Points to remember

Area and Tonnage

• 80-120 Sq.Ft. -> 1 Ton (~3516.85 watt Cooling Capacity)
• 140~160 Sq.Ft. -> 1.5 Ton (~5275 watt "")
• 180~200 Sq.Ft. -> 1.8 Ton (~6447 watt "")
• 240~260 Sq.Ft. -> 2.5 Ton (~8792 watt "")
• 290~310 Sq.Ft. -> 3 Ton (~10550 watt "")

You need to factor other things such as exposure to sun light, number of occupants, windows, heat generating appliances etc. If you have a 110 Sq.Ft. room and say it is in the top most floor and the roof is exposed to scorching sun light then maybe 1 Ton ac will not do justice to you. Go for 1.5 Ton AC.

LG 3 star 1.5ton AC has 4400 watt cooling capacity -> 1.25 Ton . Beware of fake 1.5 Ton ACs.

Amperage of MCBs and Wires

Take an example of Daikin 1.5 Ton FTKT. max rated power is 1650 Watt. So, current required -> 7.5A. Starting current can be 1.5 X 7.5A i.e. 11.25A. So, 20A should suffice. (Without Stabilizer) It also says in the online fact sheet of that AC.

Formula = (max electrical power consumption kW) / (0.9 X 220V)

Different gauges of wires are available. Multiply by 6 to get a ballpark figure.

Image is from -> Finolex's spec for its wires. Check the wire box before buying the wire.

PF = 0.9 (assuming), Max Power = 1680W, Voltage Available 90V, then current needed is 20.74A. (Assuming Stabilizer has 90~220V rating). But most 1.5ton ACs and 4kVA stabilizers use 2.5 sq.mm wire. Stabilizers themselves have output voltage range. And V-Guard VE400 has a current capacity of 12A.

Please @andromeda bhai. please shed some lights into it. I am really confused. The electrician has given a 32A MCB and 2.5sq.mm wires. And please shed some light on the type and capacity of MCB

Use thick wire for earthing.

Proper Planning Before Installation

Outdoor unit should be shielded from direct sunlight. If there is no option, one can have a makeshift shed around it. But ventilation should not be blocked. Indoor Unit should be properly aligned otherwise you might see drainage issues. Indoor Unit's top should have at least 1 or 2 feet gap from the roof. If you put a bed directly under the AC then you might face issues during servicing. (From my own personal experience.)

Use at least 2.5 sq. mm wires for phase. Proper earthing should be done.

Use a stabilizer even if it says your AC has stabilizer free operation.

Efficiency and BEE Star Rating/Manufacturing Year

More Stars -> More Power Savings. But...

Product 1 3 Star one 4th Photo says that it has an ISEER rating 4.00.

Product 2 3 Star one 4th Photos says that it also has an ISEER rating 4.00.

Spot the difference guys 4400 watt cooling capacity vs 5000 watt cooling capacity. But same ISEER rating. Please read those labels carefully.

And the labels are valid from 1st July 2022 to 31st Dec 2024. 🐒

Please don't be fooled, when the sales person says that this model is 2022 model and this model is 2024 model. Bhai no difference. All that matters is cooling capacity and that star label.

Companies are very smart. Daikin's FTKT model has 5.28 kW cooling capacity but it's 2022's model. All of its recently launched 3 star 1.5Ton ACs have 5 kW cooling capacity. Price can be made more competent, quality can be compromised. 🐒

Service Coverage

Please check if your area has good service. Otherwise it is no brainer to invest in a high end model, who has poor reach to you.

Here are my suggestions. I will cover from 1.5Ton(including fake ones) only. But it is easy to select one, once you get to know the criteria.

Take an example of Daikin 1.5 Ton FTKT. max rated power is 1650 Watt. So, current required -> 7.5A. Starting current can be 1.5 X 7.5A i.e. 11.25A. So, 20A should suffice. (Without Stabilizer) It also says in the online fact sheet of that AC.

I'm not sure where did 1.5 come from, this could be from traditional induction motor based, but the recent inverter model one's do not put out this much of starting current. I haven't happened to see more than the rated current during any startup on inverter acs.

PF = 0.9 (assuming), Max Power = 1680W, Voltage Available 90V, then current needed is 20.74A. (Assuming Stabilizer has 90~220V rating). But most 1.5ton ACs and 4kVA stabilizers use 2.5 sq.mm wire. Stabilizers themselves have output voltage range. And V-Guard VE400 has a current capacity of 12A.

