It is generally not recommended to switch off an air conditioner directly using the mains power switch (also known as the circuit breaker) instead of using the on-off button on the AC remote. The primary reason for this is that abruptly cutting off power to the air conditioner can cause some issues:
Electrical Stress: Turning off the AC through the mains power switch can subject the electrical components to sudden stress, especially if the compressor is actively running. Frequent abrupt power cuts can lead to premature wear and tear on the AC's internal components, potentially reducing its lifespan.
Compressor Damage: The compressor is a critical component in an air conditioner. Switching off the AC through the mains switch while the compressor is running can cause the refrigerant to become trapped in the compressor. This can lead to pressure buildup and potential damage to the compressor over time.
Electrical Surges: Sudden power cuts can sometimes result in electrical surges when the AC is switched off, which might adversely affect the electronic control board or other sensitive components of the AC.
The recommended way to turn off the air conditioner is to use the dedicated on-off button on the AC remote control. This allows the AC to go through its proper shut-down sequence, which helps protect its components and ensures a smoother start-up the next time you use it.
If you want to turn off the AC completely, you can use the remote control's on-off button and then switch off the mains power after the AC has properly shut down. This approach ensures a safer and more controlled shutdown process for the air conditioner.
Remember that regular maintenance, such as cleaning the air filters and scheduling periodic service checks by a professional, can help keep your AC running efficiently and extend its lifespan.
