Electricity Saving Tips For Homes And Offices

Ideal Air Conditioner temperature for electricity savings

By on January 18, 2017

Buying an air conditioner once considered a sign of luxury, is now becoming quite common in India. Many urban homes are equipped with air conditioners in one or more rooms. But everyone who owns an air conditioner knows that it comes at the cost of increasing electricity bills. Although cooling does take a lot of electricity but taking effective steps can surely get it down. One of the main things that can help is maintaining the right temperature for the air conditioners.

How does an air conditioner work?

For most people, air conditioner just throws cool air at the temperature one sets it at. But does it really work that way? In fact air conditioner during cooling process, takes the indoor air, cools it  by passing it through evaporator coil and throws it back in the room. It is quite opposite to how our good old air coolers used to work. Air coolers used to take outside air, cool it with water and throw it in. But air conditioners just work on internal air.

How does the thermostat work?

If you set the thermostat at 18oC (64.5oF), does it mean that the air conditioner will cool the room faster than if set at 25o(77oF)? No. The thermostat just checks the temperature of the air inside the room and stops the compressor when the temperature reaches the desired level. This means that the compressor will work longer if the temperature is set to a lower level, i.e it will work more and use more electricity if temperature is set to 18oC (64.5oF) than if it is set to 25oC (77oF). This is because it will take less time for air to reach to 25oC (77oF) than 18oC (64.5oF) as the compressor is working with the same power or wattage.

What happens when the compressor stops?

The air conditioner just blows the fan when the compressor stops and thermostat reaches the desired temperature level. At this stage the electricity consumption is only for the fan which is running and not for the compressor. The compressor will start again when the thermostat detects that the temperature has increased again from the levels that are set. Compressor is the most electricity consuming component of an air conditioner.

What factors impacts electricity consumption of Air Conditioner?

There are 4 factors that influence the electricity load:

1) Indoor air temperature

2) Outdoor temperature

3) Thermal insulation of the room

4) Temperature setting of the air conditioner.

If the difference between temperature desired and indoor/outdoor temperature is huge, then the air conditioner will need lot more electricity to cool the indoor air to desired temperature as the compressor will run for longer duration. If the temperature is set at 18oC (64.5oF) and the outdoor temperature is 38oC (100oF) then the electricity required will be lot more than when thermostat temperature is 24oC (75oF) and outdoor temperature is 38oC (100oF). As per study by ACEEE (American Council of Energy Efficiency Economy), increase of each oC can save 3-5% of units consumed. This can considerably bring down the units consumed per month in the electricity bill.

What is the ideal temperature that should be set on thermostat?

Having said that, increase in temperature does not reduce the comfort level. In fact as per ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers), the ideal temperature for thermal comfort is between 23.5oC (74.3oF) and 25.5oC (78oF) in summers (depends on several factors as listed on wikipedia). Thus setting the temperature to 24oC (75.2oF) saves on electricity bill and provides good comfort. Using ceiling fans along with air conditioners can additionally help in increasing the thermostat temperature.Air Conditioner Temperature Infographic

Does “Quick Cool” option in Air Conditioners help?

Setting an air conditioner to quick cool sets it’s temperature to 18 or 16 oC (64.4oF or 60.8oF. This means that the compressor stops only when indoor temperature reaches this level. But while coming down from 35 or 40 oC (95oF or 104oF) it would have surely crossed 24oC (75.2oF) which is a comfortable temperature. So using “Quick Cool” option does not help because more electricity is used to get the temperature down to 18oC (64.5oF) whereas compressor would have stopped in between if the temperature was set to 24oC (75.2oF) thereby consuming less electricity.

How do old air conditioners without thermostat work? 

Old air conditioners without thermostat have high, medium and low cool options. As we learnt earlier that compressors of air conditioners work in binary mode (either they are on or off), an air conditioner without thermostat does not control air temperature. The high, medium and low options just changes the air conditioner fan speed. High means that air conditioner will throw more air and low means that the fan speed will be slow.

Here is a short video for tips to reduce power consumption of air conditioner in India

Hey..i have purchased gorej split ac 1.5ton 3star and i have set the temp at 22℃ in cool mode and ac cools the room when it is switch on but after half an hour it feels that it does not cools the room..why?
And also i want to ask whether we have to select the ac fan at medium or high level even at cool mode? And ceiling fan can help to maintain cool air in the room..

Hi Abhishek,

recenty I bought a Voltas 1.5ton 3 star ac Model 183 LY-M .
Now the problem is
1. when I run it on Auto mode keeping the Temp at 30 degrees, compressor do not start . it starts when i change the temperature to 29 or 28 degrees. Is it normal?
2. When i switch to cool mode, the compressor never auto cuts after maintaining the temperature, be it on 25 degrees or be it on 30 degrees (at 30 degrees, it is supposed to work)
3. when I switch to dry mode, there is a cycle of auto cuts, Means the Compressor runs for exact 10 minutes, and then it auto cuts for exact 5 minutes

My major point of concern are point 1 and 2.

Can u please guide n help.
Thanks

Hi Gaurav,

Here is my response:

1) I guess when you set it at 30 there is not much heat to remove from the room (because outside also the temperature would not be much high considering it is monsoon season). When you change it to 29-28 then there is some heat to remove and thus the compressor starts.

2) Ideally even at cool mode it should not work at 30 degrees if it does not start at 30 degrees in auto mode. The auto mode just adjusts fan speed to maintain the comfort level. But the operation of the compressor at similar temperature setting should almost be similar. So it should not start the compressor at 30. Also if it does not start at 30, then it should cut off at 25. Because if the outside temperature is not much the heat load should not be much at 25 as well. So it should cut off. Usually ACs do not cut off when they are undersized or when heat load is high and the tonnage of the AC is less.

3) In dry mode it is supposed to work on removing humidity. The priority is to remove humidity and then on cooling.

It sounds a bit strange and I think you should get it check by an engineer from Voltas.

I have a inverter ac of BlueStar 1ton ISEER 3.99... first few days it used to reach the set temperature of upto 23 degree very soon. Now even if set temp is 24 there's always a difference of 2 to 3 degree. Is it normal ? What made me worried is when I set the temp at 22 degree for about 2 hours it consumed 5 units of electricity and reached 25 degree only. Outside temperatures here in Assam is just about 33 degrees at night... my room gets direct sunlight from top n side so I neeeded d ac... plz reply !