First and foremost, if you are considering to live in an area where it drops voltages to 90V, you should think of alternate locations. Lower voltages are expected in summers due to increased load on the grid, but 90 in my opinion is very rare. Even if the stabilizer can operate at 90V despite its nominal working voltage of 220V, I would not let it go through additional stress. The boost conversion (90V to 220V) is not very energy efficient, in other words the PF would not be sitting at 0.9. So I wouldn't stress much on it.

Regarding MCB selections, your electrician's choice seem to be fair. The manufacturers have some details/guide about the selection. It's one's own preference if you know the details.

Example:

Use a stabilizer even if it says your AC has stabilizer free operation.

Sure, if you want to treat the unit like a baby. For that matter the stabilizer is also an equipment which can operate without stabilizer. Essentially most home applicances have a stabilizer in-built, in other words they have a power stage inside which can take a range of voltages and work with them to give a stabilized output to the electronics inside. But hey, I'm not against using them, please do use if it helps with one's peace of mind.

Spot the difference guys 4400 watt cooling capacity vs 5000 watt cooling capacity. But same ISEER rating. Please read those labels carefully.

ISEER is all about ratio of the total annual amount of heat that the equipment can remove to the total annual amount of energy consumed by the equipment in the given duration. While cooling capacity is what the equipment is capable of handling. Just because a car carry 5 passengers, it doesn't mean the fuel efficiency is going to be the same irrespective of load on the car. Higher the cooling capacity, faster is the rate of cooling. It is where you may see those modes like Himalayan Burst, or Thunder Cool or those fancy modes. Sure it consumes additional/high power during that time, but that's what one pays to get what they desire.

The labels has a duration mentioned as makers come up with more and more models competing with their own past models in being energy efficient. The 5-star graded unit 5 years before cannot be the same 5 stars in the recent times. The scale is dynamic. I bring in another model next year, if it can consume a couple of 100s of watts for the same cooling, I get 5 stars, while the existing 5 may get downgraded to 4. It's all relative.

How does open sewage drain affects gas leakage?

Anaerobic bacteria in sewage decompose protein and sulfur & produce H2S (Hydrogen sulfide).H2S reacts with Cu (Copper) & creates Cu2S (Copper sulfide) scales / flakes.Continual flaking leads to coil thinning and eventually causing pinholes & gas leaks.

Where can we get 2.5 ton AC? The max I could find online was 2.0 or 2.2 ton?

Are the higher tonnage ACs (2.5 - 3 ton) are custom made (assembled with components)?

No idea

Thank you so much Bhai. Just one more question. Please tell me regarding the thickness of the wires to be used. Is 2sq.mm good? Is 4sq.mm going to be an overkill?

What's your view on Daikin Hot and Cold ACs? Planning to get a Daikin Hot and Cold 1.5 ton 3 star (I'm based in Delhi). 5 star is not available in the Daikin Hot and Cold variant. Wondering if it would be better to get a regular AC + oil heater or to get this instead?

Great info

best AC

1. Daikin , silent operation will cost more

2.O general .. good in operation and will last long

3.LG .. medium in operation good on pocket

A question on Daikin AC and warranty. I purchased it from Flipkart and got it installed by my own technician. I received a call from the Daikin installation team saying that the warranty won't be applicable if I don't get it installed by them. Any suggestions?

No suggestions. Your warranty is void.

I have recently Bought a LG ac 1.5T and 5 Start, Cooling is very Avg, does not even chill the room when the start temp is 30* . I will for sure not suggest to Buy LG to anyone. Called LG support and Engineer said its working as expected but i'm feeling i bought a Cooler for a price of AC.  So prefer panasonic/Diakin than LG if you need proper cooling

Humans are generally comfortable between 22°C and 27°C, with a relative humidity of 40% to 60%. However, recommendations for summer and winter may vary due to humidity and clothing. For summer, the suggested range is 23–25.5°C (73–78°F), and for winter it's 20–23.5°C (68–74°F). Set to 25 Deg C. you can feel cold

Unfortunately, my experience with air conditioners from all the reputed brands has been disappointing. None have lasted more than four years.

The coils corrode and develop leaks, leading to a refrigerant leak, and thereafter, they cease to function. It seems the quality of products has significantly declined.

Moreover, Companies seem to strategically launch new models annually, perhaps because they anticipate the older ones will fail within a few years, affecting their ratings. Thus, by introducing a new model, they essentially reset the product ratings.

It's disheartening to see the environmental damage caused by these low-quality products. There needs to be accountability for the production of such inefficient appliances.
