Electricity Saving Tips For Homes And Offices

Various modes for running air conditioners and their impact on electricity bill

By on August 7, 2017

Air Conditioners in past used to be quite simple with just on/off switch and high, medium and low cool options. With improvements in technology, modern day air-conditioners have lot more electronics in it and thus they provide multiple modes of operation. Most of these modes are explained in the user manuals that come along with the air conditioners, but it is very important to understand the impact of each mode on electricity savings.


In this article we will try to explain various modes available in various air conditioners and will analyze their electricity saving potential:

Cool Mode

Cool mode is the regular or default mode in which the air conditioner runs as per the temperature setting and fans speed at which it is kept. Electricity saving potential in this mode depends on the temperature set in the air conditioner. Ideal temperature for thermal comfort and electricity saving is 25 degree centigrade (more details in our article: Ideal Air Conditioner temperature for electricity savings).

Fan Mode

In Fan mode the fan runs continuously and the compressor is off. This obviously has good energy saving impact because the compressor is switched off. Compressor is the most electricity-consuming component of an air conditioner. But the downside is that no cooling happens when compressor is off. It is better to use a ceiling fan in this case.

Dry Mode

There are days in a year when the comfort is low just because of the humidity. This happens more so in case you are located in a city that is closer to the sea. It also happens during monsoons. During those days just removing the humidity of the room provides a lot of comfort. Running the air conditioner in dry mode helps as it removes the extra humidity in the air. The fan runs at low speed and compressor is on for short duration in large cycles just to remove extra humidity. This surely is an electricity saving option during high humidity days as even the fan motor is running at a slow speed and even the compressor is on for smaller duration. The air conditioner does not blow a lot of cool air in this mode, as the intent is just to dry the air and not to cool the room.

Please note that it does not work as a dehumidifier (which has potential to make the air very dry) but is just good enough to make the room comfortable.

Energy or Power Saver Mode

In cool mode the compressor shuts off when the temperature reaches the level set in the thermostat but the fan keeps running. The compressor starts again when the room temperature increases. In the energy saver or power saver mode, even the fan switches off when the temperature reaches the level set in the thermostat. So how does it help save electricity?

  • Firstly it obviously saves electricity spent in running the fan continuously.
  • The use of fan in cool mode is not just to throw cool air in the room but it also helps in taking the indoor air for thermostat to check the temperature. In Power saver mode, the fan gets switched off for a few minutes and the thus the compressor does not start till the fan switches on again to notice that the temperature has increased. This increases the time between compressor cycles thereby making it run less and thus saving electricity.

Does it decrease comfort level? If the room is well insulated, then it may not. The temperature may increase slightly (not a lot) and if that does not disturb you then it is the right mode for you to save electricity. Also because the fan switches off and on, it makes sound every time it does so. If sound disturbs you in your sleep, then this may not be the right mode for you.

Quick Cool Mode

This certainly is not an electricity saving mode. In fact it consumes more electricity. Ideal temperature for air conditioning is 25 degree centigrade, but this option starts the AC at 16 or 18 degree centigrade. If the room temperature is 35 degrees then the time it will take to reach to 25 degrees will be the same in both Cool Mode and Quick Cool Mode (with high fan speed). In fact extra electricity is spent to get it down to 16 or 18 which is not required if you like to keep temperature at 25.

Sleep Mode

The Sleep mode increases the thermostat temperature by 1 degree after every hour till it increases temperature by 2 degrees. This will help save electricity if you like to sleep at low temperatures as you save electricity with every degree of increase in temperature. If thermal comfort is your only priority it is better to use cool mode or energy saver mode at 25 degrees.

6th Sense mode (for whirlpool ACs)

The whirlpool technology adjusts the fan speed (to high, medium or low) based on the temperature of the room. It surely has a benefit over the Cool Mode as it saves electricity on running the fan motor.

Is it good to have automatic filter cleaning feature in the air conditioner?

It surely is good to have such a feature in the air conditioner. A clean filter ensures smooth flow of cold air and room air, in and out of the air conditioner. This makes sure that the thermostat is able to sense properly and thus ensuring right operation of the air conditioner thereby saving electricity.

