Should My Air Conditioning Fan Be On Auto or On?

Should My Air Conditioning Fan Be On Auto or On?

When it comes to running your home’s air conditioning fan, many homeowners are concerned about finding the most cost-effective and efficient way to do so without causing unnecessary strain on the unit. The decision often comes down to choosing between leaving the fan on “auto” or selecting the “on” function.

This is a common question that our technicians at Weikle’s Hometown Heating & Air are frequently asked by people looking to optimize their system’s energy efficiency and cooling performance. However, there is no one-size-fits-all solution.

To better understand the differences between the two options, let’s explore the purpose of each setting.

How Your Air Conditioner’s “Auto Mode” Works

Auto mode essentially means that your air conditioner’s air circulation is managed automatically. In practical terms, when the thermostat detects a room with warm air, the air conditioner will begin cooling that area. Once the thermostat senses that the room has reached the desired temperature, the air conditioner will automatically shut off.

Using Auto mode is the most energy-efficient option for your unit, as it only operates when there is a need to cool the room. However, the automatic on-off cycles can lead to increased stress on the air handler components, including the air filter, compressor, blower motor, and evaporator coil. This can result in more wear and tear on these parts, potentially shortening the lifespan of your air conditioner.

How the “On Mode” Works

When the “On Mode” is activated, the fan runs continuously at full power, ensuring a consistent cooling effect regardless of the room temperature. Although this setting may lead to higher energy consumption, it helps minimize the strain on the air handler components caused by frequent cycling.

For instance, during hotter or more humid periods of the day, the “On Mode” can enhance your comfort more rapidly by accelerating the cooling process. However, it is not advisable to keep this mode on constantly as it is neither efficient nor beneficial for the unit’s components.

The Difference Between Auto vs. On

Setting your air conditioner to Auto mode means you’ll save on energy efficiency, and the temperature of your home will be more consistent. On the other hand, setting your AC to On mode will maximize your unit’s overall performance and put less strain on it, but at the cost of saving energy.

So, Which Should You Use?

Are you still having trouble choosing between Auto and On mode for your air conditioning fan? Generally, for consistent comfort and energy efficiency, the Auto feature is recommended. However, if you prefer tighter control over your unit’s performance during specific peak times, the On mode (on a timer) may be more suitable.
