Air conditioning is a way to make your home or office cooler and more comfortable. It works by taking the hot air in the room and turning it into cool air. To do this, it uses special equipment like a compressor, a fan, and coils to cool the air. The compressor squeezes the hot air, reducing its volume and making it colder. Then, the fan blows the cold air into the room so it will be cool. The coils help keep the air at a certain temperature so that you can be comfortable inside.
