Which Takes Less Energy? AC Fan On or in Auto?

July 16, 2020

During the high temperatures, using your air conditioning can be your biggest monthly electricity charge. So, it’s normal that you’re seeking methods to use less energy. That may include using an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated model with air conditioner installation.

Changing your air conditioning’s fan setting is an additional way you can spend less money.

Your air conditioner works with a fan to dispatch the cold air it creates. You control this fan at your thermostat by changing it to “auto,” which signifies the fan will only be on when the air conditioner is running. Or you can set it to “on,” which means it will operate continuously.

Does putting your AC on “fan” save energy in Houston? This isn’t always the case. Generally, running your air conditioner’s fan constantly is going to make your energy bill slightly higher.

But it also has a few pluses (and drawbacks) as far as your home’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan operate all day can better balance your house’s comfort. This is great if you own a two-story home, since areas upstairs can be warmer. It’s also ideal if you have difficulties with uneven cooling on account of hot and cold areas.

It’s also good if someone in your household has been diagnosed with allergies, asthma or other respiratory illnesses. That’s because the air is continuously being distributed and filtered. On the other hand, you may have to install new air filters more regularly.

Having the fan on all the time can also drive up your energy bills. It could also make the fan wear out sooner and need air conditioning repair.

Your home may also appear more humid. Air conditioning helps manage humidity by removing moisture from the air. But if the fan is continually going, it’s challenging for moisture to flow from the condenser externally.

Air Conditioner Fan Set to “Auto”

This is the highest energy-efficient setting, as the fan will only work when your air conditioner does. It’s ideal if your home always appears the right temperature, regardless of which area you’re in.

There are a few disadvantages to using the auto setting. You might run into hot and cold spots in your residence and lower air quality. This is because air isn’t continuously flowing or being repeatedly filtrated.

On the flip side, you’ll use a lower amount of energy and won’t have to switch you air filter as frequently. Both are savings that can tally up over the year, so you’ll have to think over what’s ideal for your household.