Operating Air Conditioner in the right mode can always help you save electricity, so please make sure that you choose the right one. We will keep updating this article as we research more on the modes and options available in air conditioners with different brands.

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

Sir, I have a Samsung 1.5 ton split ac. There is a symbol (Circle formed with dots) At the top left corner of its remote. Could you please tell me what for it is? And how to operate?

2
Abhishek Jain (Mod)

Hi Praveen,

You will have to look at the user manual or contact Samsung customer care to get more information on it.

3

Sir,
Using 1.5 ton window air-conditioner with energy saving mode operation, but A/C mode doesn't switch over to energy save mode by remote or manually. Kindly suggest to bring on energy saving mode.
Regards

4
Abhishek Jain (Mod)

Your AC should have energy saving mode (either in the remote or through the AC panel) to switch it to energy saving mode. If your AC model does not have it, you cannot switch it to that mode.

Hello I have a Garrison 14,000 BTU through the wall AC in my 400sq ft studio, since the humidity is really high I decided to try out the dry mode, the air coming out was immediately frigid cold, much much cooler than on the cool mode, it cooled my studio 20 degrees in 15 minutes which is 1/3 the time it takes on cool mode on the same temperature setting, this has got me confused because everything I've read says dry mode doesn't cool as well as cool mode, maybe my unit is defective?

6

Really very helpful

7

Hello, i have 1 ton voltas ac and it didn't cool the room and recently it shows error on display like e1, e2. I can't understand what it mean. Please help

8
Abhishek Jain (Mod)

Hi Vikrant,

You will have to check the user manual of the AC to see what those errors mean.

9

i bought Hitachi Window A/C last year of 1.5. Ton with double window, the Window where A/C is installed has room behind it but we keep all the windows open and also connected one Exhaust fan to remove hot air of A/C , but yesterday i noticed Ac while working showed P- sign and it almost lessened the cooling...what could it be and the reason

10
Abhishek Jain (Mod)

Hi Charu,

You will have to get an engineer to check the same. Difficult to say anything remotely.

11

My ac GODREJ-GSC 12 GIG 5 DGOG and my area 110 sqft ground floor and temperature 34 . I set 24 c but 8 hrs need to decrease temperature . Please help me

12
Abhishek Jain (Mod)

Hello Mr Deepak,

A lot depends on your heat load and the cooling capacity of the AC. For e.g. if you room needs 1.2 tons of cooling and the AC has cooling capacity of 0.9 ton then it will take time. Ideally this AC should work well for you 110 sq ft room if the temperature outside is 34. The possible reason could be that the gas pressures are low or insulation of the pipes is not good.

13

HOw can I increase the Dehumidification temparature from 25 degrees C to 27 degrees? I want to keep my room temp at 27 degree while having a RH of about 50%. I live in a place where RH is 100%.

14
Abhishek Jain (Mod)

Size your AC properly and you should be able to get that. Oversized ACs are bad at removing humidity. Dehumidification happens in every AC when the compressor is running. In oversized AC the compressor short cycles and humidity is not maintained properly.

15

I have O genral AC of 2 ton in my Showroom , Temp. is 42' - 45 ' , If i set on 25 ' , It's not cool that much , So if we set to 22 ' , Maybe it's not automatic cut off due 250 sq. feet showroom., But it's chance to impact on AC compressor or only my electricity bill is hike for that hours ? , If only bill hike then i go for that so at least my customers not suffer , if compresser damage then we go for second AC ?

16
Abhishek Jain (Mod)

It will be better if you can go for a bigger AC. That will be better for cooling as well as for the AC.

17

"Study before you Question".
I think very few here does follow this rule. I really feel pity about Mr. Abhishek Jain. You must be needing a 2Ton to cool your head man. I have seen many silly questions asked to which I must say please guys, study more on the internet before asking silly questions. Someone here asked "why can't we run a ceiling fan+AC together in a room with a roof affected by direct sunlight?" ... seriously .. LOL you must read science books of kids. Its simple physics, the roof gets hot and ceiling fan brings down the hot air which increases the heat load of the room and the compressor gets pissed off trying to make the room temp cool.
Common guys this man, Abhishek is trying to help you so ask some sensible questions at-least for the sake of his effort and knowledge.
An really good job Abhishek Jain.

