20 Tips on How to Save Huge Electricity Bill in AC

As summer comes in India, every one gets these two big worries: how to stay cool in the heat and how to deal with the high electricity bills from using AC and many houses in India have more than one AC, and they run for several hours to beat the heat. According to the India Meteorological Department (IMD), 2024 will be a sweltering summer with more heat wave days than usual.

Although new age, modern ACs are designed to use less energy, but with temperatures rising day buy day and people working from home more, ACs are running longer, which means higher bills. 

Reducing AC bills is not only good for your wallet but also helps the environment by using less energy. So, it’s important to find ways to spend less on electricity while staying cool.

If you have more than one AC at home, it’s even more important to save electricity. Otherwise, you’ll end up with a huge bill. Even if you have a window AC, finding ways to lower your bill is key to avoiding sleepless nights worrying about your expenses.

Here are the best and reliable tips to reduce AC bill:

1. Turn off the AC when you’re out:

This might seem like a no-brainer, but it’s a surprisingly common culprit for wasted energy. Many people keep their AC on when they go out and think their room will be chilled when they will be back home. Develop the habit of switching off the AC before you head out, and enjoy the satisfaction of returning to a pre-cooled haven upon your arrival.

2. Finding the Sweet Spot: Always keep it on the perfect temperature:

There’s a misconception in many people that keeping the AC down to the lowest temperature is the fastest way to cool a room. However, this method not only wastes energy but can also lead to discomfort and higher electricity bills. Instead, aim for a comfortable setting between 24°C (75°F) and 26°C (79°F). Each degree lower can significantly increase your energy consumption.

3. Banishing the Hot Air: Sealing Those Windows:

Windows and doors are the main entry points for unwanted hot air. Invest in weather stripping or caulking to seal any gaps around windows and doors, preventing precious cool air from escaping and hot air from sneaking in.

4. Use AC and Fan Together

Ceiling fans circulate the cool air from your AC more effectively, allowing you to raise the thermostat setting slightly without compromising comfort. This dynamic duo can significantly reduce your AC’s workload and, subsequently, your energy consumption.

5. Regular Maintenance: Keeping Your AC in Top Shape

Just like a car needs regular servicing to run smoothly, so too does your AC. Neglected air filters become clogged with dust and allergens, forcing your AC to work harder to maintain the desired temperature. Schedule regular cleaning or replacement of air filters as recommended by the manufacturer. Also, consider professional maintenance every year to ensure proper cleaning of coils and fins, maximizing efficiency.

For the truly dedicated energy crusaders, here are some additional maintenance steps you can consider:

6. Clean or Replace Air Filters:

As mentioned earlier, clean air filters are crucial for optimal AC performance. Check your manufacturer’s recommended cleaning or replacement schedule and stick to it.

7. Check and Clean Coils and Fins: 

Over time, the condenser and evaporator coils in your AC can accumulate dirt and debris, hindering heat transfer. A professional cleaning service can remove these contaminants and restore optimal performance.

8. Inspect Ductwork and Seal Leaks: 

Leaky ducts can significantly impact your AC’s efficiency. Have a qualified technician inspect your ductwork for leaks and seal any identified ones to prevent cool air from escaping before it reaches your desired space.

9 . Proper Thermostat Placement: 

Where you place your thermostat significantly impacts your AC’s efficiency. Avoid placing it near heat sources like vents, windows, or lamps, as this can lead to inaccurate readings and cause your AC to work harder than necessary. An ideal location would be on an interior wall, away from direct sunlight or drafts.

10. Use Sleep Mode and Timers:

Gone are the days when your AC had to hum a lullaby all night. Many modern ACs boast a sleep mode or timer function. This allows you to program the AC to automatically adjust the temperature slightly upwards as you drift off to sleep. Since you’ll likely be snuggled under a blanket, a few extra degrees won’t be noticeable. Then, the AC can automatically adjust back down to your preferred cool setting before you wake up. This clever automation ensures a comfortable night’s sleep while minimizing energy consumption.

11. Invest in Inverter AC:

Traditional ACs operate like on-off switches, cycling at full power to reach the desired temperature and then shutting down completely. This constant stop-and-start action can be inefficient. Inverter ACs, on the other hand, are game-changers. They utilize variable speed technology, constantly adjusting their power output to maintain the set temperature. This smoother operation translates to significant energy savings compared to traditional models. While the initial cost of an inverter AC might be slightly higher, the long-term savings on your electricity bills make it a worthwhile investment.

