1 Ton Inverter AC

[a.c]

My samsung 1.5 Ton (Non Inverter) AC died. There is a minor leakage somewhere and peoply are suggesting to change the coil of indoor unit.

Looking for a new 1 Ton Split Inverter AC.
Nothing fancy but should be 5 star and a 2021 model. Could not find details about Voltas 2021 models online.
I checked sanyo which was the most reviewed on Amazon. Looks to be good.

Open to suggestions.

feel like 1 Ton would be sufficient.

This is not entirely true. Do you have any of the sides facing the sun? Also, how many members would be present in the living room while using the AC. This could be one factor which could swing in favour of Inv ac since you can reduce the tonnage if less members and increase it if more. Also, it takes care if you have sides facing the sun.
Keep into account external heat sources(Sun, residual heat) and internal heat(members, kitchen next to living room) to determine the tonnage. @Rickysin can share his experience with a lower tonnage ac for his room.

Makes sense about the 8+ hours case, though I will still prefer to go with inverter AC.
No sides facing sun. 3 Floors above my floor. Living room will have max 4 people. Next to kitchen? Yup.
I am now looking for 1.5 Ton or those 1.3 Ton (which go upto 1.5). Will check the local dealers once for pricing.
Mostly looking at Voltas Maha Convertible series and LG Dual Inverter Ac.

Yup, 1.5 ton would make sense. I don't recall anyone giving a convertible ac with 1 ton. I too was looking for this exact feature as my roon suffices with 1.2 ton. Only Japanese brands would give with 1.2 ton, not sure with adjustable tonnage.
So I went for LG 1.5 ton and use it at 0.9 ton after room has been cooled.

My friend has an LG 1.5 ton dual inverter AC. It runs for about 20 hours in a day, unit consumption is 300+

I asked him to give me an exact figure, because 300+ could be 399 as well. Lol

Only buy 1 ton inverter ac if your room does not have any walls with direct sunlight.

do not install 1 ton ac on roof top room.

Also inverter ac benifits starts if it is run continuously for more than 8 hours.
If your usage is like 4-6 hours then better go for non-inverter ac

Quick question. Two rooms in my home have a 3 year old Hitachi 1 ton AC (top of the line at that time). They advertise that the compressor is a variable RPM one.
What it does it as you increase the temperature it reduces RPM thereby reducing the electricity usage.

Doubt is won't every inverter AC have this feature, as that is how the inverter compressors work.
Whats the use of adjustable inverter AC then? Since if I want cooling in other AC I can reduce the temperature and cooling increases thereby increasing electricity cost, but once its cooled I can reduce the set temp, thereby reducing RPM and electricity usage.
Or am I missing something? Other than setting the compressor tonnage in abosolute value does these dual inverter AC offer anything more?

In gen 1 inv ac(Hitachi), the inv won't kick in unless you increase the temps. In gen 2 inv ac, once the desired temp is reached, the compressor automatically reduces speed and maintains temperature without shutting down. You don't need to adjust the rpm, ac does it for you. This leads to more lower savings as the temperature window is very less in new ac unlike old ones where after feeling warm you reduce temp, then increase and the cycle continues.

Other than setting the compressor tonnage in abosolute value does these dual inverter AC offer anything more?

Higher savings. In single inv like in Voltas, Marq, the compressor shuts off if power consumption goes below 400W. In LG, you can go to as low as 170W before it shuts off. So your compressor won't turn on-off regularly unlike in single inv ac.

all dual and triple inverter rotary compresser based ac follows same technology