18
Abhishek Jain (Mod)

Thanks for all the understanding Ritesh. It certainly needs a lot of patience to deal with all the questions. And with time I have certainly developed a lot of it. Initially it did use to feel frustrating, but then I realized that not every person reads the text on the page and for most people it is easy just to ask a question even if the information is given on the page. It is easier to change yourself than to change the world.

19

I know that you have a good amount of patience. So good luck with your work.

20

very helpful thread, Abhishek. Thank You.

21

Thanks for ur prompt reply.
So then do they have any effect on electricity consumption means do they save or not ( turbo mode i feel)

22
Abhishek Jain (Mod)

Turbo mode will consume more electricity. But iFeel will depend on the temperature that you keep.

23

Hi. Ur website is quite informative. I m using gree 1.3 ton inverter. I want to know some functions on my ac remote control and do they help in saving energy?
1- Turbo
2 - X-fan
3 - i feel
Thanks in advance.

24
Abhishek Jain (Mod)

Hi Chohan,

i-Feel is usually there in ACs that have thermostat in the remote control as well. The AC will adjust cooling as per the thermostat in the remote. Turbo mode is for faster cooling. It will run the AC at maximum cooling capacity for good amount of time for faster cooling. Usually fan mode is one in which only the fan runs (without any cooling), but I am not sure of X-Fan.

25

Thanks a lot. The information was very helpful!

26

when a.c display shows dF what it means

27

dF means defroasting
sometime there is some water on the outlet of the indoor unit that can spill on your valuable furniture, floor etc. so some ACs have the function inbuilt to remove the excess water itself called dF mode.

28
Abhishek Jain (Mod)

No idea. You will have to check the user manual from the manufacturer.

29

How much power it draws when we run the Split AC in auto mode when compare to cooling mode?

30
Abhishek Jain (Mod)

A lot will depend on the temperature being set. Auto mode keeps varying the temperature and fan speed, while cool model has constant temperature and fan speed. If temperature set is lower then electricity consumed will be higher. And if temperature set is higher, electricity consumed will be lower. Also higher the fan speed more is the electricity consumption of fan and lower the fan speed lower will be electricity consumption of the fan.

31

I have a three star samsung 1 ton inverter ac.
I don't have ceiling fan in room so have to use ac continuously. So for a inverter ac what is the most powersaving?
(i'm at comfort at 27 in every mode. As the area i live is only warm in noon and my room has poor ventilation).
dry mode on 27 degree
single user mode on 27 degree
cool mode on 27 degree for 1 hour and then fan for 2 hrs?(comfort compromised)
and one more thing. sometimes air from ac smells bad i think using fan for 2-3 hrs causes that. it smells untill i run ac on cool mode and later use clean function. didnt knew about such smell issues because the ac is just one month old!

32
Abhishek Jain (Mod)

AC smells bad when it is not able to remove humidity effectively. Or if there is water getting accumlated which is causing moulds to develop. Get your AC checked and cleaned. Also if it is not smelling bad in cool mode then use cool mode. It should be good for power saving as well.

It is quite possible that the installation was not proper which is leading to water getting accumulated in the indoor unit. Get it checked as the bad smell comes from mould that develop when humidity removal or water removal is not proper.

33

I recently bought two Voltas 1 ton 5 star AC and placed in two bedrooms 90 sq.ft each. Presently I am using automode with temp at 25 and timer off for 2hrs. I think the consumption is 4-5 units per day. Is this the correct way to use the AC. The model of the AC is Voltas 125 ZY(410a) Zenith

34
Abhishek Jain (Mod)

Temperature of 25 is perfectly fine. In how many hours of usage it is consuming 4-5 units?

35

When atmosphere temp is 42, 44 and I have 1.5 Ton 5* Split godrej AC, how much unit in 8 hours in cool mode, AC temp set on 25...

