Living in Central Texas means experiencing scorching summers, mild winters, and unpredictable weather in between. Your HVAC system works hard all year to keep your home comfortable, but using the best HVAC settings for your Texas home can make a big difference in energy efficiency — and your monthly bills.

At Weir Texas AC & Heat, we help Central Texas homeowners find the right balance between comfort and savings. Whether you’re cooling your home in July or trying to take the edge off a February cold snap, here’s what you need to know.


Ideal HVAC Settings for Texas Summers

In the heat of a Texas summer, it’s tempting to keep the thermostat as low as possible. But that can lead to sky-high utility costs and unnecessary strain on your system.

Recommended Summer Settings:

  • When you’re home and awake: Set your thermostat to 78°F

  • When you’re away from home: Bump it up to 85°F

  • When sleeping: Try 74–78°F, depending on personal comfort

These settings are based on guidelines from the U.S. Department of Energy, and they’re a great starting point for optimizing your cooling routine.

To take it a step further, consider using ceiling fans to make rooms feel cooler without lowering the temperature. Every degree you raise the thermostat can save 3–5% on cooling costs — making this one of the best HVAC settings for your Texas home in the long run.


Ideal HVAC Settings for Texas Winters

Winters in Central Texas may not be harsh, but there are still chilly nights that call for heat. To stay comfortable without overpaying, follow these winter thermostat recommendations:

Recommended Winter Settings:

  • When you’re home and awake: Set to 68°F

  • When you’re away or asleep: Drop it to 60–65°F

Lowering the heat while you sleep or when you’re not home helps reduce your energy use without sacrificing comfort. A programmable or smart thermostat makes these adjustments automatic — no need to remember to change it manually.


Best Year-Round HVAC Practices for Texas Homes

Choosing the best HVAC settings in a Texas home goes beyond just temperature. Here are a few extra tips to improve efficiency and extend the life of your system:

1. Install a Smart Thermostat

Smart thermostats learn your routine and automatically adjust your HVAC settings based on when you’re home, away, or asleep. Many also give you energy usage insights and alerts if something’s not right.

2. Use Zoning (If Available)

If your HVAC system supports zoning, adjust different areas of your home separately. For example, you can keep the bedrooms cooler at night without overcooling the rest of the house.

3. Schedule Regular Maintenance

Even the best thermostat settings won’t help much if your system isn’t running efficiently. At Weir Texas AC & Heat, we recommend twice-yearly HVAC tune-ups — once in the spring for cooling, and once in the fall for heating.

4. Seal Leaks and Insulate

Air leaks around windows, doors, and ducts can undermine even the most energy-efficient settings. Sealing those gaps can significantly improve your HVAC performance year-round.
