LG dual inverter ACs are designed to operate within a specific voltage range, and they typically have an inbuilt stabilizer to protect the AC from voltage fluctuations. The inbuilt stabilizer helps regulate the incoming voltage and ensures that the AC operates safely even if the voltage from the main power supply is not stable.
Adding an external stabilizer is not usually necessary if your LG dual inverter AC already has an inbuilt stabilizer. The inbuilt stabilizer should be able to handle voltage fluctuations within the specified range and provide adequate protection to the AC.
However, if you experience frequent voltage fluctuations in your area that exceed the specified range or if you want to provide an extra layer of protection for your AC, you can consider using an external voltage stabilizer. An external stabilizer can further stabilize the voltage and protect your AC from sudden surges or drops in voltage.
Before deciding whether to install an external stabilizer, it is recommended to consult the manufacturer's guidelines and specifications for your specific LG dual inverter AC model. Additionally, you may also consider seeking advice from a qualified electrician or contacting LG customer support for further assistance. They can provide you with specific recommendations based on your location and the electrical conditions in your area.