36
Abhishek Jain (Mod)

It would be rated at about 1100 units for 1600 hrs. So about 0.7 units in 1 hr so about 5.6 units in 8 hrs.

37

Sir, if I want running AC continually for 4 Hrs, thermostat set 25temp in cool mode so how much units in 4 Hrs,

38
Abhishek Jain (Mod)

It depends on your heat load and the tonnage/wattage of your AC.

39

What is the difference of 1.5 Ton Non Inverter AC and Inverter AC, and how much solar system will require for 1.5 Ton Non inverter AC and Inverter AC?

40
Abhishek Jain (Mod)

You can read about the difference on this page: https://www.bijlibachao.com/air-conditioners/what-is-inverter-technology-air-conditioner-and-how-it-is-different-from-bee-5-star.html

Inverter ACs have low starting current because they have variable speed motor. Non inverter ACs have high starting current. It does not impact the size of Solar Panels much but it impacts the size of inverter. Although if you go for a high efficiency Inverter AC, then its power consumption will be less and then it would impact size of Solar Panels as well. But if you say go for a BEE 3 star rated inverter AC, then it would need similar size panels as a BEE 5 star non inverter AC. But the size of inverter would be much less in case of inverter AC.

41

Sir 1.5 Ton 5star AC...

42
Abhishek Jain (Mod)

The AC may be rated at about 1450 watts. Assuming right sized AC, it would consume approx 1450x0.75 = 1087 Wh or 1.087 units in 1 hrs. So around 4-5 units in 4 hours.

43

I have recently installed a 5 star 1ton split AC for a room of 90 sqft. And top floor(delhi). I run my AC at 25°c having fan speed in auto mode. My electricity consumption is 6 units for 8 hours. Is it normal for a 5 star rated machine of Bluestar?
Outside temperature is at 35°c .(night)

44
Abhishek Jain (Mod)

Electricity consumption depends a lot on heat load. A typical BEE 5 star rated 1 ton AC would consume about 700-750 units for a usage of 1600 hrs. But this usage is across the year. It will be high in peak summers and low in other seasons. So 4-5 units in 8 hours sounds fine. How did you measure the electricity consumption?

45

By looking at the meter. I note down before and after reading.

46
Abhishek Jain (Mod)

If you are looking at your home meter then there could be more appliances running along with the AC adding to the units.

47

Yeah, I know this. But I stay alone and no other appliances running.
And one thing more I want to know.
I have an energy saving mode( display shows SE while I activate this mode) in my Bluestar AC. But there's nothing in details written about this mode in manual or website. Can you tell me how this machine operates under this mode?
(Fan keeps on running in this mode)

48
Abhishek Jain (Mod)

Energy saving modes work in a few ways: 1) Similar to sleep mode, they increase the temperature setting by a degree or two every hour. 2) They reduce the fan speed 3) At times some ACs just switch off for a few minutes in energy saver mode. You will have to see which one is the case in your AC.

49

I was observing and found that the gap between compressor starts and shuts become frequent in Energy saving mode. I still wonder whether it's less power consuming or not as I don't see any difference. For every 3.44 minutes of Fan operation , compressor runs for the next 6 minutes. That means approx 65-70% compressor running time under a certain temperature. Is it expected?

50
Abhishek Jain (Mod)

Ideal running time for a compressor to give best efficiency is 9 mins. 6 mins is not too bad, but still it should run longer. Decreasing the compressor running time can save electricity. But then the cycle time should not be too short.

51

There's​ an option to Blow air. In which the air only (no cooling) comes out of the AC for 10 minutes after I switch the AC off. It helps the condensor to keep itself clean I guess. Can you tell me how often I should use this option? Is there any problem running it once in a day?

52
Abhishek Jain (Mod)

As a part of regular maintenance, you have to keep the filters clean. You can do that by taking out the filters and clean it as shown in this video: .... Blow Air can clean it for you without the need of taking filters out. Filters should be cleaned once every 5-6 months, else AC will not cool properly and its efficiency will go down.

