ACs may be found everywhere, starting from ordinary households to the fast-paced environment of the workplace and commercial organizations.

In addition, they offer instantaneous comfort and cooling to battle the physical impacts of hot weather. As AC units serve to be a crucial electrical appliance almost all around the world, it is intended at providing the users with the greatest possible experience by including a variety of useful modes or features. In the previous ten years, technology has grown significantly, and new ACs come with far more complex functions than the old window rattlers.

These Air conditioners contain a lot of functions that you probably aren’t aware of. The majority of consumers merely want to set their thermostats to a specific room temperature. However, they may be missing out on some innovative features that would help them save energy without compromising on their comfort.

The latest and the best window and split air conditioners have a feature known as Sleep Mode in AC. This does not necessarily imply that you should only use it at night when you are sleeping. In fact, after each hour of operation, AC Sleep Mode raises the thermostat’s temperature by 0.5-1 degrees. This adjustment range is capped at a temperature increase of 2 or 3 degrees based on different brands and models, and it can allow you to save quite a great deal on your electricity bills. Because our bodies require less cooling once we’ve fallen asleep, this setting is intended to be utilized at night. 

As we’re unable to change the target temperature while we’re asleep, we end up wasting a lot of money with every hour the AC tries to keep up this low-temperature value the entire night. But thankfully, these modern-day smart ACs can now automatically increase the temperature setting for saving energy without affecting our comfort or waking us up by employing this sleep function in ac.

How Does Sleep Mode Work?

Our bodies can quickly cool down, but warming up is more difficult. We don’t need as much cooling once we’ve fallen asleep. When you enable this option, the unit will automatically regulate the air you breathe while you sleep by increasing the temperature by 0.5 to 1 degree every hour

This may go up to a maximum temperature of +3 degrees, which is still plenty to keep you comfortable and comfortable during the night. Sleep mode along with dry mode is found on almost every air conditioner. Simply turn on the feature using the control panel or the air conditioner’s remote controller.

You may also expect your sleep mode to operate even better if your air conditioner includes a built-in sophisticated movement sensor (comes with all the higher-end brands and variants). These sensors can identify whether you are sleeping quietly and still, allowing the machine to send signals to boost or reduce the cooling temperature. This user-friendly function only improves your sleeping cycle, resulting in healthier sleep habits.

Benefits Of Using Sleep Mode

1. Maintains The Sleep Temperature For Efficient Energy Usage And Maximum Comfort

One of the most common questions that people come up with is- “does sleep mode in ac save electricity?” So, let me tell you, as the AC reduces its capacity when operating on the sleep mode, it uses less energy and power, thereby saving you a fortune on electricity bills.

AC sleep mode also adds to your comfort by assisting the AC in increasing the temperature each hour, allowing you to adjust as your body warms up easily. Given that an increasing number of people are struggling to make ends meet before the end of the month, such opportunities to reduce your monthly expenditures are more than welcome. The best part about sleep mode in ac is that it lets you maintain your preferred sleeping temperature.

2. Wake Up To A Controlled And Comfortable Temperature Every Day

If you’re like most people, you often wake up early in the morning, cold and in need of a bigger blanket. This is a frequent thing that happens to the majority of people. You won’t feel cold in the morning as you approach your wake-up time if your air temperature increases automatically every hour. 

As the sleep function in ac allows your AC to readjust the temperature every hour, you may wake up to a temperature that is neither too chilly nor too hot. You’ll get a night of better sleep, wake up rejuvenated and ready to face the difficulties of the day ahead. Moreover, you’ll save money along the way.

3. Advantageous For People Who Are Sensitive To Temperature Changes

If you are someone who gets affected or who is sensitive to even the slightest of temperature changes, the Sleep Mode in AC coupled with an intelligent movement sensor can detect your every move, sleeping disturbances, and in turn, prove to be beneficial. Motion detecting sensors are fitted into some modern air conditioner units to assist you in getting a night of better sleep. 

These sensors can identify whether you’re sleeping soundly or not, allowing the temperature to be adjusted accordingly. The AC unit will track your sleeping patterns and alter the room temperature accordingly to optimize your sleeping patterns. You’ll feel terrific and well-rested when you wake up in the morning.


So, that was all about the sleep function in AC. It depends on you and your requirements if you want it or not. In case your AC already contains this feature, give it some time to figure out how to operate sleep mode in AC and how well it works for you. If you’re in the market for a new AC unit, you need to get equipped with some prior info to see if such sophisticated features are right for you and your family. Also, ensure that they are within your budget, as current technology is not inexpensive. Because the best air conditioners are also the most expensive, you must make sure you can afford them.


The AC sleep mode is relatively easy to activate on most air conditioner models. It can be done by simply pushing a designated button on the remote control. Some types allow you to control the rate at which the temperature rises, while others have a default setting that you can’t change.

If you want additional flexibility, make sure to discuss it with the dealer before purchasing your air conditioner. Take the time to examine this feature across several brands and models so that you can make the best purchasing decision possible. The time you spend researching will be well worth it because you will be happier with your purchase.

Sleep mode gradually raises the thermostat temperature by one degree every hour until it reaches a maximum of two degrees. If you prefer to sleep at low temperatures, this will help you save electricity because every degree of temperature increase saves electricity. It is preferable to utilise cool mode or energy conservation mode at 25 degrees if thermal comfort is your sole concern.

The timer enables you to choose when to turn off the air conditioner by repeatedly pushing the timer. In contrast, AC sleep mode lets you control when to turn off the air conditioner by repeatedly pressing the sleep button.
