Hi,
I am looking to buy an split air conditioner for a 10' x 12'' x 10' room, which has a large south-facing window. Window is blocked by adjacent buildings and trees, so not much of direct sunlight at all. AC would be used for about 8 to 10 hrs each day for 5 t0 6 months in a year. The rest of the months, may be just an hour or so each day, if at all.

1. Am I right in assuming that a 1.5 ton unit should be adequate for the room?
2. Do I need to invest more and get an inverter model? Or is a non-inverter model enough for my needs?
3. What star rating AC should I be looking at?
4. Any suggestions regarding models and brands?

My budget is gonna be 40K, including installation and such.
 
1. That's 120 sq ft right? Is this a room with the terrace directly above, or does it have another room on top? 1.5 ton should be ok, maybe a little overboard but not an issue if you get an inverter.
2. 8 to 10 hours for half a year is fairly significant enough to see a saving with an Inverter AC. IINM 5 star ACs from the big brands are pretty close to Inverter prices as well.

4. I'd suggest working backwards and checking which brands offer good after sales and service in your locality.

@Crazy_Eddy Yeah. There is a terrace directly above.
I am not really aware of the ASS of some brands in Pondicherry (which is where the AC will be bought). Most people I know are using LG or Samsung ACs. Somehow, going through the various posts and threads in this forum, I believe there are better brands than these. Hence the question.
BTW, I think it is really difficult to fit a 5-star or inverter ac within my budget, isn't it? :(
 
1.5 ton will surely be adequate for the room (considering the terrace above). You may consider "O General" or Hitachi. However you will have to extend your budget a little higher. But do check the after sale service in your local area.

If you have a tight budget, the Panasonic YS18PKY 1.5T inverter is the cheapest inverter AC I know of and very close to 40k. Specs are strictly okayish.
AFAIK Sharp Inverter ACs still top the specs race, but they're closer to 50k and have very limited after sales centres supporting them.
LG also has Inverters with good specs, and I think there is a variant with specs on par with the Sharp, but they're also a bit expensive around the 50k mark.
Samsung Inverters look good on paper, but not aware of any users having tried them and not aware of prices.
 
I'm in the same boat as yours. Looking for 1.5 Ton Inverter AC to upgrade our 10 year old Carrier Split AC.
Confused between Samsung and Bluestar.
'I feel' feature in Bluestar sounds good theoretically, as it senses temperature from Remote.
Samsung is costlier too, Dealer quoted 54K+ Installation charges, where as Bluestar is coming for around 50K+Installation.
 
Damn.. 50K+ is really overstretching my budget.. I will try and look out for a bargain on Sharp inverter ACs when I visit my hometown later this month. Snapdeal has them at around 45K, but Sharp explicitly states in its website that products from SD have no warranty.
 
Just now got update from home that Dad went ahead with Bluestar Inverter AC. It is being installed as we speak.
Will update his feedback after a couple of days.
Final price was 50K with installation.
 
Don't buy Samsung in ACs, yes they look pretty good on paper. Bought a window AC of Samsung, never to buy again.
LG is better in this regard, but fair inferior to dedicated AC brands. But it's inverter ACs are fairly decent.

I'd go with Daikin, Ogeneral, Bluestar, Carrier, Lloyd, and voltas in that order. Bluestar is a good choice, update us with the product review and model number.
 
I was keen on getting the Hitachi Kashikoi series, but the idea was dropped due to lack of local hitachi service.
You can have a look at them as well.

The indoor unit is smaller than previous one, you can observe the unpainted part to compare size of old carrier 1.5 ton unit.
The outdoor unit was bigger than old one.

The part load efficiency (2.73/2.42) doesn't look good for the 1/1.5T models. Its much better on the 2T model.

1 ton is more than adequate for the small room with no direct sunlight.

Since he has a terrace directly on top it might be pushing it - insulation is generally poor. If he's considering an inverter AC, then oversizing is always recommended.
 
@logistopath : is this your own house? One layer of ceramic tiles on the terrace dramatically improve the insulation. Very economical too. That will allow you to buy the AC for your 6 months need.
 
@Crazy_Eddy : initially did not notice the terrace aspect.

@logistopath & @Criminal : I am talking about simplest cheapest ceramic tiles, may cost max 10-12 Rs/s.ft. If you can push it, couple this with a false ceiling (thermocol : 20-25 Rs/sft or, POP ~40 Rs/s.ft).

After that (even 1 of the 2 steps) you can go for a smaller 1T AC.

These two steps may even eliminate your need for an AC :)[DOUBLEPOST=1426694139][/DOUBLEPOST]@logistopath : one safety heads-up on false ceilings.
Many times people don't realize that the ceiling height will reduce when a false ceiling is installed. One reason maybe is that the contractor normally leaves a foot as margin. This brings the ceiling fan dangerously low in some cases.
Check out your case.
Note that even a 6" false ceiling will help.
