How to use AC to reduce electricity bill

In the ancient days, Air Conditioner (AC) was recognized as a luxury item. Yet, now it has become an inevitable part of every day. The use of air conditioning is poised to get increase dramatically over the next several few decades as global temperature is going up. But still, the use of ACs in India has become rampant in this digital paradox. In this context, it is wise to prefer energy efficient Air Conditioner.

Keeping a vigil upon the customer’s interest, many companies are now providing smart ACs for better and reliable use. Thankfully innovations have reached its heights. However, the real problem knocks in at the time of paying the electricity bill. The article is all about how to reap more off this cooling machine without spending much from our pocket.

Air conditioners today are more energy efficient and cost effective than before. Brands are now launching highly energy efficient five-star BEE rating ACs with exceptional design and features. The huge variety is sure to perplex the consumers.

Every user should aware about the effective use and classification of ACs. Here we explain in detail about the use of AC with minimum power supply.

Categories of ACs

The different categories of ACs available in the market are: Window air conditioner, Split air conditioner, Inverter air conditioner; Ductless mini split A/C units, Wi-Fi qualified/ smart air conditioner, portable air conditioner and solar air conditioner, etc.

The power cost for operating an AC depends upon its power performance as designed by the company, the amount of working hours and how efficiently we run and maintain it.

Functioning of an Air Conditioner

Primary elements of the functioning of an AC include a compressor, evaporator, condenser, and an extension device, like the one in a family refrigerator. A refrigerant flows in those parts. It vaporizes in the evaporator grasping the temperature from the warm space air drawn over the evaporator roll. This chills and dehumidifies the air in a room. The compressor increases the load and heat of the refrigerant gases. The condenser consolidates the refrigerant and then converts the high-pressure vapour into the huge-pressure fluid. Heat is refused via external air carried across the condenser. The extension mechanism converts the high-pressure and high-temperature fluid refrigerant to low heat blend of the refrigerant fluid and vapour. The refrigerant passes to the evaporator, and the cooling series remains active.

In the summer in India, it is too tough to live without an air conditioner. It seems modern people have made their body habitual for these cooling products. Air conditioners are the most efficient way to cool ourselves down and they are now cost-effective as well. However, we can’t control the amount of energy they consume which ultimately costs us more.

Inventions of energy efficient air conditioners are proved to be a blessing in disguise. While it’s better for the environment it certainly is also for your budget. We can find benefits like superior performance, longer lifespan, lower energy bills, environment-friendly refrigerant, and complete climate control, cooling is quiet and sleek by the installation of energy efficient air conditioners.

It always is good to buy an energy efficient air conditioner with a high BEE rating to reduce energy consumption. It has been observed that during the summers in India, an average central AC uses 3000-5000 watts of power each hour for around 9 hours a day. Depending on the outside temperature, a central AC runs 3-7 months of the year as per the climate of the region.


By following the following easy steps, you can increase the efficacy of your AC with a reduced power bill.

  • Be economic while running your AC
  • Maintain your AC
  • Use a ceiling fan
  • Avoid other heat generating devices in the day time
  • Prevent your room from sunlight
  • Service your AC regularly
  • Perfect lighting is also important
  • Keep your computer shutdown
  • Carefully reduce the other heat gainers
  • Use Copper Ac instead of Aluminium Ac
  • Install an attic fan to pull the cool air into your room

Factors that influence the electricity/power load

  • Outdoor temperature
  • Indoor air temperature
  • Thermal insulation of the room
  • The temperature setting of the air conditioner system

Keep these points in mind when buying an AC

  • Energy Efficiency Rating (BEE Rating)

Today, the bee rating is provided to all kinds of appliances so as to know its power consumption rate. These ratings are given out of five and provide basic information about how energy efficient the appliance is. Further, these are in correspondence to the Bureau of Energy Efficiency of India (BEE). The higher the rating the lower is the energy consumption. The best energy efficient air conditioners are the one with the five-star rating.

  • EER and SEER; understanding efficacy ratio

Energy Efficiency Ratio (EER) determines the functional competence in the cooling effect of the AC at a fixed outdoor degree of 95.  Higher the ratio higher would be its efficiency during the peak hour in a day. Seasonal Energy Efficiency Ratio (SEER) on the other hand is used to measure the competency on the basis of seasons where there is maximum usage.

Save money & stay cool with these energy saving tips

  • Keep the AC Lower at Night
  • Keep your filters clean
  • Maintain ducts and vents
  • Check for household leaks
  • Reduce heat sources
  • Use fans strategically
  • Set a realistic temperature

An Air conditioner in India works to cool air by 15 degrees at a time. It is ideal to maintain the room temperature at 24-26 degrees which help in two ways. It enhances the efficiency of your AC and lowers power consumption simultaneously.

According to the Energy Department of India, setting your air conditioner in 26 degrees Centigrade allows you to stay cool in summer and avoid the high electricity bill.

It is also recommended to run the fan if the heat exchanger is disabled. When it comes to energy efficient air conditioners, different products work best for different people. You should consider the space and your personal habits when deciding on a type of system. Be sure to contact professional installers who can offer efficient products and installation.

Also, choose an ENERGY STAR certified model. With high EER and SEER levels, you can count on it to provide you with inexpensive cooling season after season.

Of course, when it comes to comfort budget does not mean much for many. An air conditioner is definitely harmful to the environment, but with new technology and innovation, we can always minimize the risk and still enjoy sitting in a cool room.

When we return home after spending a hot day outside, sitting down in a cool room with an AC is one of the best feelings ever. Eventually, a smart decision in buying smart AC leads you free from lavish.
