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

July 16, 2020

During the high temperatures, operating your air conditioning can be your biggest monthly electrical cost. So, it’s given that you’re seeking methods to use less energy. That may entail using an energy-efficient AC setting or even upgrading to an ENERGY STAR®-rated system with air conditioner installation.

Adjusting your air conditioning’s fan setting is another way you can spend less money.

Your air conditioner relies on a fan to deliver the cool air it makes. You adjust this fan at your thermostat by changing it to “auto,” which means the fan will only run when the air conditioner is running. Or you can switch it to “on,” which signifies it will be on all the time.

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

But it also has a few pluses (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 balance your house’s comfort. This is great if you have a two-story residence, since areas upstairs can be hotter. It’s also great if you have issues with inconsistent cooling on account of hot and cold rooms.

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

Having the fan on all the time can also drive up your energy bills. It could also make the fan wear out prematurely and need air conditioning repair.

Your house may also seem more moist. Air conditioning helps manage humidity by removing moisture 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 best energy-efficient setting, since the fan will only operate when your air conditioner does. It’s great if your residence always appears pleasant, whichever spot 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 always being distributed or being repeatedly filtrated.

On the other hand, you’ll need a lower amount of energy and won’t need to replace your air filter as regularly. Both are savings that can tally up over the year, so you’ll have to consider what’s right for your needs.
