Air conditioner 1.5T

Hi,

I'm looking for a power-efficient AC for my 15x10 room. My location is Delhi and as you may know, in Summer temp will go around 42-45 degree. There is another story about the monsoon as well.
Any suggestions (from below) or any other option?



 
You can get 3 star models also for cheaper. Haven't used these. But have a carrier midea split ac 1.5ton 3 star working since 4+ yrs, a 1 ton window non inverter from godrej working without issue for 4+ yrs and recently bought a inverter split 1.5 ton 3 star godrej.
My old split inverter ac is very good. Consumes 350-450 watts and takes like 2-3 units for 6-7 hrs.
for non inverter ac i got to know one thing from my experience. If i run 1.5ton ac at 27 degrees for 6-7 hrs it would take 4-5.5 units. Reduce temperature and consumption of units increase by 2-3 units.

I recently bought a Panasonic 1 ton 5 star(they havea 1.5 for the same) from amazon for my room (13 x 11) and that uses around 3-4 kWH at 22° for 7-9 hrs everyday...
Im from Hyderabad and temps have gone around 40-43 in the last few weeks...

3-4 kWH is very good for 7-9 hours. I've bought Daikin 3star at 37k. Installation charges came around 7k includeing 3 meter additional copper pipe, odu stand, 4core wire etc. Cooling is really great
I've installed ODU on roof without shade so electricity might be a little bit higher. I will update after some time.

Daikin is looter when it comes to installation. My cousin got installed same model and they charged 3k, and only expense from their side was ODU stand.

nitin again it varies from place to place
I got my daikin ac installed and they charged me 800 for the stand and when I called them again for another installation i got the stand from amazon and they happily installed that.

The two things you should check one is the cooling capacity should be above 5000W and other is the power consumption from where you can get idea about the running cost
Compare the running cost and the purchase price you should decide the star rating value for money model.
1.5 ton gives you the cooling capacity from 4600W to 5300W which is a large variation

Atleast on Amazon installation charges was/is showing 1500/- rs +gst.
 
It really depends....the godrej guys here took installation charges which comes out to be 1415 with gst but, if you have your own stand then they charge extra to fit that stand otherwise it's 800 for stand with installation. Same for extra copper pipe. Nothing such sort of was with my carrier midea ac installation. Guess next time would call urban clap guys or a local guy.

Please be aware that first-time installation should by a company representative otherwise warranty will void.

Yeah I got a question. I just bought a 1.5ton LG , but it has a cooling capacity of 4400w. So has the definition of 1.5 changed? I thought same tonnage should provide same cooling capacity. Because an average buyer like me never noticed it until now. Why have Companies started to do this? Or new AC's are more efficient, Hence they provide better cooling at lower wattage? What's the deal?

As per the latest BEE Star ratings, an AC needs an ISEER above 5.0 to be labelled as a '5 star' AC. ISEER of 4.5 to 5.0 is 4 star.
An inverter compressor's efficiency improves at lower cooling capacities. So they are de-rating the compressor to boost ISEER to 5+.
Yes, they are cheating the system. Older LG units rated for the usual ~5KW cooling capacity had a lower ~4.7 ISEER.

Edit: Which model is it? The LG 2024 models seem to be rated for 5KW again.

Yeah, makes sense. I got LG 1.5 ton 3 star.

Also, the Older LG 1.5 ton(s) dual inverter i bought 3yrs ago have 5000w cooling. So it never came to my mind to check for wattage, i just thought "tonnage is tonnage". Anyway, it appears to be new trend in LG.

Your AC is definitely providing less cooling than a true 1.5 ton. It is true that the newer AC has more cooling per watt of power but the cooling watt is different unit. Your AC should be 5000watt cooling. The companies does these kind of false claims all the time

Star ratings are for the power consumption and the cooling capacity has no significance in star ratings. If your AC gives 5000watt cooling and consuming around 800 unit of electricity for the test of 1600 hours it will be around 5 star. If your AC consumption is 600 unit of electricity and cooling is around 4000watt it will still be 5 star. So star rating is proportionate to the electricity consumed to the cooling capacity. If the less cooling the power consumption will be less.
 
Sorry to hijack the thread but I have a Hitachi Kashikoi 5100X 1.2 ton 5 star inverter AC bought in late 2019.
Every year it has some issue or the other and now the outdoor unit PCB is kaput.

Every support guy always bemoaned the fact that inverter ACs are not reliable and either the indoor PCB(8k) or outdoor PCB(15k) will go bad.

Now the AC is not cooling since the cyclone in Kolkata since Monday and the support guy who came this time said outdoor PCB is gone.
He suggested two models to me for at least 10-12 years of hassle free operation-

Hitachi Ryoku( This model is not made available to consumer showrooms and can be only purchased from the support center)
Carrier CamiPro( This can be bought in showrooms but didn't see this available anywhere online).

He quoted a new Ryoku model will cost around 32k or so which is lesser than what I had paid for the Kashikoi.

What do you guys think?

How is a Hitachi guy recommending a Carrier model? This is a side hustle of his and not something Hitachi is offering. Is your PCB not covered by warranty since it's a 2019 purchase?

No my Hitachi AC out of warranty.

He is not selling the Carrier model and suggested to get it from electronics stores.
The Hitachi Ryoku model they can sell from their Hitachi-affiliated service center itself directly to customer with official warranty and all and they can install it by next day.

TBH I was surprised with his candor as well as every other support guy I had asked this question side-stepped making a suggestion.
