Best 1.5 Ton Split AC – Buying Guide

Best 1.5 Ton Split AC in India 01

Now that we’re over with the list of the best 1.5 Ton Split AC the Indian market has to offer, let’s move on to other things. Here is a buying guide we’ve compiled with useful tips and relevant information for AC purchases. You can refer to this guide if you want to get the ideal AC for yourself and want to have an accurate estimation of the ACs performance before purchase.


Different Types of AC

Let’s start with the types of ACs you can choose from. While our list consists of Split ACs, there’s also another option you can look into. Based on how they work, ACs fit into three categories. Here are some brief details about them.


1. Window AC

The first widely used model of ACs is the Window Air Conditioner. This type of AC was once prevalent in Indian homes. These ACs can cool a single room. So, if you happen to have a large house, you may need to install them in every room that needs cooling.

Even though these ACs aren’t particularly inexpensive and Split ACs being able to offer much performance at a similar price range, these ACs are still in use. Most of the people using these ACs usually live in apartments and small houses.

These air conditioners have their components collected into one single unit. They contain cooling components like evaporate coils, a compressor, a fan and a refrigerator. The unit can then be mounted onto a window.

Most window ACs come in different sizes, for both small and large rooms. An important thing to remember is that the size of the AC directly affects its cooling capacity.

Benefits of Window AC

  • Ideal for single rooms.
  • Provides large area cooling at a lower price.
  • Easy to set up and uninstall.
  • No need for additional ductwork.

Drawbacks of Window AC

  • Quite noisy compared to their Split counterparts.
  • It’s bulky and noticeable, as it needs to be installed to a window.
  • Installation needs to be next to a suitable electrical outlet.


2. Split AC

Split ACs are the most popular air conditioners in use today. They have two units, an indoor one and an outdoor one. The outdoor unit needs installation to the adjacent exterior wall. This unit consists of the compressor, the condenser coil and the capillary tubing or expansion oil.

Meanwhile, the indoor unit has a cooling coil, air filter and long blower. In between the outdoor and indoor units lie conduits that connect them carrying refrigerant lines and drainage tubes.

Benefits of Split AC

  • The compressor and the fan which cools down the compressor are in the outdoor unit. So, Split AC can operate quietly.
  • Split ACs don’t need large wall holes or expensive ducts for installation. Unlike Window ACs, these can be installed anywhere.
  • You can install the outdoor compressor unit reasonably far from the main unit.
  • These ACs are easier to clean and maintain.
  • Easy to install.


3. Portable AC

You can use a portable air conditioner for a fair amount of cooling. The good thing about these is that they are easy to move around and use less energy. If you want portability, you can also try going for air coolers.

Benefits of Portable AC

  • Portable and uses up less space.
  • No need to set up, just plug the AC into a standard outlet.
  • Has some of the comfort functions of a regular AC including dehumidification, fans and air purification.

Drawbacks of Window AC

  • Cooling prowess is far less than full ACs.
  • Not ideal for large area cooling.
  • Doesn’t last long compared to other types.


Window AC Vs. Split AC – Which one should you buy?

In the end, it boils down to personal preferences. Each one offers you a different set of advantages. Both types are common in Indian households, so to help you pick the right one, here is a brief table summing up the distinctions.

Window ACSplit AC
Needs a large opening in the wall for installation.More size efficient, takes less space.
Is less energy efficient.Provides more cooling per watt than Window ACs do.
As all components are in one place; noise production is high.Operates with the barest sounds since noisemaking components are outside the room.
Uses older technology, less flexible to use. Split ACs are newer, and so they offer more control over the cooling.
Innovation on Window ACs is stale.Split ACs come with advanced technology that delivers more power.

If you’re willing to go save some cash, you’ll be alright with Window ACs. However, if you live in a hotter area, then you could still save some money if you go for the best 1.5 Ton Split ACs.

Non-Inverter AC Vs. Inverter AC – Which one is better?

In terms of pricing, non-inverter ACs do give a small edge. However, that doesn’t really work out since you’d have to pay more during installation. Inverter ACs provide the best overall quality and make up for their expensive costs by taking out repair costs, making them good options in the long run. So, as you can see, non-inverter ACs are fairly limited.


