Air conditioning: 5 tips that help save energy

The air conditioner is present in a large part of Brazilian homes, especially in the warmer regions, and has become a fundamental element for thermal comfort in everyday life. However, like any high-power appliance, its continuous use can weigh on the electricity bill if some basic care is not observed. With small adaptations in the routine and attention to details of cleaning, installation, and operation, the air conditioner can operate more efficiently, consuming less energy without losing performance. It is this balance between comfort and savings that guides the best practices presented below.

1. Perform periodic filter maintenance

Keeping the air conditioner filter clean is one of the simplest yet most decisive steps for the good performance of the appliance. When the screen accumulates dust, the airflow becomes restricted, the motor works harder than necessary, and energy consumption increases. In addition, the air circulating in the projects loses quality, which can cause respiratory irritations.

The ideal is to clean the filter every 15 days or as per the manufacturer's instructions, especially on days of intense use. In many models, the process is quick: just remove the screen, wash it with running water and let it dry in the shade. This routine not only reduces expenses but also prolongs the useful life of the air conditioner.

2. Adjust the temperature for more efficient use

The temperature setting also directly affects energy consumption. The lower the number chosen on the remote control, the greater the effort of the air conditioner to cool the projects. Therefore, temperatures between 23 °C and 25 °C are typically the most efficient for combining comfort and savings.

Another helpful feature is the “automatic” or “economical” mode, available in most models. It allows the appliance to adjust its operating intensity according to the needs of the space, avoiding unnecessary energy spikes. In addition, a smart combination with curtains and blinds helps to block external heat, reducing the demand for cooling.

3. Check the installation and insulation of the projects

The efficiency of the air conditioner starts with the installation. A poorly positioned appliance or one with insufficient sealing loses part of the cooled air, requiring more effort to maintain a stable temperature. Windows with gaps, doors that do not close well, and surfaces that are heavily exposed to sunlight can compromise performance.

The solution involves simple adjustments, such as using weatherstripping, checking the closure of the frames, and, if possible, installing the air conditioner in areas that do not receive direct sunlight. These details influence not only the savings but also the thermal comfort in general.

4. Use the timer to avoid prolonged use

The timer is a resource that is often underestimated but can make a significant difference in savings. By programming the air conditioner to turn off during the night or shortly before leaving home, continuous and unnecessary use is avoided, especially at times when the projects are already comfortable.

This function can also be used as a gradual cooling strategy: simply adjust it so that the appliance reduces its power before turning off completely. In addition to keeping the room pleasant during sleep, this routine contributes to a more balanced consumption.

5. Avoid internal sources of heat

Several elements inside the house can directly influence the performance of the air conditioner. Electronic equipment being on for long periods, very hot lamps, and even the habit of leaving the stove on in integrated kitchens end up raising the internal temperature.

By reducing these sources of heat, the air conditioner needs to work less to reach the desired temperature. Small actions, like turning off computers when not in use or replacing hot bulbs with LED options, contribute to a cooler and more economical environment.
