Learn how to use air conditioning efficiently, reducing costs and maintaining comfort in your home effectively!
With temperatures rising, especially after a year of record heat in 2024, the use of air conditioning has become indispensable in many Brazilian homes. However, the electricity required to operate these appliances can significantly impact monthly bills. To maintain comfort without overdoing it on costs, understand the ideal temperature of operation is crucial.
The ideal temperature to reduce energy consumption
The temperature you set on your air conditioning directly affects the consumption of electricity.
According to Brazilian Association of Refrigeration, Air Conditioning and Ventilation (embrace), each degree below the recommended level can increase energy expenditure by 3,5%.

To save money, it is recommended to keep the temperature between 23°C and 25°C.
Studies show that adjusting the temperature of 23°C to 25°C can result in up to 7% savings of energy. This is due to the thermal load, which is the difference between the desired external and internal temperature.
Additional strategies for saving energy
For those who want to maintain lower temperatures, there are other ways to save energy:
- Ventilators: Use ceiling or portable fans to distribute cold air evenly, helping to cool the environment without increasing consumption. Fans are a complementary solution to air conditioning, as they help circulate fresh air, making the environment more pleasant and reducing the need to lower the air conditioning temperature too much.
- Natural ventilation: Open windows during cool mornings and evenings to allow fresh air to naturally flow in. This not only helps reduce air conditioning usage, but also improves indoor air quality.
- Insulation: Improve your home’s thermal insulation by sealing cracks and using curtains to block solar heat. Investing in double-glazed windows and well-sealed doors can reduce the exchange of heat between the inside and outside, keeping your home cooler in the summer and warmer in the winter.
- Device maintenance: Perform regular maintenance of the air conditioning, including changing filters and cleaning the coils, to ensure maximum efficiency. Clean filters not only improve the efficiency of the appliance, but also the air quality by removing dust, pollen and other allergens.
How to use air conditioning intelligently
The decision to leave the air conditioning turned on continuously or turned off at intervals can significantly affect the energy efficiency.
Keeping the appliance running at minimum power during the day can prevent overloading when cooling a hot room again.
During the night, use the function Better sleep to automatically adjust the temperature, ensuring comfort and savings.
This feature gradually adjusts the temperature throughout the night, saving energy while you sleep.
Selection of device and additional techniques
When choosing a new air conditioning, prefer models with high energy efficiency, classified as Procel A. Check whether the power of the appliance is adequate for the size of the room.
An undersized appliance will have to work harder to cool the space, while an oversized one will consume more energy than necessary.
Also, consider applying reflective paint on exterior walls and roofs to reduce heat absorption. Such paints reflect solar radiation, reducing the amount of heat that enters your home.
This technique is especially effective in hot, sunny climates, helping to keep the indoor temperature more pleasant.
Long-term benefits
Adopting these practices not only helps reduce immediate costs with electricity, but it also brings long-term benefits.
Energy efficiency contributes to environmental sustainability by reducing the carbon footprint and the demand for natural resources.
Additionally, appliances that operate efficiently have a longer lifespan, reducing the frequency of repairs or replacements.
By implementing these strategies, you not only save money, but you also actively participate in environmental preservation, promoting a more conscious use of energy resources.
In a global scenario where sustainability is increasingly crucial, these practices represent important steps towards a greener and more economical future.
