- When the heat is very high outside, the air conditioning will never cool everything down. Set the temperature of your air to room temperature about 23-24 degrees. Otherwise they only waste electricity, since the compressor never cuts off because it never reaches the temperature they asked for. Some air conditioners have an ecological or intelligent mode, based on the temperature outside and inside the house, it decides what the ideal temperature is to cool down and use less electricity. 2. Do not try to use the air conditioning to cool a larger area than it was designed for. The 1-ton air is made for medium-sized rooms of 16m2, with a king bed, a bureau and that's it. A 2-ton air is made for the living room and dining room of a 32m2 house, with the kitchen door closed. A 3-ton air is made for the first floor of a house of approximately 48m2. Just imagine trying to open the refrigerator to cool your kitchen, you simply can't, you only use more electricity. Close doors and windows in the area to be cooled to prevent heat from entering or cold from leaving. __ There is no point in setting the climate at 16º C, it will never reach it and that is why the power goes out in the neighborhoods, because we all have overloaded compressors working at forced marches.
