Stuck between Daikin and Hitachi for your next AC? It’s a tough call. But does brand reputation always mean better performance?

This guide breaks down the cool facts in cooling efficiency, features, durability and value to help you make the best decision.

Let’s get to it!

Daikin vs. Hitachi – Which Is the Better Air Conditioner?

Both the Daikin and the Hitachi are premium inverter split air conditioners that can cool up medium and big sized rooms with high energy efficiency. Both were very good, feature rich and made using quality materials such as 100% copper condenser coils. But in case we had to choose a winner it would be Daikin MTKM50XV16. Although the Hitachi does have such impressive cooling capabilities as iceClean and Xpandable+ technology, the Daikin beats it in a slightly higher ISEER rating (5.7 vs. 5.6), much lower noise (31 dB vs. 37 dB), and a lower price by approximately 1,500. Most importantly, Daikin also has a broader high-ambient operation range of up to 55 °C than Hitachi 54 °C.

These two air conditioners have the best features as well as high cooling capability that suits the hot summer of India.

We will be comparing every detail of each of these ACs to determine the actual comparison. We have a long way to go and we should begin.

Daikin vs. Hitachi AC – 1.5 Ton 5 Star

Indian summers favour split ACs because with the rise in temperature and the duration of heat waves, the demand on effective and dependable cooling is high. Daikin and Hitachi are both selling 1.5 Ton 5 star inverter split ACs, but both brands come with a different philosophy.

The 1.5 Ton 5 star series of Daikin pays much attention to air purification, self-cleaning, and energy efficiency. Such models as the MTKM50XV16 and the ATKM50UV16VA are also fitted with patented swing compressors, Dew Clean Technology, and PM2.5 or PM1.0 filtration to guarantee clean and healthy air.

We have on the other side of the table the 1.5 Ton 5 star range by Hitachi which focuses on raw cooling muscle and smart features. The RAS.V518PCDIBT and the RAS.Y518PCAISL2 (5700XXL) introduce the Xpandable+ Technology, FrostWash-powered ice Clean, and Wi-Fi connectivity to provide powerful and customisable cooling.

In the table below, you’ll find a breakdown of the major similarities and differences between Daikin and Hitachi air conditioners.

Comparison Table

Daikin 1.5 Ton 5 Star MTKM50XV16

Daikin is the energy efficiency leader, Hitachi is energy efficiency competitive.

Check Price

The most important aspect of energy efficiency is when an AC is used 8-10 hours per day during an Indian summer. The MTKM50XV16 by Daikin is the most economical with an ISEER of 5.7 and annual energy consumption of only 678.92 kWh, which is the most cost-effective to operate in a full cooling season.
The RAS.V518PCDIBT of Hitachi is not a snail either with an ISEER of 5.6 and a yearly consumption of 690.72 kWh. It is a small difference in your actual electricity bills, about 100200 a year, depending on your tariff.
Where the things part a little further is in the secondary models. Daikin ATKM50UV16VA has an ISEER of 5.2 (785.99 kWh) and the Hitachi 5700XXL has 5.1 (823.18 kWh). They both remain 5 star rated, although the difference in annual consumption increases to more than 35 kWh.

Hitachi 1.5 Ton 5 Star RAS.V518PCDIBT

Hitachi Xpandable+ provides it with the advantage of raw cooling power.

Check Price

The base models of both brands have a rated cooling capacity of 5,000 W at 100 percent load, which is the standard of a 1.5 Ton unit. But the Xpandable+ Technology of Hitachi enables its compressor to run at an RPM higher than the standard level providing up to 110 percent cooling capacity, 35 percent greater humidity removal, and 30 percent shorter cool-down time when required by conditions.
Daikin responds with its Power Chill Operation that provides 20 percent faster cooling than the normal mode. It works, but it does not increase the cooling capacity as much as the system of Hitachi does.
Daikin leads in the case of high ambient operation. The ATKM50UV16VA can work at a comfortable temperature of up to 56 °C, and the MTKM50XV16 can work at 55 °C. The highest temperature of the models of Hitachi is 54 °C and 52 °C respectively. This difference can count in very hot areas such as Rajasthan or Vidarbha.

