How & When to Use Your Thermostat’s Fan Setting in Slidell, LA

If you’re like many Slidell, LA homeowners, you probably never touch your air conditioner thermostat’s fan setting. While that’s not necessarily a bad thing, learning more about this oft-ignored setting can help you use it to your advantage.

Understanding Your Thermostat Fan Setting

Most thermostats traditionally have two fan settings: “Auto” and “On.” When set to “Auto,” the fan automatically starts and stops in time with your heating and cooling cycles. In “On” mode, the fan continues to operate non-stop even when the rest of your HVAC system isn’t running. You can switch between modes at any time with the press of a button, but which setting should you choose?

When To Keep Your Thermostat on Automatic

Generally speaking, it’s best to keep your fan set to automatic mode in most situations. This ensures that your fan only runs when it’s needed, keeping energy usage to a minimum. Sticking with the “Auto” setting also reduces wear and tear, extending the lifespan of your equipment. Of course, keeping up with routine maintenance is still important to protect the health of your system.

When To Turn On Your HVAC Fan

Letting your fan run continuously usually isn’t a good idea, but it can be beneficial in some circumstances. Most notably, it increases ventilation by keeping air flowing through your home. It also allows more air to pass through your HVAC filter, improving indoor air quality. This is especially useful if you’re cleaning, cooking or doing other activities that generate particulate matter. The always-on setting can also promote more uniform air distribution, but use it sparingly on humid days. Without air conditioning, constant airflow can pull more moisture indoors and make your house oppressively humid.
