A voltage stabilizer for AC is designed to automatically maintain a constant voltage level for the load to prevent excessive power fluctuations. So a voltage stabilizer plays a vital role to keep your Air Conditioner safe and also responsible for constant cooling.


In recent times, the increasing demand for electronic appliances has affected electricity circulation. Half of us Indians live in areas where electricity and voltage fluctuations are an issue yet. ‘Accept it and deal with it’ is the attitude we apply. If we invest a hefty amount of money on Air conditioners, why not for safeguarding them.

I understand that Invertor type AC doesn’t need any voltage stabilizer as they have inbuilt one. However, non-invertor type AC needs a voltage stabilizer to keep the electronic parts healthy over the time.

The main function of an AC voltage stabilizer is to find the optimal operating voltage range for your Air conditioner.

Do I Need a Voltage Stabilizers for My AC?

Yes, you definitely need a voltage stabilizer for you AC. To understand this answer, you need to know the fact that there are two kinds of electronic home appliances available in the market.

  1. Resistive Load (appliances without motors)
  2. Inductive Load (appliances with motors)

1. Resistive Load Appliances

All appliances without motors have high voltage operating range. That means they can function from low to high voltage. So basically they don’t need any kind of voltage stabilizer. In low voltage the output of such appliances become less, for example, a bulb will glow less in low voltage. In high voltage, more current will pass through a bulb and thus it glows brighter.

Example of Resistive Load Appliances Are

  • Tubelight, Bulb, Television, Water heater, Induction Cooker, Iron, Water Purifiers, Room Heater

2. Inductive Load Appliances

These appliances work in a limited voltage range. That is why when the voltage drops than the operating voltage range, your AC will not function at all. As a result, more current will flow to your AC’s electronic equipment, and it may damage or burn your AC.

At high voltage, a high current will pass to your AC, result in quick start and then gradually become consistent. However, the initial high current may also burn the AC equipment, right? Consequently, we need a voltage stabilizer to make sure that your AC is running in its operating voltage range.

A ceiling fan also has a motor, but its working voltage range is high. Therefore in the low voltage, your ceiling fan still works but not your AC. So appliances with the motor require a stabilizer, especially the one with the compressor on it or large motor.

Example of Inductive Load Appliances Are

  • Refrigerators, Air conditioner, Water Pump, Washing machine

So let us know if you have any question regarding the topic. We will answer your question specifically.
