What to Look for When Purchasing an Air Conditioner

Winters season is over and the weather is already warming up. Its time to prepare for the upcoming scorching hot summer. You can start by cleaning and servicing your cooling appliances (Fans, Coolers, and Air Conditioners)  and if required, purchase a new one while the demand has not picked up and the prices are still low.

Fans and Air Coolers don’t cost much, but air conditioners cost a sizable amount and therefore one must take time in checking features, performance and customer experience of different models before finalizing on the one that you want to purchase.

In this article we will share some important buyer guidelines that you must keep in mind when selecting the best AC in India 2021.

Air Conditioner Buyer Guidelines

Air Conditioner Capacity/Power/Tonnage

This is the most important aspect that one must keep in mind when purchasing an AC. In India, most people buy a 1.5 ton air conditioner without thinking if it would be too weak or too powerful for their actual requirement.

If you buy an under power air conditioner, then it won’t be able to cool your room. Similarly, if you purchase an Air Conditioner which is more powerful than you need, then it will lead to unnecessary addition to the electricity bill. So, its very important that you purchase an AC that is appropriately powered.

Sometimes, even the smart people make a mistake in this aspect. Why? Because the sales men in showrooms and also the product descriptions on the online e-commerce websites simply provide the guidelines like 1 Ton AC is good for rooms under 110 Sq. Ft., 1.5 Ton AC is good for 150 Sq. Ft. room, and 2 ton AC is good for 180 Sq. ft room.

Practically this is not appropriate as several other factors affect the cooling capacity of an AC than just the area of room. For example, a room at the top floor with roof exposed to sunlight would need a more powerful air conditioner than the room of same area at the basement or ground floor. Similarly there are several other factors that should be taken into consideration when deciding the appropriate capacity of Air Conditioner for your room.

We won’t go into details of factors and calculations you need to make because we have a easy solution for this problem. Visit the link below and go the website of General AC where you can input your information like your city, room dimensions, size of windows, number of people usually present in room, etc etc. If your city is not listed, select the one which has similar weather conditions.

Your Budget

Once you have calculated the tonnage of air conditioner required for your room, next you would need to decide on the amount you would like to spend/invest on this important appliance for your home.

To give you an Idea here is an approximate price of different brands for a given capacity of AC

TonnageSplit ACWindow AC
1 Ton AC₹24,000 to ₹32,000₹20,000 to ₹26,000
1.5 Ton AC₹27,000 to ₹60,000₹24,000 to ₹32,000
2 Ton AC₹37,000 to ₹80,000₹28,000 to ₹48,000

This is not all. There are some other expenses that may come during the time of installation. For example, the installation charges for a window AC would be around ₹650 + cost of stabilizer, and MCB/power switch. The cost of installing a Split AC would range between ₹1500 to 2500 + cost of stabilizer (if required), + cost of AC brackets (if required) , and MCB/power switch.

If the distance between installation point of internal unit of AC and outer unit of AC is more than 3 meters, then you would also need to pay extra for the copper wire.

5 Star BEE Rated AC/Electricity Consumption

All appliances these days come with an energy star rating. These ratings tell you the amount of electricity that appliance will consume in an year. In simple terms, a 5 star rated appliance saves the most energy and a lower star rated appliance consumes much more electricity.

Air conditioners or any other appliance that comes with a 5 star BEE rating is usually costlier than its counterpart with lower star rating. This means you will need to shell out more money upfront to purchase an energy saving 5 star rated AC. However, you will save more money in the long run as it would save your electricity bill month after month, for several years.

We recommend that you go for a 5 star rated Air conditioner. Or at least go for a 3 star rated inverter air conditioner.

Service Quality and Availability in your City/Town

Many times people fall for products that are very cheap and apparently offer a great value for money.  In such cases they don’t even care about brand value or check if the product would be serviceable in their city if a problem arises in future. Examples of such brands would be Amazon Basics or Solimo by Amazon, Croma, MarQ by Flipkart, etc.

Similarly, sometimes people are so enthusiastic about purchasing the best machine, that they don’t care if there are no service centers of that company in their city.  For example, General AC makes best air conditioners in India but they have service centers in very limited cities.

We advise our readers to avoid such inclinations and stick with brands that are serviceable in your city. You can check this by searching on google to see if there actually is a service center of that brand in your city.

Many brands, hire local technicians to provide installation service to their customers on company’s behalf. Such technicians are no good and they don’t care much about customers. Services provided by such companies are usually poor.

Know the Features You Need

When you look at or read the features of air conditioners, you will find terms like:

  • 100% copper condenser coil for durability
  • High Ambient Operation
  • Dust Filter
  • Hidden Display and Sleek Design

They sound nice, but they are very basic features and are present in almost all air conditioners. Even in the cheapest ones.

The real features to look for are:

  1. Cooling Capacity: Cooling capacity of an AC is listed in Watts or BTU on the Energy Star Rating label pasted on the product. Compare it with the rating of other models.
  2. Inverter Technology: Prefer purchasing an AC with inverter technology as it not only saves electricity but also provides stable temperature inside the room. This type of AC never shuts down its compressor but operates it at variable speeds to maintain the temperature of room.
  3. Hydrophillic Coating: Look for air conditioners that come with Bluefin or goldfin or other hydrophillic coating on evaporator. Such coatings increase the life of air conditioner.
  4. Quick Cooling Capacity: High end air conditioners come with dual/twin rotary compressor and  specially designed evaporators (Usually made of Alloy and not Copper) to quickly absorb the heat inside the room. Such air conditioners cool the room very quickly and provide immediate relief from the heat.

Bottom Line

Air conditioners last for several years, and therefore buy the one that will be durable, less power consuming, and backed with a great service network from a Brand that has been around for some years.
