There is a wide array of air conditioner brands, each offering numerous models that differ primarily in aesthetics, design, appearance, colour, shape, and size. As a result, selecting the most suitable air conditioner can be a daunting task for consumers. Additionally, it is crucial to consider the latest models when making a purchase. The key factors to focus on while choosing the right AC include its energy efficiency ratio, power consumption, cooling capacity, and any unique features it may offer.

A major deciding factor for consumers is whether you want a window AC or a split AC model or latest Inverter Type AC (variable speeds). Though window units are cheaper and easy to install, split ACs are quieter, aesthetically more pleasing and provide better air distribution. But if there is a good provision for installing window category, go for window only. Globally windows ACs have almost gone out of production but in India we still have a good choice. Once you have decided to buy an air conditioner then a careful market study is required for which Consumer Voice has done some basic research.

Window air conditioners are quite popular because of their lower initial cost, compactness (single unit) and efficiency and ideal for small size rooms, bedrooms, small offices where provision of windows are already there to accommodate the unit. Window AC units are self-contained, single-unit air conditioners that are mounted inside an open window. Split type AC is very popular because it can be fitted in a room without having open up walls or windows to install AC. Split air conditioners are made up of two parts – an indoor unit and an outdoor unit that work together to cool the room. Usually, Split ACs are faster at cooling, more energy efficient and quieter than window AC. Split air conditioners for domestic & small offices use come in the cooling capacity ranging from 0.75 to 3.0 tons.

Room Size and Tonnage of Window AC 

Tonnage refers to the cooling capacity of the air conditioning system, where one ton is defined as the amount of heat required to melt one ton of ice in 24 hours. It is essential to choose an air conditioner with the right tonnage according to the size of your room.

Type – Split or Window

Window ACs are usually cheaper and relatively easier to install, however, they are much noisier as compared to a split AC. Split ACs provide better air distribution, are more beautiful to look at, and provide comparatively faster cooling. Additionally, split ACs provide higher efficiency and are more suitable for long-term use. Both types of air conditioners are available in a large variety of designs and sizes.

Important Criteria for Buying an Air Conditioner

Capacity: The capacity of the air conditioner should be considered depending on the floor size of the room for which the AC is required. A rough measure is that an area in range of 120 ~140 Sq. ft. area will need 1 ton, 150 ~180 Sq. ft. area will need 1.5 ton and 180 ~240 Sq. ft. area will need a 2 ton cooling capacity air conditioner.

Energy efficiency: Air conditioners come with star rated energy efficiency ratings, which has been implemented by the Bureau of Energy Efficiency (BEE). Therefore, any unit with more stars will consume lesser electricity than one with a lower star rating. If the regular usage of ACs are more than 4 hrs/day, go for higher star rated (4-5) AC, else 3 star can serve your purpose. 3-star ACs are most popular as mid-range power saving gives consumers a great price advantage as compared to a 5 star.

Copper VS Aluminium Coils: In recent years, air conditioners have been introduced with aluminium coils for their condenser units, offering a slightly lower cost but reduced durability over time. Therefore, it is highly recommended to prioritize air conditioners with copper coils and not compromise on cost when making a purchase. Copper coil ACs boast significantly longer lifespans and are associated with fewer leakage complaints, making them a more reliable and worthwhile investment.

Installation & cartage: Window air conditioners are so simple to install that even a person without much skill can do it. While placing order clear terms of payment (cash or cheque/draft), installation charges if any as it is generally included in the unit cost. Also insist for the free home delivery while placing the order.

After sales services: Look for a longer service oriented reputed brands which has the capabilities and good network to meet the servicing need of your product. Ask your friends and relatives for feedback.

Brand Selection: You should carefully choose an air conditioner brand which fulfils your need of maximum energy saving through highest EER, best cooling performance and extensive after sales service.

ISEER: ISEER stands for Indian Seasonal Energy Efficiency Ratio. It is the ratio of total annual amount of heat that the equipment can remove from the indoor air when operated for cooling in active mode to the total annual amount of energy consumed by the equipment during the same period. Higher ISEER rating means a more energy-efficient air conditioner that can help you save on your energy bills in the long run.

Cooling Capacity: Cooling capacity is the measure of a cooling system’s ability to remove heat.

Power consumption: Electrical energy over time supplied to operate an electrical appliance.
