Also how are Samsung air conditioners? I see some good offers especially if you login to their site as a corporate user.

2T Inverter would be the optimum size.

No idea of Samsung, but I have 5 LG Inverter AC's, and both the cooling and the service is excellent. (I have gone for 4 years exytended service contract, so every thing i taken care of for 5 years - Cleaning, repairs, parts gas etc).

Got it for 37k. Will update the installing cost and experience.

Those ACs give trouble very infrequently, whereas a Whirlpool inverter split Ac I bought in 2020 to replace a very old window unit gives problem almost every year without fail. It was under AMC till this January but now they are refusing to renew it. So I am planning to replace it with a non inverter type Ac as and when a big ticket repair job comes up.

I have heard of quite a few people who went back to non inverter ACs in disgust!

Service experience was good. Other than 850 for stand and 600 off bucks for electrical wire there was nothing else. I could have got the stand for 500 bucks myself but I let it be. I had some drain pipe before hand that was also used.

Yes quite a few people still go for fixed AC’s. This was esp true last couple of years when the PCB repair costs news blew up. However co’s have since countered that by offering 5 year PCB warranties. I think both have their uses. For larger spaces such as drawing rooms where a gathering of 8-10 people can quickly ramp up the temperature fixed speed AC’s work best. However for most bedroom requirements inverters make more sense. Mind you the General 1.1 fixed is still more expense than the 1 ton inverter and has better cooling specs according to the website. IMO inverter technology levelled the playing field somewhat compared to fixed speed compressors where General commanded a premium based on their superior tech and build quality.

You will need 2T. Go for non-inverter, aka, fixed speed AC since the roof is exposed to sun.

Hi folks
Thanks to the changing weather pattern, we finally are in the race for air con for our flat in Bangalore. We have 2 bedrooms which need air con

Bed Room 1 - 220sqft X 14ft (ceiling height)
Bed Room 2 - 300sqft X 14ft (ceiling height)

Our aircon consultant has suggested the following

Voltas Vectra 1 ton , 3 Star rating

However on checking reviews, 3 star seems to cool slower and makes more noise

Request inputs from folks here on what we should go with - Brand and rating

Thanks in advance

A 1 ton is clearly not enough. You need atleast a 1.5 ton unit for Bed Room 1. And a 2 ton unit for bedroom 2. Assuming you live in Bangalore this tonnage should do as the temperature doesn’t go too high all the time. I would recommend Mitsubishi Electric as their 1.5 ton units are also powerful enough for 220 sq ft. Even though I have my doubts regarding their operating range, it shouldn’t be an issue in Bangalore. If budget is an issue I would suggest LG. And yes 5 star machines do have a more efficient compressor which can also reach higher capacities. You can check any models min and max cooling capacities. Daikin, General, Mitsubishi and even Hitachi generally have higher or rated cooling capacities, others generally have lower.

Forget star rating, 1 ton will not even cool the room even if run continuously! I wonder who this aircon consultant is! You really need to check his knowledge and credibility.

You need minimum 2 Ton AC for the rooms - Fixed speed. Inverter will not be efficient in such huge rooms. Since the ceiling is 14feet, fix the indoor unit at 7.5 to 8 feet height from floor. Cool air flows down. You need cool air at ground level and not above. Even with 2 ton the 300sq ft room may not be cooled uniformly. Place the indoor unit in the room near where you usually will spend most of your time, like the bed or the table.

PS - 14 feet ceiling height is very unusually high. Is there any reason for this height?

Thanks for your inputs. I spoke to someone from Daikin who has done over 25 installations in our apt and he suggested the same 1.5 to 2 tonnes

On the height, it is quite interesting. My theory is that the builder wanted to differentiate and was also new to build residential complexes. He has built primarily commercial properties in Mumbai. Infact I have not see such huge bedrooms in apts in Bangalore and hence we had finalized this one

Folks

Are there any alternatives to air conditioners.
I live in Bangalore, and since the past few years temperatures start soaring almost from Jan end and until May.
Nowadays, it is hitting 37+ celsius.

If there is an environment friendly alternative to the refrigerant based ACs, even if not as effective, I'll want to evaluate.

You can try air coolers. Since humidity is on the lower side, it will most likely work as an alternative to AC. Keep atleast one window open in whichever room you run the cooler.

[subraiyr]

On the note of air conditioners and air coolers - this came across in our community. User @Lazy said 37 is the temperature in Bangalore. Seems now that we have a scorcher summer in Bangalore. This was published by Karnataka State Natural Disaster Monitoring Center publishes yesterday's temperature in Karnataka - Bengaluru shows 40 degrees C!

Try air cooler. They can be effective in non coastal areas and are popular in Delhi, Hyderabad etc. But you can achieve only about 2-3 degrees below ambient temperature, no more.

You can try air cooler as others have suggested.
We had these coolers some time back, and my observation was that they start making a lot of noise as they get older.

Do remember that water coolers guzzle loads of water (atleast the old models), and since Bangalore is facing a water crisis, it may not work for all.

............................

Based on my experience you need approximately 1T for every 1000 cubic feet of space. So 220x14=3,080 cubic feet needs at least 2.5T and 300 sqf even more. If there are windows admitting afternoon/evening sun you need even more.

So go for at least 2T Inverter (they will cool faster initially in turbo mode). Use fan at low speed to circulate the cold air for better overall cooling.

Thank you gentlemen.
Am already using a cooler. Something like this, since a few years - https://shop.symphonylimited.com/col...er-air-coolers

But this little guy isn't able to help at all in this year's Bangalore heat.
We have AC in one room, but we really don't want to go that route for all rooms (which seems inevitable, yesterday it crossed 39 C here).

Has anyone tried these products, are they effective?
