BLOG Stay Cool and Save: The Best Thermostat Settings for Each Season Nov 28, 2025

As each season rolls in, homeowners often face the challenge of finding the right thermostat settings to maintain comfort while managing energy costs. At AmeriKool Mechanical Services, we understand the importance of balancing these factors, especially with fluctuating weather conditions. Whether you're trying to beat the summer heat or stay cozy in the winter chill, setting the thermostat correctly can make all the difference.

Understanding the best thermostat settings year-round can not only enhance comfort but also lead to significant energy savings. The key is adapting to the natural shifts in temperature and optimizing your HVAC system for efficiency.

In the summer, the goal is to keep your home cool without breaking the bank on energy bills. The U.S. Department of Energy recommends setting your thermostat to 78°F when you’re at home. This setting strikes a balance between comfort and cost. While you’re away, consider raising it to 85°F. This adjustment ensures that your air conditioning doesn’t work overtime in an empty house, thus saving energy and reducing wear on your system.

As the leaves turn and fall approaches, you’ll want to adjust your thermostat to cozy up your living space without unnecessary energy waste. For fall, a setting around 68°F is recommended during the day when you're home. At night or when you're not at home, lower the setting by 10 to 15 degrees. This strategy is not only energy-efficient but is also a great way to save up to 10% annually on heating costs.

Winter demands increased heating, but setting your thermostat too high can lead to a spike in energy expenses. AmeriKool suggests maintaining a setting of 68°F while you're awake and active at home. During sleeping hours or when the house is unoccupied, lower your thermostat to 60°F. This reduction enables considerable savings, as heating systems tend to consume more energy at higher settings.

Spring brings mild weather, which might tempt you to turn your HVAC system off entirely. Instead, use this season to find a comfortable middle ground — typically around 65°F to 70°F during active hours, letting you minimize your system's operation without compromising comfort. Nights still might be chilly, so slight adjustments might be necessary.

Adjusting thermostats manually every so often can become a tedious task. We recommend investing in a programmable or smart thermostat. These devices allow for effortless control of your home’s temperature settings, optimizing them according to your lifestyle and preferences automatically. They are a smart investment that can lead to significant cost savings in the long run.

Furthermore, regular maintenance of your HVAC system by professionals can ensure its efficiency throughout the year. The team at AmeriKool Mechanical Services is always ready to assist with tune-ups, ensuring your unit operates at its best no matter what the season.

Being proactive with your thermostat settings is an effective way to manage energy usage and costs while keeping your home comfortable across all seasons. By following these guidelines, you'll enjoy a relaxed environment and won't be caught off guard by unexpected spikes in your energy bill.
