Tips to Buy AC in India – How to Buy Air Conditioners ?

Air conditioners are becoming a basic need for today’s generation. There are different type of Air Conditioners are available in the market with varying features. The features of the ac’s may change according to the user’s requirement. So, this article provides you the tips that will help you buy an Air Conditioner in Indian market that will be suitable for your room or office.



Type of Air Conditioner Unit

First of all, you need to select the type of AC that can be Split / Window / Portable/ Inverter AC. If you are living in a rented house, then it’s better to buy a Window/ Portable AC because its installation is easier than Split AC. Window AC’s are noisy and less expensive compared to Split AC. If you can afford a Split AC then choose it. If you want a less power consuming unit then choose inverter AC’s. They are the best kind of AC for Indian market.

Cooling Capacity

Cooling capacity of an Air Conditioner depends on the size of the room. You need to think about whether you are cooling a single room, a selection of rooms or the entire house. If the air conditioner is too large, it will cool the room, before it has a chance to remove the humidity. This will leave the room with a damp, clammy feeling. If it is too small, the intended room will leave you feeling hot.

Refrigeration ton refers to the quantity of heat a conditioning unit can remove from a room per hours. One ton of air conditioning is 12,000 British thermal unit or BTU and 450- 550 square feet. British Thermal Units per hour (BTU’s per hour) is a measure of cooling power.

Energy efficiency

Efficiency of a room air conditioner is measured by the energy efficiency ratio (EER). The EER is the ratio of the cooling effect measured in BTU per hour divided by the electrical energy input measured in Watts. The higher the EER rating, more efficient will be the air conditioner and also the power used will be less. EER is used to provide ENERGY STAR rating for air conditioners. 5-star rated AC will consume least power compared to a 1 or 3 stars rated AC.

Inverter AC’s saves energy up to 50-30% using variable speed compressor. It has a different star rating compared to other AC’s. Currently most models are in BEE 3, 4 and 5 Star rating ranges on BEE. ISEER is the rating methodology used for inverter air conditioners. ISEER measures energy efficiency of air conditioners based on a weighted average of the performance at outside temperatures between 24 and 43 degree C based on Indian weather data.

If you are using an AC for only few hours then a 3-star rated AC is good enough for you. But if you are using it for more than 8 hours per day, it’s better to buy a 5-star rated AC or Inverter series air conditioners. So power consumption of an AC will depends up on your usage pattern.

Condenser Coil Used

There are two types of condensing coils are present in the market. One is copper and another one is Aluminum. It’s better to buy an AC with copper condenser coil. Copper is expensive than aluminum but its maintenance cost is less and they are easy to available in the market when it get malfunctioned. It is also comes with easy to maintain, superior strength, reliability, and good heat transfer features. Aluminum coils are less expensive and the maintenance cost is high.

Noise from an air conditioner

Inverter air conditioner produces lesser noise compared to other types due to the reason that the compressor motor of the inverter air conditioner does not turn on and off all the time. We can vary the speed of the compressors, delivering precise cooling or heating power as required. Split and Window air conditioners will produce noise because their compressor motor turn on and off when the room temperature changes.

Warranty of the Compressor

When buying an air conditioner always verify the warranty of the compressor. Only buy an air conditioner that has good compressor warranty. Compressors of air conditioners are very expensive, reliable and sturdy devices and they can work for a minimum of 10 years without any problem. But it’s possible that some time for other reason the compressor may get malfunctioned.

Price of Air Conditioner

Price of an air conditioner may depend upon the type of AC, energy efficiency and cooling capacity of the air conditioner. Inverter AC’s are the most expensive AC’s in the market. They consume less power and cooling capacity is good compared to Split and Window AC’s.

Installation requirements

Installation of an air condition unit should be done from an authorised service centre. The performance of an AC will depends on how well it is installed. Window AC comes in a compact size because all the components are packed in a single unit. But split AC has outdoor and indoor unit separately.

After sales services

For an efficient air conditioner you need to service the unit properly. AC performs more efficiently, When an it is serviced regularly. The more efficiently it performs, the less will be electricity.  The company should carry out minimum 4 servicing/overhauling in a year. So make sure the services offered by the company before hand.
