Whether in summer or winter, the air conditioner is one of the most used options in Portugal for keeping the home temperature pleasant. However, if you do not take precautions, you might have a very unpleasant surprise when you receive your electricity bill. Therefore, we have compiled some tips on how to maximise the efficiency of your air conditioner and save energy:
Pay attention to energy efficiency when buying a unit and ask for help from a salesperson to find out which is the best option in terms of price and average consumption. A unit might be more expensive, but having a greater energy efficiency will translate into savings in the long run.
Do you intend to use the unit in various rooms of the house or just one? Then, be careful to choose a model suitable for your needs. To do this, measure the square metres of the area that the unit needs to cool. There are models designed for small spaces and others for larger spaces. Be careful, because if you choose a unit designed for a smaller area than the one you intend to cool, the unit will have to be used at maximum capacity, which implies greater effort and consequently higher energy consumption.
Furthermore, good thermal insulation in walls, ceilings, and windows can prevent cool air from escaping and hot air from entering. Make sure that doors and windows are well sealed and consider installing thermal curtains or blinds to reduce heat entry during the day. Using reflective films on the windows can also help keep the internal temperature lower.
Try to avoid internal heat sources by minimising the use of appliances that generate heat, such as ovens and incandescent light bulbs, during the hottest periods of the day. Cooking outdoors or using the microwave can reduce the heat load inside the house, for example. Replacing incandescent bulbs with LEDs can also be an option, as they are more efficient and emit less heat.
Frequent cleaning of the filters not only results in energy savings and efficiency but also promotes the well-being and health of the occupants of the space. Clean filters allow for adequate airflow, improving the performance of the unit and preventing system overloads. This not only reduces energy consumption but also extends the lifespan of the air conditioner and ensures a healthier indoor environment.
Curtains and blinds also play an important role in maintaining a pleasant internal temperature. During the hottest hours of the day, keep curtains or blinds closed to block the entry of heat. Blackout curtains are especially effective at reducing heat transfer, helping the air conditioner work more efficiently.
Essentially, maximising the efficiency of your air conditioner is an ongoing effort that involves implementing several simple but effective practices. By following these additional recommendations, you can enjoy a cool and comfortable environment while reducing your electricity bills and minimising your environmental impact. Remember, every little action counts towards creating a more sustainable and efficient use of your air conditioner.
