Buying Guide For AC under 40,000 – Points to Consider
Buying an AC is never easy because you have to consider various points. The factors that determine your choice of the ideal AC for your home range from performance to electricity savings and pricing to the AC’s features.
This buying guide concentrates on ACs available in the Rs 40K pricing range. Hence, we have one of the parameters clearly defined.
Air conditioners in this Rs 40K range are usually the 1.5-ton and 5-star rated appliances.
Before purchasing the AC for your home, you should know what the AC tonnage or capacity signifies and how the star ratings are arrived at.
AC Tonnage – The Concept
In simple terms, tonnage is the rated cooling capacity of an AC and is equal to 12000 BTU/hr. You can also state that AC's tonnage is its capacity to remove a specific quantity of heat from the room in an hour.
Thus, a 1.5-ton AC can remove 18000 BTUs of heat in one hour.
We will not go much into the mathematical or scientific aspects of tonnage as they are not required for deciding on the ideal AC for our homes. We concentrate on other factors that help determine the right AC tonnage for our family.
Room Area and Volume
Indian bedrooms usually have their ceiling at a height of around 10 feet. This table should make it comfortable for you to decide on the right tonnage for your room.
|Room Area in square feet||Room Volume in cubic feet||Ideal recommended tonnage|
|Small rooms up to 80 square feet||800 cubic feet||A 0.75-ton AC should be OK.|
|Bedrooms and conference rooms up to 120 square feet||1200 cubic feet||A 1-ton AC can do the job.|
|Master bedrooms or larger rooms with area up to 190 square feet||1900 cubic feet||You need a 1.5-ton AC.|
|Living rooms or large office spaces up to 300 square feet||3000 cubic feet||The recommended capacity is 2-ton AC|
For academic interest, a 1.5-ton AC consumes around 1500 W/hr of power. It translates to approximately 1.5 to two units in an hour. It is an average figure because the actual consumption depends on various other factors.
The Room Location
Rooms facing the sun or the West direction have greater exposure to the sun. Hence, they tend to heat up quicker than the rooms that do not have direct solar exposure.
Similarly, the rooms on the apartment top floors have their ceilings exposed directly to the sun. Such spaces require you to go for higher tonnage.
The number of windows in the room also plays a critical role. The amount of furniture and electrical appliances in the room are also determining factors. If there are more people cramped inside the room, the heat levels are higher. Hence, you need ACs with higher tonnage.
The Temperature Outside
In places like Delhi, the summer heat can be oppressive. The temperatures outside could touch more than 40 degrees Celsius.
Simultaneously, places like Bangalore do not witness such temperature in summer. Hence, the demands for a home in Delhi will not be the same as for a home in Bangalore.
It suggests that selecting the ideal tonnage is never an easy job. However, the table listed above should give you a fair idea of the AC capacity to have in your room.
Star Ratings – The Concept
Before we discuss the star ratings, here are the factors that affect the AC's efficiency.
Energy Efficiency Ratio (EER) is equal to the amount of heat removed by the AC in one hour divided by the power it consumes during the period. Though EER measures the AC's efficiency, it does not present an accurate picture because it performs differently during the summer than the winter or monsoon seasons.
Factors like the external temperature also play a crucial part in AC's functioning and power consumption. Therefore, you have the concept of SEER or Seasonal Energy Efficiency Ratio. In India, you have the concept of ISEER or Indian Seasonal Energy Efficiency Ratio.
We need not go deep into the calculation methods because the Bureau of Energy Efficiency has stipulated that every AC manufacturer must indicate the ISEER value prominently on the appliance. By looking at the star label, you get the ISEER of your AC.
The Bureau of Energy Efficiency has also proposed a star rating plan for split AC labeling. It is as follows.
|Star Rating||ISEER Band effective from 01.01.2020 to 31.12.2021||ISEER Band effective from 01.01.2022 to 31.12.2024|
|1-Star||3.30 to 3.49||3.50 to 3.99|
|2-Star||3.50 to 3.99||4.00 to 4.49|
|3-Star||4.00 to 4.49||4.50 to 4.99|
|4-Star||4.50 to 4.99||5.00 to 5.49|
|5-Star||Greater than or equal to 5||Greater than or equal to 5.50|
You can check out the ISEER rating and the star rating to decide on the ideal appliance for your home. The higher the rating, the better is the energy efficiency.
