Window AC Buyer’s Guide

Indeed, AC machines should be chosen correctly. As people prefer to run a single AC machine for about 6-8 years minimum without changing it. So, most of them demand a durable and long-lasting AC. 

Also, giving an excellent output while consuming less electricity should be the main feature of the machine. It should be budget-friendly also. Considering many factors, it’s indeed difficult to find the correct one according to demand. 

So, we have worked out the equation for you and given you the list and discussed some features.

Some of the factors are mentioned below:

  • CITY/ LOCALITY of Residence 
  • AREA of the ROOM
  • Daily Usage Time
  • MONTHS in a year the AC will be used

The atmosphere of the place of Residence:

Usually, the temperature may be taken as the main point of consideration to select the perfect AC. As every place in India has different temperatures. That is why while buying AC temperature should be kept in mind. Because the temperature in Mumbai is not the same as in Delhi. 

Area of the Room:

Here the area is the volume of the room. And as the size of the room varies, the Tonnage of the AC should be kept in mind. Larger rooms require heavy Therefore, this increases the prices.

Moreover, we provided, 

Preferred values of Room size to capacity

≤ 80 sq. feet à 0.75-ton AC 

10 – 20 sq. feet à 1-ton AC

120 – 190 sq. feet à 1.5-ton AC

190 – 300 sq. feet à 2-ton AC

≥ 300 sq. feet — Installation of 2 AC would be perfect.

Daily usage time and Months in a year the AC will be used:

Certainly, this criterion helps in the calculation of Electricity consumption.

The BEE (Bureau of Energy Efficiency) has identified each AC machine with a star rating. Thereby, this star rating is according to the electricity consumption rate. 

As we know a 5-star machine is the best in this category. But the prices of these machines are very high. But they are the most efficient AC machines.

Aluminium coil vs Copper coil

The materials that are used in several coils like condenser coils, evaporating coils, etc. should be kept in mind. Usually, aluminium or copper coils are used for this purpose. But copper coils are more effective than aluminium. As Copper has high efficiency of heat transfer. On contrary, Aluminum is economically cheaper but provides less efficiency. 

Features you normally encounter in AC:

Anti-bacteria filter:

Modern-day AC machines are provided with Anti-bacterial filters. Whereby, It filters the allergens, pollen, bacteria, etc. in the room.

Dust filter:

As we know, these filters remove the dust in the room. And they should be cleaned at a regular interval. Because the accumulation of this dust may decrease the life span of the AC.


This feature in window ACs helps to remove excess humidity. As humidity can cause sweating. So dehumidifiers help in controlling humidity to make it comfortable.

Auto clean function:

This function keeps a check on the accumulation of bacteria or fungi inside the AC machine. This, as a result, enhances the durability of the machine.


This advanced feature actually helps detect the number of people in the room. Consequently, adjusts the temperature accordingly.

Q4. Does every AC need a stabilizer?

Ans. Usually, a stabilizer helps in voltage fluctuations. And if you have input voltage fluctuations in your area, then a stabilizer is a way out. 

Q5. Does AC consume huge electricity?

Ans. Eventually, the calculation of the consumption of electricity includes the tonnage of the AC, the running time, the speed and many other factors. On average, 1450-watt AC consumes 1.16 units per hour for a fixed-speed AC.
