Hitachi Window Air Conditioner (AC) Review

Hitachi Home & Life Solutions India is a subsidiary of Hitachi Appliances Inc, Japan and is one of the leading air conditioners manufacturers in India & Worldwide. Headquartered in Ahmedabad, Gujrat, the company has a major manufacturing plant in Kadi, Gujrat which is among the ten-Hitachi air conditioner facilities worldwide. They have been highly competitive in the Indian Market by selling a premium range of Air conditioners which are best in looks when compared to other’s manufacturers in this sector.

Hitachi Window Air Conditioner (AC) Review

Hitachi offers only a premium range of ACs in Indian Markets. That means they are the costliest air conditioners and its price range gives competition to O’General ACs. But premium cost doesn’t mean they expensive because of brand name, but its because they offer lots of features which makes them expensive but still cost gets justified when you buy brands like them or O’General because they have a very long run. It’s like a one-time investment and forget it. However, timely service and proper cleaning is a must to run a product for a long time efficiently.

Hitachi Window Air Conditioner (AC) Cooling Effectiveness

Sirocco Fan, Propeller Fan, Turbo Fan
Sirocco Fan, Propeller Fan, Turbo Fan

Hitachi AC’s are very effective when it comes to cooling. The cooling rate is good and the room gets cooled up quietly fast. These AC’s have a Twin Turbo Technology which increases the heat exchange when at high temperature and ensure an optimum cooling by not even overloading the machine capacity.

The advantage of Twin Turbo Technology is that it is designed to throw air in both directions and provide higher air-flow at lower RPM, however in conventional AC’s, Sirocco fans are used on the inside and outside propeller fans are used, and these fans by design can’t throw air in both directions and hence lower efficiency on those. And due to the presence of a large number of blades, the air cutting noise is high resulting in high noise levels and lower efficiency. That’s why the number of blades presents inside in Hitachi window AC’s are less, so this results in less cutting of air and hence more effective cooling. And hence due to use of Turbo fans inside and outside, the person gets an increase on overall air-flow leading to higher efficiency even at lower noise levels.

Hitachi Window Air Conditioner (AC) Build Quality

Build quality of these AC’s are very impressive. And it should be as they are charging a premium cost for them. The front frame is made up of good quality plastic and doesn’t give any cheap plasticity feeling. The frame is one of its kind and is unique to this company design. Overall finishing of the product is very fine and one must check the product from each corner while buying it. Because when the company manufacture a product, it passes through every quality check, but the only thing which is not very traceable is transportation. So, one must check the product from every side and corner, that it must not have any single dent on it. If it has, never buys it.

Hitachi Window Air Conditioner (AC) Looks


Hitachi is the one which I think is a leader when it comes to looks. This company is famous for making the best looking ACs in its range. If your the one, for who looks really matter with quality as well, I would definitely recommend buying this. Hitachi window AC’s comes with different product ranges like Summer QC, Summer TM and Kaze. Summer QC and Summer TM are those range whose looks for Hitachi is famous for. Its design consists of air blowers at two sides with coil grill at the middle. The design looks super fabulous. Whereas KAZE range design is what has a basic design, have fewer features and are less expensive then Summer QC or Summer TM.

Hitachi Window Air Conditioner (AC) Power Consumption

This is one more big point, for which Hitachi is famous for, manufacturing highly power efficient air conditioners. This point matters when we run ACs in the long run. There is every type of customer outside in markets. One who uses air conditioners for a few hours or there is few who use it a whole day like at commercial places. When you run the air conditioner for few hours a day, you won’t be really able to judge if its really power efficient or not, but when u run it for a long time daily, this is where you need a real power efficient product and Hitachi can be chosen as one for it.

Also a very impressive and unique feature it has inbuilt Power Index on the control panel which indicates the relative power consumption at different AC settings and hence you can keep a check how much power it is consuming and you can lower your electricity bills by running it at most power efficient settings. And always remember, higher the BEE star rating, more power efficient the AC would be. Have a look at the following chart which would make things real clearer about the power consumption by these ACs.

