Air conditioners have become an essential part of modern life, providing us with comfort and relief from sweltering heat. However, with great comfort comes a cost, and one of the primary concerns when it comes to air conditioners is their power consumption. Understanding how much electricity your AC unit uses can help you make informed decisions about energy efficiency and cost savings. In this blog post, we'll delve into the factors that influence the power consumption of an air conditioner and provide tips on how to manage it effectively
Let me clarify that the energy consumption of an air conditioner depends on various factors, such as its technology, ratings, capacity, location, and type (whether it's a window or split unit).
An air conditioner can use anywhere from 1800 to 7000 watts, depending on its capacity. A typical domestic air conditioner consumes approximately 500 to 3000 watts and can use between 1500 to 8000 kWh annually when operating for 7 to 8 hours per day.
1. Understanding the Basics
Before we dive into power consumption specifics, it's important to grasp the fundamental concepts related to air conditioning units:
2. Factors Influencing Power Consumption
Several factors can affect the power consumption of an air conditioner:
3. Calculating Power Consumption
To estimate your air conditioner's power consumption, you can use this formula:
Power Consumption (in watts) = BTU / SEER
For example, if you have a 12,000 BTU air conditioner with a SEER rating of 15, the power consumption would be:
Power Consumption (in watts) = 12,000 BTU / 15 SEER = 800 watts
Keep in mind that this is just an estimate. The actual power consumption can vary depending on factors like the temperature setting and how often the unit cycles on and off.
4. Tips for Managing Power Consumption
Now that you have a better understanding of the factors at play, here are some tips to manage your air conditioner's power consumption effectively:
If you have a 1.5 ton AC in your house and operate an average of 8 hours a day, a 1-star rating AC consumes more than 9 kWh.
On the other hand, if AC is of 5-star rating, then it will consume about 7 Kwh.That means saving about 2 Kwh every day. In such a situation, if the old AC is replaced with 5 star AC, we can save more than 700 Kwh in a year.If we consider electricity cost 12 cents per kilowatt-hour, then we can save $84 annually.
In simple words, we can understand as below
How to calculate air conditioner electricity use? - in Watts, Cost & kWh
Let's take an example
Your Air Conditioner wattage(as you can see in above image) = 800 Watts
Estimated Usage Per Day = 8 hours per day
Total energy Consumption in one day = 800 x 8h = 6400Wh/1000 = 6.04kWh/day
Monthly Cost of your Air Conditioner= 6.04kWh/day x 30 days x $0.12/kWh = $21.74/month
Yearly Cost of your Air Conditioner= 6.04kWh/day x 365 days x $0.12/kWh = $264.55/year
To summarize the above calculation, we have:
Air Conditioner Wattage x Hours Used Per Day = Watt-hours per day
Watt-hours / 1000 = kWh per day
kWh per day*30* one unit price of electricity(you can find in your electricity Bill)=Monthly Cost

Reduce electricity bill by 30 percent by running AC at 27 degrees
If we operate the AC at the right temperature, then we can save money with electricity.
According to energy experts, if we run AC at 27D, then we an also reduce the our electricity bill by 20-30 percent in a year.
we believe that the room cools quickly if we set the AC temperature to 18 degrees. But let me tell you are wrong that if also thinking the same. set the temperature to 18D OR 26D degrees it will cool the room at the same time.
Note: This estimated figure will depend on room size, temperature, and city.

Ajay Mathur (Director General, Terry) said - "Even if it is very humid, the temperature of AC is comfortable at 24 degrees. It also saves energy and money compared to 18 or 22 degrees."
If you are thinking of buying an air conditioner (AC), then you should know about some important things about AC such as which AC you should take, SPLIT AC or WINDOW AC.
What does the star rating of an air conditioner mean, what does ton mean in AC like what is the difference between air conditioners of 1 ton, 1.5 ton and 2 ton and what is an inverter air conditioner?
Let me clarify your query one by one.
Air conditioners are mainly of 2 types.
Window A / C - As its name is "Window", it clearly states that this type of air conditioners are installed on the window of the home or offices.
You must have seen such A / C on the windows of many houses with a part of it is outside the house with the help of the window and the cooling part is inside the house.
Split AC-Split AC has two units: Out-door and In-door.The in-door part is kept indoors(inside room) and Outdoors can be placed outside the house or on the roof because the outdoor unit needs fresh air.A pipeline connects the Indoor and Outdoor units.
What does 1 ton, 1.5 ton and 2 ton AC mean? What is Ton in AC?
Whenever someone goes to buy AC, they are asked how much ton of AC they need, then that person thinks about what ton means and many people understand that ton means air conditioner Weight.
Let me tell you that ton does not mean the weight of the air conditioner (AC).
Ton means the cooling capacity of AC, In simple words, you can say "how much heat an air conditioner can reduce in an hour", and this amount of heat is measured in BTU (British Thermal Unit).
An air conditioner needs about 20 BTU per hour to cool a square foot space and 3.5 BTU is equal to 1 watt so 1 ton is equal to 12000 BTU.
Understanding the power consumption of your air conditioner is crucial for managing energy costs and reducing your carbon footprint. By selecting the right AC unit, optimizing settings, and maintaining your system, you can strike a balance between comfort and energy efficiency, ensuring that your cooling needs are met without breaking the bank. Stay cool and energy-wise!