Hi Asif,

I hope you have done the right tonnage calculation using the calculator on this website: https://www.bijlibachao.com/top-ten-appliances/best-air-conditioner-ac-window-split-hitachi-lg-carrier-samsung-electricity-consumption-tonnage-in-india.html

Also 5 units for 2 hours is absolutely not right for any inverter AC. You should put a complaint with Bluestar for the same.

Hi Abhishek,
Firstly I would like to thank you for your efforts to make us understand the norms of AC in layman terms.This info are precise and helps to get a better insight. Secondly, I would like to have your opinion on budget AC
I am looking for a budget 1.5 ton AC for moderate usage under 30K with copper condenser. I have my flat on 17th flr with area around 150-180 ft. I have zero down to below ACs. Please assist me and suggest whether inverter AC is necessary for moderate usage
Voltas 1.4 Ton 3 Star Split AC
Carrier 1.5 Ton 3 Star Split AC

Hi Abhishek,
The location is Mumbai and the area of the living room is around 150-180sqft
I have zeroed dwn to godrej gsc 18 FFZM 3 Rwpm
As my usage is minimal to 3-4hrs and might increase during summer season
Pls suggest

Abhishek Jain (Mod)

You can certainly go for the Godrej model that you have selected. Usage is not high so that model should work fine.

Abhishek Jain (Mod)

Hi Roshan,

I hope you have done the right tonnage calculation using the calculator on this site. Because if your room is on top floor then you may need more cooling. Tonnage will also depend on your city. So please use the calculator and do the right calculation.

Also choice of star rating etc will also depend on your usage. If your usage is high then it will be better to go for inverter tech AC and you may get 1.5 ton inverter tech AC from Hyundai or Sansui in your budget. But if your usage is low then you may go for BEE 3 star rated normal split AC as well.

You have not mentioned the model that you are looking at and so it is very difficult to comment. Difficult to say anything just with the brand name. Because Voltas has multiple models with BEE 3 star rating. But in general I would say Carrier would be a better brand.

Sir where the two copper pipe is connected with the ourdoor unit, dropleta of water are dropping.
Is it normal?

11
Abhishek Jain (Mod)

It means insulation is bad. It is not normal. It is bad installation.

12

I have bluestar 5cnhw18dafu i operate it on 28degree on that we got comfort but not so cold
Is it equal power consumption if i operate it on 24 instead of 28 in this model?
AND...
Which one best 28 degree with ceiling fan OR 25 degree without fan?

13
Abhishek Jain (Mod)

Power consumption will be more if you operate it at 24. 28 with ceiling fan will consume less electricity.

Dear Sir,

I'm writing to seek your advice in purchasing an AC split. Room size 12x12x11 first floor direct sun whole day from roof and two walls. Previously i had 5W18LC bluestar installed there which is 5 star 1.5 ton. but the AC never reached to its set value of 20deg it continued displaying 26 deg even running for 3-4 hours. bluestar team visited and said AC is working fine.The room is not getting cooled as per set temp. then i installed it in other room and looking to buy a split for this room. please suggest. abt tonnage and weather to go for inverter split 5 star or simple 5 star. city gurgaon

Abhishek Jain (Mod)

If you want to reduce the heat in the room you can check more on the insulation section on this website: https://www.bijlibachao.com/save-electricity/insulation

19
Abhishek Jain (Mod)

Hi Manav,

It is very important that you understand how an AC works and it will be great if you can read the writeup on this page: https://www.bijlibachao.com/air-conditioners/air-conditioner-work-laymans-explanation.html

Secondly there is a rate at which AC takes out heat and there is a rate at which heat comes in the room (heat coming from outside, heat from appliances, heat from people, etc). The temperature will normalize when heat coming in the room balances heat being taken out of the room by the AC. The normalized temperature will depend on the heat load in your room and the cooling capacity of the AC.

An AC having minimum temperature of 16 degrees does not mean it will reach 16 degrees. Just like your car shows maximum speed of 200-250 kmph does not mean it will be able to reach that speed. It will all depend on the load on the car, engine capacity, etc. Similarly the temperature will depend on the heat load and cooling capacity.

When sizing of an AC is done, it is assumed that it should be able to bring down the temperature to a comfortable 25 degrees in a reasonable time of about an hour or so. But at what temperature does it settle to, depends on heat load in the room and cooling capacity of the AC.

As per my calculation, your room needs about 1.8 tons of cooling. Which is about 6300 watts cooling capacity. So you should look at an AC that has that kind of cooling capacity. Otherwise it will take much more time to reach 25.

Now if you go for a 1.5 ton inverter AC then most common 1.5 ton inverter ACs can reach at max to 1.7 tons cooling capacity. It should work perfectly fine during nights and non peak summer days. But if you want to handle peak summer day time as well, then you need something that can get to 1.8 ton.

Usually most 1.8 ton ACs are marketed as 2 ton. Only brands like Hitachi, Mitsubishi have true 2 ton ACs. All other brands (LG, Voltas, Blue Star, Carrier, etc) have 1.8 ton ACs marketed as 2 ton.

The reason you need more cooling capacity is because you get lot of heat from roof and walls.

1st n top floored duplex, room size 16*11=176sq.ft., no any side wall exposed to direct sunlight, window(north facing) well insulated all doors. For above configuration i had chosen 1.5 tonnage Godrej GSC 18 FFZH 3 RWPH 3 Star Non-Inverter A/C... its right choice?
2nd question...using for night abt 8 hours setting temp of 28-29℃ n auto fan mode, i m residing in Vadodara city, Gujarat. As an assume... How much units will it consumes? Any other using tips? Plz. As ur valuable suggestions will worthy for me.

21
Abhishek Jain (Mod)

If you need it for a lower floor room then 1.5 ton would be fine. Else you will have to go for 2 ton. It would consume about 1-1.2 units in an hour. So in 8 hours it would consume 8-10 units.

22

Sir I have o general 1.5ton 3star window ac.my flat is on second floor .how many unit electricity consumption every hour if desire temp is 25'c....pls tell me

23
Abhishek Jain (Mod)

It would be about 1.2-1.3 units per hour at least.