Hitachi Window Air Conditioner (AC) Features

  • Twin Motor Technology

In Conventional AC’s, usually there is a single motor to run both indoor and outdoor fans, hence when we reduce the fan speed of inside, it eventually reduces the outside fan speed as well. This reduces the air conditioner ability to throw hot air outside and impacts the overall efficiency of the AC.

Whereas in this AC, there are two independent fan motors, one for inside fan and other for outside fan. Which means the inside fan speed is independent of outside fan and hence the ability to throw hot air outside remain unaffected. Thus how overall efficiency of the machine remains unaffected. This feature is available only in the Summer TM model.

  • Auto Climate Technology

Every type of customer has its unique kind of requirement and comfort level in different weathers. For Example, in Delhi, its the month of June or July at which temperature touches 44 deg C or more with a humidity level of 60%, whereas in Mumbai, at the same month, the temperature is around 35 deg C with a humidity level of 85%. Hence when we have any regular AC, we control these factors by changing temperature and regulating the fan speed. But then choosing the right temperature and fan speed at different temperature with changing weather and changing the level of humidity makes extremely cumbersome to choose the right settings every-time.

That’s why, Hitachi window AC has a super-advanced intelligent feature that has temperature and humidity data of over 100 cities fed into it. The AC recognizes which city you’re in, the time and the individual metabolic needs e.g. hot, very hot & humid (to be chosen by you). Based on these factors, this AC continuously change the setting accordingly to maintain a comfortable environment, which functioning most efficiently at the touch of a button. This feature is available in every model.

  • Digilock

If your AC is being misused in your absence by children or by anyone, then just turn on the Digilock, it will lock your AC and prevents the misuse in your absence without affecting your comfort settings. This feature is available in Summer TM & Summer QC models.

  • Alarm Function

If you’re too cosy to leave your bed on time, then this AC has got an inbuilt alarm to wake you up and it automatically turns himself off on time which you set. This feature is available in Summer TM & Summer QC models.

  • Supercool Function

When turned ON, this function sets the AC to work at its maximum, so as to maximize cooling in short span time. This function is available in Auto & Cool mode. This feature is available in Summer TM & Summer QC models.

  • Koukin Filter

This unique anti-bacterial filter prevents the growth of bacteria inside the air conditioner and ensures optimal performance of the air conditioner every time. This feature is available in every model.

  • On/Off Timer with Advanced Start-Up

This AC gives the option that you require a particular temperature at a particular time daily. For example, if you 24 deg C at 09:00 PM when you come back daily from office, this AC is smart enough to scan the room as per your need. It will scan the room at 08:00 PM and will calculate the time required to reach the desired temperature and switch on itself accordingly. When it attains that required temperature, it turns off back without wasting any electricity and you the desired comfort when you come back home. This feature is available in every model.

On-Off Timer with Advanced Start-Up in Hitachi Window Air Conditioner
  • Extra Heat Exchanger (XHE)

Mostly window AC’s are air-cooled whereas this AC has an extra Heat Exchanger attached to the coil which is cooled by the condensed water. Water cooling is definitely better than air cooling and hence it automatically increases the air conditioner ability to throw hot air outside enabling it to perform efficiently even at very high ambient temperatures. This feature is available in Summer TM & Summer QC models.

  • Kaimin

Have you ever woken up feeling chilly in the middle of night? This is because when we run the AC whole night, it even attains lower temperature than what we need and set. To tackle this problem, it has a unique feature named Kaimin, which is quite intelligent to provide you a sound sleep by raising 1 deg C temperature per hour for up to 4 hours. This helps in retaining a required temperature in the room and this also helps in saving of power too. This feature is available in every model.

  • Filter Clean Indicator

This indicator reminds you when to clean the filter through LED on the indoor units. This feature is available in every model.

