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

During the summer, running your air conditioning can be your highest monthly electrical expense. So, it’s only natural that you’re looking for ways to save. That could entail finding an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated unit with air conditioner installation.

Changing your air conditioning’s fan setting is a second way you can conserve money.

Your air conditioner works with a fan to dispatch the cool air it produces. You adjust this fan at your thermostat by changing it to “auto,” which indicates the fan will only run when the air conditioner is going. Or you can set it to “on,” which indicates it will work continuously.

Does putting your AC on “fan” save energy in Pacheco? Not necessarily. Usually, operating your air conditioner’s fan all day is going to drive up your energy bill slightly.

But it also provides a few pluses (and disadvantages) in relation to your family’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan operate all day can better equalize your family’s comfort. This is ideal if you have a two-story home, since areas upstairs can be warmer. It’s also ideal if you have problems with uneven cooling because of hot and cold spaces.

It’s also beneficial if one of your loved ones suffers from allergies, asthma or other respiratory illnesses. That’s since the air is consistently being circulated and filtrated. However, you may have to put in new air filters more regularly.

Having the fan on constantly can also make your energy bills more expensive. It could also cause the fan to wear out faster and need air conditioning repair.

Your house may also feel more moist. Air conditioning helps control humidity by removing wetness from the air. But if the fan is continuously on, it’s challenging for moisture to drain from the condenser externally.

Air Conditioner Fan Set to “Auto”

This is the highest energy-efficient setting, since the fan will only operate when your air conditioner does. It’s ideal if your residence always feels the right temperature, whichever room you’re in.

There are a few drawbacks to using the auto setting. You may run into hot and cold areas in your home and lower air quality. This is since air isn’t constantly being distributed or being repeatedly filtered.

On the other hand, you’ll use a lower amount of energy and won’t be required to switch you air filter as frequently. Both are savings that can add up over the year, so you’ll have to consider what’s best for your household.