1. Non-Inverter AC

A non-inverter AC unit comes with a motor compressor that has a fixed speed. They don’t operate continuously, but rather keep turning on and off to maintain a set temperature. The compressor switches off whenever that temperature is reached. Due to these frequent on and off cycles, the compressor produces quite a lot of noise. More importantly, these cycles end up making these ACs use a lot more energy than their inverter counterparts.


2. Inverter AC

Inverter AC units come with a variable speed compressor, which adjusts the refrigerant flow inside the unit to maintain the set temperature. Quite a bit of the power consumption of an inverter unit comes from the compressor motor’s speed. Through the use of a variable-frequency sensor, the AC controls the motor speed to regulate the refrigerant flow in the unit.

This mechanism allows the AC to provide the right amount of cooling and heating, eliminating the need for frequent start-stop cycles. As a result, you get more energy savings in the long run.

Here’s a chart that shows off the differences between both.

Inverter ACNon-Inverter AC
Inverter ACs have a motor with adjustable speed. The compressor always stays on, moving the temperature up and down to stay on the set temperature.Non-inverter ACs have a fixed compressor, along with a fixed speed. The compressor turns on and off.
Inverter ACs can adjust the compressor speed to adjust the refrigerant flow. The non-inverter AC delivers a fixed amount of power, based on the room temperature.
Inverter ACs cool and heat continuously.Non-inverter ACs, on the other hand, turn on and off to keep the temperature to a set degree. The process of going on and off can increase power consumption.
Inverter ACs are more costly than their non-inverter counterparts.Non-inverter ACs cost less than Inverter ones. However, the maintenance costs are high, so you don't save that much money.

Things to Consider While Purchasing the Best Split AC

Now, let’s take a look at the technical aspects which you need to consider before buying the best 1.5 Ton Split AC.


1. Capacity

The first thing you should be considering when buying an AC is its cooling capacity. The “Ton” part denotes the amount of heat removed by the AC per hour.

What you need to keep in mind when checking the cooling capacity is that the higher the ton is, the more cooling capacity you’ll get. In other words, an AC with more tonnage can cool a large space quickly.

You have to measure the room in which you’ll be installing the AC first, to get the ideal capacity. Based on the measurements, you can choose just the right AC for the room. You’ll find the capacity of the air conditioner in the product specifications or instruction manual.

Here’s a table you can refer to:

Room Size (In Square Feet)AC Capacity (In Tons)
90-150 1
200-300 2


2. Compressor

The compressor is the heart of the AC’s cooling system. The entire performance of your AC will depend on this component. So, you must pay attention to what kind of compressor you’re getting if you want something that meets your needs.

The compressor enables cooling by compressing the refrigerant gas to high pressure. This converts the gas to a high-pressure liquid at a high temperature. Once the liquid goes through the condenser coils, they take away the heat from the liquid and release it into the surroundings.

However, the pressure remains high. The expansion valve lowers the pressure and converts the liquid to gas. Afterwards, the gas then goes through the evaporator coils. They absorb the heat from the gas and cool the room down.

Most air conditioners use two kinds of compressors. Here’s a brief explanation of how they work.

Reciprocating Compressor

This compressor uses a mechanism similar to the one in a car engine. As in, it works on the concept of pistons and cylinders. The pistons move back and forth, compressing and releasing the gas.

Rotary Compressor

Rotary compressors use two rotors turning in opposite directions. Because of that movement, air gets trapped in-between, and compression occurs.


3. Coil

The AC relies on three main processes to work. These are Compression, Condensation and Evaporation. Looking deeper, these three processes work on a single crucial element. That’s the refrigerant. It’s a chemical that can be continuously converted back and forth between liquid and gas. By changing state, the refrigerant absorbs the heat in a room before releasing it outside, thereby cooling the air inside the room. This kind of heat transfer occurs inside the coil. So, the coil can also play a significant role in the functioning of an AC unit.

There are two types of coils in an AC. They are the evaporator coil and the condenser coil. As you can surmise from above, the quality of the coils can affect the performance of your AC. Coils are generally made from two materials, either copper or aluminium.