53

Outdoor temp is 35 and AC set at 25. But I noticed that ODU fan is not rotating after few hours. Is it normal? I meant , while the compressor is off, the FAN in ODU is off. Is there any issue or it's normal?

54
Abhishek Jain (Mod)

Depends on the heat load in the room. If it is less, then compressor/fan may stop..

55

57

As per your AC calculator, I need 1 ton AC. I may have to shift my rented accommodation after 2 years. Should I go for inverter split AC or window ACs with 5 star rating should be preferred?

58
Abhishek Jain (Mod)

Oversizing is not bad in inverter AC (in fact it is good in to oversize in inverter ACs). If you have budget then you may go for 1.5 ton inverter AC. Else you may go for 5 star split AC. Please note, BEE 5 star rated window AC is equivalent to BEE 4 star rated split AC. And you will find that there are hardly BEE 5 star rated window ACs in market.

59

Please Advise : I have a small room on 1st floor 100-Square feet Approx with Asbestos Cement Sheet receiving direct sunlight. Am planning for an A/C please advise the tonnage and which A/c brand I should go. Will Asbestos sheet have a effect on cooling and will it consume more Electricity for cooling in day time. And does A/C works in Asbestos sheet without false Ceiling ? Your advice appreciated.

60
Abhishek Jain (Mod)

I would suggest that you use the calculator on this page to calculate the right size and understand the right star ratings: https://www.bijlibachao.com/top-ten-appliances/best-air-conditioner-ac-window-split-hitachi-lg-carrier-samsung-electricity-consumption-tonnage-in-india.html

Asbestos sheet can actually leave the room too hot and consider adding about 0.2 ton extra to the size that comes out from the calculator. We suggest that use of calculator to get a quick response. If you know tonnage, star rating you want to go for based on your usage and budget, then I can quickly suggest you something. The calculator can help you decide on that.

61

Am planning for 1 ton AC and 5 star rating and does A/C works in Asbestos sheet without false Ceiling ?

62
Abhishek Jain (Mod)

AC can work, but then if the heat load is a lot, you will have to go for a bigger sized AC (slightly more than that what is required). Asbestos sheet can result in a lot of heat and AC will have to work hard.

63
Abhishek Jain (Mod)

Hi Nash,

If you have a single phase connection then the connected load to your house would be quite less for the two ACs. And most likely your wires will also be good enough for less load (connected load). With two ACs it is always better to go for 3 phase connection.

64

Could you please explain why one should not use ceiling fan along with the AC, if the room ceiling directly faces the sun?

65
Abhishek Jain (Mod)

When ceiling directly faces the sun it gets hot and thus the air in contact with the ceiling gets hot. Ceiling fan will throw this air down making the room hotter. And thus the AC will have to work harder to cool the room.

If you do not use ceiling fan in such a scenario then hot air is lighter and cold air is heavier, so the hot air in contact with the ceiling will remain up and will not make the room below hotter.

66

Please, I have a Haier Thermocool Mounted AC. I put it on cool mode and reduced the temperature to 24-degree celsius but it immediately goes to 28/27-degree celsius. I don't Know y. Any help on what to do? Aside from that, the AC is great.

67
Abhishek Jain (Mod)

Would suggest you to contact Haier customer support for the same. They can look at the technical issues.

68

I have hitachi 1.5 ton split ac. It is doing wet in side the room . What should I do

69

YOur AC water outlet is blocked. I always have this problem at home since I dont use the
AC for quite long time. The holes will be clogged by wasps building their nests.Call for annual maintenance if you did not have one this year and get the ducts cleaned.

70
Abhishek Jain (Mod)

Try to get an AC maintenance guy to check your AC. The drainage pipe that goes from indoor unit may have got choked with dust or something. Indoor unit would leak water only if the drainage provided is not proper. Sometime the drainage pipe gets twisted or choked which results in leakage of water inside. The water is basically humidity of the room that condenses on the evaporator coil. And it needs drainage. While installation a regular pipe is put along with copper pipe to drain out the water.

71

GREAT HELP, THANKS VERY MUCH!!

