Should You Keep Your AC’s Fan in ‘On’ Mode?

AC's Fan

As a Loxley, Alabama, homeowner, you’re no stranger to hot, humid summers. To beat the heat, you might be tempted to set your air conditioner’s fan to “on” at all times. Learn why always keeping your air conditioner on can compromise comfort and lead to high utility bills.

High Humidity Levels

Your air conditioner does much more than cool your home. It’s also responsible for maintaining a healthy and comfortable humidity level. When the fan is always on most air conditioners will cool quickly without properly dehumidifying the air. During an Alabama summer, high humidity can lead to dust mites, mold growth, and other indoor air quality concerns.

Dirty Air Filters

One of the benefits of running your air conditioner constantly is that you’ll cycle air through your home continuously. That means the HVAC system’s air filter will trap most of your home’s airborne contaminants, such as pet dander, dust, and mold.

With constant fan usage, however, it is possible that you will need to change air filters more frequently. The frequency with which your filter is to be changed will depend on the type of filter, but regardless of which filter you use, you will need to replace them more frequently when the system is set to “on” instead of “auto.”

Excessive Utility Bills

It should come as no surprise that keeping your air conditioner running at all hours of the day will lead to high utility bills. To enjoy the benefits of constant air filtration and superior comfort that come with constant fan operation, consider investing in an Infinity 21 central air conditioner.

This system relies on a variable-speed blower that enables it to run at a low level most of the time and turn up the cooling power when necessary. With innovative technology like this, you can easily set the air conditioner to “auto” and stay cool without racking up excessive utility bills.
