Benefits of Air Conditioners

Here we have listed the top 3 benefits of air conditioners and these benefits will tell you how much air conditioners are important for your home.

1. Reduced Possibility Of Asthma Attacks

Did you know that having an air conditioner in your home can reduce the possibility of asthma attacks? Well according to Mayo Clinic, air conditioners can easily lower the amount of airborne outdoor allergens such as pollen, mold, mildew, and other allergens. And if you use air conditioners inside your home, then it can also lower your exposure to indoor allergens, like dust mites.

2. A More Secure Home

Usually, when you air condition your home you keep our windows and doors closed. And this generally leads to added security as it is much harder for someone to break in your home with your windows and doors closed and locked than having them open to cool your home.

3. Reduces The Risk Of Dehydration

Lower Temperature directly tends to less sweating. And most people don’t even know that while sweating we are losing a large percentage of water from our body. So it is important to keep your body hydrated whenever you are out in extreme conditions. This risk of dehydration can easily be avoided through some air conditioning

Frequently Asked Questions (FAQs)

An air conditioner is one of the most costly Home Appliances and we should avoid making any wrong decision while purchasing a new one.

That is why we have tried to answer the most frequently asked questions (FAQs) that might help you.

What is Air Conditioner?

An air conditioner is a machine or a system that can easily treat the air in a defined, usually enclosed area via a refrigeration cycle through which warm air is completely replaced with the cooler air.

What to look for while buying an air conditioner (AC)?

There are a lot of things that you need to consider before purchasing an AC unit.

Most often, the first thing you should look for is your room size.

Secondly, try to go on an excellent star rated AC according to your budget.

Better the BEE Star rating in AC means you get more cooling and your monthly bill remains less.

You can read our full buying guide from here, and it will definitely help you with your selection.

Which AC brand is best in India in 2020?

The best AC Brands should be picked according to their performance, innovations, power savings capacity, and after-sales support. 

Considering these factors currently, Hitachi, Voltas, Daikin, and Carrier ACs are ideal options.

However, other manufacturers are also improving their product and service quality every year.

If you want to know about the ranking of these AC brands, check here.

Which type of AC should I buy, Window AC or Split AC?

Before you select the type of AC, please read this carefully. 

In the case of efficiency, Split ACs are way more efficient and versatile as compared with Window ACs.

A 5 star split AC can preserve up to 30% more electricity than that of a 5-star window AC.

In Addition, AC manufacturing companies are now only focusing on split air conditioners because the innovation in window AC is minimal. 

On the other hand, split AC is far more advanced, built for long cooling sessions and futuristic AC design type.

Having said that, split AC costs way more than window AC and also it is not portable as window AC. 

So, if you are low on budget and looking for a portable AC solution, then you can choose window AC.

And, if you are going to use your AC for only 1-2 hours a day, window AC is the right choice.

How inverter AC differs from non-inverter AC?

Inverter AC is always better than a non-inverter AC because it generates cooling faster and consumes less energy, overall. 

The main difference between these 2 types is the compressor.

An inverter AC compressor uses variable speed motor which operates according to the temperature requirement of the room. 

The compressor never stops, and that’s why it doesn’t require additional power to start again and again.

For this reason, inverter AC is also known as variable speed AC.

On the contrary, non-inverter AC uses a fixed speed compressor which starts and stops periodically.

And due to this stoppage, it uses more energy and gives inconsistent cooling experience.

Check the in-depth difference between non inverter and inverter AC.

My room has a small size how much AC tonnage capacity should I need?

As we already said that we should pick AC tonnage capacity according to our room size. 

If you have a smaller or a compact room size like (10 x 10 feet), then a 1-ton AC is an excellent choice to provide enough cooling.

In the case of (12 x 15 feet) medium-sized room, you should look for a 1.5-ton AC size.

In the case of large room size (15 x 20 feet), consider buying 2-ton capacity AC.

What will happen if you choose the wrong tonnage capacity?

There are simple consequences of choosing the wrong type of AC tonnage capacity.

Firstly, let us suppose you select one tonnage AC capacity for a medium-size room then your room will simply lack enough cooling, which is a waste of your money.

Secondly, if you choose two tonnage AC capacity for the same size room, then the large compressor of the AC will burn your electricity.

You will end up paying an extra monthly electricity bill which is again a waste of your money.

So it is always good to select the best capacity of AC for your room.  

What are the factors that can affect my AC’s cooling capacity?

This is an important question, and every AC buyers should know that many factors can decrease AC cooling capacity.

Here is the list of some of the most critical factors.