Daikin 1.5 Ton 5 Star ATKM50UV16VA

The filtration technology of Daikin is a different category.

Check Price

Daikin is obviously ahead in case the quality of air is a priority. The MTKM50XV16 is fitted with PM2.5 Filter, and the ATKM50UV16VA is fitted with PM1.0 Apatite Filter that has the ability to trap smaller particulate matter. To make it even worse, the Patented Streamer Discharge technology by Daikin degrades viruses, bacteria and harmful gases within the environment through plasma discharge.
The method of air quality at Hitachi is less complex. Both of them operate on an anti-bacterial mesh Filter or dust Filter that does simple air cleaning but does not compete with the fine-particle filtration that Daikin provides. Daikin filtration suite is more robust in homes with high-pollution or households with members who are prone to allergies.

Daikin vs. Hitachi 1.5 Ton 3 stars split AC Comparisons.

How Daikin and Hitachi AC’s Cools The Air

Daikin and Hitachi also differ in terms of the way they cool and condition air.

At the most fundamental level, the strategy is the same… they both rely on inverter-driven compressors to force the refrigerant through copper coils of the condenser, drawing warm air out of the room, cooling it in the heat exchanger, and forcing chilled air back into the room.

And that is as far as the similarities go.

The greatest variation in the functionality of these air conditioners is the kind of compressor technology, airflow mechanisms, and self-cleaning functions they apply. Daikin depends on Swing Inverter Compressor with Coanda Airflow that is patented, whereas Hitachi depends on Xpandable+ Inverter Compressor with 4 Way Swing and FrostWash technology.

Daikin: Coanda Airflow Swing Inverter Compressor.

In the Daikin, the Swing Inverter Compressor is the major engine that promotes efficient cooling, which is patented.

Swing Compressor design minimises friction and vibration as opposed to the conventional rotary compressors. This assists in a smooth rotation cycle that offers a quieter and more energy efficient operation in long periods.

How does it work?

The compressor also varies its speed in accordance with the cooling needs of the room. Instead of turning on and off like a non-inverter unit, the Swing Inverter increases or decreases power as required to maintain a steady temperature with the lowest amount of wasted energy.

Daikin combines this with Coanda Airflow technology which optimises the flap position of the indoor unit to direct cool air up the ceiling. This enables the air to move more and cover all corners of the room without any furniture or obstructions and gives the room radiant and even cooling.

Daikin has also incorporated Power-Airflow Dual Flaps on the 5 Star models which operate with the Crossflow Evaporator Dual Flaps to provide better distribution of air in the small and large spaces.

Hitachi: Xpandable+ Technology & iceClean.

At the other extreme, we have the Hitachi which uses Xpandable+ Inverter Technology as its principle cooling system.

Xpandable+ is used to denote the capability of the AC to increase its cooling capacity to a level above the standard when the conditions require it. The 5 Star 1.5 Ton model is capable of providing up to 110 percent cooling capacity, 35 percent greater humidity dehumidification and 30 percent reduced cool down time than operating in a standard mode.

How does it work?

The Xpandable inverter will boost its RPM above normal when and where necessary, and automatically adjust to actual ambient conditions outside and inside the room. This is so that during hot summer months, the AC will work extra hard to keep you comfortable without you needing to adjust any settings.

Hitachi is also equipped with iceClean technology which is powered by FrostWash. This cleaning system is self-cleaning and operates in three phases, which are Freeze, Melt, and Dry. The moisture is first condensed and dust trapped on the frost of the coil by FrostWash. The frost then melts and empties the trapped dust in the indoor unit coil. Lastly, the coil is dried by a blower and is clean and thus prepared to operate effectively.

What is the superior cooling technology?

