Your air conditioner has various functions, including a fan to circulate air, which is why your home will get uncomfortable if the AC fan is not spinning. Do you know how to use your air conditioner’s “Fan” mode? Your AC unit’s settings go beyond “Cool” and “Heat”, and using the system’s fan can help you stay more comfortable. In this article, we’ll explain how an AC fan works and provide tips for getting the most out of it.
How AC Fan Mode Works
The fan mode on your air conditioner controls the blower fan. While it doesn’t produce cold air, it helps circulate air throughout your home. You can use the fan while your AC is running or let it run continuously without the system providing additional cool air.
Using the two settings of AC fan mode has the following benefits:
“Auto” Mode
- Reduced energy usage
- Increased dehumidification
- Decreased air duct leakage
“On” Mode
- Fewer hot and cold spots
- Improved indoor air quality
- Reduced strain on the blower fan
Tips for Properly Using AC Fan Mode
Understanding what the fan in your air conditioner does helps to realize when you might need it. These tips can help get the most out of using the system in fan mode:
- Turn Off the Fan When It’s Humid: Running the AC fan when your home is humid can help increase indoor humidity. As air circulates, moisture in it will continue to evaporate.
- Check the Filter Regularly: Even without your AC in cooling mode, the fan will draw air through the filter, which captures dust and allergens. Regular filter checks help avoid indoor air quality concerns.
- Save Power in the Summer: Using the AC fan mode on the hottest days can save power while maintaining a constant room temperature.
- Use the Fan at Night: If your home is cool enough at night, the AC fan can provide a breeze and help you stay comfortable when you sleep.
- Switch the Fan On Earlier in the Day: You can run the fan in the morning, while temperatures are relatively low, to reduce energy consumption. To remove hot air from your home, open windows and doors and keep fan mode on for up to an hour.
- Go Back to Fan Mode After Long Periods of Cooling: If your AC has been in cooling mode for most of the day, switch it to fan mode to help keep your home dry.
Getting the Most Out of Your AC Fan
Using AC fan mode is beneficial when it’s humid outside. In this case, opening windows isn’t going to make you more comfortable. It’ll increase moisture in your home and force your AC to work harder to remove it. An air conditioner fan also works alongside a whole-house dehumidifier to help remove excess humidity via your HVAC ducts. For more adaptability, you can upgrade to a variable-speed AC; the fan and cooling system can run at various levels.
What If My AC Fan Is Not Spinning?
An AC fan not working can point to a fan motor, bearing, or electrical problem. The reasons are typically simpler than if your AC is not blowing cool air. But even if the issue is isolated to the fan, you must call an HVAC company to troubleshoot and fix the problem. Otherwise, your air conditioning system will not work.
Assuming your AC fan is working, you can run it along with a ceiling fan. It can improve comfort even if you raise the thermostat setting by a few degrees. The wind chill effect this produces helps reduce warm spots. Therefore, you can save some energy.
Air conditioner fans and ceiling fans work similarly. An AC fan can deliver a mild cooling effect. Ceiling fans can move more air and provide evaporative cooling. They also tend to use less power than an air conditioner in fan mode.
