The list above features some of the best window ACs that one can consider buying with technical details, features, pros and cons. This list will surely help you to make an informed decision of buying an AC which you need.

Also, below is the buyer’s guide for a better understanding of the characteristics of a good AC with technical reference to the features.

Buyers Guide to Buy the Best Window AC in India

Technical factors must be evaluated before buying an AC or any other electronic appliance. But, not everyone is sound with these technical details, therefore below are the characteristics of a good AC with reference to technical details.

Following are the main technical aspects related to AC.

Ton capacity

Ton capacity or tonnage in layman term of your AC is the cooling capacity your AC holds. Ton refers to the amount of heat one AC can abstract from a certain area or the heat capacity to melt 1 Ton of ice over a day. The ton capacity is equivalent to 12,000 British Thermal Unit or 3.5 Kilowatt unit which is a measurement of heat.

Area of 100 to 150 sq. ft requires 5000 Btu per hour for cooling, 6000 Btu for 150 to 250 sq.ft and respectively increasing Btu with the increasing sq.ft area. The Btu or Ton requirement for cooling also considers various other factors like the number of people in the room and cooling for the number of hours.

To simplify the calculation for standard room sizes in ideal conditions, the Ton capacity you require according to your room size is mentioned below:-

  • Room size up to 80 sq.ft requires a 0.75 ton AC
  • Room size up to 120 sq.ft requires a 1 ton AC
  • Room size up to 190 sq.ft requires a 1.5 ton AC
  • Room size up to 300 sq.ft requires a 2 ton AC

Factors like sunlight, windows, flooring in the room and height of the room also affect the ton requirement for the proper cooling of the space. For the increasing floor, room height and number of windows, calculate sq.ft 50% more than the room size and install AC with the respective ton or multiply ton capacity with multiple ACs.

Energy rating

Energy ratings and labelling on AC are given by the Bureau of Energy Efficiency, commonly known as BEE. The BEE rating or stars labels is the cost-saving potential of the electronic product on energy consumption. Therefore, products with more number of star labelling should be given priority during purchase, as they will give high performance in low consumption of energy.

Air quality

Air conditioner controls the air flow and temperature in your room. The air quality of your room to a greater extent depends on your AC and its filter. ACs with efficient filters or multiple filters of dust and odour from your room. Efficient filters also prevent fungal and bacterial growth in the AC, which keeps the air clean and fresh. AC without efficient filters experiences foul smell due to fungal growth, accumulated dust and other impurities. Therefore, ensure your AC purchase with effective filter and filter clean indicator for effective filtration and timely cleaning of the filters.

Condenser coils

Air conditioners work basically on heat transfer. The process of heat transfer, which sucks hot air of the room and releases cool air gets through the coils. It absorbs heat where the coolant in the coil turns from liquid to gas which ultimately brings the temperature of the air down. This process depends upon the coil and its efficiency to transfer heat. Copper and aluminium coils are available in the market for AC system. Copper coils are preferable due to their heat transfer ability as it is a superior heat conductor when compared to aluminium. The copper coil is repairable, durable, and requires less maintenance, which is quite opposite in the case of aluminium coils. So, always opt for copper coil condenser over aluminium coil condenser in your AC.

Condensers coils with various coatings like blue and gold coating increase the longevity of the coil and should be given preference during purchase. The heat transfer efficiency of copper coils also brings down energy consumption with efficient cooling through better heat transfer.

Installation and maintenance

Perfect installation and proper maintenance is the key to an efficiently working AC. The process of installation must be carried by a professional. Installation involves the proper fitting of your AC in the window of appropriate size and without gaps. The installation also involves proper electrical fitting with the correct Voltage power supply. A well-packed room with sealed windows and doors must be a part of the checklist of proper installation for efficient cooling. Installations sometimes prove to be a headache therefore, always hire professionals for the task and be physically present to avoid mishandling and faulty installation.

Maintenance of your AC through regular check-ups and regular filter cleaning with filter change will give longevity to your AC and efficient working capacity. Filter cleaning at regular intervals and filter change when required is a lot more necessary. It ensures clean air, better cooling, and less power consumption. Regular check on functionality and other leaks and timely repair of the same will help you keep your AC away from dysfunctioning.

Other features

AC manufactures offers various other features apart from basic and important features. Some features add a lot to your AC and some not. Features like a dehumidifier, climate technology, auto restart, auto fan speed, sleep mode, timer, advanced filters, error detect/diagnose the system, and various other quality features are a must look when you buy an AC. These features benefit you and utility of your AC for added comfort of another level.

Advanced technologies for cooling and power consumption like Tonnage, energy rating, features for added comfort, automation in various manual functions, safety measures, quality checks and many other such attributes make your purchase wise to bring a better AC home.

The above list must be in your checklist before buying AC for you. The list features the most important aspects of buying an AC and will surely help you understand AC and its functions with little terminology knowledge. This buyer guide aims at making your AC buying process simpler and less troublesome when you may get confused with technicality.