Although it is hard to say that one technology is certainly superior to another, they have their arguments.

Pros

• Daikin Swing Inverter Compressor: The compressor has less friction and vibration, resulting in less noise (as low as 27 dB on the 1.0 Ton 3 Star model) and energy savings that are consistent over time.
• Xpandable+ technology available in Hitachi can extend the cooling capacity (up to 110112 percent) which is especially handy in times of extreme heat waves when you need all the cooling power you can get.

Cons

• Daikin Coanda Airflow is also effective in uniform distribution but it only directs the air upwards along the ceiling. This might not be as cool at first glance as direct airflow in some room designs.
• The Xpandable+ mode of the Hitachi is powerful but it might use more energy at the increased capacity which could affect the electricity bills in the long term.

Daikin vs. Hitachi Size

Regarding size, the Daikin and the Hitachi have some variation in the size depending on the models.

Daikin Indoor Unit Sizes

1.5 Ton 5 Star (MTKM50XV16)

• 32.5H x 106W x 28.4D cm
• IDU Weight: 15.5 kg | ODU Weight: 30.5 kg

1.5 Ton 3 Star (MTKL50XV16)

• 29.8H x 88.5W x 22.9D cm
• IDU Weight: 10.5 kg | ODU Weight: 27 kg

1.0 Ton 5 Star (MTKM35XV16)

• 29.8H x 80W x 22.9D cm
• IDU Weight: 9.5 kg | ODU Weight: 21.5 kg

Hitachi Indoor Unit Sizes

1.5 Ton 5 Star (RAS.V518PCDIBT)

• 29.4H x 105W x 25D cm
• IDU Weight: 11.4 kg | ODU Weight: 31.5 kg

1.5 Ton 3 Star (RAS.D318PCD2BS1)

• 29.4H x 95W x 23D cm
• IDU Weight: 10 kg | ODU Weight: 24 kg

1.0 Ton 5 Star (RAS.V512PCDIBT)

• 28H x 78W x 22.2D cm
• IDU Weight: 8.7 kg | ODU Weight: 26.5 kg

1.0 Ton 3 Star (RAS.G312PCDIBS)

• 28H x 78W x 22.2D cm
• IDU Weight: — | ODU Weight: —

Any of the above models would suit the bill, depending on the size of the room and the amount of space you have on the wall.

In a strict comparison between the 1.5 Ton 5 Star models of Daikin and Hitachi, the latter is a little smaller. It is thinner in depth (25 cm compared to 28.4 cm) and shorter in height (29.4 cm compared to 32.5 cm), and the width is almost the same (105 cm compared to 106 cm). Nevertheless, the Daikin indoor unit is heavier than the Hitachi at 15.5 kg and 11.4 kg respectively, and this is mainly because of the extra parts of Coanda Airflow and Dew Clean Technology.

Daikin vs. Hitachi Accessories.

Daikin and Hitachi both have relatively standard parts and few accessories. They concentrate on a high performing air conditioner and forget the rest. A short list of these parts and accessories supplied by each of these brands is given below:

Daikin: What’s in the Box?

• 1 Indoor Unit
• 1 Outdoor Unit
• 1 Remote Controller
• 3 Mtr. Length Inter Connecting Copper Coil Pipe
• 1 Mounting Plate
• 2.95 Mtr. Insulation Pipe
• 3.7 Mtr. Connecting Cable (Wire)
• 2 Tie Wraps & 9 Fixing Screws

Hitachi: What’s in the Box?

• 1 Indoor Unit
• 1 Outdoor Unit
• Inter Connecting Copper Pipe of 3m Length
• 1 Remote Controller

The two installation kits contain the necessary requirements of a typical installation. Daikin however offers a more complete kit out of the box, with insulation piping, connecting cable, mounting plate and hardware.

• In the case of the Daikin, the installation kit will consist of 2x stronger XLPE insulation with a higher heat withstanding capacity of up to 120°C.
• On the Hitachi, other accessories of the installation such as insulation and connecting cables might be required to be obtained individually or by the installer, depending on the retailer.