72

The different modes of air conditioner's are awesome and it is really a thing which everyone should understand. Thanks for sharing such a nice topic.

73

If we run the A/C on Fan Mode, does the inside air circulates. I mean does the A/C sucks inside air out and the fan of A/C flows air in?

74

Hi abhishek i have a bluestar 5hw18sbu 1. 5 ton model ac bought very recently. I have several questions. Firstly we do not have a cot so We always sleep on the floor. Whether the ac will be effective in cooling if we sleep on the floor. Secondly i sleep directly under the ac ie close to the wall where ac is fixed. I do not feel the ac air even if the swing is on. Pls advise. Also when the swing is used the air directly falls on the face. So whether it will be wise to keep the swing off keeping the air flow in a fixed position away from us directing towards the ceiling or floor. Whether the air will reach us indirectly. Finally our ceiling directly faces the sun. So in the night is it advisable to use a Ceiling fan or the standing fan. Appreciate ur answers for the above

75
Abhishek Jain (Mod)

You should not use ceiling fan if your ceiling directly faces the sun. Also cooling will certainly reach the floor as cold air is heavier and it tends to move down.

If you want air on you then I would suggest using a table fan or a pedestal fan. That can make it lot more comfortable for you.

76

Sir,

You have suggested not to use the ceiling fan, does this apply both in day and night and also on all types of ACs i.e. inverter and fixed?

77
Abhishek Jain (Mod)

We have in fact suggested to USE ceiling fan if your ceiling does not get direct sunlight. You should NOT use ceiling fan only when your ceiling gets direct sunlight. It is applicable both in day and night. Hot ceiling can heat the air and ceiling fan can push it down increasing the load on the AC. But if the ceiling is not HOT, then use of ceiling fan can certainly help.

This is applicable for both inverter and fixed speed ACs.

78

Dear Abhishek, I have bought the LLYOD 1.5 ton split ac. my room size is 120sqft. but my out door unit is 42feet faraway from indoor unit. is it affect on colling. and which mode we have to use for saving the electricty in LLyod

79
Abhishek Jain (Mod)

42 ft is quite far. A few things are important for right cooling: 1) Ideal Refrigerant pressure 2) Right insulation. When the pipe is long, both these factors can get impacted. You can still maintain the refrigerant pressure by filling in more gas. But insulation is the one which is most impacted. If your pipes are coming from a duct then it is most effective. But if pipes are in open, then the insulation wears off with time. And when insulation wears off, there are heat losses and thus effectiveness of AC goes down.

As for the mode, use cool mode in day time and sleep mode at night. Both should be good to save you electricity.

80
Mohammad Wasim Cheema

Hi Abhishek;

I have an inverter AC of Haier of 18000 Btu. I am also using this with inverter of 3 KW with 200 amps Dry (Deep cycle Batteries). Usually at my place we have 1 hour load shedding after every two to three hour. So i have almost 1.5+ backup. After one hour of operation my AC becomes stable at 2 amps at 27 C which is comfortable for me with lowest fan speed. My question is should i still use the sleep mode to save the power or should i use it in normal mode by setting 27C with lowest fan speed??? And my second question is Monsoon is almost here so should i use Cool mode or dry mode and which will be a power saving mode for me. Awaiting your suggestion. Thank you

81
Abhishek Jain (Mod)

Hi Wasim,

Sleep mode will increase the temperature over the night. So if you start at 27, at night it may go up to 28 or 29 (I mean the temperature setting). If it feels comfortable to you to use it, then using that mode would be more electricity saving. But if at 28-29 it is not very comfortable, then it is better to stick to 27 degrees and low fan speed.

In monsoons the temperature are normally quite comfortable. As long as you are able to remove humidity, it becomes comfortable. So Dry mode would be better than cool mode. The objective in dry mode is to remove humidity. In cool mode the objective is to reduce temperature. The operation of the compressor depends on the objective. If it has to remove humidity, it makes sure that it does that and stops.

