☑ Types of AC Available in India

1. Window AC

Window AC is a single unit that contains compressors, connecting pipes, heat exchangers and motors. Window AC can only be installed on window of a room.

Advantage of Window AC:

  • Smaller in size
  • Low cost compared to split AC
  • Easy to install on a small window
  • Doesn’t take up floor space in your room
  • You don’t have to drill the wall
  • Most of the AC brand offer built in heater in window AC, so you can use that in winter season
  • Easily movable from one place to another
  • Perfect for supplemental cooling
  • Perfect for tenants who change their house frequently

Disadvantage of Window AC:

  • The noise level a bit higher when switched on
  • Security concerns may arise in some cases
  • Installation is difficult if there is no exterior support


2. Split AC

Split AC consists of two units, an indoor unit (blower) inside the room and an outdoor unit (Compressor + Condenser) that stays outside the house. Both air condition units are connected with pipe.

Advantage of Split AC:

  • Doesn’t require window for installation
  • Can be installed on any wall, preferably a wall that has an outside facing.
  • Fast cooling
  • Some models comes with heater
  • Provides climate control in the room
  • Almost no noise while running
  • It adds good look in the room

Disadvantage of Split AC:

  • Split ACs are usually expensive than window AC
  • Moving split AC is not easy
  • Requires bigger space than window AC
  • Sometimes requires long tube to connect both units
  • Maintenance cost is higher


3. Portable AC

As the name suggest, portable air conditioner is a moveable AC that gives you the flexibility to move the AC anywhere such as bedrooms, computer rooms, garages, drawing room etc.

It is a great solution for small houses and those who can’t afford AC in every room. Also, where centralized AC can’t be installed, portable AC is a great option.

Advantage of Portable AC:

  • You can move portable AC anywhere in the house
  • It doesn’t require wall mount installation
  • Cost effective compared to other ACs
  • Fast cooling
  • Smaller in size, takes up less space
  • Available in several models and brands
  • Many models provide carbon dust filter and energy saving feature

Disadvantage of Portable AC:

  • A bit noisy
  • Condensate water management is difficult
  • Some model comes with full self evaporation of water but those models are expensive

4. Inverter AC

Inverter AC is the best air conditioner system among all options. This type of AC has an inverter that controls the speed of compressor motor.

In normal ACs, the compressor runs at a regular speed while an inverter AC uses a variable speed compressor. The AC sensor can measure the temperature of the room and adjust the speed of the AC compressor.

This way an inverter AC can provide better energy efficiency and cooling performance.

Advantage of Inverter AC:

  • Better cooling with less power consumption
  • Better life of AC components
  • Built-in inverter adjust the power supply, thus no fluctuation in electricity

Disadvantage of Inverter AC:

  • Repair is expensive
  • More expensive than normal ACs
  • Require specialist technician to solve the issues of AC

Humble Request: Please plant trees to eliminate global warming.

☑ Purchase AC by Cooling Capacity

Cooling capacity is probably the foremost thing that you should consider while purchasing an AC in India. Be it window AC, portable AC, Split AC, whichever air conditioner you buy, you need to check how much capacity would be enough for your room to cool.

But how can you calculate it. If you are into math, you can refer to this formula:

AC capacity = (sqrt*(room floor size))/10

*Sqrt= Square root

For example, let’s assume your room floor size is 150 sq feet

AC capacity = (sqrt*(150))/10

Square root of 150 is 12.247

AC capacity = 12.247/10 = 1.2

So you need 1.2 ton AC for your 150 sq feet room.

If you don’t want to put load on your head, check the table below that explains how much AC capacity is required for different room size.

Room Floor SizeAC Capacity
120 to 140 Sq. ft.1 ton
150 to 180 Sq. ft.1.5 ton
180 to 240 Sq. ft.2 ton

☑ Purchase AC by Power Consumption (BEE Rating 2018)

All air conditioners in India are star rated by Bureau of Energy Efficiency (BEE). This organization rates AC on the basis of cooling amount per electricity watt consumption.

You should buy a higher EER rating air conditioner because higher star rating AC provides more energy efficiency, less star rating provide less energy efficiency.

BEE rating 2018

In 2018, Bureau of Energy Efficiency (BEE) introduced a new rating system for Air Conditioners. In this system, 2 energy rating point are dropped for non-inverter split ACs.

For example: Any non-inverter split AC that was rated 5 star in 2017 is now rated 3 star in 2018. So, you can see the difference between old and new rating system by BEE. Thus, it is important that you buy AC according to the 2018 BEE rating system.

☑ How Much Electricity an AC Will Consume?

Whenever someone thinks of buying an AC, this question certainly pops up in their mind.

Of course, you should be concerned about electricity consumption of the AC, after all you will have to pay the bill through your hard earned money.

To help you here, I have a simple formula that will tell you how much electricity an AC will consume.

Note: This formula is used only as an example that will give you an idea about the approximate electricity consumption. Actual amount may vary slightly.

Electricity Units = Input Power in Watts * Time in hours / 1000

To know the input power you can either check on the box of the AC or the back panel of the AC.

input watts ac

So here in this example picture of 1.5 ton Godrej split AC, the input power is 1351.

So, if we apply the formula then

Electricity Units = 1351 * 1 hour / 1000

Electricity Units = 1.3 Units/hour

Let’s assume the electricity rate is Rs. 7/unit.

So, 1.3 * 7 = Rs. 9.45 per hour

If you run your AC 9 hours a day then:

9.45 * 9 = Rs. 85/day Approx

A fact you should know: The compressor of your AC is not always on, when room temperature reaches a certain level, it shuts down. When the temperature of room changes up or down from the certain level, compressor starts working again. So, you can say that the compressor will be turned off for 30-35% of the total running time of the AC.

Another fact, you don’t always get 230V power supply constantly, so the actual power consumption may vary.

Considering both facts, you can subtract 20% – 30% amount from the total AC consumption.

So, 20% of Rs. 85,

20/100 * 85 = Rs. 17

So, you should deduct Rs. 17 from 85.

That means 85 – 17 = Rs. 68/Day

So, Rs. 68/Day might be the actual power consumption of your AC.

Based on above calculation you can easily get an idea of what your AC would consume and how much you have to pay for the electricity.
