Improving your home’s energy efficiency is achievable. It’s a matter of knowing which areas to improve. One of the things you need to look at is how to adjust your thermostat correctly. Discover how this device’s settings can help you save money on utility costs.

Creating the ideal temperature in your home can be as simple as knowing how to set the thermostat. This small device determines how long your fan will distribute the conditioned air.

Knowing when you should keep your thermostat on auto or on will help you make your home more comfortable. It can also help you improve your HVAC efficiency, leading to lower utility costs in the long run.

Understanding the Difference Between On and Auto on the Thermostat

The settings on your thermostat can make a huge difference in your home’s comfort levels and energy consumption. Both the on and auto settings have their share of pros and cons. Familiarizing yourself with them will help you determine which setting suits your home better.

What is the On Setting?

The “on” setting makes your fan run continuously even though the HVAC system isn’t cooling or heating the air.


“Constant airflow moves air particles toward the filters all the time, improving air quality in the room.”

  • There will be fewer hot and cold spots in the home, resulting in a more comfortable environment.
  • The fan will have fewer stop-and-start cycles, which prevent premature wear and extend its lifespan.
  • The fan’s constant activity will result in higher energy consumption, which will be reflected in your electricity bills.
  • The HVAC system’s filters will need to be replaced more often.
  • The constant movement can damage the fan, especially if it’s never turned off.

What is the Auto Setting?

The “auto” setting means that your fan will only turn on when the HVAC system is running. The entire system will shut off once the thermostat reaches the pre-set temperature.

  • This setting uses less energy, which lowers monthly electricity costs.
  • It offers better control because you specify at which temperature the system turns on and off.
  • It provides convenience because you don’t have to get up from your seat or bed to turn it on or off.
  • The home’s air quality will decrease because the air isn’t always moving and passing through filters.
  • There will be more hot and cold spots because conditioned air isn’t distributed evenly throughout the home.
  • The frequent stop-and-start cycles can cause excess wear on the fan and shorten its lifespan.

Should you keep your thermostat on auto or on? The answer depends on your personal preferences, home location, and HVAC system’s performance.

The Best Thermostat Setting for Your Home

Now that you understand the difference between auto and on settings better, you can wisely set your thermostat.

Can your HVAC system handle it?

If you have a high-efficiency HVAC system, you can take advantage of the benefits of the “on” setting. However, you should consider investing in a cooling and heating repair home service for preventive maintenance.

If you’re worried about the cost of this service, you can choose the “auto” setting and optimize it to suit your home’s architecture and the surrounding environment.

What’s the weather outside?

You might be wondering what’s the most energy-efficient temperature to keep your house comfortable in the winter. Alternatively, a version of the question might pop up once summer is here.

The U.S. Department of Energy claims that you can save at least 10% in heating and cooling annually with the right thermostat setting. This is done by setting the thermostat back daily by 7°-10°F for eight hours from its normal setting.

  • In the winter, set the thermostat to 68°F during the day before lowering it at night or when you’re away.
  • In the summer, set the thermostat to 78°F when you’re at home and increasing the temperature when you’re away. By keeping the indoor temperature close to the outdoor temperature, you create humidity control and effectively lower your cooling costs.

The best thermostat setting for your home depends on what you want. What’s important is that you choose the setting that fits your lifestyle and budget.
