In these days, saving is as important as earning..
Here are some tips to lower your AC consumption:-
1) Setting Temperature to 25/26 °C :- The most efficient temperature for running an AC is 25.5 °C. Keeping set temperature in 25/26 °C range will lower energy consumption significantly.
2) Using ceiling fan along with AC :- Using ceiling fan with AC will help air circulation and will give you chill feel even at 25/26 °C setting range. Also, your fan uses far less power than your AC. So by using ceiling fan, you will end up saving some more units. (Avoid this if you live at topmost floor or your ceiling is subjected to direct sunlight over it. Although you can use it if there is any kind of shade from solar system or water tank over that room)
3) Restrict sunlight in the room :- Try to cover up areas to avoid sunlight penetration in the room. This will help in keeping room cool.
4) Keep Doors and Windows closed :- Keep Doors and Windows closed and avoid using them frequently.
5) Covering Gaps :- Try covering gaps in Windows and gap below Doors as cool air settles below and gets out from those gaps.
6) Turn off Ac at night :- Try setting Auto Turn off mode or Sleep mode in AC to turn off AC when ambient temperature is low especially after midnight.
7) Clean AC indoor-outdoor coil regularly :- Try cleaning AC indoor-outdoor evaporator coil regularly with blower. Do this only if you have proper knowledge about the AC. Do this only if outdoor is safely accessible. (With proper knowhow, you can do wet cleaning too)
Bonus Tip :- If you find that the copper line or indoor is frosting frequently (Getting White Frost or Ice) even at normal set temperature, get the AC gas checked from technician. If it is low, consumption would be high and will deteriorate your AC compressor.
This is from my personal experience, study and professional experience as Facility Engineer.
I hope this will bring some savings at your end.

i have put a thick layer of paper on the roof & put some stones to keep it intact from winds. this way the room is a lot cooler & i am not using AC most of the days. just using fan.
24°C
Yes, i was searching for 24 degree celsius 
My findings.
22°C – 24°C = avg bill 2500-3500
26°C = avg bill 1000-1200 with ceiling fan on at low speed
That’s huge difference….had seen one youtube video on this and since than I am using this technique
Edit – usage time: 6-10 hours daily
which city and type of ac – split or window
I have inverter ac of Voltas I keep temp at 26-27 daily. I have terrace on above me and I get direct sunlight after 2-3 pm daily . But Inverter ac keep room temperature and keep temperature automatically lower when room temperature becomes low right ?
You all are talking about 24-26° and here i keep 30° with fan at middle level.
As per studies saying the lower the temperature, higher the sleep quality. It depends on peoples body type. Some feels good at 26, some at 22. More over AC consumption should be on need basis. so slight increase in cost ok with satisfaction. If you top floor use table fan instead of ceiling fan. but I prefer without fan at 26 and without bedsheet.
in my case, we have 2 Split, (1t & 1.5t), in one room we keep 24 degrees, usage – 6hrs per day. another 27 degrees, usage – 10hrs per day. we have Fridge and other home items as usual. We get per month about 1300-1600/- monthly.
Considering 2 ac u have low and proper bill. Are u from MSEB user?
Gonna be all personal and stuff, so let me be a gentleman first, a nice dinner. 
My comfort is at 19°C. I am sure that a lot of people are too, but I sleep the same way I came to this world at that temperature. I sleep above the comforter and just a cotton sheet to cover me. If I put on clothes or sleep under the comforter, my bed could solve the water crisis.
During winter, when I go outside, summer styles till 10°C, 4-10°C just a t-shirt under the dress shirt. I only resort to jackets only at temperature below 4. So you can imagine the summers when I had to wear a suit.
Long story short, I am HOT 
5th point is not required!
Let some air flow through the gaps of doors and windows. If not, then the environment inside the room can become breeding grounds of fungi and bacteria! (Not noticeable generally, since people don’t use AC 24/7).
……… Issued in public interest 😛……….
Yes, Fresh air is must. Not recommended during lockdown period. 
If I am comfortable at 26°C setting alone, why to use ceiling fan extra? Am I missing something?
Not that necessary. But it is good to study as Cool air settles at lower level. Air circulation helps in keeping room uniformly cool and gives you perfect cool feel. If you are good at 26℃ without fan, you can try setting 27℃ with fan.
Just 1℃ difference in set temperature translates into decent savings. It is good to try and figure out the best option for you, at your setup itself, as there are many factors affecting cooling and thereby, the consumption.
Apply Lime + Fevicol DLL on the roof
wish i had read this a few days back. my room is subject to direct sunlight and above my room is open terrace. Im not that comfortable in AC. I feel fastened in it. Im thinking to go for a cooler. But will surely try this today
@Dhanu10892 Are you sure about point 2? because using room fan actually increased the room temperature so AC needs to extra power to maintain the temperature.
See the main reason behind using a ceiling fan is that it circulates air.
1) Main power consumer in AC is outdoor Compressor and Outdoor Fan. Compressor cuts off (Turns Off) once sensor in AC indoor suction end senses the set temperature at or below set point.
As cool air settles down and warm air gets lifted up, sensor will not sense the desired temperature and keep compressor on until it reaches that point. Once sensor senses setpoint temperature, temperature at lower level in room is far less than set temperature.
That is why most people keep AC at 20-22 as they don’t get the feel.
Fan regulates air and facilitates sensor to sense true average room temperature, which in turn keeps room uniformly cool and cuts off compressor sooner each time.
2) Secondly, Fan provides air breeze which gives chilling feel even at 25-26 temperature. Means it gives comfort at higher set temperature. Fan uses far less energy than your AC outdoor.

Using ceiling fan along with AC only advised if your ceiling is not getting direct sunlight. If you are living in top floor, using the fan will make the AC work longer. But it’s okay if your roof has some setup to reflect heat.
