Why Does the Fan Keep Running on My Air Conditioner?

One of the most common questions we get here at Parley’s PPM Plumbing, Heating & Air Conditioning is “Why does the fan keep running on my air conditioner?” There are a few possible reasons for this, so let’s take a look at each one.

1. The air conditioner is set to “fan only” mode.

   This is the most likely reason if you notice that the fan keeps running even when the compressor is off. In this mode, the air conditioner will run the fan continuously to circulate air throughout your home. You can usually switch out of this mode by pressing the “mode” button on your remote control until it shows the icon for cooling (usually a snowflake).

2. The air conditioner is low on refrigerant.

   If your air conditioner is low on refrigerant, it will run the fan continuously to try and cool the air. This is because the refrigerant is what actually cools the air, so if there isn’t enough of it, the air conditioner can’t do its job properly. If you think this might be the case, it’s best to call a professional for help.

3. There’s something blocking the airflow.

   If there’s something blocking the airflow from your air conditioner (like a piece of furniture), it will cause the unit to work harder than usual. This means that the fan will have to run for longer periods of time to circulate the air properly. If you notice that the fan is running more frequently than usual, it’s worth checking to make sure that there’s nothing blocking the airflow.

4. The air conditioner is turned up too high.

   If you have the temperature on your air conditioner set too high, it will cause the unit to run for longer periods of time to try and reach the desired temperature. This means that the fan will also run for longer periods of time. If you notice that the fan is running constantly, it might be a good idea to turn down the temperature a few degrees.

5. The air filter is dirty.

   A dirty air filter can cause all sorts of problems for your air conditioner, including making the fan run more frequently than usual. This is because a dirty air filter restricts airflow, which means that the unit must work harder to circulate the air. If your fan is running more frequently, check the air filter and see if it needs to be replaced.

These are just a few of the most common reasons why an air conditioner fan might keep running. If you’re still having trouble, it’s best to call a professional for help.