Copper Coil

Copper coils need little maintenance and have high durability when compared to others. They’re the best choice, as they have better heat transfer properties, making them perfect for fast cooling. The only downside is that they’re more expensive than other types. As they come with anti-corrosive properties, they’re best suited to high humidity or coastal areas. The best 1.5 Ton Split ACs usually come equipped with these.

Aluminum Coil

Aluminium coils are less expensive than their copper counterparts. However, they also need more maintenance. Besides, they provide slower cooling as well. Another thing is that unlike copper, which you can repair and reuse in cases of damage, you can’t do the same with an aluminium coil. You’ll have to get a replacement for the latter.


4. Star Ratings

The Star Ratings work with the EER. EER (Energy Efficiency Ratio) is the amount of heat removed per watt. Increased EER means better performance and power savings. Each Star Rating, starting from 1 Star to 5 Star denotes a specific range of EER, starting from low. The higher the Star Rating is, the more EER you’ll get. Hence, you’ll have more energy savings and performance with a higher Star Rating.

Every manufacturer provides the information for EER and Star Rating on the same level. Do note, though, that the price may rise the higher the Star Ratings get. But you’ll be saving a lot of money in the long run.


5. Cooling Speed

Always be sure to get an air conditioner that has multiple cooling speeds. Don’t opt for one that comes with a single cooling speed. If you do one of these, then you won’t be able to adjust the temperature according to the outside temperature. Not only that, but you’ll also be unable to save up some electricity bills by reducing the speed when it’s not needed.


6. Air filter

If you’re going to buy an air conditioner, you have to take note of the indoor air quality. Be sure that you purchase an AC with a good filter if you want to relax and breathe in some fresh air. If the AC has a good filter, then you get clean air, and you also get improved cooling and energy efficiency. That is because bad filters can cause dust to gather in the evaporator coil, hampering the AC’s smooth operation.

Most of the best 1.5 Ton Split ACs also come with a basic filter system that keeps the air clean. To get the best air quality, make sure your AC has a multi-stage filtration system and a PM 2.5 filter.


7. Noise

Split ACs can work near noiselessly, unlike their Window counterparts. As their most active parts are outside on the other side of the room, you’ll barely hear any noise. Just make sure you check the noise level of the product and make sure it’s bearable. Otherwise, the AC might interrupt your sleep or other activities that need focus.


8. Modern features

The newest split air conditioners come with features that make your life much more comfortable. You won’t find any of these features in the older models. Of course, they have basic features like temperature control and auto mode. However, they also come with additional innovative features.

Some of these features include the following:

  • Turbo Mode: Cools the room instantly.
  • Sleep Mode: Maintains a comfortable temperature optimised to offer better sleep, using sensor data.
  • Dehumidifier: Maintains the humidity level of the air and keeps it healthy.
  • Filters: These remove dust along with other pollutants in the air.

Some modern split ACs also come with intelligent features like Bluetooth accessibility, wifi compatibility, automatic sensors and others. Having these feature allows you to tailor the performance of the AC to the best of your comfort.

However, do remember that you’re going to have to pay a higher price, the longer the list of advanced features gets.


9. Brand

As always, consider the brand’s reputation among the populace before you get your AC. The build quality, along with warranty and after-sales service depends on the brand. The ACs we’ve listed are from some of the best air conditioner brands in India. However, you can also take a look at Whirlpool, Lloyd, Panasonic, Blue Star and Philips air conditioners.


10. Price

The things that go into determining the price of a split air conditioner are the lifespan, performance, and feature list. To get at least 10 years of smooth use from an air conditioner, you need to get a pricier air conditioner. The best split air conditioners cost from Rs 30000 to Rs 50000, approximately. If you’re on a budget, then it’s best to go for a basic model. However, if the price isn’t your deciding factor, then we suggest you go for the model with maximum features.


11. Warranty

ACs need a lot of money for maintenance. As they use sophisticated mechanisms, repairs or component replacements can often be expensive. Hence, you should get a product that comes with a long period of warranty. Then, you can have the AC fixed with no extra costs during the years of warranty.


12. After-Sales Service

Some brands don’t have particularly good after-sales service. If you want a smooth installation and high-quality customer service, then be sure to go for the most reputed brands and also read the reviews of the users who have already bought the product.