The two brands also suggest professional installation and provide post sale service on installation and commissioning.

Daikin vs. Hitachi Features

Ok, so that we have discussed the majority of the basic specs, now on to the good stuff, the cool features. Let’s dive in.

Energy Saving & Star Rating.

Daikin and Hitachi both have models in 3 Star and 5 Star, but the numbers of energy efficiency are slightly different.

In all the board, Daikin ISEER values are slightly higher than that of the Hitachi in 5 Star (5.7 vs. 5.6) and 3 Star (4.4 vs. 4.3). This would translate to a small reduction in the amount of energy used per year on the Daikin models which would accumulate to significant savings over the life of the unit.

It is however worth mentioning that the 3 Star 1.5 Ton model of Hitachi has a slightly lower annual energy consumption of 864.39 kWh as compared to 880.1 kWh of Daikin 3 Star 1.5 Ton model, which has a lower ISEER. This may be explained by the variation in cooling capacity rating (4800W on the Hitachi vs. 5000W on the Daikin).

Self-Cleaning Technology

Daikin and Hitachi both have an inbuilt self-cleaning system but they do it in a different manner.

Dew Clean Technology (on 5 Star models) is an automatic cleaning of the heat exchanger in Daikin, which is done with condensed moisture to wash away dust and debris. This makes sure that it is hygienic and that the heat exchanger is not clogged as time goes by.

The iceClean Technology (frostwash-powered) of Hitachi follows a three-step process, Freeze, Melt, and Dry. The moisture is condensed and then the frost is formed on the coil that traps dust particles. The frost then melts and the dust trapped is removed through the drain. Lastly, the coil is dried by the blower to avoid any growth of microbes.

Both systems are efficient in ensuring the hygiene of the indoor units, with iceClean operated manually by a special button on the remote by Hitachi and Dew Clean operating automatically when Daikin is in operation.

Airflow Modes

The Daikin and the Hitachi have a range of airflow options to provide maximum cooling depending on your room layout.

Daikin air conditioner has the following airflow features:

• Coanda Airflow: Optimises the position of the flaps so that the cool air flows upwards along the ceiling without any furniture or obstructions. This will guarantee cooling in the corners of the room as the air will take longer time to reach the ground. Available on 5 Star models.
• 3D Airflow: Provides consistent air flow and equal cooling of all angles in the room. This feature is applicable in both 5 Star and 3 Star models.
• Power-Airflow Dual Flaps: This is used in conjunction with the Crossflow Evaporator fan to guarantee the even distribution of cool air in small and large areas. On certain 5 Star models.

The airflow characteristics of the Hitachi air conditioner are:

• 4 Way Swing: circulates air horizontally and vertically, making sure that all corners of the room are covered with cool air. This is a common characteristic of all the models of Hitachi in this comparison.
• 24m Long Air Throw: This is designed to cool bigger areas by throwing the cool air as far as 24 metres, and it reaches all corners equally. This comes in handy especially in open plan rooms or bigger rooms.
• Wave Blade Design: Minimises the air cutting noise to operate silently, so that you have a strong airflow without the irritation of a noisy unit.

Operating Modes

The two brands have a range of modes that are used in various situations.

The Daikin air conditioner has modes including:

• Power Chill Operation: 20 percent faster cooling compared to normal mode. This works wonders when one needs a quick drop in temperature in the room and wants to get rid of hot weather.
• Econo Mode: Uses less energy and you can set the maximum limit of consumption. This maximises cooling and ensures the electricity bills are controlled.
• Good Sleep Off Timer: The temperature is raised by 0.5 °C after every 30 minutes, which makes the room temperature more comfortable to sleep in. This eliminates excessive cooling at night.
• Dry Function: It has automatic dehumidification, which is ideal in hot and humid environments. It makes it more comfortable, as it does not decrease the temperature considerably, only excess humidity.
• Auto Mode: The AC senses the current conditions and automatically regulates the fan speed and the cooling output to achieve the best results.

