If you want to buy AC, go buy it, I will suggest which is best for you but keep the following in mind
There is no electricity in Delhi, AC leke kya karega?? My neighbour has bought a fantastic split AC 1.5T and he is unable to use it.
It is only a show piece
If you still want to buy AC, I suggest you the following
1) What type of AC you need?? Split or window
Split is costlier, more electricity is needed, but no sound, quick cooling, no place problem.
Window looks awful, more sound, constant cleaning
2) your room size, if its small buy 0.5 T, or 1 T. If its big buy 1.5 T
3) Do you want your AC to work for more years?? then buy foreign brand
4) Dont buy Indian brand and remember Voltas India ka AC, Korea ka nahin A TATA PRODUCT. after you buy it they will tell show you tata
theeir stupid ethocentrism campaign..yuck
5) why is letter B always cool?? because it is between AC
6) AC is harmful to the environment and it creates black hoele in ozone layer, it is not good for us.
7) If you still wanna buy no problem, you wont be alive till the hoele in ozone becomes big, who the hell anyway cares about future generations..rite??
8) Price of AC is also important factor. what is your budget?
9) Dont but second hand AC, it is worse then first hand
10) Dont forgot to get information about the gurantee and warranty.
11) Ensure they give you after sale service because AC falters too often
12) there should be constant even voltage supply at your home or else when AC is on, fridge is off, if motor is on AC is off
i am sure you have found my advice very useful, buy a good AC and write the feedback.
If you still have any questions ask me I am always at your service
