A rooftop unit installation is a type of air conditioning system that is installed on the roof of a building. This type of system is often used in commercial and industrial settings, where it is necessary to provide cooling and heating to large areas. The rooftop unit installation is a self-contained system that consists of an evaporator, condenser, compressor, and other components. The evaporator absorbs heat from the air and transfers it to the condenser, which then cools the air and sends it back into the building. The compressor then compresses the cooled air and sends it back into the building. The rooftop unit installation is a cost-effective and efficient way to provide cooling and heating to a large area. It is also relatively easy to install and maintain, making it a popular choice for many businesses.
