Air Conditioner Buying Guide! Comments 0 March 13, 2018

The rising summer heat makes split ACs more a necessity than a luxury nowadays. Practically everyone has at least one AC at home, and it’s when you finally think of getting one for your home, that you realize that there are so many options and types of split ACs available. You, in fact, find it difficult choosing between brands like Mitsubishi, Onida and Daikin, and also the features offered by them. So here are some tips to help you make the right choice.

1. Budget:

This is the first consideration you need to bear in mind to ensure you buy an AC you can afford. Split air conditioners can cost anywhere between a few thousand rupees to a few lakhs, depending on its size, compressor and features.

2. Types of split ACs.

There are four types of split ACs to select from:

  • Wall mounted is best if you have small rooms that need uniform cooling. Its indoor unit remains in the place while its duct isn’t concealed. Floor mounted or vertical split AC is not famous for homes. They are quite expensive and better for rooms where Wall mounting is not possible. Ceiling mounted or concealed split ACs look good as its unit is hidden. But they are not only expensive; they need a false ceiling for installation.
  • Multi-split ACs have various indoor units connected to an outdoor unit. You can use the units individually or together. However, if used together, the ACS capacity ends up divided. Though expensive to buy, they are relatively a cheaper option than buying two split AC units for a room.

3. Cooling capacity:

The cooling capacity is the one feature that determines the AC’s rate and is calculated based on its tonnage. The split AC’s cooling capacity depends on various factors. You need a unit with a higher and better cooling capacity to cool bigger rooms, if there will be more people in the room and if the outdoor temperature is high.

4. Noise:

It’s apparently better to buy split ACs which produces minimal noise so that they won’t disturb you much, especially at nights.

5. Additional costs:

You should realise that you should not only consider the AC’s rate while considering your budget. There are also additional costs you have to bear after buying a split AC like installation, power and maintenance costs.

6. Energy efficiency rating (EER) :

EER is the ratio of the split AC’s cooling capacity to its power consumption where units with a higher EER are a better buy. These models may be expensive but save money in the long run by consuming less energy.

7. Compressor type:

Compressors are essential parts of the AC as it cools and improves the AC’s performance by circulating the refrigerant through the AC.

There are three types of compressors:

1. Reciprocating compressor:

ACs with this compressor is cheaper but noisier than other ACs. They are a better buy for higher capacity cooling ACs that will be used extensively.

2. Rotary compressor:

These compressors are better but more expensive than reciprocating compressors. They, however, do reduce the loss of pressure in the refrigerator gas. They also require less maintenance, and are more compact and work better and longer. They are better for less than 3 ton AC with minimal usage.

iii. Scroll compressor:

These compressors exist in ACs with more than 2.5 ton of cooling capacity with low sound, economical use and high operating voltage. They are however uncommon with home ACs.

Additional features:

There are additional features to consider before buying your split AC like: Timers are useful if you want to switch off the AC after a few hours’ use. Today’s smart ACs can also be programmed to switch the AC on or off in your absence. You need an AC with an auto restart feature if you have frequent power cuts or tend to switch off the unit regularly. Auto restart automatically starts the AC at the original power upon restoring power. A deodorising filter is a Welcome feature in the split AC to keep the room fresh and odour free from bad smells like tobacco and kitchen smoke smell. The body should have an anti-corrosion coating to reduce corrosion and thus prolong the split AC’s life. Electrostatic filters attract dust and are used for removing dust particles. They thus prolong the AC’s life by keeping it clean. An antibacterial filter helps keep allergens and bacteria out, and the latest models even remind you to change the filter.

  • A remote control proves handy for switching the AC on and offer and even monitoring temperatures without getting up. The latest smart ACs don’t also need you to point the remote at the AC while making changes. Unlike other ACs that use infra-red technology and need a line of sight to work, these ACs use ZigBee technology to control the AC even if you aren’t around.
  • An efficiency meter is a new feature in the latest split ACs which displays actual information about your AC’s energy consumption. You can use the information to control your AC’s energy consumption.
  • Some split air conditioners have sensors that are so sensitive that they detect even the smallest human movements. They then direct airflow in the direction of this action at the press of a remote button. Some models also have a lock feature where you can lock your settings so that no one can change and misuse your AC when you aren’t around. There are also ACs with a heating mode to use in winters. There are also ACs with in-built stabilisers that ensure the AC works well even in extreme voltage fluctuations by regulating voltage stability.
  • Some units also have an auto clean feature where its fan keeps running even after you switch the AC off. This keeps things dry and odour-free by preventing the spread of germs and reducing the formation of fungus and mould on moist parts. It also reduces any foul smell when the AC is turned on the next time. Now that you know what features you need and should look out for, you should find it much easier to find the perfect split air conditioner for your home and your budget
