Are Daikin ACs worth the premium?

[Sushubh]

I am considering getting a three star 1.8T unit from Daikin to replace my aging 2T Carrier AC.
I have just checked the prices online. I believe it would cost me in the range of 40-45K depending upon the source.
The 5 star model costs around 8-10K more.
Wanted an idea if it is worth it. Assuming it would last me at least 10 years, I would not mind paying a premium over Hitachi or other brands.

Just out of curiosity, do companies follow this kind of rating "5 Star" in other countries as well?

 

[ghpk]

can someone who has both 3 star and 5 star A.C. post his calculation how much electricity will it realistically save,
I am so very confused with this concept,my electricity bill is sky rocket in summers due to 8 years Old samsung 1.5T Window A.C. in bedroom which works 12-14 hours in 24 hours span.
and my work room 1 Ton, Onida Split Unit, which run less may be around 3-4 hours max per working day.
How much would I save on a 30 day bill of 4 - 5K

 

[Sushubh]

I think someone had posted an online calculator to get a rough idea about the savings. Would be hard to find out.

@ topic - you can also get an inverter AC by brands like Panasonic in that budget, they are supposed to last longer because there is less load on the compressor (no continuous starting on/off). Not sure how it would compare to the Daikin regular AC though.

 

[Sushubh]

Would check out the price range and options available. Thanks.

Basically inverter technology allows the compressor to be run on low frequency as well. In normal ACs when compressor runs, it runs on constant speed no matter what temperature you have set.

 

[Sushubh]

yes yes. there was a pretty long comprehensive thread about the inverter technology...

 

[aviral sangal]

I know this because we use variable frequency drive a.k.a inverter even in our machines

 

[Sushubh]

What sorcery device do you manufacture?

 

[aviral sangal]

No where related to this but its called milling machines

i have had a one star and currently having 3 and 4 star and there is difference.Infact i hardly use the one in my room which is 4 star.
I cannot give exact calculations.but yes i feel the difference.both are 1.5T.the efficiency is about their thermostat actually..nothing rocket science.
When i bought 4 star LG ac,there was a 5 star which could be coupled with fan.So fan can sync with AC and keep the room cool for longer..i didnt like that idea,else i would have gone for it.Those were early days for star rating.
I have seen 15% saving difference in 4 star and 5 star Refrigerator.i can vouch for that one for sure..same volume.infact 5 star one had a bigger freezer,yet it comsumed less power.

 

[aviral sangal]

Err there nothing like efficiency of thermostat. Thermostat is a device which measures temperature and according to that switch on or off the compressor. Efficiency is measured for compressor.

Finally got the quotes...
1.8 3 star 38K1.8 5 star 45K1.8 inverter 47.5K+ costs of stablizer, stand and pipes etc. etc.
Not sure whether to invest 10K extra for a more efficient model. Any comments?

 

[Saurav]

I would not invest 10k for a model which is higher is rating. 10k matters a lot.
