AC Fan vs Auto: What Mode Should You Choose?
Summer temperatures can be unpredictable. On exceptionally hot days, you might be tempted to blast your air conditioning system at the lowest temperature and switch the fan setting from “auto” to “on.” But should you leave your AC fan on “auto” or “on”? Does one setting have more benefits than the other? Let’s take a look:
What’s the Difference Between Putting the Fan on Auto and On?
It’s critical to understand the difference between an AC fan vs. auto setting. When you look at your thermostat, you’ll see a section labeled “fan.” This refers to the blower fan, which is found in your air conditioner’s air handler. The air handler is responsible for sending cooled air out into your home once the cooling process has been completed.
If the setting is on “auto,” the fan only runs when your air conditioner has finished cooling air and is ready to send it out into your home. If the thermostat fan setting is switched to “on,” the fan will constantly blow air throughout your home — whether it has been cooled or not. Now that you know how these settings work and what they do, it’s time to find out if you should leave your AC fan on “auto” or “on.”
AC Fan vs. Auto: Which Is Best?
There’s a reason why you have the option to choose between the AC fan vs. auto setting; both choices have their benefits. However, each can have disadvantages as well. If you want to know if you should leave your AC fan on “auto” or “on,” you’ll want to see which benefits speak to you the most — and if any drawbacks turn you away.
“On” Setting: Pros and Cons
You can enjoy better indoor air quality if the fan is constantly running. Since the air throughout your home will be replaced at a quicker rate, you can potentially find relief against asthma and allergy symptoms.
However, letting your fan run continuously can have its drawbacks. You might need to replace your HVAC system’s air filter more frequently since you’ll be circulating air — and the dirt, pollen, and debris that can come with it — much quicker.
“Auto” Setting: Pros and Cons
Setting your thermostat fan setting to “auto” also has its advantages. For instance, your air conditioner is less likely to experience wear and tear since the fan won’t be running all the time. Letting your AC catch a break every once in a while will allow its various components to enjoy a longer lifespan. As a result, you can avoid the need for air conditioner repair services — or a full system replacement at the very worst.
At the same time, placing your fan on “auto” can have a few disadvantages. The most notable downside is that you could experience uneven cooling or warm spots throughout your home.
Does Turning Your AC Fan On Save Energy?
It’s always a relief to save money — especially when it comes to your utility bills. Unfortunately, when your air conditioner’s fan runs constantly, you can waste energy and raise your energy costs in the process. When setting the fan to “auto” instead, you can reduce your energy bills. These savings might not seem like much initially, but they can add up over time.
Saving money is no small thing. Many homeowners look for ways to cut down on energy costs, and often the first place they look is their air conditioning systems. Choosing between the AC fan vs. auto setting could be a no-brainer if you’re looking for ways to increase your home’s energy efficiency. You’ll save more energy with the “auto” setting in the long run.
