The reviews that I see on the net are mostly positive, does anyone here have any experience with this model ?

Thanks for the feedback.. (Wonder why there's no "Thanks" link in threads in this section. Would have been quite handy)

I almost made the purchase yesterday when the Panasonic salesperson there mentioned that they're likely to get some stocks of a newer model in another 3-4 days. So decided to wait till I look at them as well.

Thanks M5 fan. I saw the Sharp model referred by Inquisitive. It is by no ways economic [over the Daikin]. However, my decision will be between Sharp and Daikin, with my own economic reasons coming into play.

Do both Sharp and Daikin have good service backup [if one needs it]? Panasonic better than Daikin [from a technology and customer service perspective? The previous pages I browsed through didn't seem to say so (also maybe I didn't read well enough)].

I have immediate plans for buying a 1.5 ton split AC for my parent's room.

We have 4 other ACs installed - one each of LG, Whirlpool, Voltas and Hitachi - all performing satisfactorily.

Went to Khosla electronics last night and they are suggesting Electrolux SQ52 (asking around 25K) or Panasonic UC18PKY (asking around 30K).

Any user experience on the same models? Any other suggested 1.5 ton split models?
Thanks.

@blackasta; Make sure it is R410a and not R22. Of the two I will take the Panasonic, purely on the brand standing.

If you go through the datasheets, both sharp and panasonic inverter acs have a lower min power consumption value which comes into play when the outside temperature is not very hot.

Also both are cheaper than daikin and come with assembly kits.

The service guys of sharp and panasonic are more knowledgable and professional as compared to the daikin guys in my area. The daikin guys are complete pappus in my area.

I bought the sharp XP13LV for 31000 in delhi a couple days if days back. It is a 1.1 ton inverter ac. It also has an ioniser which the daikin doesn't afaik. Also a similar R410 product from daikin costs around 45000. And it doesn't even include the assembly kit.

Hence both panasonic and sharp are economical as compared to daikin. See buying a daikin is like buying a merc, it has brand value and quality. But is it that everyone who is looking for a car in that segment is gonna buy a merc. Well my comments make sense only once one can look past the brand value.

Hi SGIITK,

In terms of performance in high outdoor temperature conditions, how do these two compare. In India, being able to operate well at 45 Degree + temperature is vital, at least in North India. In this scenario, which refrigerant is better - are there two the best or are there any other options used currently in India.
Would appreciate if you could share some inputs on this.

Thanks!

I've had a bad experience with Whirlpool. I had purchased a Whirlpool Chrome 1.5T AC from Chroma Retail in March 2012 in Mumbai. In Jan 2013, less than one year of purchase, suddenly the AC does not switch on. When I logged a complaint, the technician came within 24 hours (the Good part!) However, after some testing he declares that the PCB has conked off and needs to be replaced under warranty. Then comes the month long wait and ordeal. Numerous phone calls and emails from my side and multitude of false promises from their side followed (wrong part was delivered, part not in stock, will get done in 3 days etc). they finally fixed it in Feb end, after nearly a 1.5 months wait.

Another lack of cooling issue with my Whirlpool 410L fridge in Bangalore within 2 years of ownership. Whirlpool has not yet fixed it despite good amount of followups. Hoping they will do it today.

Have made a promise to never touch Whirlpool products with a barge pole. Will go for LG, even if it is priced higher. I've heard that their service is very good!!

Anyone else had a bitter experience with WP or am I the special one?

Please correct me if I am wrong. The dehumidification results in lower relative humidity in air and as a result one perceives lesser temperature. Now if an AC unit cooling the air automatically dehumidifies where will the condensed water go? Obviously it will condensate on the lowest temperature spot on the room that is on the cooling coils in the blower. The colder and dehumidified air is then released back into the room giving you the cooling effect. That is the relative humidity of the room is being controlled. Now what happens if you are instead using a dew point (temperature at which water vapor condenses into liquid form) control? Using a high dew point (consider any psychrometric chart, for the parameters that contribute) will result in removal of moisture at a higher temperature basically increasing your comfort level even at that point. Dehumidification also results in lowering the enthalpy (heat content) of the system that will also help in changes in temperature faster and efficient. High-efficiency air conditioners of these days use this trick to achieve better comfort level sooner.

With all due respect, I feel awkward to receive such an affront from a senior member. Speaking for myself, my difference of opinion would have been more polite.
Firstly I would very much doubt what percentage of AC users in India actually receive that sort of attention during install. Well if a home AC installation requires that amount of attention then it must be a very serious business and thank goodness that mine was nowhere near.
Secondly for outsourced service for different AC companies, I think the technicians who run the last mile like in any business make the difference to the customers. Had the quoted opinions were true for AC servicing all the service related grumblings in our forum should be summarily rejected by the moderators IMHO.

Is there any company in Bangalore which offers consultancy on which AC to be installed after inspecting the office space?
There is an office room in my Wife's office which has poor cross ventilation and hence becomes very hot and stuffy.
This is an urgent need. Would really appreciate any advice/help on this.

Can anyone tell me how to understand whether my A.C is a R410.

I got my Samsung delivered yesterday. It's yet to be installed. Chose it over Daikin because I was not sure about the service network in Kolkata. Same reason for not choosing Sharp.
P.S. mine is a February 2013 manufactured model.

The gas type is mentioned in a label on the ourdoor unit. Or you can find it in the specifications table of the user manual of the Ac.

Yes, Daikin and Blue star does it. I am not sure about the others.

Could you explain how such control may be obtained? I mean the 'dew point control' that you are talking about.
The dew point is something that you have no control over. It is dependent upon the temperature of the air and the barometric pressure prevailing at that time. There is no way to change the dew point to a value that one likes or fancies!

Well, we have two Whirlpool fridges and an AC. Never had trouble with AC and the smaller fridge runs like a dream, but the compressor of the large fridge conked off within a year of usage. We had to make several calls and write emails to Reliance and Whirlpool both of whom were trying to wash their hands off the warranty claim and finally got it fixed about 7-10 days later. Thankfully, the little fridge helped during the downtime. But, overall, I'm pretty satisfied with the quality of Whirlpool as compared to say the Voltas AC we bought that has always troubled us.

Excellent point!! Lets work on the psychrometric curve a little bit. Consider a situation when the relative humidity of the room is at 40% and the dry bulb temp at 25 deg C. The dew point in such a room would be somewhere near 11 deg C. Now the way you can raise the dew point is by increasing the pressure within the room because other two options that is either increasing temperature or humidity will beat the purpose. Now Sharp is saying that they could increase the dew point by increasing the airflow. Please refer to the Sharp website for their detailed catalog. I request distinguished BHP-ians to please throw light on this.
