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

July 16, 2020

During the hot weather, operating your air conditioning can be your largest monthly electrical charge. So, it’s only natural that you’re seeking ways to use less energy. That could entail trying an energy-efficient AC setting or even making the switch to an ENERGY STAR®-rated system during air conditioner installation.

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

Your air conditioner relies on a fan to distribute the cold air it makes. You manage this fan at your thermostat by setting it to “auto,” which signifies the fan will only run when the air conditioner is working. Or you can set it to “on,” which indicates it will operate continuously.

Does putting your AC on “fan” save energy in Lake Forest? This isn’t always the case. Generally, using your air conditioner’s fan constantly is going to drive up your energy bill slightly.

But it also has a few advantages (and drawbacks) when it comes to your residence’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

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

It’s also advantageous if one of your family members suffers from allergies, asthma or other respiratory problems. That’s due to the fact the air is consistently being distributed and purified. However, you may have to replace your air filters more often.

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

Your house may also feel more moist. Air conditioning helps balance humidity by drawing wetness from the air. But if the fan is continuously running, it’s more difficult for moisture to flow from the condenser outdoors.

Air Conditioner Fan Set to “Auto”

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

There are a few downsides to using the auto setting. You could experience hot and cold spots in your residence and reduced air quality. This is since air isn’t constantly moving or being repeatedly filtrated.

That said, you’ll consume a lower amount of energy and won’t need to get a new air filter as frequently. Both are savings that can tally up throughout the year, so you’ll have to think about what’s best for your needs.
