There can be some debate over what the best setting is for the fan when running the AC. Some people say that it should always be on “auto,” while others believe that it’s better to have it on “on.” So, which one is the right setting?
If you’re after the most energy-efficient option, keeping your fan on “AUTO” will be your best bet. If you want to stay at your desired temperature and don’t mind the energy bill, you’ll want to keep it set to “ON”.
Let’s dive in and look at this closer.
Pros of Keeping Your Thermostat Fan setting on Auto
Keeping your fan on “auto” can help to preserve more energy.
When the fan is on “auto,” it will only run when it’s needed. This means that you won’t be wasting energy by having the fan running all the time, even when it’s not needed.
One final reason to keep your air conditioner fan on “auto” is that it can help to protect your AC unit.
When the fan is on “on,” it can cause the AC unit to work harder than it needs to.
This can lead to the AC unit wearing out sooner than it should and could end up costing you a lot of money in the long run.
Cons of Keeping Your Thermostat Fan Setting on Auto
You’ll find that by keeping your thermostat on auto, you may have less distribution of cold or hot air around your home.
You may also feel that the temperature doesn’t stay constant as your AC turns itself off, only to turn itself back on when it reaches the threshold temperature.
If you want a constant cool breeze in your home, then you’ll prefer the “ON” setting.
Pros Keeping Your Thermostat to ON
Your thermostat set on “ON” will always be providing air at the temperature you set, no matter what. This will keep you extra cold as you won’t have any dips in temperature.
Another reason to keep the AC on “on” is if you’re trying to fall asleep. Having the thermostat on “ON” will provide constant cooling, and you won’t wake up hot and sweaty.
Cons of Keeping Your Thermostat to ON
One downside with air conditioners that have the setting switched to “on” is that it can use a lot of energy.
This is because the fan is always running, even when the AC isn’t working via a cooling cycle. So, if you have a room that’s already cold, then your AC will be doing extra work for no real benefit.
Verdict: Should You Run the AC on Auto or ON?
Ultimately, it’s up to you whether you want to keep your fan setting on “auto” or “on.” However, it’s important to weigh the pros and cons of each setting before making a decision on what the best setting is for your AC.
By understanding the benefits and drawbacks of each setting, you can make a decision that’s best for you and your home to achieve the most out of your HVAC system and indoor air quality.
