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

July 16, 2020

During the summer, using your air conditioning can be your largest monthly electricity cost. So, it’s only natural that you’re looking for methods to use less energy. That may involve using an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated system with air conditioner installation.

Regulating your air conditioning’s fan setting is an additional way you can conserve money.

Your air conditioner relies on a fan to deliver the cold air it makes. You adjust this fan at your thermostat by switching it to “auto,” which signifies the fan will only be on when the air conditioner is cooling. Or you can adjust it to “on,” which indicates it will work constantly.

Does putting your AC on “fan” save energy in Westerville? This isn’t always the case. Typically, operating your air conditioner’s fan all the time is going to drive up your energy bill slightly.

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

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan go continuously can better balance your home’s comfort. This is ideal if you own a two-story residence, since spaces upstairs can be warmer. It’s also ideal if you struggle with uneven cooling on account of hot and cold spaces.

It’s also beneficial if one of your loved ones deals with allergies, asthma or other respiratory symptoms. That’s since the air is consistently being dispersed and purified. However, you may have to install new air filters more frequently.

Having the fan on all day can also drive up your energy bills. It could also cause the fan to wear out more quickly and need air conditioning repair.

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

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 great if your residence always seems the right temperature, no matter what area you’re in.

There are a few disadvantages to using the auto setting. You might experience hot and cold spots in your residence and decreased air quality. This is due to the fact air isn’t constantly flowing or being continuously filtrated.

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