24

Thanks sir for Ur help.
Dry mode me bhi same consumption hoga kya? Pls tell me

25
Abhishek Jain (Mod)

Dry mode mein compressor zyada chalega to consumption zyada hoga.

26

My ac EER is 2.98
I live in Delhi

27
Abhishek Jain (Mod)

Difficult to tell exact number. But as I said, it would be about 1.3 units per hour.

28

Sir pls ye bhi batana ki 10*10 k room size k liye 1.5 ton ka ac lekar koi galti to nahi ki hai

29
Abhishek Jain (Mod)

10x10 room ke liye 1.5 ton AC kaafi bada hai. To thoda to electricity consumption zyada hoga.

30

My room size is 10*10

Hi Abhisekh,
I purchased Sharp 1.5 ton inverter ac in 2015. The EER is rated 4.41 & power consumption is 1480 watts. I would like to know a few things.
1. what is the EER of my ac if calculated in 2017?
2. Now a days inverter ac is labelled with star ratings. In that case what is my ac's star rating?
3. If i run my ac for 8 hrs a day, how much electricity will it consume? (units)
Reply is expected from your part.

32

*** No reply?

33
Abhishek Jain (Mod)

Here is my response:

1) EER will remain the same because EER is cooling capacity divided by power consumption. And that will remain the same.

2) It would be BEE 4 or 5 star rated Inverter AC as per current labeling standards. Most likely it would be BEE 5 star as per current standards.

3) It should consume about 4-5 units in 8 hrs of usage.

34

Thanks for your reply.

35

thanks bro,

one more thing off timer I use on Hitachi inverter ac .. if I set say 4 hrs some days it gets off correctly .. some days it gets delayed up to 1hr or more... what could be the reason..

36
Abhishek Jain (Mod)

No idea. You will have to check with Hitachi.

37

Hi abhishek, thanks for ur site and articles,
our bed room is 10*10 , only one floor, so roof is exposed to direct sun light and glass window usually closed facing east.

we are using Hitachi 1.5 ton inverter ac for the last one month keeping 26°cool mode, or auto mode.. indoor unit is installed at above 9 ft...
the doubt I have is which position the swing is to be kept ... whether direct cool air can be faced by us or swing position is to face some what above us while night sleeping...
thank u

38
Abhishek Jain (Mod)

It depends on what is more comfortable to you. Ususaly if the air flow is more towards the ceiling, it helps cover more area. But then you need to feel comfortable. So it is absolutely fine if you keep it towards yourself.

39

hello i have kenstar 1 tone 5 star ac before ac my bill was 2 to 300 after instaling AIR CONDITIONER now my bill is 1500 im common man iam shocked with bill and i use everytime 26 temperature only still why bill is so high can u pls help me out..

40
Abhishek Jain (Mod)

How many hours do you use the AC for in a day? And which city are you from?

41

Hii,
I have purchased Window AC 1.5 ton for delhi and I am running it to 28 degree, as iam finding this temp comfortable,But many People are telling that , setting the temperature higher i.e. 28 Degree , will cause Compressor to malfunction.
Is this true , that setting the temp higher(28 Degree) damage the compressor.

42
Abhishek Jain (Mod)

It will short cycle and will have less efficiency. But still it will consume less electricity as the temperature is high. I do not think it should malfunction just because of that.

43

Thanks you Very much.

Please guide to Calculate power consumption of AC.

I've 3 Star Rating Hitachi AC.

Thanks You Again..

Abhishek Jain (Mod)

What is the tonnage?

45

1.2 ton & Set temp 28 degree 7-8hours..what happen? Please Reply..Thanks you...

46
Abhishek Jain (Mod)

The AC will cool the room to 28 degrees. Electricity consumption would be low.

47

Hello, I have set split AC temperature cool mode 25, and after 2 hours when I have check room thermostat temp. 25•c and thermostat temp have not go down from 25•c. So compressor also not off so light more consume so please let me know what is the problem.

48
Abhishek Jain (Mod)

You will have to call up the helpdesk of the manufacturer to check if there is any fault. Difficult to say anything without checking it.

49

Hello,

In my experience the best method to lower consumption from ACs is to regulate usage. Ofcourse setting the device to 25 Degrees can help but nothing close to when its shutdown when not in use. There are many smart devices that can help you with this.

Hi,
I brought Panasonic split ac yc12sky4 1 ton 4 star yesterday and running very nicely. I am living in kalyan and in ground floor where no direct sun facing. My room size is 14 *9 feet. i feel cold at 24 degree temperature so i kept 28 and kept running for whole night and i found very comfortable at 28 temperature. what should i do to bring down my electricity bill.

53
Abhishek Jain (Mod)

Keeping it at 28 (or high temperature) is the best to bring down electricity consumption. So you are doing good.

54

Hi Abhishek,

I am from Hyderabad. Room size is 12(l)*12(b)*10(h). It's a 4 storey building. We are in 2nd Floor. One side of the room is Noth-Eastish. Therefore direct sunlight on that one wall from noon (But with reduced intensity due to a tree). Outdoor unit is at East, no direct sunlight at all to it.

Our usage is mostly for nights (10pm to 8am), except on Saturdays & Sundays. Mode used is always "Cool". Fan speed sometimes 'Slow' & sometimes 'Fast'.

A month back I have bought a Mitsubishi Heavy 1.1 Ton 5 Star Fixed speed AC (Model : SRK 13 CRS-S6). After using for 1.5 months, I have certain queries and need your inputs on the same. My future AC decisions will be based on your inputs.

1. Firstly, did I choose the right tonnage for my room?
2. At nights, the cut-in & cut-off cycles might be good (ranging anywhere from 7min to 15min per cycle depending on temp setting of either 26c / 27c / 28c). But cycles apart, the initial cool down takes a long time even at 10pm, say around 1 to 1.5 hrs, not sure. Is this something to worry?
3. Now during weekends, in the afternoon, setting at 26c, I feel the AC takes a long long time. It pleasants the room but the compressor doesn't cut-off even after 1.5 to 2 hrs. I observed this yesterday at 4:40pm. Compressor was running nonstop until 6:40 and then I switched it off. Is it undersized or any other issue?
4. Also, is it worth spending the extra money for the brand? Will it be so different from others? Bcoz it costed 41,000 incl of everything for this 1.1 ton 5 star. Other brands are so so less priced. Even the good brands like Panasonic are cheaper compared to this.

