Air conditioners have become essential for comfortable living, especially in regions that face extreme temperatures and unstable power supply. While modern ACs are designed with advanced features to enhance performance and reduce energy consumption, they are still highly vulnerable to one major threat, voltage fluctuations. When the voltage drops too low or spikes too high, the most affected component is the AC compressor. Since the compressor is the heart of the air-conditioning system and also the most expensive part to repair or replace, protecting it becomes a crucial priority. This is where AC stabilizers play a vital role.
