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

During the high temperatures, running your air conditioning can be your biggest monthly utility expense. So, it’s only natural that you’re checking for methods to use less energy. That may include finding an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated model with air conditioner installation.

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

Your air conditioner relies on a fan to dispatch the cold air it creates. You control this fan at your thermostat by setting it to “auto,” which means the fan will only run when the air conditioner is going. Or you can switch it to “on,” which means it will be on continuously.

Does putting your AC on “fan” save energy in Kingsville? Not necessarily. Generally, using your air conditioner’s fan all the time is going to make your energy bill slightly higher.

But it also offers a few pluses (and downsides) in regard to your residence’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan run all day can better equalize your home’s comfort. This is great if you have a two-story residence, since areas upstairs can be more hot. It’s also ideal if you have difficulties with unbalanced cooling because of hot and cold rooms.

It’s also advantageous if one of your family members deals with allergies, asthma or other respiratory symptoms. That’s because the air is consistently being circulated and filtered. On the flip side, you may have to switch your air filters more frequently.

Having the fan on constantly can also increase your energy bills. It could also result in the fan wearing out more quickly and need air conditioning repair.

Your residence may also seem more moist. Air conditioning helps control humidity by drawing moisture from the air. But if the fan is always running, it’s challenging for moisture to flow from the condenser externally.

Air Conditioner Fan Set to “Auto”

This is the most energy-efficient setting, as the fan will only run when your air conditioner does. It’s great if your residence always seems cool, whichever area you’re in.

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

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