One the whole, firstly you have an inverter AC which will save electricity without any doubt. You keep it at 27 which is great and few things here are there would not impact much. Electricity consumption depends a lot on temperature differential between outside temperature and inside temperature. In monsoons that differential is quite less (especially considering that you keep it at 27). A few changes here are there will not create a big impact. But yes if you do want to save a bit, then try sleep mode or dry mode.

82

I have haier ac 1.5 ton its compressor on off cycle is only working on auto mode but its compressor continuously runs on cool mode it doesnt off at any temp set. Ihti

83
Abhishek Jain (Mod)

It should be similar on both the modes at the same temperature settings. What is the temperature setting?

84
pranav anand jha

when AC is in stand by mode than how much power it consumes.

85
Abhishek Jain (Mod)

Standby power is max 5 Watts. Should not be more than that. Then again it depends on AC to AC. Most of them have less than 1 watt standby power consumption.

86

I have a Toshiba ac 1.5 ton split ac RAS18SKPX,,is this consumes less energy at auto mode.

87
Rudraksha Bhattacharyya

I have an carrier inverter split ac. when i put my ac on sleep mode at morning it turns off automatically. Is this normal?

88
Abhishek Jain (Mod)

I am not sure if carrier has given such feature in the AC.

89
Grace Mallileur

sir, i have an ac of hitachi. it has the auto clean option. i referred the manual , it says that the auto clean works only while in standby mode. can u please explain what is this standby mode and how to keep the ac in this mode?

90
Abhishek Jain (Mod)

Standby mode is when the AC is on from the plug point but is not in use. When the AC is in use the filter is in use and thus cannot be cleaned. It can be cleaned only when AC is not in use.

91

I am using sharp J-tech inverter ac. I have a baby of 1.5yr. Now let me know the best power savings mode for us.

92
Abhishek Jain (Mod)

Use in cool mode during the day and sleep mode at night. It should be good. Also try to keep the temperature as high as possible. Anything 25 and above would be energy saving.

93

The right side of my AC blows more air than the left and middle part. Is that normal? I can vertically adjust the air flow. The slot through which the air flows from the indoor unit is divided into 3 parts; left, right and middle and I have the left side calibrated towards a different direction than mine and the air from the middle and the left part in adjusted in a way so as to keep the flow in my direction. Mine is a Toshiba inverter AC.

Hi Shubham,

I am not sure if you have put this comment in continuation of an existing discussion or is it a new discussion on this site altogether. By the way all the sides should blow air equally well, so what you observed is not normal.

Samsung inverter ac has option for auto and cool mode at 25 deg which would be the best mode for comfort and electricity saving option Rajasthan outer temperature 34 to 38 deg night

Hi, Abhisekh, I have 1.5 Ton godrej Split AC, how's it use for more power consumption and how much consumed electricity in continue 4 hours running .
And also please tell me about auto mode.
And which mode is more useful for power consumption.

98
Abhishek Jain (Mod)

Cool mode would be better.

99

I have a inverter ac 1 ton like to know the best mode options for termal comfort and save my expenses on my electric bill.

Use it either in cool mode (during the day) and sleep mode (at night).

101

Sir, I have Lloyd Split ac
Please suggest how set auto Temp. adjust mode.
Model: LS19A3LX

102

Sir,
I have a videocon split ac bought about 5 years ago.

On the left hand side of the remote options are- Auto, Cool, Dry, Heat, Fan
On the right hand side of the remote options- Sleep, Lamp, Turbo, Clean, Hold

It would be helpful if you could explain me the 3 options on RHS- Lamp, Clean and Hold

103

Lamp is to turn led light on/off on ac.
Clean is for cleaning ac filter.

Hi Sukanya,

I am sorry, I do not have any idea on Lamp, Clean and Hold on the remote control.

105

I just got a Panasonic Inverter 12000 BTU , but the manual does state clear how to activate ECONAVI . So based on your recommendation i placed it at 25c , settings cool... fan speeed and air swing auto. Do you have any experience with these models? I am assuming cool mode is the ECONAVI mode though

106

NEVER go for Panasonic AC. Quality control is very bad. I had purchased a 1.5 T Panasonic inverter AC. During installation it was found that blower in the indoor unit was broken. After Many mails, phone calls and emails they ultimately replaced the blower after one month. after changing the blower when they started the AC the fan of the ourdoor unit was not working, however the service engineer repaired it and started the machine. Again after 20 days the machine sopped cooling and service engineer found gas leakage. still I am waiting for last one week for the service engineer to fix the problem. panasonic is the worst AC I have come across.