  1. Room size is larger than the AC tonnage capacity
  2. If there are more than two members (not more than 4), living in the same room
  3. Your room is at the top-most floor of your building
  4. Room’s roof or side-wall comes in direct contact with the sun rays
  5. Extreme humidity and heat in your area
  6. Improper maintenance of your AC unit
  7. Delay in regular service of your AC

If your room comes under 2nd, 3rd or 4th condition (as listed above) then you should buy an additional 0.5 ton AC unit according to your room size.

What is the benefit of buying a 5 star AC?

These 5-star ratings are given by BEE India (Bureau of Energy Efficiency) which represents how good an appliance (Air Conditioner) can use electric power.

In the case of air conditioners, better star rating means the AC unit can generate the same amount of cooling but consuming less power.

So in simple words, 5 star AC means maximum possible power saving by the unit.

Which inverter ac is best in India?

These are different types of inverter AC variants available in the indian market, but Carrier CAI18EK5R39F0Daikin FTKF50TV, and LG KS-Q18YNZA are currently the best inverters ACs as per our list.

We know that the initial cost of an inverter AC is high. But the effective cost becomes less than non-inverter AC after using it for two or more years.

Which ac is the best aluminium or copper condenser?

This is one of the most frequently asked questions, and very easy to answer.

Both aluminium and copper condenser ac is the right choice, but due to the chemical nature, Copper is less active to corrosion, which adds more life to your AC unit.

And, the thermal transfer rate of copper is better than aluminium, which means better cooling capacity.

On the contrary, aluminium isn’t too bad, but we would recommend buying a copper condenser AC unit whenever possible.

Which type of AC is best for your home?

Generally, a Window or Split AC is a prevalent type of unit for home. However, portable ACs are also suitable for home air conditioning.

Which mode is best for an AC?

Your AC remote control comes with several types of predefined modes to set your room temperature. 

And mostly economical mode is always the best mode to keep a balance between cooling and power savings.

Which is the best refrigerant for split AC?

R-32 is currently the best refrigerant and next generation for split AC.

It is a hydro-fluorocarbon refrigerant that is completely ozone layer-friendly, has less impact on Global warming potential (675) and provides better efficiency.

And R-410A is considered as the second-best refrigerant due to good efficiency, no harm to ozone but a little more harm to Global warming potential (2090).

After that, R-22 is slightly outdated refrigerant and has a slightly low economic performance.

Do I need to buy a stabilizer with my AC?

In most of the cases, you do not need to purchase stabilizer with any inverter ACs as they come with built-in stabilizers.

Some AC can also work in extremely low to high voltage fluctuation range between 170V to 270V. 

And, if your AC doesn’t have inverter technology, an auto-cut stabilizer can reduce the risk of the appliance damage and yes it is recommended in this AC.


So, we are sure that after reading this information you can find your best ac in India this year.

AC Buying Guide

Obviously, the main reason to get an air conditioner is to keep your home colder when it is warm outside. But air conditioning is really a complex system of controlling the air temperature, humidity and cleanliness, as well as the movement of air in conditioned spaces. This short guide was created to help you understand the basics of how air conditioners work and to help you choose the right air conditioner for you. We do not sell any air conditioners ourselves, so you can be assured that all of the information in this guide is independent and unbiased.

In this Guide:

1. Background on Air Conditioners

2. Features and functions to look for in Air Conditioners

3. How to find the Best Air Conditioner for you

1. Background on air conditioners

Did you know that in reality, an air conditioner is really making your home ‘less warm’? A simple description of the process is that when air gets cycled through the air conditioner system, heat from the air is absorbed by the air conditioner, and the cooler air is blown back into the room and/or throughout the house. Since this guide is not for engineers, we will skip the technical discussion of how this happens; curious minds can find out easily enough elsewhere.

2. Features and functions to look for in air conditioners

Air conditioners come in many shapes and sizes, but there are really two main types of air conditioners (swamp coolers and other air cooling methods not included). Air conditioners are either self-contained and designed for single or multi-room use, or they are designed to cool the entire house in conjunction with the furnace and ductwork system. The most important feature of any air conditioning unit is measured in cooling capacity.

Cooling capacity is measured in BTUs or British Thermal Units. This figure represents the amount of heat required to lower or raise the temperature of 1 pound of water 1 degree Fahrenheit. The heat that is extracted from your home by an air conditioner is measured in BTUs.

