What an AC is

AC or air conditioner is an electric machine that gives you an option to control the temperature of your room according to your wish. You just set a temperature, whether it is more or less than the actual one outside your room, and in a while, you'll get that precise degree of warmth.

The way it works

An AC works in the same method of the refrigerator or fridge in your house, but in a larger extent. The difference is, instead of taking the heat away from the edible objects kept in the fridge, it absorbs the heat from an entire room. Then it reduces the temperature with the help of 'refrigerant'. This chemical substance gets vaporized after absorbing some of the room heat, and the rest of the heat is ventilated through the exhaustion panel of the device. In this way, it helps you to get cozy and chilled out in the burning summer atmosphere. During this cooling process indoor unit produces waste water which drains out. Drain air conditioner water is sign of air conditioner is working properly.

The outside unit consists is a compressor and condenser and inside unit consists blower.Compressor connected to blower by connecting pipe which passes through the wall. Compressor sucks air from outside and made it cool, then passes to the blower. Blower throws out the cold air into the room.

Inverter AC

First of all, Inverter AC doesn’t mean it runs on inverter or it runs even in electricity cuts. It uses an inverter technology, which uses to convert AC current to DC current which further regulate the compressor running speed.

Traditional non-inverter air conditioner compressor motor sometime go “on” and “of”. Whereas, inverter AC compressor is always in “On”state. Although, inverter AC compressor is always on, it saves electricity a lot. When we switch to non-inverter AC, its compressor motor starts running at high speed to cool the room at the desired temperature. After reaching the desired temperature, it stops the compressor motor. When room temperature increases, it starts the compressor again. The compressor is gone “On” and “Off” again and again.

Whereas. The inverter AC compressor motor is always “On”. When the switch on the inverter AC, its compressor motor starts running at high speed to cool the room at the desired temperature. After reaching the desired temperature, it not stops the motor, instead it runs motor with minimal speed so that room temperature constantly maintained at the desired temperature.



When the air conditioner compressor motor goes ‘On’, it consumes peak level electricity. So traditional non-inverter AC whose mother goes ‘On’ and ‘Off’, obviously consumes more electricity. The inverter AC motor is always on so there is no electricity peaks and save electricity a lot. Inverter technology is just like a car accelerator. When compressor needs more power, it gives more power and when compressor needs less power, it gives less power. As inverter AC compressor motor is always on, it controllers the compressor motor speed, electricity consumption based on the room temperature.

Non-inverter AC Inverter AC
Compressor motor always On and Off Always On
Electricity consumption More Less
Reach to desired temperature Takes time Quickly
Appliance lifetime Moderate High
Price Expensive Highly expensive

Overall inverter AC is electricity saving and gives go you quick cooling. Inverter AC is performing better than non-inverter BEE 5 star rating AC.

AC size and capacity

Choosing the right size air conditioner is tricky. Oversized air conditioner cools the room faster than usual, but consumes electricity lot, whereas, undersize air conditioner needs to work hard to cool the room, consumes electricity lot, even though it's not able to cool the room efficiently.

AC capacity depends on the size of the room. Before buying an AC, how to calculate the required AC size by measuring the room square foot area. In India, Air Conditioner size rated in tonnage whereas, in foreign countries they use BTU (British Thermal Unit). Here we summarize the required AC size based on room square foot area.

Room size Required AC size
0 to 80 Sq Ft 0.75 tons
80 to 120 Sq Ft 1 ton
120 to 190 Sq Ft 1.5 ton
190 to 300 Sq Ft 2 ton

Here, we summarize the other factors which are too affecting the Air Conditioner size. For instance, if you are living in a tropical area where temperature in summer exceeds the 40 degree Celsius, windows covering are is more than 25 Sq. Ft. Which allows more sunlight, heat penetrates in the room. In the below table, if any scenario matches, increase the Sq. Ft by 30% while calculating require air conditioner capacity.

  • Room ceiling height more than 10 Sq. Ft
  • Room has multiple windows and windows covers more than 25 Sq. Ft
  • Room situated on the 3rd floor and above or on terrace
  • Summer temperature more than 40 degree celcius
  • AC compressor mounted towards sun direction
  • Room walls directly exposed to sunlight

Aluminium coil Vs Copper coil

In air conditioner coils are used to convert gas refrigerant to liquid refrigerant, vice versa, which further helps to cool the room. Coils can made up of copper or aluminium depending on the manufacturer. Regards aluminium coil vs copper coil, the copper coil has high heat transfer rate, less corrosive, high coil strength. Whereas, only the best thing about the aluminium coil is cheaper, economical than copper coil.

Some necessary tips concerning your air conditioner

  1. Choose the correct size of AC for your room. A larger AC may cool down the room quicker but it will increase the electricity bill. Besides, we mustn't waste away our finite resources, right?

  2. Try to do a little research on the prices. Albeit, we have given you a glimpse of them some minutes ago, it may differ a little bit in different localities.

  3. Wherever you buy your AC from, be it a showroom, you must check your machine thoroughly before you receive it as your own. This will ensure you that there is no flaw in the machine.

  4. If you would like to have a window AC, then make sure that your room has a corresponding size window at a convenient position to put the AC on.

  5. If you prefer a split air AC, you should keep the number of windows of your room in serious consideration. Too much air ventilation may disturb the cooling rate.

  6. As AC's need proper maintenance, you should renew servicing contact provided by the company (in most cases, there has been a 4-times-a- year contact) in due time.

  7. Like most electrical products, your AC should be protected from dust and excessive heat.

  8. If you are going to have an AC for lasting period and private use, try to buy an inverter one. Though it will cost you more, it will give you a longer service. Plus, the window AC's and the split air ones can be swept over by the inverter AC's in the near future.

  9. In order to buy a highly efficient and low energy consuming AC, you should check the EER(Energy Efficiency Ratio) label. BEE provides stars to the ACs according to this label and it ranges from 1 to 5 stars. So that you can easily have an idea about which one will be more convenient for you.
