Buying Guide to a Stabilizer

1. Mounting

Wall mounting an electric based appliance is probably the best thing to do. Placing them on a table or the ground could be risky and endangering. These are often placed on a higher level, and preferably they are wall-mounted to protect from getting electric shock.

2. Indicator

Indicators work to inform about how much electricity supply is required. These indicate the stabilizer, which often cuts the supply off in order to save the appliance when frequent fluctuations occur. 


During power cuts, we often see fluctuations and high low voltage, which may lead to internal and severe damage to the compressor and the appliance. ITDS or initial time-delay system helps by enabling a time-lapse during which it gives time to the compressor gets required supply and is balanced 

4. Overload protection

The stabilizer has built-in protection with which it turns itself off by cutting the power supply. 

In case of short circuit or burnout, due to overload leads to internal damage and harm to the appliance as well.

Stabilizers for ACs come with a warranty of 5 years of period. This allows you to enjoy a more extended period of time with AC and compressor performance and cooling. It is recommended to choose an AC stabilizer that is crafted particularly for your home air conditioner. There are a variety of stabilizers available, and remember to select the one for AC.

Stabilizers have a variety of load capabilities, and it varies as per the fluctuations, power supply, and weightage of your Air conditioner.


1. Is a stabilizer essential for the Air conditioner?

Air conditioners and similar appliances need a stabilizer, especially when there are frequent fluctuations, as these high and low fluctuations can damage the internal system. The stabilizer helps by consuming excessive power.

2. What is the cost of the stabilizer for the air conditioner?

A good stabilizer for an air conditioner starts from 1300 and can go high depending on the brand, quality, features, and functions it offers

3. Can an air conditioner work without a stabilizer?

Normally, you would need a stabilizer since there are fluctuations often. But if your area has a stable power supply, you can then easily use your AC without any stabilizer. 

4. Is a stabilizer necessary for inverter ACs?

Inverter air conditioners do not need a stabilizer as these ACs come with a built-in stabilizer. Such stabilizers cut off the power supply whenever it finds frequent fluctuations.
