Know Which Air Conditioning Temperature Consumes the Most Energy and Avoid an Increase in Your Electricity Bill of Up to 25%. Stay Informed About the Main Tips from Specialists!
As the end of winter approaches in Brazil, air conditioning becomes an essential ally for many homes and businesses. However, excessive use can lead to a significant increase in the electricity bill. According to energy efficiency specialists (Aneel), it is crucial to adopt conscious practices to avoid unexpected expenses in electricity consumption. With this in mind, this article explains which temperature settings make air conditioning consume more energy and how to use it more efficiently.
According to Thiago Barral, director of economic, energy, and environmental studies at the Energy Research Company (EPE), the use of air conditioning in homes in Brazil has tripled in the past 12 years. EPE projects that demand for electricity due to air conditioning use will continue to grow in the coming years. Barral believes that it is necessary to implement more ambitious minimum standards for air conditioning equipment to operate more efficiently regarding energy consumption.
Moreover, Samira Sousa, general coordinator of Energy Efficiency at the Ministry of Mines and Energy, emphasizes that significant energy losses can be mitigated with the conscious use of climate control devices. She reinforces that the encouragement of research in technology is essential: “Without innovation, new solutions cannot be created, nor can greater efficiency be generated.”

Know the Ideal Temperature of the Air Conditioner to Avoid an Increase in the Electricity Bill
One of the critical factors to consider is the temperature set on the unit. The lower the temperature, the greater the energy consumption. Therefore, it is necessary to avoid the air conditioning temperature that consumes the most energy. To optimize the use of air conditioning, it is recommended to set the temperature between 23° and 25°C.
This range not only provides thermal comfort but also helps keep the environment less dry, benefiting health. Additionally, each degree below this range can increase electricity consumption by up to 5%. Air conditioning, along with other appliances like refrigerators, is among the highest consumers of energy in a household.
Setting the unit to very low temperatures, such as 20°C, can elevate consumption by up to 25%, directly impacting the increase in your electricity bill. Therefore, knowing the air conditioning temperature that consumes the most energy is essential for reducing the electricity bill and fostering a more sustainable future. With just a few simple changes in daily habits, it is possible to enjoy thermal comfort without compromising the budget.
Tips to Avoid an Increase of Up to 25% in the Electricity Bill
To keep energy consumption under control and avoid an increase in the electricity bill, several practices can be utilized. Find a strategic position and avoid installing the air conditioner near heat sources, such as powerful lights; take advantage of natural heat to dry clothes, reducing the use of washing machines and dryers.
Another tip is to have efficient lighting by choosing LED bulbs, which consume up to 80% less energy than fluorescent lights; maximize natural light during the day. Also, turn off lights and electronics when not in use, even if they are plugged in.
Reduce shower time to save energy, regularly check the operation of the air conditioning and refrigerator, as damaged parts can increase consumption.
The main tip is to maintain regular maintenance of the air conditioner so that it continues to operate efficiently. Now that you know the air conditioning temperature that consumes the most energy, be aware that dirty or clogged filters can force the unit to work harder, increasing energy consumption. Additionally, preventive maintenance can prolong the life of the equipment and improve air quality in the environment.
Words from Experts on the Efficient Use of Air Conditioning
According to mechanical engineer Arnaldo Lopes Parra, vice president of marketing at the Brazilian Association of Refrigeration, Air Conditioning and Ventilation (Abrava) and expert in climate control (Abrava), the functioning of air conditioning can be compared to a vehicle’s fuel consumption.
He explains that when driving at 80 km/h on a flat road, consumption is lower than when going up a hill, as the engine’s demand is higher. Similarly, air conditioning consumes more energy when it needs to rapidly cool a very hot environment rather than maintaining a stable temperature over time.
According to Fernanda Roccon, architect at VRF Engenharia and postgraduate in climate engineering (VRF Engenharia), many people mistakenly believe that setting the air conditioning to the minimum temperature will make the environment cool faster. However, the unit is designed to operate continuously at a comfortable temperature, providing efficient cooling without overloading the system or excessively increasing energy consumption.
