Doesn't provide effective cooling even in a small room from the very first day. It has been 3 years and I want to sell it. Power hungry useless product.
From my personal experience of buying an AC I know that I was mostly looking to save the recurrent cost, and I was open to buy anything that will save me money in the long run. Which is why I have made this table below of the maximum Power Consumption (and averaging across various brands and ACs) of Different type of ACs available in the market. There might be a few outliers here and there but the below average is from 1000s of samples. Please read the notes below for my observation based on the below table.1 Ton Window AC :3 Star : 1050 - 1150 Watts5 Star : 1000 - 1100 Watts1 Ton Split AC (The evaporator/indoor unit power consumption is very less, so only compressor power is considered) :3 Star : 1050 - 1150 Watts5 Star : 1000 - 1100 Watts1.5 Ton Window AC :2 Star : More than 1750 Watts3 Star : 1550 - 1700 Watts5 Star : 1450 - 1550 Watts1.5 Ton Split AC (The evaporator/indoor unit power consumption is very less, so only compressor power is considered) :2 Star : More than 1700 Watts3 Star : 1550 - 1650 Watts5 Star : 1400 - 1450 WattsAs a very rough calculation, I will say every extra 200 Watts running for 5 hours (compressor run time, not AC) will cost you an extra Rs.200 per month. For example an AC running at 1400 Watts will have a lower bill of Rs. 200 than an AC running at 1600 Watts if they both run for 5 hours daily. Ofcourse there are other variables in the calculation as well.Observational Notes :1) There is not enough saving between 3 Star & 5 Star rating ACs to save a huge amount of money IMO.2) If Possible going for a lesser tonnage AC, will save a decent amount of money in the monthly bill.3) Ofcourse second step also includes finding the Cooling Wattage of the AC, so just to add Stars awarded are based on the cooling capacity wattage divided by power consumption wattage, which gives EER of a unit.4) There is not much difference between Split and Window AC as far as saving electricity bills is concerned.5) Inverter ACs are a different beast and none of the above points apply to Inverter AC.Just to add a bit about the particular AC, it has good EER based on which stars are awarded. This AC with its very decent cooling capacity and lower wattage compressor will save you quite a big chunk of money monthly depending upon your usage.
Good window AC from Hitachi, one of the top brands. Comes with copper condenser, and gives more cooling than a 1 ton AC. 5 star means energy bills are atleast 10-15% less than 3 star ACs.Go for it.
i purchased this ac from vijay sales new delhi. first year was fine. it started giving problem from second year. gas leaked. nobody could find the puncture. now i have to get it refilled every few months. its not worth the price given. blue star and o general are lot times more better.
I have a 120 sq foot room and it does not cool well. This AC has better specs. It is a bit expensive too compared to other 1 tonners. Bought it after a lot of research and trusting Hitachi quality. May be it will work well for rooms less than 100 sq feet. For 120 sq feet, it takes a lot of time to reach 25 degrees and then the compressor will trip but the room has not reached 25 degrees, I am sure. Now 25 degrees is the best setting of you want to achieve energy efficiency. If you keep it lower from 20-23 it does get better but the compressor won't shut off and honestly it still does not feel like 20 degrees.