12. Smart Cooling: The Future is Here:

Technology is on your side when it comes to AC efficiency. Smart ACs integrate Wi-Fi connectivity, allowing you to control them remotely using a smartphone app. Imagine the convenience of pre-cooling your home from the office on a scorching day or adjusting the temperature while relaxing on the couch. But the real benefit lies in their ability to learn your routines and preferences. Smart ACs can optimize cooling schedules, suggesting adjustments based on weather conditions and occupancy. This level of control empowers you to achieve peak comfort with minimal energy use.

13. Shading Your AC Unit and Windows

Your AC works best when it doesn’t have to battle the relentless heat radiating from your outdoor unit or streaming through sun-drenched windows. Here’s a two-pronged approach:

  • Shade Your AC Unit: The brutal afternoon sun can significantly increase the workload on your outdoor unit. Consider installing an awning or planting shade-giving trees or shrubs around the unit. This simple step keeps the unit cooler, allowing it to function more efficiently.
  • Block the Sun’s Heat: Similarly, south-facing windows are prime targets for solar heat gain. Invest in curtains, blinds, or even reflective window film to block the sun’s rays from penetrating your home. This reduces the amount of heat your AC needs to combat, keeping your cool haven comfortable without overexerting your AC.

14. Correct Installation Matters:


The foundation of efficient AC usage starts with proper installation. An incorrectly installed AC can lead to a a lot of problems, including reduced cooling capacity and higher energy consumption. Ensure a qualified technician installs your AC unit, following manufacturer guidelines and ensuring optimal airflow and performance.

 15. Insulation and Avoiding Direct Sunlight

Just like a well-insulated thermos keeps your drink cold, proper insulation in your home keeps the cool air in and the hot air out. Consider insulating your attic, walls, and even windows to minimize heat transfer. Additionally, minimize the use of heat-generating appliances like ovens or dryers during peak sun hours. This reduces the overall heat load within your home, making it easier for your AC to maintain the desired cool temperature.


16. Power Fluctuations:

Voltage fluctuations are a common occurrence in India. Consider using a voltage stabilizer specifically designed for ACs to protect your unit from damage and ensure consistent performance.

17. Continuous Use vs. Strategic Cooling

A common misconception is that leaving your AC running constantly is more efficient than switching it on and off frequently. This isn’t the case! Modern ACs are designed to reach the desired temperature quickly and efficiently. When you leave the AC running continuously, it might cycle on and off at lower power settings, which can actually be less efficient than letting the temperature rise slightly and then allowing the AC to cool the space down again in a single cycle.

18. Selecting an Energy-Efficient AC:

When purchasing a new AC, consider the star rating system from the best AC brand, which indicates energy efficiency. A higher star rating signifies lower energy consumption. While a 5-star AC might be ideal, a 3-star AC can also be a good option, offering a balance between efficiency and affordability. Additionally, look for models with features like inverter technology and eco-modes for further energy savings.

19. Shutting Off Other Electronics:

While your AC might be the main energy culprit, don’t forget about other electronics. Standby power, also known as phantom power, refers to the small amount of energy electronic devices continue to draw even when switched off but still plugged in. Eliminate this hidden energy drain by unplugging electronics like chargers, TVs, and game consoles when not in use. Power strips with on/off switches can also be helpful in managing standby power.

20. Embrace the Power of Plants

Houseplants not only add a touch of life to your décor, but they can also contribute to a cooler environment. Plants absorb heat and release moisture through transpiration, creating a slightly cooler microclimate around them. Strategically placing plants near windows or heat sources can provide a natural cooling boost

Bonus Tips: 

  1. Consider Humidity Levels:

Maintain humidity between 20% to 80%, with a lower range of below 60% RH in high humidity areas, to optimize AC efficiency and energy savings.


2. Mind Your Furniture Layout: 


Avoid placing large furniture items near air vents and refrain from covering floor vents with rugs to ensure unobstructed airflow and enhance cooling efficiency.


3. Optimize Wall-Mounted AC Placement:


Carefully position wall-mounted AC units to avoid obstructions from furniture like wardrobes and ensure proper ventilation for optimal efficiency.

In conclusion:

implementing these energy-saving tips can lead to significant reductions in your electricity bills while also contributing to a more sustainable environment. By being mindful of how you use your AC and making simple adjustments, you can enjoy comfortable indoor temperatures without breaking the bank.