Single or multi-room air conditioners
These air conditioners are designed to work in smaller spaces, such as one room or one level of a home. They can be the perfect solution in a variety of situations: you want to keep the baby’s nursery room cool, one room in the house gets particularly warm, you live in a ranch and only need one level cool, etc., etc. Single or multi-room units are also known as ‘window A/C units’ because they are installed in windows to allow the movement of air from the inside to the outside of the home. These air conditioners come in different capacities, usually somewhere between 5,000 and 30,000 BTUs.

Whole-house air conditioners
These air conditioners are designed to work in conjunction with your home’s furnace/heating system to cool your home. Typically, a unit is placed outside the home and additional equipment is installed in your furnace. This is so the cooler air can be blown throughout the home via the existing ductwork that is directly connected to the furnace. Additionally, the air conditioning system will have to be connected to the thermostat or other control devices to give you some way of controlling the settings on the air conditioner system. Whole-house air conditioning systems typically come in capacities of 18,000 to 60,000 BTUs.

Air conditioners are electric devices, and there are standards in place to determine how efficient the air conditioners use electricity to power their functions. This is known as the SEER (Seasonal Energy Efficiency Ratio), and the higher the number, the more efficient the unit is. The government sets minimum efficiency standards as to the lowest SEER levels allowed.

Where to buy
Most of the whole-house air conditioning systems are sold nationwide through companies and independent dealers and the larger home improvement stores. They will provide installation as well. Many of these dealers have excellent web sites that can give you all the information you need and even schedule appointments for estimates and installation. The single and multi-room air conditioning units can be found at major hardware stores and require minimal installation.

3. How to find the best air conditioner for you

Researching online is the best place to start when shopping for an air conditioner. You may or may not be sure which type of air conditioner would be best for your situation, so doing research on specific models will help you narrow down your choices by price and capacity. Many air conditioners can be financed, either directly with the manufacturer/dealer, or sometimes with large retail chains (usually by opening up a store credit card.)

The most important component to consider when looking for an air conditioner is capacity. Unlike other appliances in the home, it IS possible to get ‘too much power’! A unit that is too large is not only more expensive to purchase and operate, but it also won’t work as well. If an air conditioner has too much capacity for your home, the air will cool quickly, but this could be counter-productive. This is because the moisture is removed as the air is pulled across the cooling coil in the unit. If an oversized unit cools the air too quickly, the unit shuts back down and there isn’t enough time for the moisture to be removed from the air and the inside will remain humid. On the other hand, choosing a unit that is too small is bad because it may not be able to do the job on some of the hottest days. It would be possible to run the unit all day long but never achieve your desired cooling temperature.

Many of the top air conditioning manufacturers recommend that you do not leave the decision of capacity to chance or guesswork. As each home is different in terms of its ductwork, heating patterns, and layout, they recommend that you have an experienced professional determine the proper capacity air conditioner.

best air conditioner

Beyond capacity, you should consider the efficiency of a unit because this can help save you money over the life of the air conditioner unit. Don’t be fooled by marketing terms like ‘high efficiency’, though. The one and only number to compare efficiency is the SEER number, and the higher the better.

Make sure to compare warranties among competing brands carefully. Do they include the same components, or is there a significant difference in coverage. Are any labor costs included in the warranty?

If humidity is a problem in your area, find out what (if any) additional accessories need to be installed to control humidity.

Air conditioners are controlled by thermostats, which simply measure the temperature of the air and either turn on or turn off the air conditioner once the ambient air temperature has reached a certain level. You may have the option of getting a programmable thermostat, which gives you the ability to program various ambient temperatures based on time of day or day of the week. For example, if no one was at your home during the day on weekdays, you could program the temperature to be a little bit higher, then have the air conditioner cool the house back down to your desired temp for when you get home. Some systems even incorporate humidity controls into your system. Programmable thermostats can save you operating costs because the system is on less often.

Air conditioning units that have more than one speed are generally more efficient than single-speed units because they don’t have to use more energy than needed.


Some air conditioners are noisier than others, and if this is a concern for you, make sure to hear the unit in action before settling on one model.

Finding a dealer or model
OK, you’ve done your research, you’ve found what you think is the type of air conditioner that you want, know the features that are important to you, what range of capacity you’ll need and what price range you’re probably in. What next?

To find the specific model or dealer, it might pay to ask your friends and colleagues if they have had any experience with dealers or if they like or dislike their own air conditioning system. Instead of or in conjunction with personal referrals, you can find out if any of the air conditioner manufacturers, dealers or models have earned the endorsement of any legitimate, third-party rating entity. Finally, you may consider the brand name as a criterion. Generally, the best-known and most successful businesses are those that do a good job, earn a good reputation and earn repeat business.
