[skumar]

Best option - Mitsubishi Electric STARMEC 34,000/-
second Option -Mitsubishi HEAVY industries 1 Ton - 31,000/-
Third Option - Mitsubishi Electric MR SLIM 1 ton - 30, 000/-

Dinyaar - were these 1T or 1.5T? Thanks.

 

[goyal.sanchit]

Even I have heard about the good quality of Mitsbhushi in the recent days.



Also one thing I noticed here is that no1 mentioned Bluestar!!

How are they quality wise??

Dinyaar - were these 1T or 1.5T? Thanks.

These prices are for 1 TON SPLIT MACHINES.
Yes they are on the higher side. Plus they will charge u 3/7K (depending on the amount of wire used) for installing the machine preferably with SS brackets or a 'cage'.

My vote goes to O-General from grey market. (Not Made in India ones). Buy a MADE IN THAILAND O-General 1 Ton split. Its easily available in Mumbai, not sure about Kerala.
O-General 1 Ton gives equivalent cooling to 1.5 T of Samsung LG etc.

Quality wise DAIKIN is no. 1, but an overkill as suggested earlier by another member.

Thanks guys,
Looks like the really good ones which are quiet and efficient (Mitsubishi, Daikin, Hitachi costs around 30k or thereabouts.

These being bedrooms, I need something which is reasonably quiet and efficient with good service backup in the range of 19 and 24k. Knowing my folks, they will not be running these 24 /7. Old generation who likes to save every penny......with very good intentions, of course

@avidyarthy,
My home is located I between Trivandrum and Kollam cities. Humid and temp in summer hovers in between 38 and 40 degrees

hi S_W,

I was following this thread quietly.

I am also in the search for a 1.5 ton split for my 15x13 size bedroom..the room doesn't get any sunlight and there are 4 floors above it.. on other forums I was suggested to look for 1 ton or 1.2 ton splits for my room..

Take a look at hitachi ACE cutout series...
ACE Cutout: Hitachi Home & Life Solutions (India) Ltd.

.9 ton (RAU010HQDP) mrp 26490/-
1.2 ton (RAU014HQDP) mrp 32250/-

you get some discount over MRP.. so price should come down around 24K for .9 ton and 30K for 1.2 ton.. This is 5 star model and I found very good reviews on internet.. Now looking for a shop where I can get the same model and lowest quote..

Comfortable daytime operations in hot-humid conditions would necessitate use of 1 TR models. Latent energy loads far exceed sensible load in humid conditions. Nights could easily have been managed by 0.75 TR.

For your budget, I think LG fits in, with of course a very good after sales service record.

Settle for a 3 bend evaporator design model ..... it allows for maximum de-humidification, hence better cooling characteristics. Make sure that the distance of the condenser (outside unit) is as near to the evaporator (inside unit), with minimum bends on the gas carrying lines during installation. That ensures easy flow of the gas to the evaporator unit and out ..... minimum resistance would also ensure better compressor funtionality. Also necessary to make sure that both units are installed at around the same height +/- 1 ft.

The condensor unit too requires service once a while, so it needs to be placed at a location which is easily accessible. MOST IMPORTANT .... which no one suggests, put the outside unit in a shaded, but well ventilated place. Try to save it from direct rain water and direct sunlight. Why sunlight, bcoz, you are trying to throw out the accumulated room heat to the seemingly cooler outside. The higher the DETLA T (temperature difference) the better would be the compressor efficiency..... and lower power bills.

Tell your folks at home to set the temperature at 24 deg C during night and 22 deg C during daytime for best results. No need to set temps at 18 or 19. That DOES NOT mean faster cooling .........

I would be sending you a bill for this HVAC consultancy .... so, let me have your address ....

 

[avidyarthy]

Agree with Alok.

One on one Hitachi models are better than LG on quality, but do not know about after sales. You can also look at the 0.9 TR model from Hitachi.

interesting, so a 10' by 10' room can easily manage with a 1 ton AC? does this apply for window ACs also or only for splits?

 

[Sujit]

I am using a an Onida 5 star AC. Apparently it uses a Hitachi compressor. Brilliant cooling and no complaints so far over the last two summers.

I used an LG before (2005 - 7) - I was very unhappy with the build quality. Not only did it start rattling, the cooling also progressively got worse. My experience with Samsung, Circa 2005, has not been any different. Given their ad budgets and marketing costs, their machines are clearly built to a budget!

I will recommend taking a look at the Voltas Vertis range (not the gold), Onida, Blue Star etc. My friend has a Videocon .75 ton ac in his west facing 10x12 bedroom in Cochin. I have NEVER seen any ac cool the way that lil thing did in my life!

As far as ACs are concerned - it is best to identify a competent local ac mechanic. No company guy will be able to give you the the service you can get from a local resource - not to mention it will be cheaper as well.

