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

During the hot weather, operating your air conditioning can be your largest monthly electrical expense. So, it’s given that you’re checking for ways to consume less energy. That might include using an energy-efficient AC setting or even upgrading to an ENERGY STAR®-rated system during air conditioner installation.

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

Your air conditioner uses a fan to distribute the cool air it makes. You adjust this fan at your thermostat by setting it to “auto,” which signifies the fan will only be on when the air conditioner is going. Or you can set it to “on,” which signifies it will operate continuously.

Does putting your AC on “fan” save energy in Oxford? Not always. Usually, using your air conditioner’s fan constantly is going to make your energy bill slightly higher.

But it also has a few perks (and drawbacks) in relation to your family’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

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

It’s also good if one of your family members has allergies, asthma or other respiratory symptoms. That’s since the air is continuously being dispersed and filtrated. However, you may have to put in new air filters more frequently.

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

Your house may also appear more humid. Air conditioning helps control humidity by extracting moisture from the air. But if the fan is continually working, it’s harder for moisture to drip from the condenser outside.

Air Conditioner Fan Set to “Auto”

This is the most energy-efficient setting, because the fan will only operate when your air conditioner does. It’s good if your home always seems the right temperature, regardless of which spot you’re in.

There are a few downsides to using the auto setting. You could have hot and cold areas in your home and reduced air quality. This is because air isn’t constantly flowing or being constantly filtered.

On the other hand, you’ll use reduced energy and won’t need to change your air filter as frequently. Both are savings that can build up over the year, so you’ll have to think over what’s ideal for your family.
