Temperatures rising in India have caused air cooling (AC) more or less essential for all households. But, choosing the wrong AC for your home can cause significant electricity costs or the regret of buying an AC that’s not very effective in cooling your space. It’s crucial to get the correct information prior to going to a shop to purchase one. This buying guide will guide you through the various aspects that you must be aware of so that you can choose the home air con system to avoid the heat of summer.

What kind of AC is best to buy?

Windows and split air conditioners are two of the most well-known types of ACs used in homes. They have identical features but are available in various sizes. Due to their size and construction, they have distinct advantages and disadvantages of each one.

Air conditioners for windows are among the most popular single-room air conditioners. The entire components of the AC are integrated in a single unit. Therefore, window ACs are much simpler to set up in comparison to ACs split. They’re typically placed on a window sill or a hole within the wall. However, the fact that the components are operating in the same box means they’re louder than split air conditioners. They’re the most suitable option for small rooms and are priced to be reasonably priced.

Split ACs as the name suggests, are two units. The indoor unit is located inside the house, and the outdoor unit is placed outside. Since the compressor is located within the outside unit split ACs can be quieter than window ACs. Split ACs make it challenging to set up the AC because you need to cut holes in the wall to connect the tubes and cables connecting to the units. They can be put in rooms with no windows and offer a convenience that window ACs can’t offer. They’re sleek and come in stunning styles that are designed to be a part of your home. They’re slightly higher over window ACs but.

What capacity is appropriate for your space?

Once you’ve decided about the kind of AC it is important to find out what capacity is available for the AC. Air conditioner capacity is measured in terms of tons. Window and split ACs are available in a variety of capacities, which range between 1 and 2 tons. Tonnage in an AC is not a reference to its weight but that determines the speed at the rate at which it AC can cool the room. Simply speaking, a bigger area will require an air conditioner with greater tonnage.

A reliable method of determining the capacity needed is by taking into account the concept of BTU (British Thermal Unit). The higher the BTU greater the cooling capacity of an air conditioner. The weight of a single car is estimated at 12000 BTU. In accordance with international standards, it’s believed that you will require around 20 BTU per square. feet. The number could also vary according to the temperature of the room, as well as other variables. A larger tonnage indicates that the AC could be costlier, however, the cost of an AC could also vary based on its characteristics and energy efficiency.

The dimensions of the room are the primary factor to take into consideration when determining the amount of tonnage but there are other elements that need some consideration. For instance, the size of the windows, as well as the amount of sunlight entering the space, also need to be considered. It’s crucial, especially in the summer months, since sunlight entering the room could also increase the temperature considerably. In the same way, the number of light fixtures in the room will also make an impact. The more electronic appliances running in the room may raise the temperature significantly.

What is the best way to choose the most efficient AC according to your needs?

One of the main reasons why people steer against purchasing one is its operating cost. The effectiveness of an air conditioner was earlier referred to by the term EER (Energy Efficiency Ratio) but as temperatures across India fluctuate throughout the year the new standard was introduced in the form of ISEER (Indian Seasonal Energy Efficient Ratio). It’s the ratio of an air conditioner’s capacity to cool (BTU or Tonnage) to its power consumption total. The ISEER ratings are usually referred to as stars, which can allow you to identify energy-efficient air conditioners. The higher stars, the higher the energy efficiency of the air conditioner. If you’d like to learn more details regarding ISEER ratings and their importance of them be sure to read our post on it.

ACs with similar capacities do not have to use the same amount of power. Certain ACs have an ISEER rating that is higher than other models. However, they can be costly. In these instances, it is crucial to consider whether purchasing the more costly but more efficient model is the right choice.


Beyond the power consumption and capacity, there are many other aspects to think about. One of the most crucial aspects to look out for is the type and quantity of air filters that are used in air conditioning units. Many manufacturers now offer anti-bacterial filters to help clean the air of germs and bacteria so that you can create an environment that is safe for everyone. Certain air conditioners also come with Odour removal filters.


Nearly every air conditioner of is equipped with flaps that are manually relocated to divert air. Certain models offer the option of using a remote that can be used to automatically regulate the direction of airflow.

Other characteristics:

It is also possible to purchase an AC which comes with a remote with an electronic display. This is helpful in controlling the various options. For instance, it can help by using the timer feature which allows you to turn off and on the AC according to your preferences. The level of noise from the AC should be considered particularly if you plan for it to be installed in the bedroom. The levels of noise from an air conditioner are typically listed in the specification.