Your inputs please.

55
Abhishek Jain (Mod)

Hi Arjun,

Your room's tonnage requirement is coming out to be 1.2 ton. So 1.1 ton should work fine, especially because MHI ACs have long air flow. So it should work fine. It should have worked fine. It is quite possible that it is not installed properly. Otherwise 1.1 ton should have worked perfectly fine for your requirement. You should put a complaint with MHI for the same. Does it not cool fast when you keep fan speed high?

56

Hi Abhishek,

Thank you confirming on capacity.
No it did not cool any faster when the fan is kept at high speed. My observation that I mentioned is actually done at high speed. But looks like there is no issue with the cooling as such from the machine. Air is quite cool that is coming out. I will check it once by speaking to the MHI person.

57
Abhishek Jain (Mod)

Can you check the temperature of the cool air coming out? If that is cool enough (between 6 and 10 degrees) then the room should get cooled. I hope the room is packed enough so that no heat in coming in from any point. Are the walls hot? or are the windows open and hot? Is the door closed?

58

Hi, I don't really have any device right now to check the temperature of the air coming out. Will try to ask someone for a device.
Doors at kept closed but there is some gap (about half cms) below the two doors connected to the room. Will now try closing it by with a cloth and check the cooling.
Yes the wall and 2 windows to it are hot as it's slightly north-west and faces heat post noon.

59

Does inverter ac work efiiciently at temp upto 42 degrees and does not cool efficiently above this outdoor temp I live in Jhansi where outdoor temp can go upto 49 degrees its semi arid zone mostly dry round the year with annual average rainfall of 800 mm

60
Abhishek Jain (Mod)

You will have to check the operating temperature of the AC. There are many brand that have ACs that can work easily up to 50-52 degrees as well.

India ac 4hrs 8

My india ac 3star 2 unit per hrs bijli consumpson

62

we recently installed a blue star 1.5 ton 3 star split AC (BI-3HW18FBTU) at our residence in Tamilnadu (with max temperatures of around 40c). The room size is 13x09 ft with one exposed wall facing east, situated on the first floor of a 3 storey building. we operate the AC usually from 10 pm to 6 am, at 26c temperature in cool mode. While it does cool the room well, we have been having a few concerns regarding its power consumption. Prior to the installation of AC, our daily consumption was 6 units, which has jumped to around 14 units now (So, approximately 8 units for 8 hrs during night). Additionally, there appears to be malfunctioning of AC in terms of cycle duration. After initially taking around 30 minuites to attain the set temperature, the compressor stops for exactly 3 mins. It restarts and run for 8-10 minutes and stop for 3 minutes .The cycle gets progressively shorter over the next 2 hours to a point where it runs for about 4-5 mins and stops for 3 mins, then starts again. Is this normal functioning l. Your opinion would be much appreciated.

63
Abhishek Jain (Mod)

Hi Sevaraju,

8 units for 8 hours for a BEE 3 star rated 1.5 ton AC sounds quite reasonable. If you wanted it to be lower then you had to go for a more energy efficient AC. Also 9-10 mins cycle is ideal cycle for any AC and if it is achieving that, then it is running at good efficiency. The efficiency goes down as the cycle time goes down. But then you cannot do much about it. Inverter Tech AC would have reduced the electricity consumption. But then this is a normal AC. The cycle time would have been longer if you would have gone for a 1 ton AC (which was ideal size for your room). But I do not think this AC is abnormal. It is behaving how a 1.5 ton BEE 3 star rated split AC would have behaved.

To cover almost 400 sqft hall (domestic purpose) , Usage 3-4 hours a day and for 4 to 5 months ,some friends suggests me to fix 2 acs of 1.5 tons & 5 Star ratings of Blue Star , Model 5HW18ZCWX. Is it right to bought it , pls suggest me

65
Abhishek Jain (Mod)

Hi Sandeep,

Firstly the right tonnage requirement for a room depends on multiple factors like city, room location (if it gets direct sunlight from walls/windows/ceilings etc) and the room size. I cannot comment if 3 tons will be sufficient for your room or not. You can check the same using the calculator on this link: https://www.bijlibachao.com/top-ten-appliances/best-air-conditioner-ac-window-split-hitachi-lg-carrier-samsung-electricity-consumption-tonnage-in-india.html

My guess is that you would need 3 tons or more. So you can certainly fix 2 ACs of 1.5 ton. Blue Star is a great brand and you can certainly go for Blue Star 5 star rated AC.

66

i have an inverter ac lg dual inverter 3 star when i set temperature at 20 in remote the room temperature will be at 23 and if i kept in 23 in remote and room temp will be 26 always 3 or 4 degree difference, is it normal for this type inver ac?? ac technician says its normal but im not satisfied with his ans.

67
Abhishek Jain (Mod)

Hi Chandru,

A lot depends on where you are measuring the temperature. The thermostat of the AC is inside the indoor unit and so you will have to check the temperature at the grill (or close to the indoor unit).

68

thank you for ur reply i kept running the lg dual inverter ac 1.5T for more than an hour in room size 9*9,
i checked the temp in remote for room temperature and also i have a separate thermometer for room temp both shows 3 to 4 degree diff as i said earlier.

69
Abhishek Jain (Mod)

Try comparing the grill temperature.

Can i run my hitachi split ac 1.5 ton, 5 star at 29c mode,?

71
Abhishek Jain (Mod)

Sure you can. There should be no problem.

72
NITYANANDA SARKAR

My hitachi split ac model no RAU518ADV. 1.5 TON 5 STAR. At night I am feeling comfortable to run it in 28c mode. Please let me know will it be harmful for my ac. should i run it at 24c- 25c?. please help me with your suggestion.

73
Abhishek Jain (Mod)

You can run it at 28. There should be no problem.

74

I just recently bought a DAIKIN inverter ac. I would like to know the optimum temperature that is to be set during sleeping at night. I have already used the ac for a few days @ 28 C, which I am finding comfortable. Some people are recommending that operating at such a temperature would adversely damage the compressor, IS IT TRUE?? Plus I'm also aware that the compressor of an inverter ac does not stop operation when it has reached the set temperature and it continues to operate at 21-34% power.

