For a moment I thought that Hitachi had rationalized their pricing but somethings do not change. On going through the tech specs for the new machines introduced this season including the one above it is clear that the machines are not really 1.5Ton which roughly equates to 18000btu/hr. These machines are rated at 17300 btu/hr for the QC summer, 17000btu/hr for Kaze and 17060btu/hr for the QC TM models. This is going to show up when May and June roll in and bring with them never ending afternoons with sustained temperatures in the 40 C + range.

You would be better off looking at the Whirlpool with compressors rated at 18000 or the General window unit offering the 19781 btu/hr rated compressors at similar to and slightly higher than Hitachi's price point respectively.

How would it be compared to an LG? I was also looking at a similar priced LG 5 star split (this one: LG LSA3ER5N Split AC - Defining the art of cooling with Jet Cool , Selectable 4 way air swing, Triple filter, Auto Clean, Virus & allergy safe filter, e-Saver. - LG Electronics IN VS Sharp: Sharp )

Thanks again.
You know one would be thankful if instead of asking questions like the one in bold above, you guys would take the time to just browse through the last few pages of the thread pertaining to the ongoing season's posts.

I needed an AC for my second bedroom and finalized a 1 ton, 2* Samsung split unit, as the usage will be only for ~ 6 hours a day. Bought from Ratna Fan House for Rs 21490.00, price inclusive of stabilizer and installation.

I already have a Samsung window unit for the past four years and am very happy with it.

Post Voltas

Thought I'll add my two penny bits to this

I own two ACs an O'General 1.5 years old and a Voltas 1 year old. Both 1.5 units.

Do not like the O'General much. Its a great AC, very powerful but I've had the remote going dead on me twice and the AC started malfunctioning once. The fan would shut off but the compressor would be on and at it.
I was as bugged with all this than I was with O'General's Service in Delhi. It was an outrage.

The Voltas Platina has been kick *** so far. Powerful fan, powerful cooling, frugal on electricity usage, very silent and built to last.

Like many of you guys here I used to think that O'Gen's and Hitachi's and Daikin's are the best but they come at a price and I am really not sure how good they are.

PS - I have used Carrier machines as well and they are trash!

The above statements are based on my opinion. Please do not get upset with after reading it.

Cheers!!!

I know what you mean. I did actually search this thread for Sharp but didn't find anything. I also read about the LG brand but I wanted to know more about that specific model since its from a new range.

Anyways, thanks for the suggestion once again. I've bought the Sharp! Will be installed tomorrow.

PS: The only thing I didn't like about Sharp AC is that there is no temp. display on the unit (I think) and the remote looks pretty basic. But I'm sure the AC itself would be very good.

Rather than getting upset, such feedbacks are valuable though a bit more detail would be welcome.

@goingout. There is a lot of feed back on LG, as you also have noticed. As for the recommendations for the new models being offered this season, one would be able to comment on them only after gathering appropriate feed back from the service technicians, installation teams etc. This will only be possible towards the end of the current season or even later. Untill that happens it is safer to spend your money on products that have been tried and tested.

As for the temp. display on the unit that is a non issue and usually found on lower end machines to offer the purchaser with an in your face but useless feature. One, it is difficult to read the temp display on the wall units from a given distance and secondly & more importantly it involves an unnecessary electronic component on the unit. It is best to have the display on the hand remote.

The way I look at it is that the differences between the top brands may be marginal. Two parameters which will come into play is the service quality of the vendor (splits may need attantion more than window units) and also (esp. for coastal areas) whether the condenser coils are copper or aluminium.

I have seen it on some high end models as well. My dad finds it easier to read the display on the AC unit rather than on the remote. Even I find it useful to alter the temperature or timer at night time since the display on the unit is LED. If it were on the remote, I will need a light and disturb others.

Yes I think it completely depends on your personal preference.
My two year old Samsung split AC has as very nice remote and display on the unit but some LED digits on the unit stopped working just after the warranty ended (like in less than a week lol).

I personally think temp. display on the unit is quite important. I'll check today if mine has it or not.

Thanks

The temperature display both on the AC and on the remote is just what you have set, and not what is detected. It is as informative as the angle of the thermostat in the older AC. My Window AC has it, while my Split does not, it makes no difference as you need the display only when you change the settings; which is normally done via the remote; and in our case less than once a week.

I have seen two displays on some AC, one for the set temparature and the second one for the detected temparature. That makes a lot of sense, as you can track the cooling and fine tune the room insulation (doors constantly opening) to achieve best cooling.

That is right, what the unit displays is only the intended temperature, not the actual one. The latter is reached when you hear the compressor cut off, at which point both are the same! BTW irrespective of what temp you set, the grill temp of the air that comes out is the same (usually about 16 - 18 degrees).

What I meant was, sometimes I have to increase the temperature during the small hours if someone in the room feels cold, for which the LED display on the unit is very useful. If it was only on the remote, I will need to switch on a light or at the very least use a flashlight.

Out of our three Samsung ACs, one has an on-unit temperature display. It displays both the set temperature and the detected temperature. This is the sort of feature that would, I admit, look good to me in the shop! Whether it is particularly useful or not I can't say.

