Why Does My Air Conditioner Have a Fan Mode?

Turning on a conventional fan is cheaper than running an air conditioner. But what about running your air conditioner in fan mode? Many people see the option of a fan mode on their AC unit without knowing what it means, along with several other modes. Here’s what you need to know about all your AC unit has to offer.

Understanding the Air Conditioner Fan Mode

Air conditioner fan mode will make the machine work like a fan. It will only blow and circulate air without cooling it. The practice may cause a cooling sensation due to the breeze hitting your skin. However, the air temperature will not decrease a little bit.

Running your AC in fan mode will indeed save some energy consumption because your AC compressor would not have to work. Experts recommend you to try this trick during cool weather when you don’t need the temperature to decrease. You can also turn on the fan mode after your AC reaches your ideal air temperature.

Any Other Modes to Know

If you take a look at your AC remote, you likely see other modes. Here’s what they will do if you use them.

Cool Mode

Cool mode is the regular AC setting. This mode will run your AC steadily to maintain the temperature and fan speed as you set them. People choose this mode to keep their utmost comfortable environment.

Dry Mode

Sometimes, it is not the air temperature that causes discomfort but the humidity instead. By setting your AC in dry mode, your AC will not have to work to reach lower temperatures. Even fan speed can go slow if needed. Your AC will focus on removing extra moisture in the air. This mode is suitable during rainy days or if you live near the sea.

Power Saver Mode

This setting enables the compressor to automatically shut down after it hits the target temperature set on the thermostat. Don’t worry, as it will automatically turn on again when the temperature needs cooling again. As such, you will notice your AC turns on and off occasionally when it’s in power saver mode.

Quick Cool Mode

Turning on your AC in this mode will allow you to reach your ideal temperature sooner, which drives your AC to work with maximum effort. This mode is antithetical to power saver mode. If you keep running your AC this way, your electric bill will more than likely rise.

Sleep Mode

We need less cooling during overnight hours. When this mode is on, your AC will increase your thermostat by 0.5 to 1 degree every hour, with a maximum of 2-3 degrees. You will not notice the difference as you sleep. It is such an effective trick to conserve energy without even feeling the comfort difference.

Setting up the AC modes will affect your comfort and your electric bill. It is best to learn what those modes allow you to do with your AC, so you know how to optimize indoor comfort while also saving energy. It is such a shame to ignore those beneficial features.