Regards

75
Abhishek Jain (Mod)

Hi Nirmal,

Running AC at 28 degrees will not damage the compressor (specially when it is inverter AC). You can run it at a temperature as high as it is comfortable for you. Ideally we do not suggest to go below 25. So 28 is fantastic.

76

Dear Abhishek
Thank you for your quick response. Further, I would like enquire about another issue. The DAIKIN AC that I'm using "JTKM50SRV16", runs from 12am to 5am and is consuming 1.5-2 units as recorded on the meter provided by CESC (KOLKATA) [Plus there are no other appliances running during that period of time on that meter]----- is such consumption 'ok' for a 5.2 rated ISEER rated inv ac??

Also I also set the off timer at 5am before sleep but do not turn of the starter and the MCB until 8am. Please tell me will such a practise consume any energy for those 3hrs (from 5am - 8am).

Regards.

Hi Nirmal,

As per the data by BEE for JTKM50, it will consume 744 units in 1600 hrs (this is in test conditions). Which comes to 0.465 units per hour. So in 5 hours it should consume 0.465 x 5 = about 2.3 units. But this is average because electricity consumption is seasonal. And also depends on heat load of the room. If heat load is less, it would consume less as the number is in test conditions. So 1.5-2 units for 5 hours is fairly fine for this AC.

Also if your AC switches off, it will not consume any electricity. It may probably 1W or so for the LED kept on. But not much.

What I bought I mean some friends suggest me for 2 ton & 5 stars rating ....
Is it fine ?
Kindly reply me I have to bought it by today & kindly suggest some recommended brands also.

79
Abhishek Jain (Mod)

2 Ton would be small for 400 sq ft space in most cities in India. If you want to cool the whole room, then you would need more. But if local cooling close to the AC is fine with you then you can go for 2 ton as well. Let me know your budget and I can suggest something accordingly.

80

Sir budget is somewhere around 50- 55 K .
Is 5 star is good for my purpose ?
Kindly suggest some good brands accordingly...

81
Abhishek Jain (Mod)

Hi Sandeep,

Hitachi would be the best brand in terms of cooling and energy efficiency. You can look at these models:

Hitachi RAU524AVD (Amazon Link: http://amzn.to/2pXTUo5 )
Hitachi RAU524MWD (Amazon Link: http://amzn.to/2pY2PWJ )
or you can look at Blue Star 5HW26AAX ....

These are ACs with BEE 5 star rating and highest in cooling capacity.

82

Hi Abhishek ,

Pls suggest me the AC for 400 square feet hall....kindly revert me in priority am in hurry.

83
Abhishek Jain (Mod)

Hello Sandeep,

At Bijli Bachao, we suggest this strategy: First find out the right tonnage that you need for you room, because undersized AC may not cool well, and in case of non inverter AC, oversized AC can significantly increase electricity bills. In inverter ACs, slight oversizing is fine. You can use the calculator on this page to get the right tonnage: http://bijlibachao.com/top-ten-appliances/best-air-conditioner-ac-window-split-hitachi-lg-carrier-samsung-electricity-consumption-tonnage-in-india.html

After finding the right tonnage, you have to look at your usage of AC in hrs/year. And your budget. Because your usage determines if you need high efficiency AC or not. Secondly we try to suggest the most efficient AC based on a person's requirement (tonnage requirement) and the budget.

Let me know the right tonnage (as per the calculator) and your budget and I can suggest you some models accordingly.

84

hi,

I have voltas ac of 1.5 ton. I just wanted to know what are the steps to set the compressor will start again when the thermostat detects that the temperature has increased.

Please do reply me.
Thanks.

85
Abhishek Jain (Mod)

There should be no manual step needed to do that. Your AC should automatically start when the thermostat detects that the temperature has increased.

86

But how first we need to set then only it will work automatically

87
Abhishek Jain (Mod)

Just press the "on" button and it will work automatically.

88

Using inverter ac . when i set temperature at 27 degree it runs at 27 for few hrs then it goes up to 23 and then coming down , not always but some times . i dont use swing . i check temperature on my ac remote which is kept direct ac air flow.

89
Abhishek Jain (Mod)

It should not happen like that. I would suggest that you log a complain with the manufacturer.

90

I have a cyber cafe with Ac 1.5 ton and 3 star rated, Can I on the Ac only when the customer comes in and when the customer is not there, can I off ... will there be high impact on the bill if I do this .. Please reply

91
Abhishek Jain (Mod)

As long as it is not too frequent (like every 5 mins), it should be perfectly fine as long as the customer is comfortable :). Because when you switch it off the shop will become hot.

92

Hi i have 1 question,I have 1.5 Ton fixed speed split AC, Recently I found my AC is not chilling the room as it was doing earlier on 24 degree. Today I took thermometer from local ac mechanic and test the room temperature,I have set my ac at 24 Degree but it cutoff at 24.8 degree and started again at 27.4 degree is it normal? or it should be cutoff at 23 Degree ? should i complain to service centre for this? I stay in Jogeshwari(W),Mumbai.Please reply.

93
Abhishek Jain (Mod)

Hi Faiz,

Did you try getting the maintenance done for the AC? Usually dirty filters, etc cause cooling performance to reduce.

94

Yes i have cleaned my filters. But I want to know how sensor work I heard if we set temp to 24 ac should cutoff at 23 is it true?

95
Abhishek Jain (Mod)

It should cut off below 24. Not above 24.

96

Thanks Abhishek. It means my ac sensor is not working properly will lodge a complaint. Thank you so much.

97

What is your take on ACs in Multi level buildings? Especially in IT offices.

98
Abhishek Jain (Mod)

A VRV system works great in a multi level building.

99

kindly suggest best power saving and long life performance with lowest maintenance ac with suitable tonnage for 9*9*9 room in airoli navi mumbai, my room is on 2nd floor in 5 storage building 1 wall with window is facing east so sun rise to noon it is taking direct sunlight, usually we will be using ac at night only, as nobody at home whole day, once or twice in a week day use. Kindly suggest brand and model.

