Best Thermostat Settings for Each Season
When it comes to keeping your home comfortable and your energy bills in check, the right thermostat settings can make all the difference. At THERRIAN MECHANICAL, we know that adjusting your thermostat by season helps you strike that perfect balance between coziness and efficiency. Here’s our straightforward guide to the best thermostat settings for each season to keep you cool in summer, warm in winter, and comfortable in between.
Spring & Fall: The Shoulder Seasons
Spring and fall are that sweet spot where the weather is mild, often letting you rely less on heating or cooling. During these seasons, set your thermostat to:
Daytime: 68°F (20°C)
Nighttime: Drop it a few degrees to around 60-62°F (15-17°C) when you’re asleep or away from home.
These settings optimize comfort while saving energy—especially if you take advantage of natural ventilation by opening windows during the day.
Summer: Stay Cool Without Overworking Your AC
Summer means longer, hotter days. The instinct might be to crank the AC, but keeping your thermostat too low can spike your energy costs. The U.S. Department of Energy recommends:
Daytime: 78°F (26°C)
Nighttime: You can raise it by a few degrees when you’re out or sleeping, ideally around 82°F (28°C).
If 78°F feels warm, consider using fans to circulate air more efficiently. They help the body feel cooler without pulling down the actual temperature.
Winter: Save Energy Without Freezing
When winter sets in, you want to stay warm but avoid unnecessary heating expenses. Here’s a solid baseline:
Daytime: 68°F (20°C)
Nighttime: Lower the thermostat to about 60°F (15°C) when you’re asleep or not home.
Lowering your thermostat by 10-15 degrees for 8 hours a day can save up to 10% annually on heating. Bundle up and embrace layers instead of keeping the heat too high.
Tips to Maximize Efficiency Year-Round
Use a programmable or smart thermostat. It automates temperature adjustments based on your schedule, so you’re never heating or cooling an empty home.
Seal leaks and insulate. Proper insulation keeps your home’s temperature stable and reduces the strain on your HVAC system.
Maintain your HVAC system regularly. Filters, ducts, and equipment need care to run efficiently.
Final Thoughts
Setting your thermostat isn’t about hitting one magic number; it’s about adjusting to your lifestyle and the seasons while keeping energy savings top of mind. With these simple seasonal guides, THERRIAN MECHANICAL hopes you’ll stay comfortable and save money all year long.
Because the right temperature isn’t just about comfort — it’s about smart living.
