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

During the hot weather, running your air conditioning can be your highest monthly electricity expense. So, it’s normal that you’re seeking approaches to save. That can entail finding an energy-efficient AC setting or even stepping up to an ENERGY STAR®-rated system through air conditioner installation. Changing your air conditioning’s fan setting is another way you can save money. Your air conditioner works with a fan to distribute the cool air it creates. You control this fan at your thermostat by switching it to “auto,” which signifies the fan will only run when the air conditioner is cooling. Or you can adjust it to “on,” which means it will be on constantly. Does putting your AC on “fan” save energy in Portland? Not necessarily. Usually, running your air conditioner’s fan all the time is going to make your energy bill slightly higher. But it also has a few perks (and downsides) as far as your family’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan operate all day can better equalize your house’s comfort. This is good if you own a two-story house, since spaces upstairs can be hotter. It’s also great if you have difficulties with uneven cooling on account of hot and cold rooms. It’s also advantageous if one of your family members suffers from allergies, asthma or other respiratory issues. That’s because the air is constantly being circulated and filtrated. However, you may have to install new air filters more regularly. Having the fan on all the time can also drive up your energy bills. It could also cause the fan to wear out more quickly and need air conditioning repair. Your home may also seem more moist. Air conditioning helps balance humidity by clearing water from the air. But if the fan is constantly 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, because the fan will only operate when your air conditioner does. It’s ideal if your home always feels the right temperature, whichever area you’re in. There are a few downsides to using the auto setting. You could run into hot and cold locations in your residence and reduced air quality. This is because air isn’t continuously being distributed or being repeatedly filtrated. That said, you’ll consume a lower amount of energy and won’t be required to get a new air filter as often. Both are savings that can build up during the year, so you’ll have to think over what’s ideal for your home.
