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

During the hot weather, running your air conditioning can be your biggest monthly utility cost. So, it’s only natural that you’re checking for approaches to save. That might involve trying 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 a second way you can conserve money.

Your air conditioner uses a fan to deliver the cold air it produces. You manage this fan at your thermostat by switching it to “auto,” which signifies the fan will only run when the air conditioner is operating. Or you can set it to “on,” which means it will work continuously.

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

But it also gives a few advantages (and drawbacks) as far as your family’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

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

It’s also great if someone in your household has allergies, asthma or other respiratory illnesses. That’s due to the fact the air is constantly being dispersed and purified. On the other hand, you may have to install new air filters more often.

Having the fan on all day can also increase your energy bills. It could also cause the fan to wear out sooner and need air conditioning repair.

Your house may also seem more humid. Air conditioning helps control humidity by drawing wetness from the air. But if the fan is always on, it’s harder for moisture to drip from the condenser externally.

Air Conditioner Fan Set to “Auto”

This is the best energy-efficient setting, since the fan will only go when your air conditioner does. It’s great if your house always feels comfy, whichever room you’re in.

There are a few drawbacks to using the auto setting. You might run into hot and cold areas in your home and reduced air quality. This is because air isn’t always being distributed or being constantly filtered.

On the other hand, you’ll require reduced energy and won’t need to replace your air filter as often. Both are savings that can add up during the year, so you’ll have to think about what’s right for your home.