The modes on the Hitachi air conditioner are:

• My Mode: Gives you the ability to store 3 customised presets with custom temperature, fan speed, timer and silent option settings. This allows you to easily alternate between your favourite settings without having to manually change each setting.
• Auto Convertible / Hybrid Convertible: This feature is available depending on the model, where the AC can vary its tonnage capacity depending on the heat load in the room, operating at a smaller capacity when the room is already cool and increasing when necessary.
• Silent Mode: Makes the device less noisy, which is a better fit in bedrooms and when one is sleeping.
• 5 Fan Speeds: Unlike the standard fan speed choices offered by Daikin, Hitachi provides 5 different fan speed choices to allow a more finer control over the intensity of airflow.

Smart Display & Monitoring

The two brands also have display features on the indoor unit, though they vary in functionality.

The Triple Display of Daikin displays three important pieces of information, which are power consumption percentage, set/room temperature, and auto error code. This provides you with total monitoring capability without the remote or an app directly out of the indoor unit.

The 3-in-1 Smart View Display by Hitachi has a temperature accuracy of 0.5 °C, intelligent first-time-right service alerts, and a brightness control with Bright, Dim, and Off options. The dimmable brightness is a pleasant addition to bedrooms where a bright screen could be annoying at night.

Sensor Technology

Daikin and Hitachi both have sensor arrays, but Hitachi goes a step further.

The Hepta Sense by Daikin has 7 sensors on the outside and inside units. All the sensors contribute to the overall functionality of the air conditioner, enhancing the performance of the AC, comforting the users, and contributing to the longevity and life of the AC.

The Intelligent Eye by Daikin regulates the cooling power depending on the presence and movement of people in the room, which consequently turns down the energy use when the room is not occupied.

The Octa Sensor by Hitachi has 8 sensors in the indoor and outdoor units to monitor and control performance. Although Hitachi does not actively sell a motion-sensing capability similar to Daikin Intelligent Eye, the Octa Sensor array helps in enhanced environmental sensing and automatic control.

Stabiliser and Voltage Protection.

Both brands come with inbuilt voltage protection, which is a significant factor to Indian households.

The Stabiliser Inside technology of Daikin manages the voltage over a large spectrum of variation (130 V -285 V) and assists in maintaining smooth operations in case of voltage unpredictability. In most cases, this does away with an external stabiliser.

The SafeGuard System by Hitachi is an electrical and mechanical system that ensures that the outdoor unit is safe against the extreme weather conditions, changes in voltage, and pests. It also has overload safety protection, compressor control and fire prevention.

Anti-Corrosion & Durability

The two brands are highly invested in corrosion protection which is very important in the lifespan of the outdoor unit.

Daikin applies a patented DNNS (Di-Nonyl Naphthalene Sulfonic Acid) anti-corrosive coating on the U-bend side of the indoor unit. This coating is self-healing and it becomes active when chipped or scratched by environmental or chemical pollution. Daikin also has a progressive anti-corrosion treatment in all components of the system and High Impact Polystyrene (HIPS) in the casing of the indoor unit, which also guarantees a fresh and new appearance every year.

Hitachi applies Nano Tech Ultra coating to the interior unit and this prevents rust and corrosion. The outdoor unit is also designed with an anti-corrosive coating to prevent the adverse weather. Also, UV Protection Coating offered by Hitachi assists in safeguarding elements against sun damage with time.

Both brands also incorporate inner grooved copper tubes that are 100 percent in order to increase the heat transfer and quick cooling.

Daikin vs. Hitachi Performance.

In order to effectively evaluate the quality of the performance of the Daikin and the Hitachi air conditioners, we must examine the most important performance indicators among the models.

Comparison of Cooling Capacity.