TOTALLY AGREE HERE.
Whichever model you decide on, buy from the local authorised dealer. It is they who you can rely on 100% if anything goes wrong ..... all except the remote controller.

@ psycho ..... yes, a 10 x 10 room can easily be handled by a 0.75 TR AC, any type... split / window. But again, go thru my earlier mails on room parameters that you need to check

 

[deba]

I am using 3 Hitachi 1.5 ton models and they are the best compared to LG......Hitachi is expensive compared to other brands....but its very good......

 

[Sujit]

Also remember - that AC is not just to do with cooling, but also with the often neglected outdoor unit. The quality of materials used to construct the plumbing varies from manufacturer to manufacturer. I have seen O-General, Hitachi, and the old 'National' brand AC's last for over 10-15 years without a single problem - many times not even a topping of gas! That is when true 'value' becomes evident!

I am yet to see a Samsung/LG do that. They are the lowest in the quality chain for me.

 

[smedhavi]

Yes Hitachi is great for bedrooms. The one in my master bedroom has been working effectively without a complaint since the summer of 2002. For the Home Theater I chose a Daikin, as they are the quietest ones. The Daikin quieter models are great but expensive. Hiachi is a bit cheaper, but still much more expensive than the home appliance company products. Unlike the audio world, in the air-conditioning industry you mostly get what you pay for.

thanks,
Sharad

interesting, so a 10' by 10' room can easily manage with a 1 ton AC? does this apply for window ACs also or only for splits?

From what little I know, a 1 ton AC (or 12000BTU or 3.5KW) is called so because the AC compressor is able to provide the equivalent cooling (or rather, heat exchange) of 1 ton (900kg) of ice. Hence, it should not make any difference if the AC is a split or window, or even if you use another method of heat exchange with the same tonnage rating (not a good example, but like an evaporation based desert cooler).

One caveat that I can think of is, as someone else mentioned, split ACs could possibly be made more efficient by keeping the compressor unit in a cooler/shadier place. I guess the same could also be achieved in a window unit if the outside portion of the AC is in shade instead of direct sunlight. In either case, doing this should result in more efficient cooling as the effort required by the compressor to do the heat exchange would be lower due to the lower temperature difference. Regardless of the type of AC, it would make a big difference if the room faces shade or sunlight during the day.

In any case, a 1 ton window unit AC should be sufficient for a 10x10 room. However, this calculation also depends on whether the room directly faces sunlight, number of people occupying the room (heat emanating from their bodies), and other heat sources in the room (electrical appliances). In general, for India, I guess the below can be used:

Compare India - Buying Guides - Airconditioners (Window) - Airconditioners (Window)

Room Size (Sq ft) - Tonnage Capacity
Up to 90 sq ft - 0.8 Ton
Up to 120 sq ft - 1.0 Ton
Up to 180 sq ft - 1.5 Ton
Up to 220 sq ft - 2.0 Ton

hehe, thank you so much for this guidance......there's such a mass of opinion even among AC technicians and dealers that default size for a room is 1.5 TR.....and anything less is for really tiny spaces.

I actually decided against replacing my 9 year old Godrej 1.5 ton window AC (with a reciprocating compressor) in spite of it being full of problems simply because fixing it cost less than a new 1.5.......if i knew i could have managed with a 0.75 or a 1 TR i might have decided differently. I can still dump this in my other room and get a new 0.75 or 1 TR unit to replace this. Even after the repair the blower only functions on full speed and i can't switch it on or off on the unit, I have to do it at the power outlet! it's such a tragically bad machine (and it always has been, i whacked it from my in-laws a couple of years back because they had it lying around spare).

On reading your post I've read more on the net and I can't understand how "conventional wisdom" is so wrong-headed about this stuff!

you also mentioned that Haier is one of the good contract manufacturers, does that mean their Haier branded ACs are also worth a look?

 

[square_wave]

Hi avidyarthy,
You seem to know a lot about ACs.

What are some pertinent features you look for when you shop for one tonne split ACs ?

I got one from your earlier post. Anything more ?

A. 3 bend evaporator.

 

[avidyarthy]

Less on features........simpler the better.

There is a blue-fin or gold-fin coating on the condenser section ... am forgetting the terminology ....thats another ... prevents against environmental corrosion.

Sleep mode

Timer

Backlit remote

Temperature indicator ... either on remote or on evaporator.

Thats what I can think of. No need to pay extra for special filters and blah blah blah ..... all stop working after sometime in Indian conditions.

But, would definitely favour Hitachi 0.9 TR over LG, if price falls within your budget..... better built quality.

I have a US make Freidrich 1.5 TR heat pump (heat-cool) window and 2 nos. Chinese make Electrolux-India 1 TR Splits (heat-cool versions). Delhi requires such features due to climate extremes.