107

mhm I haven't had any of those problems, have it for 4 months now .. I got this from a dealer in my country which is covered by warranty once I let their electrician install , so I should be good

Hi Sheldon,

I am sorry, I do not have any experience with Econavi technology. So can't suggest on how to activate it.

109

I see Auto, Cool and Dry... is either between Auto and Cool but not sure.... I set the fan speed to auto and air swing to auto

110

Auto mode is similar to Cool mode. In Auto mode, the AC will try to cool the room faster and then will adjust the temperature to desired settings. In cool mode, the AC will not try to cool it fast but will go at its own pace. In Dry mode, the objective of the AC is to remove maximum humidity, and once that is done, it will come back to the set temperature.

Thanks for summing it up

112

Thanks

Hi All, I purchased voltas 1.2 ton AC last week... I have set the temperature to 25 degree but even after 1.5 hour the room temperature showing in the indoor unit is 27 degree But inside the room feels more colder than 27 degree and after few hours the temperature on IDU reduced to 25 degree but it feels much more colder inside room... Is there a problem in thermostat or its showing wrong temperature. Please advice.

114

Did you check the room temperature using a thermometer? Typically AC thermostat measures grill temperature or the temperature close to the indoor unit of the AC.

I hope you are not comparing temperatures based on the experience of your previous air conditioner. Old ACs tend to be less efficient.

115

Thanks Abhishek, I have checked the room temperature with a thermometer and its showing a low temperature. I'm staying on top floor so I think the IDU is measuring temperature close to the roof and that's why its showing a higher temperature.

116

Ideally, the grill temperature is colder than the room temperature. Your situation is very strange. I think that the thermostat is not working properly. You must get it checked by Voltas.

117

I purchased an Bluestar AC with 3.80EER...How is it....Will it save a good amount of Electricity??? I am yet to get my first electricity bill after installing AC....If i set temp. at 21 degree...will it consume very much electricity???

118
Abhishek Jain (Mod)

Which model have you purchased? Because I am not aware of any Blue Star model with EER of 3.8!! Blue Star non inverter models are not that efficient! By the way, 21 is too cool and keeping AC at that temperature will certainly result in high electricity bills.

119

Also wanna know what do the temp button in my remote does...there are 3 symbols 1. A home and a thermometer inside,2. A Home and thermometer outside. 3. a Home 4. the symbol vanishes....There is nothing written in the manual about this....what does this symbols means and which symbol should i opt during my use..??? Please help me.

I guess you have a model with iFeel technology from Blue Star. Typically air conditioner thermostats measure grill temperature and work according to that. From grill temperature I mean, temperature of air that is extremely close to the indoor unit. But the temperature of air in the room is not the same. In fact room temperature varies depending on the spread of cool air.

Blue Star iFeel technology has thermostat in the remote control itself. So if you keep the remote with you, then it will sense the temperature of that part of the room where you are located and will try to work based on that.

I am not very sure, but my guess is that options you are talking about lets you choose which thermostat do you want to use: one in remote or the one in indoor unit that measures grill temperature.

121

Hello all, is there any gadget or device available to check humidity and temperature of the room...if yes..thn what is it called??? I think my AC isnt working properly...wanna check before calling the technician..

Simple one like this will also be usefull : http://www.amazon.in/gp/product/B00RHH5HHA/ref=as_li_tl?ie=UTF8&camp=3626&creative=24822&creativeASIN=B00RHH5HHA&linkCode=as2&tag=bijlbach-21

But please note: room temperature is different from grill temperature. The AC themostat measures temperature at the grill or temperature which is extremely close to the AC. If you keep the thermometer far away from AC, then it will not be the same as grill temperature. In fact temperature will vary across the room based on the spread of cool air.
