Thermostats can get confusing with all of the available programming options for setting the air conditioning for your home. Some features depend on your personal preference, such as what temperature to set the dial. Other AC settings may not be as straightforward…
Cool down – there’s no need to get frustrated and confused! In this post, our knowledgeable technicians at ACHV Services share whether “on” or “auto” is the more suitable option for your air conditioning.
“On” & “Auto”… What’s the Difference?
Before making any changes, you need to understand some key differences between the two settings.
Both “on” and “auto” settings control the air conditioner fan but differently impact when the fan is in motion.
Setting your AC unit to “auto” restricts the fan to only running at specific times. Your thermostat is constantly evaluating the temperature of your home. When the temperature rises above the designated temperature, the system will begin a cooling cycle by automatically turning the fan on. After your home is back to baseline, the fan shuts off.
If your air conditioner is set to “on,” the fan is always running, even when your home is already cool.
What Are the Pros and Cons of Auto?
There are benefits and disadvantages to both settings. When your system is set to “auto,” your system will provide:
- Higher efficiency
- Lower energy bills
- Better humidity control
- Less wear and tear on certain components
- Less noise from your AC system
With all of these benefits, there are still some drawbacks to the auto setting. Your home will likely have hot and cool spots, so some rooms may feel a bit stuffier. Plus, your home will have poorer air filtration.
While some components may experience less wear and tear, the blower motor may wear out faster from frequent starting and stopping.
What About On?
Keeping your fan on at all times will provide even cooling throughout your home. Additionally, you will have improved air circulation and filtration. The blower motor will experience less wear and tear from the constant back and forth.
One major drawback is increased cooling costs. Plus, you will need to replace your air filters more regularly to keep up.
On or Auto: How Do I Choose?
A major determining factor when it comes to deciding between these two settings is your climate. In Florida, we have to consider our hot, humid weather.
Your air conditioner contains pieces called evaporator coils, which create the cool air that gets blown through your home. High levels of moisture in the air can cause condensation to build up on the evaporator coils, which then gets blown through your home and increases the humidity levels.
Setting your AC unit to “auto” reduces the amount of moisture in your home, making the space feel cooler and more comfortable, especially during muggy summer months.
Be Smart About Your AC
Wondering ‘Should I Install a Smart Thermostat?’ Well, installing a programmable or smart thermostat can give you the perfect amount of flexibility to make your home feel custom-cooled just for you.
- A programmable thermostat allows you to set the AC depending on the time of day, week, and year!
- A smart thermostat gives you even more control by allowing you to change the temperature from your phone no matter where you are in the world.
Greater control means greater comfort!