Hitachi Window Air Conditioner (AC) After Sales Service

The reviews we collected for this AC after-sales service are not very impressive. If you live in metro cities, you can buy this with closed eyes as big companies have got big competition in big cities to survive and after sales service is one of the major factors while buying an air conditioner in consumer mind these days. Hence, in metro cities or famous cities, you can buy it without any problem, but for other places, after sales service are not very promising, however i am not saying that it is that bad that you may not purchase it. Hitachi just needs to improve this thing and need to step into social networking as well to create more brand awareness and to win trust of consumers.

Please note that all prices given are approximate. Please check your local dealer to get most competitive prices. You’ll definitely get a difference of Rs. 1000 to 2000 (may be more or less). My idea to get best price is to call JUST DIAL and tell them that you need to purchase a window AC. Then you’ll automatically start getting calls from dealers nearby you and you can choose from the one who is offering you a competitive price. If possible, buy it from a authorized dealer only.

Final Verdict

Hitachi up to my knowledge is the only company who offers a whole list of features in their air conditioners. They have got some unique features which no other company is offering currently in India. So, just in case, if all the features i explained above have impressed you, go ahead and buy this product. But do get some local reviews if possible about how is the after-sales service in your state or in your area of this company. And when it comes to product life, it is definitely a good buy.

An optimist to the core, I always see the glass half full. I like to take life as it comes and not to become too serious on the harsher aspects of it. Apart from this, I am an Engineer, a Blogger & a Researcher....

  1. Can you let us know how to turn off the filter clean indicator.. the manual instructions doesn’t seem to be working !.. neither the call center is supporting in this. Hitachi has a ridiculous after sales service. I am not sure how you give them such a positive verdict !.

      1. Dear Hari, Please take your complaint forward to your nearby Hitachi service center. Thanks

  2. I feel that a lot of people are getting the Filter clean indicator within a short span of time. My Ac was installed around April mid and its already giving clean filter indication in Jun mid. .. in just 2 months!!!

    Is this some kind of fault in the units!? Mine is SummerTM 1.5 ton 518ESD unit.

    1. Filter clean indicator gets ON every 100 days in Hitachi AC’s. So, all you need to do, is to open the AC, clean the filter, put it back and press the filter clean indicator again present in remote. Then this indicator will remain off for next 100 days!! This is not a problem, people are just not clear about its functioning.

      1. The filter indication is in orange colour in a batch of Hitachi summer TM ac’s. It should be red. All these displays need to be changed. They are doing it slowly. Most probably, in about 15 years time, they will clear this years backlog.

      2. thanx a ton, worked like a charm…i was getting pissed off

        One more thing, compressor sometimes switches off with a heavy sigh…sometimes very smoothly
        Also, compressor gives sound like trrrrrrrrr when working….mostly on outside that comes inside also…looks more than normal…dunno it’s a little closed space outside so may be sound coming back

        Cooling is so good that it can’t be better

  3. filter clean indicator is not going after cleaning the filter and pressing the filter key in remode.
    what to do?

      1. I am facing the same problem as Gaurav. The manual supplied with the AC is of older models. The clean filter indicator just doesn’t go. The customer care has no solution.

  4. my complaint no is 12070400178 which was registered on 04-07-2012.
    Since then I trying to get my ac repaired but of no avail . I
    contacted everyday to so-called customer call center, twice/ thrice
    but nothing is done till 11-07-2012.People attending calls don’t have
    any information except to say for tomorrow.Was it my fault to purchase
    a Hitachi ac ? Worst after sales service experience in my life.

  5. i want to know what is the electricity consumption of hitachi 1.5 ton 3 star kaze air conditioner in one hour please tell me accurate answer

    1. Dear Gian, it is impossible for me to tell a very accurate answer, but as per standard calculations, this air conditioner will consume nearly 1.75 Units of electricity per hour. Hope that helps.

  6. Hi I live in Delhi NCR and i choose to disagree that one should buy the AC blindly. What good is a AC if its parts are faulty and you can’t get spare parts. Buy a AC where you can get a spare parts. My AC has gone faulty with PCB and Motor and its has been a month without any spares and lots of calls to local vendors and hitachi. Regret my mistake big time.

