How many months?My usage pattern for summer season
1. both inverters if its atleast 3 months a year
2. definitely an inverter
3. is that like an hour each during lunch and dinner? no need for an inverter in that case.

If I were you, then Panasonic would have been my preferred choice. Uses R410A gas, free installation kit, have much lower cooling capacity ceiling under part load over Daikin (no installation kit) and still costs 200 bucks less!!!
Get it boy and don't forget to post some shots of the same.
LG 1.5 Ton Inverter model BS-Q186C8R2 simply put is awesome. Much better than this Panasonic both in terms of cooling capacity and cooling performance. But it has many hidden cost as no installation kit is supplemented with it. Total expenses can rise to something close to INR 52K. And it seems all LG inverter models have this strange ODU fan grill issue where fan touches the fan grill. May be a design or manufacturing issue.
So when are you going to buy this new AC?
The AC's are required immediately and I have been doing my homework for last 20 days as to which AC to go for. Just don't want to end up buying a machine and regret later. I must say this forum has given me much info about AC's. I am thinking of going for this LG model if the installation kit is included else I will finalise the Panasonic one. Will keep you posted. Thanks.
You started the thread asking about cooling 4 rooms. You also say you require all those ACs immediately. Yet you talk about a 1.5 Ton Inverter which is applicable to one of those rooms. What about the other three rooms?
You have not talked a bit about them.![]()
Inverters go do to 10-15% of Max capacity, a 3 ton Outer can go down till 0.3-0.5 .Multi splits are normally used in "luxury" homes where Aircons are never off. They do not work out cheaper, but are definitely better built, and a good chance they are not made in china or thailand and actually made in Japan, so there is a change in quality too.How much are the savings while buying is what I'm asking? Some prices/models will help.
I was not suggesting he buy 4 non inverter ACs, I was saying inverter ACs are used because once the room is cool, your cooling capacity no longer remains at 1.5 or 2T and the compressor can slow down and save electricity. If the multi-split compressor cannot go lower than 2T, and you happen to be using only one AC at that time, you are losing out on potential energy savings which makes it equivalent to a non inverter AC.
IMHO the only saving with multi-splits is space, nothing else.
Considering your room sizes and use, I would go for 1.5 tons each for the 3 rooms, and since you are saying hall may be split, 2 x 1 ton inverter if usage is high(or a 2 ton multiplit) .. ORMy usage pattern for summer season will be as below:
1. 2 AC will be used daily from 8 pm to 9 am.
2. 1 AC will be approximately used the whole day and night- 24 hours.
3. The hall AC will be used as per the need, if everybody is sitting in the hall like during the lunch and dinner time.
Not sure about 10-15%, its usually more like 25-30% since it gets more difficult to run bigger compressors at lower speeds. As an example, the Sharp Multi-split which is a 2 ton outer goes down to 0.65.Inverters go do to 10-15% of Max capacity, a 3 ton Outer can go down till 0.3-0.5 .Multi splits are normally used in "luxury" homes where Aircons are never off.

I studied Multi splits about 5-6 years back, Toshiba and OGeneral were the only ones in the market. Completely built units imported from Japan, and they did go down to ~15%, dunno what the other brands do these days. Multisplits are definitely more expensive then equivalent number of single splits. But one has to consider the total cost of Installation, wiring etc and they just about break even, there is no real capital cost saving. The saving is in build quality, they are built to last longer and run more. The downside, if it goes you are dead, Full house without air conditioning, which is another reason of lower failure rate. Primarily sold / recommended for 24 x 7 Ac homes.Not sure about 10-15%, its usually more like 25-30% since it gets more difficult to run bigger compressors at lower speeds.

You might have a point about the better build, since AFAIK they tend to be more expensive. I was just a bit surprised that it was being suggested as cost effective.
Multi-splits will be never be popular in Indian residence due to their rare needs. The distributors import these units in small numbers so the price remains very high. Also very few companies have inverter multi splits so there is almost no competition which lends to sky high price. They are never VFM products.
Let us consider the 2.5 Ton, Sharp AU-X3M24MV multi split ODU unit having 3 IDU units. Two of them are 0.8 Ton and the other a 1 Ton. Total cost is a whooping INR 95K. We do not even know whether installation kits are provided (most probably not) and the installation charge will be very high since R410A copper pipes are quite costly.
This Sharp multi split unit have quite a high rated cooling performance of 3.61 EER and can come down to a cooling capacity of 2.1 kW which is 24% of the its max of 8.9 kW. On the other hand 1.1 Ton Inverters from the same manufacturer costs at around 31K and comes with free installation kit. You can have 3.3 Ton cooling capacity from three of them while total cost is less than this 2.5 Ton multi split. All units of Sharp comes imported from Thailand.
Till now we have talked about money aspect, let us have a look energy savings point of view. Each of these individual 1.1 Ton units have an even higher rated cooling performance of 3.63 EER and can come down to a cooling capacity of 0.8 kW which is 19% of the its max of 4.2 kW. Add with all three of them running simultaneously you get a 0.8 X 3 = 2.4 kW minimum and a 4.2 X 3 = 12.6 kW maximum cooling capacity.
In the end the multi splits neither have any performance advantage or cost advantage or build quality advantage or are more energy efficient. On the contrary their spare parts are very hard to come by due to their rarity and costs a bomb to replace.
Until there is a law forcing Indian citizens to use one ODU per residence, I don’t believe they will ever become popular.
Today may not be the day, but its day is coming too.
I was talking about the present AND the future. Present the facts with accurate information, not twisted to suit our conclusions. You make it sound like money is the only consideration when buying an AC, and as such multi splits have no right to even be in existence.I was talking about PRESENT and not the FUTURE.![]()

They have their advantages and disadvantages.