100
Abhishek Jain (Mod)

A 0.75 ton AC would be more than enough for the room. Airoli would be slighly corrosive area as there are chemical factories due to the thane belapur belt. I would suggest copper condenser fixed speed AC. I would say, any of these would be good:

Mitsubishi Heavy SRK10CRS-S6 (this will have better air flow and so better coverage of the area)
Mitsubishi Electric MS-GK10VA (Amazon Link: http://amzn.to/2pJvFYX )
Blue Star 5HW09SAFU (Amazon Link: http://amzn.to/2pckRl6 )

101

thank you abhishek sir for prompt revert, no inverter is required ? stabalizer is recommended? as here electricity cutoff. how about ac from new companies like micromax

102
Abhishek Jain (Mod)

You can go for inverter AC if your environment is not very corrosive. I have a 0.75 ton inverter AC from panasonic in Powai which I have been using successfully for past 4 years now. But then I have heard complaints of PCB failures from people living close to the sea where direct winds from sea causes corrosion. So if the area is corrosive, I usually do not recommend Inverter AC. Only when the area is not corrosive, do I suggest going for inverter AC. If you want to go for inverter AC then you can look at these:

Blue Star 5CNHW09PAFU (Amazon Link: http://amzn.to/2n5TMS0 )
Daikin FTKP25 (Amazon Link: http://amzn.to/2p6E4IU , Flipkart Link: http://fkrt.it/GNdWcTuuuN )
Blue Star 3CNHW09CAFU

Stabilizer is usually recommended when there are lot of voltage fluctuations. Power quality is quite reliable in Mumbai and usually Stabilizer is not required in Mumbai. If you feel that you get voltage fluctuations in Airoli, then you can go for a stabilizer. You can check this page for voltage stabilizers: https://www.bijlibachao.com/appliances/voltage-stabilizers-buying-guide-best-tv-ac-fridge-home-guide-india.html

As for micromax, I would say that based on data, they are not very energy efficient. And then they do not have 0.75 ton AC. In fact they do not even have a 1 ton AC. They only sell 1.5 ton ACs and those would be highly electricity consuming in your case.

103

what are the consequences if for smaller room size we install more tonage AC for 9*9*9 1 TON or 1.5 TON AC

104
Abhishek Jain (Mod)

Oversized ACs: 1) Consume more electricity 2) Are not effective in removing humidity. If you go highly oversized like 1.5 ton then you will also observe bad odor from the AC. And on top of it you pay more to buy it.

It is like if you need a car and you purchase a truck. Truck consumes more fuel, and costs more!! And you have loads of space left in truck which is unused.

105

sir can I go with these 1. ac Cruise 1 Ton 3 Star Split AC (Copper, CWCACC - CQ3CN123, White) 2. Hyundai HS4G33.GCO-CM Split AC (1 Ton, 3 Star Rating, White, Copper) they are on amazon can I order it online , is it safe ?

106
Abhishek Jain (Mod)

You can certainly buy online. Just make sure that the seller rating is good on Amazon. I checked the ratings:

For Hyundai Model here is the link to seller ratings: http://amzn.to/2rdyzEO ....I can see only 1 seller for Mumbai and his rating is 46% (kind of low).

Cruise model comes from Reliance Digital Express (Seller Page: http://amzn.to/2rdqW1t ) .... the rating is good. So I think Cruise model is safe.

107

Hi,
I have purchased 1.5 ton window ac for my 12*13 room in Gurgaon (Roof is covered by top floor and sun light faces only one side of room after 2 PM , is the tonnage correct in over/undersized, I am planning to move another place in noida , which has 10*10*9 ft bedroom , so is my AC oversized for it.

108
Abhishek Jain (Mod)

For your current room it is rightly sized. But it will be oversized for your next room. For the other room anywhere between 0.75 to 1 ton is good.

109
Abhishek Trivedi

Hi Abhishek,
Does the compressor automatically on and off after some time ? Is this normal procedure?

110
Abhishek Jain (Mod)

For non inverter AC, yes it is a normal procedure.

111
Senthilkumar Shanmugam

Hi, In my room i have a daikin 1 ton inverter Ac, What is the ideal temp for inverter type ac, 25 feels too cool for me, If i set my ac to 28, will i save more electricity.

112
Abhishek Jain (Mod)

You will certainly save more electricity if you keep it at 28.

113

Thank for this article I was looking for ways and reason to why my electricity bill has increased this year. I landed up on your website. After reading the article and comments. I put my AC on 24 C temperature. And its the same feeling I was getting when It was on 16C. I don't know why I was putting it at the highest temperature. I am hoping this itself would reduce my bill
I have a few doubts though could you please clarify. I have an old LG 1.5 ton Window ac(room is 10x10 feet) I was able to keep my ac bill around 3000(normal bill is 900 to 1200 w.o ac) and in peak summer 3500 per month. I used to use an energy saving feature on it. Where if you turn it on the AC will automatically switch off totally when the desired temperature was reached.
If i kept it around 26 It would sometimes work but sometimes the rest of the room wont get cooled. It would turn off as the temperature near the ac would reach 26. I tried keeping fan slow it would work sometimes. If I keep it at 24 it would turn off after long time. Now I just keep a timer for 2 hours or 3 hours and then hope the temperature stays ambient till I wake up.
For some reason doing the same this summer got me a whopping bill of 3700 rupees. I have been keeping it on for around 6 hours a day(at 16C) Otherwise normally I get around 2700 then 3000 and the peak month around 3500.
I am scared that in the next month it will cross more than this.

My First question is Now will keeping it at 24C reduce my power consumption.?

I just noticed that after keeping in on 24C even though the AC is not energy saving mode(which for some strange reason can only be turned on from the remote) there is a change in the sound of the AC after a few minutes. I sit next to the AC and am noticing that the air is not that cold. But the fan is still running.
So it seems like the compressor or the cooling part has been turned off.
Is this good?
Or is the energy saving mode better? In the energy saving mode the entire AC turns off with the fan. But it turns off after long time and only if the fan is kept slow. Here in the normal mode the compressor seems to turn off and turn on at equal intervals it seems like after 5 minutes it turns of the compressor for 5 minutes. The fan is running all the time.
Second question is is this normal better or is the energy saving mode better where the AC will totally switch off but at longer interval and it gets turns of pretty fast especially if fan is even in Medium.

Third question Is to confirm what my AC guy said.
he told me my Ac is using 8amps power. Its too high he told me to change the ac. Last year it was using 6amp. He told me a split ac will only use only 4 or 5 amps. So my power bill will become half.
Is this true? Will a split AC give so much efficiency.
Also My room is 10x 10 and the ceiling high is 10feet I had asked him if a 1 ton AC or a .74 tonn ac is enough. He says I need 1.5 tonn.

