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

During the high temperatures, using your air conditioning can be your biggest monthly utility cost. So, it’s given that you’re looking for ways to use less energy. That could entail trying an energy-efficient AC setting or even upgrading to an ENERGY STAR®-rated unit through air conditioner installation.

Switching 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 produces. You adjust this fan at your thermostat by switching it to “auto,” which means the fan will only be on when the air conditioner is working. Or you can set it to “on,” which means it will run constantly.

Does putting your AC on “fan” save energy in McHenry? Not necessarily. Typically, operating your air conditioner’s fan all day is going to drive up your energy bill slightly.

But it also gives a few advantages (and drawbacks) in regard to your residence’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan run continuously can better equalize your home’s comfort. This is ideal if you own a two-story house, since spaces upstairs can be hotter. It’s also good if you have difficulties with unbalanced cooling because of hot and cold spaces.

It’s also advantageous if one of your loved ones suffers from allergies, asthma or other respiratory issues. That’s due to the fact the air is consistently being dispersed and filtered. On the flip side, you may have to change your air filters more often.

Having the fan on all day 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 seem more humid. Air conditioning helps balance humidity by drawing water from the air. But if the fan is continuously working, it’s harder for moisture to flow from the condenser outside.

Air Conditioner Fan Set to “Auto”

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

There are a few disadvantages to using the auto setting. You may experience hot and cold areas in your house and decreased air quality. This is due to the fact air isn’t continuously being distributed or being constantly filtered.

On the flip side, you’ll need a lower amount of energy and won’t be required to get a new air filter as often. Both are savings that can add up throughout the year, so you’ll have to think over what’s best for your needs.
