Air conditioning package units are an all-in-one solution for cooling and heating a space. They are designed to provide a complete climate control system in one self-contained unit. Package units are usually installed on the roof or outside of a building, and they are often used in commercial and industrial applications. Package units are composed of an outdoor condenser, evaporator, and compressor, as well as an indoor air handler. The outdoor unit is responsible for transferring heat from the inside of the building to the outside, while the indoor unit is responsible for distributing cooled or heated air throughout the space. Package units are a great option for businesses that need to control the temperature in a large area, as they are powerful and efficient. They are also relatively easy to install and maintain, making them a cost-effective choice for many businesses.
