homeowners often still rely on outdated manual thermostats that provide limited control over indoor conditions.
Modern thermostat technology offers several advantages, such as:
A thermostat upgrade may not solve every cooling issue. However, it can improve control and convenience. In some homes, upgrading to a smart thermostat helps reduce unnecessary system operation while maintaining consistent comfort. Professional installation also ensures proper compatibility with existing HVAC equipment.
Homeowners throughout North Augusta, Martinez, Augusta, Grovetown, and Evans often find that thermostat upgrades provide meaningful improvements in both convenience and efficiency.
Finding the right thermostat setting during the summer is about balance. There is no universal temperature that works for everyone. Most homeowners feel comfortable between 72 and 76 degrees. Small adjustments can help improve efficiency without sacrificing comfort.
Remember that your air conditioner does not cool faster when the thermostat is set dramatically lower. During periods of extreme heat, longer run times are often normal. Many systems are simply working as designed. Good thermostat habits, proper humidity control, clean air filters, and preventive maintenance all contribute to better comfort and system performance.
