A portable air conditioner is a compact cooling unit designed to provide relief from heat in various spaces. Unlike traditional air conditioning systems, it does not require permanent installation, making it easy to move from room to room. These units typically use a hose to vent hot air outside, while circulating cool air indoors. Most portable air conditioners come with adjustable settings, allowing users to control the temperature and fan speed. They often include features like a built-in dehumidifier and programmable timers, enhancing comfort and energy efficiency. This makes them a popular choice for homes, offices, and temporary living spaces.
