We are humans and with that said, have different preferences. Some of us like to keep a portable air conditioner. Whereas others intend to have a small convertible air conditioner. In either situation, space is one of the main aspects which makes us select or reject an air conditioner. Likewise, there are other factors that help in deciding which is the best small room air conditioner in 2021. Let’s check on those and then move on to the list of products we have to recommend. 9 Best Small Room AC in India 2021

Guide – Determining Factors to Select Best Small Room Air Conditioner in India 

Besides space, there are several other factors that help in choosing the appropriate cooling machine. In that regard, enlisted are factors to look into before buying an air conditioner for a small room.

Preferred Type 

Four types of air conditioners are available in the market. They are:

  • Multiple split air conditioner: the main difference between a split air conditioner and a multiple split air conditioner is the connection of 2 indoor units with 1 outdoor unit. Along with cooling, they heat 2 to 3 small rooms that are close to each other.
  • Ducted air conditioner: most expensive type of air conditioner that cools a big house easily. More of a central unit bearing many connections, sensors, and air outlets to cool all the rooms of the house. There is a controlling panel that adjusts the temperature according to the needs.
  • Split air conditioners: two parts are attached to the split air conditioners. The first part connects pipes to the indoor unit. The second component is the compressor unit that is mostly outside.  It has the potential to cool two or three small rooms within 60 sq. meters.
  • Fixed on wall or window: cheapest type which is installed on the wall or inside the window. Chills the room that is within 50 sq. meters.

Budget Inducing Elements 

Budget is always inevitable. By the end of the month, you are required to give bills. But what happens before that at the time of selecting the best air conditioner for a small room? We tend to ignore or rather forget to bear these key points in mind. If we keep them in mind we get reduced energy bill.

  • Thermostat: simple logic has to be followed. When the thermostat is high, it needs more power to function and vice versa. That is why it is important to set the thermostat in a reasonable setting.
  • Size: capacity is something that you must keep in mind. To determine the right size, it is better to know the capacity of your house (condo, bungalow, etc.).
  • Economy mode: see this feature in the air conditioner. Merely because it will lessen the electricity bill.

Capacity of Use 

The perfect temperature for any small room is 2.5 kW (kilowatts, the term for measuring temperature capacities). However, slightly bigger rooms or larger rooms require up to 6 kW. It is therefore vital to know the capacity required. So that you don’t end up buying too small or big air conditioners. In this context, you must remember the following points.

  • Climate and how it changes
  • Type and size of the room
  • Measurement and alignment of doors (glass) and windows
  • See if the floor, ceilings, and walls are insulated
  • Also, note if there are curtains on windows

Performance and Mechanism 

Mechanism and performance are those factors that can’t get ignored. The fan speed and motor are some of the things to check. You should select a unit that gives the best and most airflow in different speed (fan’s) settings. 9 Best Small Room AC in India 2021.

Advanced and Exceptional Features 

Other than all that we have mentioned, there are some traits that fall in the unique features. Those are also a must to look at. For example, the compressor system must be reliable and efficient. There should be a built-in accumulator. An alarm to indicate when the tank is full will also assist in making the right decision. Filter that works as a purifier should also help the user. 9 Best Small Room AC in India 2021.
