Carrier Air Conditioner Modes [Detailed Guide]

Carrier air conditioner modes enable the unit to function in different operating modes such as cool, auto, heat, dry, and fan. They are crucial to know how to identify each one and what it does.

Carrier Air Conditioner Modes Symbols

The symbols that represent the modes of operation in a Carrier air conditioner appear on the display of the remote control. The mode button on the remote does not bear any symbols, so you look into the display to find the symbols. They are pretty much the same as every other mode symbol in other air conditioners, as this article explains in detail.

Carrier Air Conditioner Modes Explained

A Carrier air conditioner has the cool, dry, heat, and auto modes. It also has the Eco and Turbo modes. Each mode causes the air conditioner to function in different ways, according to the temperature needs at specific times.

1. Cool Mode

The Cool operating mode is the most popular one because the primary reason for buying an air conditioner is for cool air. It helps to lower the room temperature whenever the day is hot. Other functions are usually only supplementary at best. Repeatedly press the Mode button until Cool is selected on the remote’s display. 

Ensure you set the temperature to the desired point; that will depend on the temperature outside the house. For the best and fastest results, set it as low as possible. Also, set the fan speed; the higher the speed, the more cool air there is. However, the air conditioner may be noisier than usual if the fan speed is high.

2. Dry Mode

In this mode of operation, the air conditioner mimics a dehumidifier; it removes the humidity in the air while cooling. The air conditioner produces cool air for the room and stops when it reaches the preset temperature. It works best if your home experiences high humidity or there is sensitive equipment you need to protect. You need to be sure of the weather before choosing this operating mode.

Like the Cool operating mode, press the Mode button and watch the remote’s display until the Dry mode is selected. Also, set the temperature you want and allow the air conditioner to run. However, the fan speed remains the same once you set the Dry mode; you cannot adjust the fan speed while the unit is in this mode. It may be best to set the fan speed before selecting the operating mode.

Note: Carrier RV air conditioner Dry mode of operation works in the same way as the Dry mode in other Carrier air conditioners.

3. Auto Mode

This mode of operation automatically adjusts the set temperature and run time of the air conditioner. Typically, you set the temperature and fan speed, then select the Auto mode of operation. After that, the air conditioner takes over when to adjust the fan speed and the functionality of the fan and compressor.

The upside of this operating mode is that it helps conserve energy. In other words, it reduces the unit’s rate of energy consumption. An air conditioner is one of those appliances that consume a high amount of electricity because of the presence of a compressor and fan motors. However, the Auto mode helps regulate that consumption by turning the compressor and fan motors off when the temperature in the room is low enough.

4. Fan Mode

The Fan mode of operation allows only the air conditioner fan to run. In this mode, the compressor does not operate, so there is no cooling function. The fan circulates the air in the room, whether warm or cold. It is best to use it if the room temperature has reached a cool point and you do not need the compressor to run any further. Also, it is ideal for days when the weather is cool and you just need good air circulation.

This operation mode lowers energy consumption because the compressor is off. Since the fan is the only part of the cooling system that is running and it does not consume as much energy as the compressor, the electricity bills significantly drop. Like the other modes, press the Mode button until you select Fan. You can also adjust the fan speed to suit the room’s temperature needs.

5. Heat Mode

The Heat mode of operation is the reverse of the Cool operating mode. When in use, the air conditioner releases warm air in the place of cold. In this mode, the outdoor condensing unit blows out cool air while the indoor unit blows out warm air; in Cool mode, the condenser releases warm air while the indoor air handler releases cool air. Select the operating mode using the Mode button just like the others.

Some air conditioners have both cooling and heating functions. If your air conditioner has a heater, it works best if the outside weather is cold. Adjust the fan speed the same way you would if the cooling function is running.

6. Turbo Mode

This mode is not exactly part of the primary modes of operation in a Carrier air conditioner. However, it speeds up the cooling function and capacity when activated. It has a dedicated button on the remote control; it is not part of the Mode button.

To use the Turbo function, select the Cool operating mode, set the temperature, and adjust the fan speed. Next, press the Turbo button and the compressor and fan pick up speed to cool the room within a shorter time than usual. It reduces the time it takes for the air conditioner to cool a room, which is useful if the weather is especially hot. However, it uses too much much electricity in the process.

7. Eco Mode

This mode is also not part of the basic air conditioner modes of operation. But it helps save energy when the air conditioner runs. In this mode, which has a dedicated button, the air conditioner reduces the run time for both the compressor and fan to conserve energy. 

It does not affect the unit’s efficiency or functionality, only that it automatically turns off the cooling system more frequently. The same is true for the X-Eco mode if that is what is available for your air conditioner.

If a mode of operation does not function as it should, contact the Carrier Service Center or hire a qualified HVAC technician to service the air conditioner. Otherwise, the unit may get damaged beyond repair.

Carrier Air Conditioner Sleep Mode – Meaning

The Sleep mode in a Carrier air conditioner works best at night when you cannot stay awake to regulate the unit’s functionality. Whether it is running on cool or heat, the operation is the same; it automatically increases the set temperature when the outside temperature becomes colder or lowers it when the outside temperature becomes warmer. 

That way, you can sleep comfortably at a suitable room temperature. It also helps to regulate electricity use; the air conditioner does not run at full blast while you sleep, but the compressor switches off and on as needed.

Carrier Air Conditioner Recovery Mode

The recovery mode in a Carrier air conditioner is usually evident on the thermostat. If your air conditioner is connected to a programmable thermostat and it shows ‘Recovery’, it indicates that the unit is working to adjust the room’s temperature. The thermostat goes into the recovery mode when it has been in an energy-saving mode or off for some time. 

When the air conditioner is set to resume regular operations in a new temperature setting, the thermostat displays the mode as it works to lower or raise the temperature in a gradual manner without using too much electricity.


This article is a detailed guide on what Carrier air conditioner modes mean and how to activate them. Each mode of operation has specific functions and manner of activating them. Also, some modes are unique to certain models, so you may want to consult the user manual for the modes in your unit.

You will find the Cool, Dry, Fan, Auto, and Heat modes of operations. Some units also have the Turbo and Eco modes that come in handy when you need fast cooling or want to conserve power use. Always monitor your Carrier air conditioner and how it runs. If any mode does not operate in the correct manner, contact the Carrier Service Center or hire an independent technician for further assistance.
