During the summer, operating your air conditioning can be your highest monthly utility cost. So, it’s only natural that you’re seeking approaches to save. That may involve trying an energy-efficient AC setting or even upgrading to an ENERGY STAR®-rated model during air conditioner installation. Changing your air conditioning’s fan setting is another way you can conserve money. Your air conditioner uses a fan to dispatch the chilled 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 working. Or you can set it to “on,” which indicates it will operate all the time. Does putting your AC on “fan” save energy in The Bay Area? Not necessarily. Generally, running your air conditioner’s fan all day is going to drive up your energy bill slightly. But it also gives a few advantages (and disadvantages) in regard to your residence’s comfort. Here’s why.

Air Conditioner Fan Set to “On”

Having your air conditioner’s fan run all day can better equalize your family’s comfort. This is ideal if you live in a two-story home, since spaces upstairs can be warmer. It’s also ideal if you have issues with uneven cooling because of hot and cold spaces. It’s also good if one of your family members has been diagnosed with allergies, asthma or other respiratory symptoms. That’s because the air is continuously being distributed and purified. On the other hand, you may have to replace your air filters more often. Having the fan on constantly can also drive up your energy bills. It could also result in the fan wearing out prematurely and need air conditioning repair. Your residence may also feel more humid. Air conditioning helps balance humidity by extracting water from the air. But if the fan is constantly working, it’s challenging for moisture to drain from the condenser externally.

Air Conditioner Fan Set to “Auto”

This is the highest energy-efficient setting, since the fan will only operate when your air conditioner does. It’s great if your house always feels pleasant, regardless of which spot you’re in. There are a few drawbacks to using the auto setting. You may have hot and cold locations in your residence and reduced air quality. This is since air isn’t always flowing or being continuously purified. On the other hand, you’ll need a lower amount of energy and won’t have to get a new air filter as frequently. Both are savings that can add up during the year, so you’ll have to think about what’s best for your home.