    1. Dear, please read comment of RG Hegde in this page. He also faced similar kind of problem but was resolved later on. Check his comments and how he got resolved. Thanks

  7. My Hitachi AC RAW318KSD has a very annoying noise when the compressor gets started. It’s like someone is shaking the AC very badly.
    I have called HITACHI service center, the person came to check and said that the noise comes with HITACHI.
    Is it what a Big Brand “HITACHI” is offering it’s customers.

    1. Lokesh, please check if your air conditioner is installed properly. Also if there is proper insulation around air conditioner which may absorb the vibration. Get your installation checked by local vendor person.

  8. selecting series of hitachi window ac

    Can anyone suggest which series (summer QC / summer TM / Kaze)
    is better.


    ve just ordered a SUMMER TM 1.1, 5STAR AC after reading your review. However, i had missed the comments part wherein HITACHI owners have given great reviews about the UNPARALLEL & FABULOUS AFTER SALES SERVICES. i seriously hope i have’nt made a wrong decession.


  10. I m planning to buy Hitachi Window AC 1.5 Ton 2 / 3 star kaze plus . I little worried about the after sales service when i go through the comment given by various customers. Plz recommend me , is it value for money OR you recommend any other Brand / company AC in place of Hitachi .

    1. Even i bought kaze plus 1.5t 3 star… Cooling is osum… But vry noisy…. Same with urs? I reg a complain .. Will let u knw if prob solved

  11. help

    i had read complaints of all ac brands i am confused now
    can u tell me which ac company and brand is best including all ( serivce as well colling )

    i live in delhi want to buy 1.5 tone window ac

  12. Not at all good AC avoid buying Hitachi . O-general is 100 times better then Hitachi if u don’t be live and see a demo of both AC and also see the compressor u will find the diff..
    Plz plz pl don’t waste ur money just see the demo and then decide urself .

  13. Filter cleaning frequency & reset

    The air filter has to be cleaned every 100 hrs of operation, not 100 days. A red light appears on the unit as a reminder. Cleaning is quite straightforward. Plastic mesh filter can be dusted and washed simply. Once replaced, the indicator has to be reset by holding the bottom right button on the remote. That turns the light off for another 100 hrs of operation.

    Hello Ankit

    Nice info on ur page however I missed it be4 buying QC/1.5ton/5 star model :)
    Had a query. The first night I switched on the AC, it consumed around 28 units, I checked in my electricity meter. AC ran for 6 hours in Auto mode(power saving mode)displaying CA on the monitor.

    Now I m using the AC in Cool mode and for around 4 to 4.5 hours and the units consumed are somewhere around 15 plus

    Is that fair or you have some different experience?
    Request ur expert comments.

    How much units does this model consume per hour?
    Does reducing the temp say to 16 C consume more units?
    Best mode and operating techniques for least consumption of units?

  21. Modes of Hitachi Summer QC

    I want to know the different modes of Hitachi Summer QC 1.5 ton. It’s very easy to read them on the blog but can any one explain as what sign indicates what? Like for example, the 5 modes displayed on the panel are (1) AA, (2) d_, (3) c_, ()4 Fan, (5) P5.. Out of these Fan is understood but what does the rest mean? There are 5 buttons on the display pad: 1. To Start On/Off, 2. Modes (which changes the above mentioned modes), 3. (Fan Speed), Temperature Up, 5. Temperature Down. Nothing where it says how to set times like it is with Voltas Verdant. It is one of the best AC available in the market.

    1. the AA mode is auto mode. you cant adjust any thing machine will take care all about and temp. set will be 25 C.

      2nd mode is C_. you can set the desired temp and machine will take care about all other things to obtain the desired temp.

      the d_ mode is dry mode and may be useful in humid condition.

      F mode , you are well known.

      P5 is powerful mode and compressor will run about 30 minute continuously to cool the area more efficiently.

      All the modes are almost predefined to help the user in one click so that he can enjoy and not finger the machine.

Please advise.