High Ambient Performance

The ability of the AC to work in extreme heat is one of the most significant performance indicators in the Indian market. The comparison of the brands is as follows:

1. Daikin 5 Star models: 100% cooling capacity at 46 °C with ambient temperature to 55 °C.
2. Daikin 3 Star models: 100 percent cooling capacity at 43 °C, and working ambient temperature of 52 °C.
3. Hitachi 5 Star models: 100 percent cooling capacity at 43 °C with tropical design to operate at 54 °C.
4. Hitachi 3 Star models: 100% cooling capacity at 43°C, tropical design, can be operated up to 52-54 °C.

The 5 Star models of Daikin have a significant advantage in this regard, as they can continue to operate at full capacity at 46 °C, whereas Hitachi can only do 43 °C. This 3 degree difference may matter in areas that have extreme summer temperatures of over 43 °C where the Hitachi may start throttling as the Daikon remains at full-rated cooling.

Both brands are, however, intended to be used in tropical environment and can be used at temperatures much higher than 50 °C.

How Loud Is Each Model?

The above dB levels are on manufacturer-specified levels under normal testing conditions. These figures indicate the noise in the indoor unit when operating under normal conditions.

Daikin air conditioners are quieter than those of Hitachi across the board. The largest difference is in the 1.5 Ton 5 Star category where the Daikin has a 31 dB(A) operation as compared to the 37 dB(A) operation of the Hitachi- a 6 dB difference that is quite noticeable to the human ear.

The ability of Daikin to operate quietly is greatly attributed to its Swing Compressor design which minimises friction and vibration to allow a smoother and quieter running. Hitachi responds to this by the Wave Blade Design technology of the blower, which minimises air cutting noise, but the total noise output remains greater than that of Daikin.

What about ambient noise?

Ambient noise is one of the things to consider when considering noise output. That is the gentle noise that takes place in the majority of the homes. Ambient noise in a typical bedroom at night is approximately 25 to 30 dB. A unit with 27 dB(A) such as the Daikin 1.0 Ton 3 Star would be practically silent, and a unit with 37 dB(A) such as the Hitachi 1.5 Ton 5 Star would be noticeable but not disturbing.

Curiosity about how these results relate to some of the other popular air conditioners in the market? The following are some of the noise levels of similar sized models:

LG 1.5 Ton 5 Star AI Dual Inverter Split AC has a noise of approximately 32 dB(A).

Samsung 1.5 Ton 5 star WindFree AC has an approximate of 21 dB(A) in WindFree mode.

Voltas 1.5 Ton 3 star inverter split AC has a noise level of approximately 36 dB(A).

Daikin vs. Hitachi Warranty and After Sales.

Daikin and Hitachi have strong warranty packages, but it is possible to point out some differences.

Daikin Warranty

• 1 Year on product
• 5 Years on PCB
• 10 Years on compressor

Another strong point of Daikin is its 5-year warranty on the PCB (Printed Circuit Board). The PCB is a rather costly part to change in a contemporary inverter AC and the extended coverage offers added confidence as well as guarantees on the maintenance expenses.

Hitachi Warranty

• 1 Year standard warranty
• 5 Years on controller
• 10 Years on compressor

Optional: 5 Year Comprehensive Warranty at 299+GST (gas charging, 2 wet services/yr, 2 dry services/yr and priority access)

The standard warranty offered by Hitachi is similar to the one offered by Daikin, which is 5 years of warranty on the controller and 10 years on the compressor. Hitachi however sets itself apart by providing optional 5-Year Comprehensive Warranty at a nominal fee of 299 + GST. This is a long warranty with gas charging, yearly wet and dry services and priority service access, a value added service that Daikin does not yet match at this price.

Daikin vs. Hitachi Maintenance.

The service of all of these air conditioners is reduced to a few major points, namely, the filters, the heat exchanger, and the condenser coils. The cooling performance and energy efficiency will also significantly decrease with time unless it is properly maintained.

