Knowing the best thermostat setting when away helps balance comfort, energy efficiency, and long-term system health. In Kyle and Buda, Texas, the challenge is managing both heat and humidity in summer, then keeping things warm enough to prevent frozen pipes in winter.
This guide explains the ideal thermostat settings for an empty house during the day, backed by recommendations from the U.S. Department of Energy (DOE) and ENERGY STAR.
You’ll learn how to adjust your system by season, when to make exceptions, and how smart thermostats can simplify the process while saving up to 10% on your energy bill each year.
Is It More Efficient to Leave the Thermostat at One Temperature?
No, that’s a common myth.
Many homeowners believe it’s better to keep the thermostat at one constant temperature all day, assuming it takes more energy to cool or heat the home again later.
The U.S. Department of Energy confirms the opposite: allowing your home’s temperature to rise or fall slightly while you’re away actually reduces total energy use.
Here’s why:
- Your HVAC system works against the difference between indoor and outdoor temperatures.
- When you let your home warm up a few degrees in summer or cool down a few degrees in winter, that difference shrinks.
- With less difference to overcome, your system runs less and uses less energy overall.
Best Thermostat Setting When Away in Summer
Summers in Kyle and Buda can reach the upper 90s with humidity to match. Your air conditioner works hard, and leaving it on full blast while you’re out wastes energy and money. But turning it off completely can raise humidity indoors and cause other issues.
Recommended Range (ENERGY STAR):
- 78°F when home
- ~85°F when away for the day
DOE Guidance: Keep your home “warmer than usual when you are away,” adjusting the temperature 7–10°F higher than your normal setting.
Why It Works:
- Reduces energy usage during peak afternoon hours.
- Keeps indoor humidity below 60%, helping prevent mold and mildew.
- Limits strain on your HVAC system, extending its lifespan.
For Kyle and Buda Homes
Homes here often deal with humid summer air and bright sun exposure. Avoid going above 85°F indoors while away to control humidity and protect finishes. If your home traps heat easily, set 80–83°F instead and use ceiling fans to circulate air when you return.
Tip: Smart thermostats can monitor humidity and automatically adjust cooling before you get home, so the space is comfortable without wasting energy.

Best Thermostat Setting When Away in Winter
While Kyle and Buda winters are mild, overnight cold snaps can still dip below freezing. If your thermostat is set too low, pipes can freeze and burst – an expensive and preventable repair.
Recommended Range (ENERGY STAR):
- 68°F when home
- ~60°F when away for the day
DOE Guidance: Lower the thermostat 7-10°F from your typical setting while away or asleep to save energy safely.
Why It Works:
- Reduces heating costs without risking frozen pipes.
- Keeps indoor temperatures stable during brief Texas cold fronts.
- Protects your HVAC system from short-cycling due to extreme swings.
For Kyle and Buda Homes
Set your thermostat between 60–62°F during short absences. For longer trips or very cold nights, avoid dropping below 58°F. Homes built on slab foundations (common in this area) are especially prone to pipe issues in freezing conditions.
Tip: On freezing nights, open cabinet doors under sinks and let faucets drip slightly to maintain water flow and pressure.
Spring and Fall Settings
In Kyle and Buda, spring and fall bring mild weather, meaning you can often turn your HVAC system off entirely during the day.
Keep these rules in mind:
- Maintain indoor humidity below 60% to avoid mold growth.
- Use ceiling fans or cracked windows to keep air moving.
- Consider a small dehumidifier during extended rain or high humidity.
The Role of Smart and Programmable Thermostats
Upgrading to a smart thermostat makes energy savings easy. You can set a schedule for work hours, weekends, and trips, and adjust settings through an app.
Example Schedule for Kyle and Buda Homes:
- Summer: 78°F when home, 85°F when away.
- Winter: 68°F when home, 60°F when away.
Why It Matters:
A programmable thermostat can automatically make those 7–10°F adjustments that the DOE recommends, saving up to 10% annually on heating and cooling. Some models also monitor humidity, which is especially useful for our humid summer months.
DOE Tip: Every degree you raise or lower the thermostat for at least 8 hours saves about 1% on energy costs.
Key Takeaways
- Best thermostat setting when away: ~85°F in summer, 60°F in winter.
- Follow DOE and ENERGY STAR guidance: Adjust by 7–10°F for 8 hours a day for up to 10% savings annually.
- Avoid turning your system off completely to prevent humidity or freezing problems.
- Smart thermostats keep comfort consistent and reduce energy waste.
- Kyle and Buda homes benefit most from steady, moderate temperature control due to high humidity and seasonal swings.
Frequently Asked Questions
Not in Texas. Shutting your system off allows indoor humidity to climb in summer and can cause freezing issues in winter. Small, consistent adjustments are safer and more efficient.
For short absences, aim for 78–82°F in summer and 60°F or above in winter. Avoid sudden temperature changes.
No. Adjusting within safe ranges actually reduces strain and extends lifespan.
Humidity makes warm air feel hotter. Keeping humidity below 60% allows higher temperature settings to feel comfortable without overcooling.
For trips over a few days, raise summer settings to 85–88°F and lower winter settings to 55–58°F. That saves energy without risking damage.