The most useful indicator is one's one comfort, and, second to that, an independent thermometer showing the temperature in the room away from the unit itself. If the thermometer is digital, it might display humidity as well. This is a major factor in our comfort (possibly more than actual temperature?) but the AC manufacturers haven't thought of building in a feature to display it.

Another factor of on-unit displays is that some of us like our bedrooms to be dark at night, and such a display can give a surprising amount of light.

I know that the maximum temperature setting is 30C, therefore, in the dark, if I press the temperature-up button five or ten times, it must have reached 30, and I can count down from there. I like a night-time temperature of around 28: those who prefer something like 18 could reverse the idea, and work up from the remote's known minimum.

@Thad
I have a digital wall clock in the room, which displays the temperature. The readout of this clock and that of the AC is off usually by half a degree. The clock shows a higher temperature.

Default Re: Which home/office AC (air conditioner) to buy ?

guys, i recently got the voltas 3star window AC (1 ton).

AC - Rs. 16600
stabilizer - Rs. 1900 (Bluedart)
installation Rs. 500

wiring - extra Rs. 650 :(

total ~ Rs. 20000
The AC is working good but i got an issue. The compressor stops every 30-40 mins for like another 30-40 mins and till that time the room temperature becomes the same as it was before. Y am i not getting continuous cooling? Is there any feature like temperature control/time control etc which i have enabled unknowingly? please help. this is really irritating.

Try changing the thermostat setting. In my case I get the same behaviour at around 25 degrees, but any other temparature the unit behaves impeccable.

Another reason may be that the temparature sensor is touching the cold coil and it takes time to register the warming up of inlet air. In this case just move it a bit away from the coil and your problem is solved. (If the sensor is touching the coil the moisture can collect on it and at time it freezes, so till it thaws it thinks that the air is cold!)

He is right in saying that more current is drawn during the 'on' operation compared to flat out running. However he is incorrect in saying that a slightly smaller capacity is the way to go. This is like using a 10 ton capacity truck to carry 15tons. The reason he propagates that is to keep the compressor running to avoid the off and then the energy sucking 'on' operation.

The inverters also avoid the off and on but in a different manner. Once the desired temp is achieved the inverter mechanism slows down the compressor that is the RPMs or the SPMs (rotary/reciprocating respectively) are reduced. This allows the unit to hold the temperature constant and avoid the off on cycle. This infact will get better results than a lower capacity unit running full steam all of the time and also result in much lower wear and tear as the unit is able to run much lower speeds once the initial load has been met with. Further on the flip side during situations when the load is higher than usual a properly sized inverter will be able to increase the speed of the compressor to meet the increased demand where as the undersized machine will huff and puff all it wants and yet leave everyone uncomfortable in the process.

Trust that answers the query.


Please see my comments in bold within your post




That is one keen salesman. It is a great idea.






A cousin has a couple of these two in one machines (with the heat pump) and they work great.

I myself have three 9 fin Delonghi's for our bedrooms, varying between 160 and 125 sq.ft and one 11 fin Usha lexus for the tv/dining area + living room both rooms being approx. 240~280 square feet. The bedroom units are good to go through with the worst of winters, the larger rooms however do need a 9 fin unit in addition to the 11 fin unit during the coldest parts of the season say December 3rd week to January end.

The thing is that the Delonghi units are no longer available after the ruling necessitating the ISI mark to be present on all electrical items being sold in Dilli was implemented. I checked a lot of other brands in the market last season but eventually found that the Usha lexus was the best thing going. Having siad that it is not a patch on the stuff by Delonghi. In this scenario you would be better off getting the heat pump units. BTW have you bought water heaters for the next winters?

The only negative that these machines have is that they can cause dryness which the oil filled radiators will not. This is based on the experiences of my cousin and his parents who run these machines in their bedrooms. My aunt and uncle are more uncomfortable compared to cousin and his wife, guess that is due to the age differential.

Talk to the Daikin guys and try get the 'Ururu Sarara' machines. Three is a good no. to bargin with and the carrot of an additional two will only help smoothen things out.
khoj,

thanks for sharing the experiences.

Dealer says 'Ururu Sarara' not available in India.

1. what about the water heaters ?


so are saying that the Usha lexus cannot perform at the same levels at as the Delonghi and wont be able to warm up a room comfortably.

this is my situation.

i can go with 1.5 Ton.

1. Inverter Hot & Cold @ 67000 ( inclusive of stab, installation, pipe etc. )

Total Cost for heat & cool = Rs 67000


2. Inveter Cool only @ 45860 ( inclusive of stab, installation, pipe etc. )

+

Usha Oil Filled Heater @ 9000 to 12000

Total Cost AC + Heater = Rs 56000 ( rounded figures )

Difference between option 1 and 2 = Rs. 11000


So as you can see for Rs 11000 more i have following advantages


1. Single unit for both hence neater and cleaner arrangement.

2. No need to allocate space for the Oiled filled heater and no need to worry about storing it away during summers.

3. I'm assuming the Inverter based heating will be more cost efficient with lower electricity bills than the Oiled filled heater. ( need clarification )

On a cost of three 1.5 ACs with Inverter Cool + Heat this will be an added cost of around Rs 33000 over a three AC + Oiled filled Heater combination.

I'm a little hesitant to make a decision. But i have to make a decision for sure within the next 24 hrs as the heat is already unbearable.

Khoj, What do you suggest ?

Thanks