To keep the Daikin in good condition one should…

1. Wash the PM2.5 air purifying filter after every six months. Titanium Apatite Deodorising filter is reusable.
2. The Dew Clean Technology (on 5 Star models) is automatic in cleaning the heat exchanger, although it is advisable to have a professional service performed at least once a year.
3. Keep watch on the Triple Display of auto error codes and filter clean indicators which warns you when it needs some maintenance.
4. The DNNS Self Heal coating on the copper tubing of the indoor unit minimises the requirement of cleaning the coils on a regular basis, but yearly inspections are still necessary.

To keep the Hitachi in good condition, one needs to maintain it in a proper way.

1. Clean or change the anti-bacterial mesh filter on a regular basis. The filter clean indicator of the indoor unit will remind you when it is time.
2. Periodically clean the iceClean (FrostWash) option by pressing the special button on the remote to clean coils on the inside unit.
3. The Auto Coil Dry Technology is an automatic process that occurs following every cooling cycle to avoid the build-up of dust and the growth of microorganisms on the coils.
4. When you have selected the 5-Year Comprehensive Warranty, Hitachi will include 2 wet services and 2 dry services annually in the package.

Daikin and Hitachi both use R-32 refrigerant that is easily accessible and is environmentally friendly and has no ozone depletion potential.

Daikin vs. Hitachi: Which is the more valuable one?

Which one should you incline towards the Daikin or the Hitachi should you want the absolute best bang to your buck?

Well, as you may guess, it all depends on what you are seeking.

These two manufacturers have premium inverter split air conditioners that are produced using quality materials and that suit the demanding weather conditions in India.

The following is a price comparison of all the models:

In case you are aware that you require something that fits a medium to large-sized room (111-150 sq. ft.), then you might want to consider either Daikin or Hitachi 1.5 Ton. The Daikin in the 5 Star category is around Rs. 1500 cheaper than the Hitachi, with a slightly higher ISEER rating and a lower noise level of operation. Daikin has the value advantage in this segment.

The pricing in the 3 Star 1.5 Ton segment is once again similar with a difference of only Rs. 500. In this case, the annual energy consumption is a bit less in Hitachi although the ISEER is also a bit less thus, the two brands are almost equal in terms of value.

In smaller rooms (up to 110 sq. ft.), the 1.0 Ton 3 Star models of the two brands cost nearly the same of approximately ₹31,500. At this price, it is a matter of preferences in terms of features and not cost.

Top Daikin models of medium to large size would consist of:

• Daikin MTKM50XV16 (1.5 Ton, 5 Star)
• Daikin MTKL50XV16 (1.5 Ton, 3 Star)

Best Hitachi models in medium to large rooms would consist of:

• Hitachi RAS.V518PCDIBT (1.5 Ton, 5 Star)
• Hitachi RAS.D318PCD2BS1 (1.5 Ton, 3 Star)

In case you can do with a smaller capacity, then you might consider the 1.0 Ton of either brand. They are also smaller and much cheaper than the 1.5 Ton versions.

Air Flow Comparison (Daikin’s 16 m vs Hitachi’s 24 m)

One of the main differences between Daikin AC and Hitachi AC is their airflow technology which affects how well the cool air is distributed in the room. Daikin AC uses Coanda Airflow and 3D Airflow for multi directional cooling while Hitachi AC uses 2 way swing although 4 way swing is available in newer models.

Airflow refers to the volume and direction of air an aircon circulates to ensure uniform temperature distribution. How does this affect overall cooling performance? Daikin’s Coanda Airflow blows air from top to bottom and corner to corner with 3D Airflow and 2 flappers for left to right circulation.

Hitachi’s 5400FXL RAS.G518PCBIBF has only 2 way vertical swing limiting horizontal distribution although their latest 5400STXL RAS.G518PCCIBT has 4 way airflow for better reach.

The advantages of Daikin’s airflow system are superior corner to corner cooling which means consistent temperature throughout the room. This improves air circulation and prevents uneven cooling or hotspots. Plus its optimized 3D Airflow provides a more immersive cooling experience perfect for bigger spaces.