I still did not go in for it as my logic was that I have to spend 15K which he said uses only 5amp.
If this would even cut my powder bill by half. I would be saving 1500 per month max
That would take me 10 months to recover my 15k That i put to purchase. I use the ac only for 3 months a year. Maximum you can say 5 months As I use it for for another six month but the bill only comes up to 1k extra So I would be saving only 500.
Even if I ended up saving with a 5 star ac a new one 2k It would still take 15 months to recover the money put into my AC.
SO I decided to postpone it till I move out of my house. Which I would shortly and then invest in a nice 5star costly AC that would at least run for a couple of years so that I am able to recover the cost in saving and also get extra years savings.
Is my logic correct.? I had to spend 2500 rupees for servicing of the ac fill gas etc. This is when he recommended I don't do it and spend 15K instead.

Thank you

Abhishek Jain (Mod)

Hello,

First and foremost, your AC is oversized. I do not think you need more than 1 ton AC for a 10x10x10 room in Mangalore. In fact I think 0.75 ton will also be better. Because 1 ton is required for 100 sq ft room in Delhi where the climate is much hot. So in your case I think even 0.75 ton would be better. And oversized ACs do consume more electricity.

Also you will save electricity if you keep your AC at as high temperature as it is comfortable. So if you keep it at 26 and it is comfortable, then it would be the best. If you can go higher, it would be better. But because your AC is oversized, keeping it at higher temperature would result in short cycle and that would also reduce the humidity removal capacity of the AC and increased humidity can cause bad odor. So you will have to manage temperature in such a ways that you can keep it high and also avoid bad odor.

As for energy saving mode, I think it is a good mode where the AC is completely off for some time. But then it may lead to increase in temperature in the room which may not be very comfortable.

In the market you can get inverter technology split ACs which would be about 50-60% more electricity saving that your current AC. In fact you may even go for 0.75 ton inverter AC which would be hugely energy saving for your room. But then it would cost about 30K to get a new AC. But you will certainly notice a huge difference in your electricity bills.

Also in any house the electricity consumption of various appliances go like this:

1) AC is the highest contributor to electricity bills.
2) All Fans together are the next highest contributor.
3) Refrigerator can be a third big contributor specially if you have a big one.
4) Water Heaters/Geysers are 4th biggest contributor (or can be 3rd if refrigerator is not big).
5) Lights and other appliances are the last.

If you can tackle first 3-4, then you can bring down your electricity bills by huge quantity. There are energy efficient options for each of them. And the most efficient options can save 50-70% on each.

Mangalore Cafe

Hi,
Thanks for the prompt reply. BTW I am from Mangalore But living in Surat. Temperatures can reach 40 and above in peak summer.Its been 2 days Since ur message and no odour problems.
I have a tip to take care of odour I simply buy some pure camphor powder. I just throw it into the the ac It sits between the grill and the filter and it purifies the entire room and keeps the AC also from smelling due to bacteria overgrowth.
I will put it on energy saving mode and see how it fares.

Thanks for the confirmation I knew that a 0.75 ton AC would suffice. I wonder why these AC mechanics and Seller recommend Higher ton AC. In some places they recommend 2 tonne acs where I am sure only 1 ton is enough.

I just wanted to confirm will a 0.75 ton window AC give me a reduced power. I have seen models with 5 star and 3 star rating But I am not sure how easy it would be to procure it. They cost only 20K There is a bluestar 2star AC for 19k Will this 2 star and I have seen other 1 star ac give me at least 50%

116
Abhishek Jain (Mod)

Window ACs are outdated. They do not have latest and efficient technology. It will be better if you can go for a split AC of BEE 3 star or above. Inverter AC would be highly electricity saving and comfortable as well.

117
Mangalore Cafe

Thanks a lot I think I should think about investing in it.

118

Dear sir,

I recently bought an AC. The installation guy who came kept on telling me to keep AC temperature in odd figure. He gave me a reason that, in odd figure power consumption would be reduced. Can I believe that.?? Being a service centre guy telling me I was concerned so I took the matter to you.

Thank You

119
Abhishek Jain (Mod)

There is no logic behind keeping temperature at odd figure. You can reduce power consumption by keeping the AC at a temperature as high as it is comfortable to you.

120

Thank u sir

121

Hi, I have an Electrolux Split AC 1.5 ton bought in 2015. I used to live in Gurgaon where my room size was pretty small as compared to my current living place, As I have got it installed this season, it is taking longer periods to cut off the compressor and runs for almost 1,5 hrs. I have called up an electrolux engineer and he told me it is of no issue and it happens because I have a sun facing apartment and the size of my room is bigger than previous one and my outdoor unit is in the place where it gets sunny in the noon time. Earlier my AC used to take cut cycle of 20 mins or 30 mins extended to 1.5 hrs now. I am worried about the same. How can I prevent it? Will it consume more energy now?

122
Abhishek Jain (Mod)

Hi Sunny,

Do you mean that the compressor now shuts off after 1.5 hrs? That's a real long time and it would certainly mean it would consume more electricity. What is the size of your room now in Gurgaon?

123

The cycle of taking cut offs of outdoor unit I meant

124

14ft by 14ft and height 12ft, yes it takes cut off at 1.5hrs.. i do not understand why? any help would be appreciated

125
Abhishek Jain (Mod)

Hi Sunny,

Based on the information you have provided, your room needs 2.5 tons of cooling in peak summer day time. So it is very well understood that cut off will be quite long. It will certainly consume more electricity than what it used to do earlier because the load on it is much higher. Also the outdoor unit is facing the sun which make it more difficult for the AC. So all in all, the performance has taken a hit because the heat load is a lot more.