    2. cheating by dealer

      I bought 1.5 ton Iclean model Hitachi ac in may. 20 days back red light started blinking, the service engineer visited and informed that dust collector is not there in the unit. When I contacted chennai hitachi office and dealer (air sakthi) both of them demand money from me to pay for the dust collector which was not in the unit and is the fault of hitachi.
      I need dust collector to be fixed free of cost as unit was fixed by dealer and was opened for service by hitachi technician
      my contact number 9884224020

  26. I fully endorse that problem with Hitachi is just selling bad product RAT518ESD. My other some more than 10 year old Hitachi products have not let me down. after 14 months i have an E9 error and once i also complained in warranty that the fan is noisy and bad, they did nothing. Now i will spend a fortune to get the motor replaced and again in fear that it will go bad in 14 months. They are just dumping untested products it seems. the net is full of complaints on twin motor


    Never buy hitachi product..I bought 5 star ac ,within 1 year it started having problem .no-one from service centre turned up for 15 days.then after 15 days i got to know that the DC motor of ac is not working .Many customers in my local area had same problem with there ac within 1 year.Parts are not available by Hitachi so my ac has become a showpiece.They dont pick your phone as if we are begging them.Do you Guys Also wants to buy such fraud product with no use within 1 year..BELIEVE ME.DONT GET TRAPPED BY HITACHI PRODUCT
    My complaint no. was 13080102455.(better go for other ac of any brand ,it will be cheap and u will get good service)

  28. Hitachi is the Worst AC

    These are the worst people you can buy ACs from. HORRIBLE HORRIBLE HORRIBLE after sales service. HORRIBLE product. You will repent terribly if you buy their product. At the time of purchase they will make huge statements and prmoises but its all bull shit.

    We have been having an issue for the last 2 months. There is no one to address irrespective of how many mails you write to or service complaints you log. Their Facebook page is full of criticism of their products and services but they remove those posts and block the people.

    They are not even man enough to accept their faults, drawbacks and inefficiences.

    Last warning to all fellow consumers, you buy their product and it will be the worst mistake of your life. Try and see!!! You will cry for the rest of your life.

  38. Hitachi 1.5 window AC motor

    I purchased Hitachi Window 1.5 ton AC in 2012. Last week it showed E-9 problem. Since I had bad experience with the service of Hitachi service station, I asked local electrician (AC specialist) to check . He repaired the PCB and the AC started working but next day same problem came again. Now after one week of searching a DC Motor ,he replaced the Motor yesterday and the AC is working now. He has told the cost of motor as 7200/-. I could have believed,had he showed me the bill/motor cover but he says that it is original and cost is actual.
    Kindly let me know if I should believe him and pay.

  43. Hitachi customer service is bad

    I booked for service of my Hitachi window AC on 13th May. Inspite of repeated emails and reminders no one from Hitachi is responding for attending to the request. My experrience about Hitachi is that it is unnecessarily expensive and is useless when you need to get it serviced.

  44. Worst Customer Service

    This have been the worst customer service experience I ever have to go through and hitachi was the last brand name I expected this from. I purchased an hitachi window a/c from vijay sales New Delhi(Janakpuri) in the month of april,2015. In the month of august on 26th to be presious which was wednesday the a/c gave me the problem for the first time, It just stopped working. I did what I was suppose to, I registered a complaint with the company. The next day the technician came to check the problem and told me that the a/c panel is not working. So now he tells me to send the copy of an invoice on a particular e-mail address after which the new part will be issued by the company and the technician will come and set things right. All this was suppose to happen the very next day as I did mailed the invoice. Now first of all the technician who was suppose to change that particular part of the a/c didn’t visited until 31st of august i.e monday and when he did I am not sure he knew what was he doing. Even though I got the new stablizer that particular day according to the technician it was faulty, later after checking properly the connection that he did with the stabilizer was not right. After rectifing that connection he started blaming the power plug but even that also turned out to be ok. Finally he had to admit that the new panel that he brought which was suppose to replace the broken one was also not working ( arey sir yeh toh naya panel hi kharab hai). He could have easily gone and get the new panel at the same time and replaced it but even after we requested to do that rather than understanding the inconvenience we have been going through he decided not to worry about that and make the changes next day, which brings us to today i.e. 1st sept. Well even today he decided not to show up although i have been following up the support guy since moring, this makes it the 7th day. This whole thing have been nothing but the great inconvenience. I am really disappointed with the company. I mean I am ok with the fact that the a/c faced the problem, but what I am not ok with is the after sale service. I purchased the hitachi a/c for it’s brand value, supposing such a big brand what would ever go wrong and if somthing happens the company will help but I suppose I was wrong. Well one thing I am sure about is I am not buying any hitachi product ever again let alone advising it to someone. I’ll appriciate if I can get a response on this on the e-mail I have given above.

