Many people wonder if keeping their air conditioner on wastes electricity. The answer is yes, keeping the air conditioner on does waste electricity. This is because, even when the air conditioner is switched off using a remote, it continues to consume electricity until the plug point is switched off. This phenomenon is known as 'vampire power', where appliances continue to consume a significant amount of power when they are on standby mode. To save electricity, it is recommended to switch off appliances from the plug point when they are not in use.

What You'll Learn
Servicing your AC can help save electricity
Air conditioners consume a lot of electricity, costing homeowners billions of dollars annually. While modern ACs are designed to consume less energy than older models, they still contribute to high electricity bills.
Secondly, scheduling professional maintenance can keep your AC in top shape and improve its energy efficiency. Over time, AC components can experience wear and tear, reducing the system's overall efficiency. Professional technicians can inspect, clean, and optimize the entire AC system, ensuring it operates at its energy-efficient best.
Thirdly, servicing your AC allows you to address any issues with insulation and physical factors in your environment that may impact its performance. For instance, shading windows, investing in insulation, and considering humidity levels can all help reduce the workload on your AC and, consequently, save electricity.
Additionally, it is always a good idea to service your AC before extended usage, such as during the summer months. By doing so, you can ensure that dust or other particles have not accumulated within the machine, which could otherwise hinder its performance and increase electricity consumption.
Finally, remember to turn off your AC at the power switch when not in use. While this is not directly related to servicing, it is a crucial step in saving electricity. Many people make the mistake of turning off the AC with a remote, leaving it on standby mode, or idling, which wastes electricity and affects your monthly bill.

Switching off at the plug point saves electricity
Switching off appliances at the plug point is an effective way to save electricity. Even when appliances are turned off using a remote control or power button, they can still consume electricity if they are not unplugged. This is known as 'vampire power', where appliances continue to draw power when on standby mode or when their main switches are not switched off.
A survey by the Citizen Consumer and Civic Action Group found that over 70% of respondents ran their appliances on standby mode, leading to unnecessary expenditure on electricity. Vampire power can add about 1,000 to electricity bills annually and translates into 174 units of vampire loss. This wasted energy is evident when touching a mobile charger, voltage stabilizer, or set-top box, as these devices emit heat energy even when not in use.
To reduce vampire power, it is recommended to develop the habit of unplugging appliances when they are not in use. For those who find it inconvenient to unplug multiple devices, a power strip can be used to control several appliances simultaneously. Smart power strips, available in various developed countries, automatically disconnect appliances from the mains when they enter sleep mode.
Additionally, it is worth noting that modern air conditioners are designed to consume less energy than older models. However, running an AC continuously can still result in high electricity bills. To save electricity and reduce costs, it is advisable to turn off the AC when it is not in use and use the timer feature to set a specific duration for cooling. Servicing your AC regularly and ensuring the room is properly sealed before turning it on can also help optimize its efficiency and reduce electricity usage.

Using a timer is better than running AC all night
Keeping the AC running all night can lead to a high electricity bill at the end of the month. While modern ACs are designed to consume less energy than older models, they still contribute significantly to monthly electricity bills.
Using a timer is a better option than running your AC all night. All ACs come with a timer, so it is better to use this feature instead of running the machine all night. Setting the timer for 2-3 hours before bedtime is a good idea. This will reduce overusing the air conditioner and also cut down on electricity bills.
Another way to save electricity is to ensure that the AC is switched off at the power switch, not just the remote. When an AC is switched off using the remote, a lot of electricity is wasted when the compressor is set to 'idle load', which also affects your bill.
Additionally, it is a good idea to get your AC serviced regularly, especially if it is not used throughout the year, as dust and other particles may damage the machine. Servicing your AC can help to improve its efficiency and save you money in the long run.
By following these simple tips, you can reduce your AC electricity bill and also prolong the life of your air conditioner.

Running AC at 27°C vs 18°C can cut bills by 30%
Keeping an air conditioner on can waste electricity in multiple ways. Firstly, if the AC is switched off using a remote, but the main power switch is still on, it will continue to consume power, a phenomenon known as 'vampire power'. This can add significant costs to electricity bills, with a survey by the Citizen Consumer and Civic Action Group finding that this can result in an additional spend of about 1,000 rupees on electricity bills annually.
To save electricity and reduce bills, it is recommended to always turn off the power switch when the air conditioner is not in use. Instead of running the AC all night, use the timer feature to set it for 2-3 hours before going to bed. This will prevent overuse of the AC and reduce electricity bills. Additionally, servicing the AC regularly and ensuring all openings in the room are shut before turning it on can also help to save electricity and cut bills.
Now, to address the specific scenario of running the AC at 27°C vs 18°C. While there is no definitive answer to the exact savings, it is safe to assume that running the AC at a higher temperature will result in reduced electricity consumption and lower bills. This is because the compressor, which is responsible for cooling the air, will not have to work as hard to maintain a higher temperature. As a result, it is reasonable to expect a reduction in electricity bills when comparing running the AC at 27°C to 18°C. The exact savings will depend on various factors, including the efficiency of the AC unit, the size of the room, and the duration of usage.
To maximize savings, it is recommended to follow the previous advice of servicing the AC regularly, ensuring all openings in the room are shut, and using the timer feature instead of leaving the AC on all night. These practices, combined with running the AC at a higher temperature like 27°C, can significantly cut electricity bills, potentially by up to 30% or more. The exact savings will depend on the specific circumstances and usage patterns, but it is clear that making these adjustments can lead to noticeable reductions in electricity consumption and costs.

Vampire power — AC on standby mode wastes electricity
Keeping your air conditioner on standby mode wastes electricity, a phenomenon known as 'vampire power'. Vampire power refers to the electricity consumed by appliances that are on standby or those whose main power switches are not switched off. A survey conducted in seven districts found that more than 70% of respondents ran their appliances, including air conditioners, on standby mode round the clock, incurring expenditure for electricity that was not used.
Consumer activists and officials say that end-use electrical equipment consumes power when on standby. For example, television sets and air conditioners that are remotely switched off, music systems on standby, and mobile phone chargers that are plugged in continue to consume a significant amount of power. This results in an additional annual spend of about 1,000 on electricity bills, according to a survey by Citizen Consumer and Civic Action Group. This translates to 174 units of vampire loss, which could otherwise run a five-star-rated 1.5-ton air conditioner for 116 hours.
To reduce electricity wastage, it is recommended to always turn off the power switch when the air conditioner is not in use. Using a timer is also a good idea instead of running the machine all night. Setting the timer for 2-3 hours before going to bed will reduce overuse of the air conditioner and cut down on electricity bills.
Other ways to save energy include weatherizing your home with basic air sealing and insulation, and setting your water heater to the right temperature.