126

Hi abhishek,
I am from delhi and have voltas executive split ac of 1.5ton
My room size is 10x14x10 feet
14 x10 feet wall is sun facing and absorbs heat whole day. Similarly 14x10 feet roof exposed to sun whole day as room is on top floor.
My room ambient temp. Comes to around 37 degree and out side temp is 42. My ac drops the temp by 8 degree in 30 minutes and further 2-3 degree in another 30 mins or so. In all temp drols from 37 to 26 in one hour or so. But after that it struggles to drop temp further and brings down only 1-2 degree after running for couple of hours.
Grill temp. Is about 12-13 degree.
Is my ac working ok and heat laod is too much to reduce the temp further.
In nut shell my my ac drops only 12-13 degree lower than room temperature irrespective of outdoor temp. Pls advise
Regards
Kunal

127

Thx Abhishek. I agree with you.
But my in peak summer room temperature goes as high as 38_39 degrees and than ac struggles to bring the temperature to 28-27 degrees even after running it for 2 hours or more. Is it due to extreme heat or there is some issue with C due to which it manages to reduce pnly 10_11 degrees only at any point of time.
Also at the outer unit temp of both the lines (sucction line the wider one and liquid line the narrow one) are indetically chill. I have read some where that liquid line should be warmer. Is that an issue

128
Abhishek Jain (Mod)

You can try reducing the heat in your room by getting the roof painted white (with chuna) on top if you have access to roof top. This will significantly reduce the heat in the room. If you do not have access to the roof then you may put a XPS (Extruded Polystyrene) thermal insulating board on the inside on the ceiling. This can act as false roof and can also reduce the heat in the room.

129
Abhishek Jain (Mod)

Hi Kunal,

As per my calculations your room needs 1.5 tons cooling (exact 1.5 ton) or max 1.6 ton if the walls also get heated up (along with the roof). Now I am not sure which executive split AC do you have (they have window models and split models of 2 star, 3 star and 5 star ratings), but I checked the various models and found that the 2, 3 star rated models (both split and window) have cooling capacity equal to 1.37-1.38 tons. And their BEE 5 star rated models have cooling capacity of 1.43 tons.

Whatever be the model, its tonnage may be a bit small for the room's cooling needs. And that may be the reason that it is not able to bring down the temperature in peak summers to 25.

And the gas line should be warmer because the refrigerant will take heat from the room and the liquid refrigerant will convert to gas. But liquid refrigerant coming in should be cool.

130

Hi abhishek,
Many thx for your reply.
Its volats Ex AY 185 5 STAR MODEL.
YES In peak summer my room feels like tandoor and specialy in the evening when outside temperature falls, rooms temp still remains high due to heat absorbed by roof and west sun facing wall. Also my room do not have proper ventilation.
But from your reply i understood that ac is fine and romms is getting excessive
Heat.
Thx

131
Abhishek Jain (Mod)

Hi Kunal,

Firstly I think 24-25 is more than comfortable temperature. Ideally when an AC is sized, the calculations are done in such a way that the AC tonnage is such that it should be able to bring down the temperature of a room to 25 degrees. So if your AC is able to bring down the temperature to 25, then I think it is right sized. I think 1.5 ton should be good enough for 140 sq ft room in Delhi (even the one with hot roof). Frankly I do not see much of an issue with the AC.

P.S: There are people trying to come up with laws internationally to keep default minimum setting in ACs to 25 degrees and not lower than that :). Because this is temperature which is quite comfortable and the AC does not consume a lot of electricity.

132

Water droping from my ac inside bedroom for the first time. Installed ac before 2 months. why is it ?

133
Abhishek Jain (Mod)

Your installation was not proper and the water draining pipe may have clogged or choked in such a way that the water is not going out. Ask the engineer to check drainage pipe.

134

I bought a Lloyd LS13AI 1 ton inverter AC for my child bedroom. It was installed yesterday. I have a couple of questions.
1. The outdoor unit is kept below the level of indoor unit. Is this an issue?
2. Outdoor unit is exposed to direct sunlight in the afternoon time since it's placed under the west side window. It's under a sunshade, however I think it's still exposed. Is this an issue?

Thank you for the help in advance.

135
Abhishek Jain (Mod)

Here is my response:

1) It should not be an issue.

2) It is better that the outdoor unit is not exposed to sun. A lot depends on the operating temperature of the AC. If it is 46 and the temperature in your city goes to 48, then the outdoor unit may not work in peak summer (especially when exposed to direct sun). If it is 50 or 52 then it should work without problems. Check the user manual.

136

Ok..Sure..Thanks for your help!

hello Abhisek,
I have 1 Ton 3 star Voltas split AC bought in 2009. Since last 1 year it has developed a peculiar issue. Out door unit cut off at 27 but never cut off 26, 25, 24 or so. I have got the service done regularly and it gives good cooling for my 120 sq ft room. Is Thermostat is faulty? if so how can I change it? any other possibility for this issue ? pls guide

Thanks

140
Abhishek Jain (Mod)

ACs derate with time which means their preformance degrades as time passes. It is low in some brands, high in some other. But derating happens in every AC. It is quite possible that the performance has degraded with time. Can you check the grill temperature (Temperature of Air close to the AC) and compare that with temperature setting. Can you check if the AC is able to reduce the temperature to the levels you have set?

141

Hi.. I have purchased daikinGTC50SRV162 3 star 1.5 ton split AC with eer 3.25 in my room size 12*18 ft.... I generally use it at temp 25But it sometimes smell bad and how much units does it consume ...

142
Abhishek Jain (Mod)

Smell can be either because the AC is oversized (you put 1.5 ton when you need 1 ton) or the compressor is not running long enough. Try keeping it at lower temperature and see if the smell is still coming. Is it is new AC? In effective removal of humidity can cause mould and mildew to grow which can cause bad smell from the AC.

143

This AC was brought from a store but when I searched online this model of daikin gtc50srv162 is not available online... Pls guide me... Weather shopkeeper given me genuine AC or not???

144
Abhishek Jain (Mod)

Just noticed that BEE has included Daikin GTC50 in its list. So it is a valid model.

145
Abhijit Shrirao

Thanks Abhishek

146
Abhishek Jain (Mod)

Hi Abhijit,

I am sorry I cannot say anything on this because it is possible that Daikin has come up with a new model and they may update their website later. But there is no proof online for existence of such model.

147

Yes... It is new AC manufactured in January 2017
I am now using AC at 23 and now there is no bad odor

148
Abhishek Jain (Mod)

Use it at lower temperature as I guess it is a bit oversized and is not able to remove humidity effectively. The compressor needs to run longer to manage the same.

149

Hi Abhishekh i have voltas window ac.. outside temperature at my place is 43 now it will go up i m confused what mode i should setup for room for cooling nd comfort level

150
Abhishek Jain (Mod)

You can use the cool mode on the AC. That should be fine.