Best 1.5 Ton Split AC – Frequently Asked Questions

1. What kind of AC is better for long time use?

Both Window ACs and Split ACs are very durable and can last a long time. However, split air conditioners have some extra edge over the window ones.

For a start, as the split ACs are newer, they come with more advanced technology, including better protection against certain hazards. Another thing is that the number of split ACs in the Indian market is increasing every day. This means that if you get a split AC, you have a better chance of finding component replacements than you will have with a window AC.


2. Do Window ACs come with Inverter Technology?

Inverter technology is mostly present in Split ACs. Though, brands like LG and Voltas are now producing some Window ACs that have compressors running with inverter technology.


3. What is wrong with getting a non-inverter AC?

Three things. Firstly is the amount of money you spend on it. Though you may buy a non-inverter AC to save some money because of the lower price, you might end up spending that saved money later on. That’s because non-inverter ACs have a fixed speed compressor and aren’t particularly energy-efficient. So, as the power bill will be much more in comparison to inverter ACs. That’s how you’ll end up paying thousands more because of using a non-inverter AC, despite the low initial cost.

Secondly, non-inverter ACs come with a fixed compressor, which may result in the room getting overcooled. To clarify, even if you set the temperature to 25°C, the resulting output would go as low as 22°C to 23°C. As a result, many might feel uncomfortable being in the room. This overcooling happens because the fixed compressor is designed for peak heat load. So, despite the thermostat switching the compressor off at 25°C, the refrigerant still ends up absorbing the heat from the rooms air and converting it into gas.

The last thing is something we’ve already talked about in the earlier question. Inverter ACs are starting to appear more in the Indian market while the non-inverter ones are becoming more obsolete. You’ll have to buy them at your own risk, as the spare parts might become hard to find in the future. Also, these ACs need more maintenance, and certain parts need full replacements if they get damaged.

You won’t want to buy a new AC if you don’t find the spare parts necessary for the replacement. Hence, always go for the newest models, which come with inverter technology.


3. Do Split ACs need a voltage stabiliser?

For the most part, they do. If you don’t want your AC to get permanent damage, it’d be best to connect the AC to a voltage stabiliser.

However, some of the best split ACs do come with integrated voltage stabilisers for a specific range of voltage fluctuation. If you have fluctuations within the supported range, you don’t need to get a stabiliser.


4. What are the common modes in a split AC?

Most of ACs come with four main modes. To be specific, these modes are auto, cool, dry and fan.

Auto Mode allows the AC to operate on its own, changing settings as needed according to sensor data about the ambient temperature.

Cool Mode allows you to set a specific temperature in the room, which the split AC maintains using varied cooling speeds. The temperature’s never going to dip below the set level. The Cool Mode for these ACs are going to be more energy-efficient than that of window ones, as the split AC doesn’t spend additional power turning the compressor on and off.

Dry Mode is perfect for the rainy season or any other weather condition that makes your room unbearably humid. The AC works as a dehumidifier, allowing you to breathe better and also keeping you healthier by reducing the bacteria in the air. Besides, this can also prevent moisture from damaging your wooden furniture.

Fan Mode allows you to make the AC focus more on air circulation, in case there’s so little of it that you start feeling suffocated.


5. What can I do to keep up the performance of my Split AC?

One of the things you can do is keep the air filter clean. The filter gathers up dust and other airborne particles before the cold air goes into the room. A lot of these particles being on the filter means you’ll have worse air quality.

So, always be sure to clean the air filters every once in a while. If you use the AC regularly, make sure to do it once or twice a month at least. You can opt for the annual maintenance service to let the technicians clean the filter thoroughly along with other parts. Though, you can also ask the service provider’s installation team for instructions on how to clean the filters yourself.

There are also other things which you can do. Ensure the outdoor unit is facing an open area with no blockage. Keep the drainpipe clean and unblocked as well. Don’t place the indoor unit on a portion of the wall where direct sunlight can reach, as that can heat up the AC.

Another small thing that helps is letting the hot air flow out of the room, by using a fan or the ACs fan mode before you close your windows and run the AC on Cool or Auto Mode.
