The remote control is an essential component of air conditioners. It allows you to turn the device on and off, select modes, adjust temperature, and set timers. However, what do you do if the remote is lost, runs out of battery, or malfunctions? Are there ways to operate the air conditioner without it?
How to Operate Your Air Conditioner Without a Remote
- Use the power button on the indoor unit
The indoor unit (evaporator) of your air conditioner should have a power button to turn the device on and off. This button is usually located on the front or side of the unit. Look for a circular button with a line inside it, which indicates the power symbol. Press this button to turn the air conditioner on or off. Note that this method only allows you to turn the device on and off, without the ability to adjust modes or temperature.
- Look for a reset or auto mode button
Some air conditioner models have a “Reset” or “Auto” button on the indoor unit. By pressing this button, you can activate the machine in auto mode. Typically, this button is located near the power button and is designed to set the air conditioner to default settings, such as a temperature of 25-26°C and a basic cooling mode. To use this feature, press and hold the “Auto” button for a few seconds or follow the instructions provided on the unit or in the user manual. Keep in mind that this method will only allow you to set the air conditioner to a default temperature, without the option to adjust multiple modes.

- Use your smartphone as a remote
Many modern smartphones support Wi-Fi connectivity and can be used to control your air conditioner through a dedicated app. Download the official app of your air conditioner brand from Google Play or the App Store and follow the instructions provided. Usually, you will need to connect to the air conditioner’s Wi-Fi, log into the app, and follow the steps to connect your phone to the air conditioner. Once connected, you can turn the device on and off, select modes, and adjust the temperature directly from the app, just like you would with a remote control.
- Use a universal remote control
Universal remote controls are available as a replacement for your original remote control in case it is lost or damaged. These remotes are compatible with various air conditioner brands. To use them, you will need to input the corresponding code for your air conditioner brand and model (usually provided in the user manual of the universal remote). Once set up, you can use the universal remote just like the original one to turn the device on and off, adjust the temperature, and access other features.
Some tips for using your air conditioner efficiently:
- Set an appropriate temperature
It is recommended to set your air conditioner temperature between 25-26 degrees Celsius. This range provides a comfortable cooling effect while also being energy-efficient. Lower temperatures will cause the air conditioner to consume more electricity.
- Combine the use of the air conditioner with a fan
Using a fan along with your air conditioner can help speed up the cooling process in the room. The fan circulates the cool air more quickly, spreading it throughout the room. You only need to use the fan for the first 15 minutes after turning on the air conditioner. Once the room is cool enough, turn off the fan to save energy.
- Regularly clean the air conditioner
Air conditioners have air filters that need to be cleaned regularly to remove dust and prevent bacterial growth. Dust accumulation on the filters can reduce the efficiency of the air conditioner and affect its cooling performance. Make sure to include this in your regular maintenance routine.
Now you know how to operate your air conditioner even without the remote control. Keep these tips in mind to stay cool and comfortable during hot days.