  45. Worried on Hitachi

    Hi, I have just booked Summer TM model, simply because two of my friends have Summer models, and its the only 5 Star Rated AC I could find from an MNC. Question 1: Am I correct? I believe no one focusses on window AC anymore, and Hitachi has these last good models remaining.

    I am otherwise a Fan of O General, but I have Reliance Energy at my place, and they just want to take my enitre salary in electricity bill. I am not kidding! so I had to had to go for anything Window but 5 Star.

    Question 2: what would be roughly the difference in a 5 star rated AC and say O General? out of curiosity. percentage wise or so?

    Moving On, reading through the comments about Service of Hitachi – it seems that they are Consistent about Providing BAD service.

    Ankit, I stay at Mumbai, its very unlikly I will go to vijay sales and change my AC brand. but don’t you think that over so many years this kind of comments are coming for Hitachi, they should have done something about the Service.

    Not that say LG service is that great. I have a TV and at first they were poor and super slow at responding. but eventually it gets solved. someone in the chain listens and resolves. you yell at them – some work happens.

    In Hitachi, it though seems like its a Black Hole? no response is it? I really dont want to get frustrated that ways. I really like the Tech AC and its features.

    So if Hitachi’s Indian Team, their top brass guys are reading this or if you could forward the same to them. Let them show up on your blog, like they have done once earlier and prove a clean image!!!

    Who’s Listening?
    Thanks for a great thread on Hitachi AC, this helps a lot on Indian Web where mostly people are not genuine with blogs, serches and web pages. Thanks.

Now again in this summer 2017. I am facing problems with it of excessive noise and no cooling same problems with it of excessive noise and no cooling I lodged the complaints with the company. servicemen came and said that there is a problem with the unit, and and compressor need to be replaced. Its more than 10 days, we are following with the customer care and till date we have not received any message or input from company service center end. In this sizzling summer of Delhi i am not even able to use my A.C. So i will request everyone to, Pls stop buying Hitachi Ac’s, as they are willing to sell product, but not able to give services and making customer. As they are least bothered after sale of product.

  62. Hitachi window AC not working

    Hi Ankit
    My Hitachi AC is showing E9 error.
    Can you send someone to fix it?

  63. The product was very good in first season, when it was opened again in next season , the cooling was low. Repeatedly, lodged complaints within the warranty period, but of no avail, the technicians visited were untrained, without technical knowledge, not touching the machine gave their ex parte decision, even knowingly that that was no cut off no water dripping no proper cooling. Not satisfied with complaint escalation system. The product and after sell service is so pathetic that I am lamenting for buying this costly brand based on advertisements, so please think twice, thrice and times as you like before buying

  64. E9 error with fan motor and compressor working.

    The Hitachi Service Centre at Gandhinagar, have non contactable phone numbers and the location on Google map of one of the centre turned out to be a cow shed in a village, the centre wasn’t there. This shows the lascidal attitude of this Brand Hitachi. I had E 9 error on my RAV model and had got the Motor changed for Rs 12500 in 2017, the error appeared again in 2018 and this year the AC fan and composer are both working but it switches off after 20 mins of running and E 9 error appears. The fliter has been cleaned thoroughly but the light does not go off. Looking desperately for a Hitachi Service Centre in Gandhinagar , Gujrat.
