I have a 3 phase connection too. 2 phases have all of the power appliances on them evenly distributed to spread out the load. The third phase runs all the lighter fixtures and is also connected to an inverter. In case of powercuts at night while the a/cs go off the fans continue to turn and one can dream on.

Yes, the ODU is 6 inches from the wall & the verandah is pretty breezy. |
I was looking for a unit there as in 60 bar, 60 psi, 60 something.
On the ODU side I was asking whether there is an obstruction in front of the fan, in the direction of the throw. Also 6" of space behind the fan is hardly any space to allow the fun to suck in the required amount of air to pass over the heat exchanger. Even in the tightest of installations the ODUs will have a 10" to 12" space on the rear side to allow for proper air flow. I suspect your compressor is being forced to work with hot gas instead of one that has been sufficiently cooled. I have explained this scenario in one of my earlier posts.
I would recommend that you get the install of the ODU checked out and reconfirm this 6" business. If it is indeed the case moving the ODU further out by another 6" or the maximum possible will help. Of course the requirement of having a clear area on the other side for a proper air throw stands.

DO remember to have the gas topped up once the IDU is changed and actually that would be a great time for them to move the ODU too provided the bit about that 6" gap is correct.

In one room ac use is pretty less .Individually i would require two 1.5 tonnes units in each room.Whereas as per my research a single 1.5tonne multisplit will also take care of both.But i am confused about reliability of multisplits as they have valve actuated mechanism for control of refrigerant flow in each indoor unit .
Also not major difference in cost between two options. |
A stand alone unit also has the 'valve actuated mechanism'. So that should be the least of your concerns.
If you are getting a multisplit which is actually running a single compressor then go ahead and get it. This is a very robust design which requires components built to better standards than usual, thereby increasing the costs involved. For exactly that reason the units masquerading as multi splits in our market generally have two compressors + H.Ex. sitting under a single ODU cover.

He suggested 3 alternatives:
a) He shall return the AC without any charges.
b) He has a stock of 3-4 year old hitachi 1.5 tons AC which he claims he buys in bulk from the companies like infosys which change their ACs every 3-4 years. He is quoting a price of Rs.6500 for the same.
c) He is also a dealer of Blue Star which he has quoted for Rs 16500 for 1.5 tons in exchange . |

The best bet in that budget would be a Whirlpool machine, stay away from Bluestar. Ask the repair guy to give you the contact details for the raddi wala who specializes in old aircons. Contact him and strike a deal to sell your old machine. this guy will give you the best deal. Or use the old machine in the exchange scheme. Air care in Vashi Plaza had something going on as did Arcee in Shanti Center both in sector 17. Negotiate without exchange being mentioned and then throw this in after all else including installation has been negotiated. Infact contact the raddi wala after your old machine's price has been determined for exchange as then you can get a better price for your junk.

What do you suggest guys? The sales person is known to me as we buy most products from there itself and he suggested whirlpool but then i dont trust sales people!
Also how is the daikin service experience? |
Hmm.. if one cannot trust a known person, it is best left to imagination what value can be derived from posts of people unknown.
Ghar ki Murgi dal baraber....
Anyhow..
All window machines make a noise which is basically due to the high cfm of their fans and poorly finished vent components that shudder due to the high velocity of the air passing over across them. The fact that the air itself has to do a 90 degree turn to come out of the vents does not help as one gets to hear the noise due to the hammering phenomenon.
The IDUs of the splits have an air path that is straight out. Further the IDU fan runs at much slower speeds than their window counterparts thereby even the air cutting noise is minimal.
Whirlpool splits are as good if not better than the Hitachi's of the world, that too with excellent service backup and less money. Daikin has a fantastic service backup provided a few pre conditions are met with. To know more abut these preconditions you would do well to go through the last dozen or so pages, wherein this has been discussed to death.