Compared to Daikin’s advanced airflow technology gives you more uniform cooling across the room creating a more comfortable environment than Hitachi’s older 2 way swing system.

How loud are Daikin and Hitachi AC’s?

When it comes to noise levels, Hitachi AC performs better as it has lower decibel readings at all speed levels. Daikin’s 1.5 Ton models (MTKL50U and MTKM50U) has 48 dB on high, 43 dB on medium and 38 dB on low.

Hitachi ACs with wave-designed blower has 50 dB on high but drops to 40 dB on medium and 34 dB on low. That means at lower speeds, Hitachi is noticeably quieter, it’s a better choice for those who prioritize minimal noise especially during nighttime or in quiet areas.

Note that real world noise levels can be affected by installation quality, room acoustics and maintenance. For example even a quieter AC can sound loud in a small, echo-prone room, while a well installed and insulated unit will further minimize noise perception.

Hitachi’s silent air technology which has a large wave-designed blower reduces airflow noise significantly. So even when the unit is running the sound of air movement is softer compared to traditional designs. Daikin’s swing inverter compressor minimizes operational noise but might be slightly louder at higher speeds.

Copper Pipes Comparison

Daikin’s indoor unit has copper coil. Its fins will also be visible without coating. And look at its C-bands and U-bands, there is a chemical coating on both evaporator and condenser coils of Daikin so that sediment and salt won’t accumulate on them. But the company says we do anti-corrosive coating.

Now it’s possible that they do the transparent one. After that I will tell you about the insulation.

You won’t get any coating on the pipes. Here you will see it’s a double row copper coil.

In Hitachi, AC’s I have seen they also providing double row copper coil like Daikin, you will find anti-corrosive coating, they are calling it “powder coating” on the copper pipes.

Daikin or Hitachi: Which one to buy?

Ok so all said and done, to the point, do you buy the Daikin or the Hitachi air conditioner?

The Daikin may be best if you:

• Want the quietest operation: In all similar models, Daikin always operates quieter than Hitachi. The Daikin 1.5 Ton 5 Star has a noise of only 31 dB(A) as opposed to 37 dB(A) of the Hitachi, and thus the Daikin would be more suitable in bedrooms, study rooms or any other area where noise is an issue.
• Need the highest energy efficiency: Daikin has slightly higher values in both 3 Star and 5 Star (5.7 vs. 5.6 and 4.4 vs. 4.3). Although the difference is minimal, it would lead to reduced energy consumption per year and savings on electricity bills in the long run.
• Requirement of extreme heat performance: The 5 Star models of Daikin have the ability to retain their full cooling capacity at 46 °C, and can operate at temperatures up to 55 °C, which makes it superior in the hottest parts of India where ambient temperatures often exceed 43C.
• Want high-tech self-cleaning: Daikin Dew Clean Technology will operate automatically, but the iceClean by Hitachi will have to be turned on manually. Daikin is more suited in case you want a more hands-off approach to maintenance.
• Prefer a cheaper price: Daikin is 1.5 Ton 5 Star around Rs. 43,990, which is about 1,500 cheaper than the similar model of Hitachi.

The Hitachi may be best if you:

• Desire increased cooling capacity: The Xpandable+ technology in the Hitachi can provide up to 110-112 percent of rated cooling capacity when the demand of the conditions requires it. This additional cooling capacity may be felt in a place where the heat is excessive or in a room that is always hot.
• Want more airflow control: 4 Way Swing and 24m long air throw in the Hitachi mean that the air gets to all the corners of the room, both horizontally and vertically. This is especially applicable in bigger or irregular shaped rooms where even distribution of air is a problem.
• Desire custom presets: The My Mode feature of the Hitachi allows saving up to 3 custom settings with your favourite temperature, fan speed, timer, and silent mode settings. It is a convenience option that is not provided by Daikin, and hence Hitachi is an option when the family members have varied preferences regarding cooling.