We have discussed aspects like tonnage and star ratings to give you an idea about the capacity and energy consumption of your AC. While these aspects are crucial, you should not ignore the available features on your AC because they determine the AC's pricing.
Here are some features to concentrate on when purchasing an AC under 40K
Features to look for in the best AC under 40K
Split AC or Window AC
Nowadays, no one prefers window ACs. However, they deliver excellent performances in keeping the temperatures cool. As people prefer split ACs, we shall concentrate on the features that are exclusive to split ACs.

Compressor – Whether to go for an inverter compressor
Different Operational Modes
ACs function in various modes, depending on your cooling requirements. Different manufactures might give other names, but the processes are similar. However, you should also note that all these features might not be available in all ACs.
Instant Cooling Mode
The primary functionality of your air conditioner is to cool the room as quickly as possible. However, there are occasions when you need immediate cooling as you switch on the AC.
The Instant Cooling Mode, also known as Glacier Mode or Himalaya Cooling Mode in some brands, allows this facility.
In this mode, the AC fans work at a higher speed than the regular mode. Therefore, the airflow is better, and there is quicker cooling
It can be difficult for you to switch off and on your AC during the night as it could disturb your sleep. The Sleep Mode available on almost all ACs in this pricing range works by increasing the temperature by one degree per hour for a couple of hours.
Subsequently, it maintains the temperature at constant levels. Thus, you feel comfortable and have a peaceful sleep.
This mode is not available in all ACs. The Eco Mode is a power-saving mode that adjusts the temperature setting and fan speeds, depending on the cooling requirements. As the compressor runs at varying speeds, it saves power.
The Dry Mode is the ideal one to have in the monsoon season. During the rainy season, the moisture and humidity levels are high. Hence, the interiors can be uncomfortable.
The Dry Mode uses dehumidifiers to eliminate humidity and cool the room. This mode requires the fans to run at slower speeds.
Copper Coils Vs. Aluminum Coils
The debate between copper and aluminum coils will always rage. Both these metals are useful when it comes to efficiency and performance.
Copper coils are better at heat transfer than aluminum, whereas aluminum coils are cheaper. Copper is more robust than aluminum. At the same time, aluminum has better malleability.
On the maintenance front, copper coils are better because they have rust and corrosion-resistant properties.
AC manufacturers use different technologies to protect copper/aluminum tubing. Blue Fin technology and Ocean Black technology involve coating the tubes with a special coating to protect them from corrosion, rust, humidity, moisture, and salt. It gains significance in coastal areas where the salt and humidity levels are higher.
The refrigerant or the coolant is a crucial aspect of an air conditioner. The most common refrigerant is R32, as it has the least Global Warming Potential amongst comparable refrigerants. Besides, it has zero ozone depletion potential. Hence, it is one of the most environmentally-friendly refrigerants in the market.
Besides the primary features discussed above, you should look for other elements in your AC.
We are living in the smartphone age, where you can control electronic appliances using smartphone apps.
The air conditioners available in this budget range come with features like Smart Diagnosis, where you can diagnose various errors if there are any problems with your AC. It makes for easy troubleshooting.
Some of the latest AC models feature self-cleaning features where the appliance keeps functioning for some time after switching it off. It uses the condensed water from the evaporator tube to clean the machine and ensure that it is ready to deliver quality performance when you switch it on again.
Voltage fluctuations are common in India. Such instances can cause damage to the AC's expensive components. Hence, people used external voltage stabilizers in the past. Today, ACs can work in a wide input voltage range from 160 to 290V. It has eliminated the need for a stabilizer.
Air conditioners come equipped with filters to eliminate dust and other allergens from the air you breathe.
Some latest models feature HEPA and PM 2.5 filters to remove the minutest of pollutants. Asthma patients and older adults would love their ACs to have these features.
Power outages are also common in India. When there is a power cut, the AC units stop functioning. Generally, you had to reset the temperature settings after the resumption of power.
Today, ACs come with an auto-restart feature that enables these appliances to resume operations from where they left off at the power cut.
We have discussed every aspect of the air conditioner you should concentrate on when purchasing one for your home. This buying guide has simplified the process, whereby it should not be an issue for you to decide on the ideal AC for your home.
