AC units

An air conditioning (AC) unit cools indoor spaces by removing heat and humidity from the air. It works using refrigerant, a special fluid that absorbs heat when it evaporates and releases heat when it condenses. The AC's compressor pressurizes the refrigerant, causing it to cool as it moves through coils inside and outside the unit. The cooled, dehumidified air is then circulated back into the room, providing a comfortable environment. AC units can also filter the air, improving indoor air quality. They are essential for maintaining a comfortable indoor temperature, especially during hot weather.
