5 Questions to Ask While Buying an AC
Community Manager

What comes to your mind when you think of a perfect summer? Relishing a delicious ice-cream, refreshing yourself with some chilled juice or beer (for those who like it), and most importantly lazing comfortably in your home, with an air conditioner that keeps you relaxed throughout summer. As an air-conditioner is proves to be not just an expense, but an investment for you, your home, your family. So rather than reading the scheme related documents carefully before investing, we want to ensure you ask the right questions to any store executive after your research online.


So let’s begin: Here are five questions that you must ask when buying an AC.



1. Does this AC use Copper or Aluminium coils? What about the condenser?


An exchange of heat takes place through the coils leading to a cooler room. Therefore, the metal of the coil and its heating transfer characteristics pretty much defines the efficiency of cooling. You would see two major types of coils & condensers in market, Copper & Aluminium; both with their unique sets of benefits.

Let’s observe for Copper first:


  1. 1. Copper is a better heat exchanger than Aluminium and therefore, is more cooling and energy efficient.
  2. 2. Copper coils are stronger, far more reliable and are also easier to repair.
  3. 3. Copper passes the test in hot and humid areas too, since corrosion is no concern.

Aluminium has its upside too:


  1. 1. An AC with an Aluminium coil won’t pinch your wallet as much as the one with copper coils.
  2. 2. If you aren’t one of those coping with the sea-breeze, an aluminium coil could last you as long as the copper ones.
  3. 3. Some brands have now started providing a 5 Year Warranty on the coils to make the Aluminium coils last as long as the Copper alternative.

In sum, Aluminium coils and condensers may make the price tag of the AC look attractive, but electricity consumption and longevity considered, an AC with a copper condenser & coil, is definitely a recommendation.


2. What Gas does the AC use?


The duty of the Gas(R-22 / R32 / R410A) is to absorb and release heat efficiently so that the compressor can run cooler reducing the risk of overheating and burn-out of your Air Conditioner.

R410A should be your choice. Here is why:


  1. 1. It not only is more energy efficient but has the ability to perform at higher pressures thus, being able to handle greater temperatures.
  2. 2. It is non-inflammable gas, making your Air Conditioner and your home a safer place.
  3. 3. It is a hydro-fluorocarbon (HFC) and does lead to ozone depletion.

However, some of the leading brands today are using the R32 gas and are servicing their products very efficiently and will ensure you don’t lose the ‘chill’ you need in your room with no major cost difference.


3. What is the EER rating?


The Energy Efficiency Ratio (EER) rating of an AC, represents how efficiently electricity is used. A higher rating signifies that the AC uses electricity more efficiently but it not the actual level of electricity consumption. So for instance, the EER for two Air Conditioners ( 1Ton and 1.5Ton) may be 3.48, this does not imply that they use the same amount of electricity.

Moreover, the calculation of EER has gone through many changes. Notably, 3.48 of 2016 is more efficient than a 3.48 of 2015. Watch out for the inverter ACs which are now rated as per the new ISEER norms of 2018. They will definitely be priced on the higher side, but are guaranteed a more cost-efficient option when you add up your electricity costs.


But Remember, your mantra for buying an AC – latest model (year) with higher EER has to be your pick!


4. Does it have a 4-way swing for quicker cooling?


A four-way swing function in an AC provides quicker and more efficient cooling for a room. By offering the ability to control which way the air-flow is diverted, you can direct the cool air right towards you! Today AC’s allow you to choose from vertical, horizontal, fixed or a custom air-flow. Not only does this make more sense economically, as less energy is spent to reduce the room’s temperature, but also it allows you to relax quicker away from the burning summer heat!


5. What is the standard installation procedure?


If you purchase a split AC, the installation procedure is extremely crucial. When done correctly, the AC can provide optimal cooling and function efficiently. However, if it is incorrectly installed, the AC can frequently develop issues and will not deliver proper cooling. When your new AC is being installed, take care of these six factors; the strength of the wall, proper spacing between the AC and wall, correct height from the ground, accurate tilt of the indoor unit, proper location and placement of the outdoor unit, and correct distance between the outdoor and indoor units.

Brands would promise you a Standard Installation FREE when you buy the AC, but make sure you read the inclusions and exclusions. What you land up paying for the AC finally after the installation may leave you with a not-so pleasant surprise.
