A rooftop AC installation is the process of installing an air conditioning unit on the roof of a building. This type of installation is often used in commercial buildings, such as office buildings, schools, and hospitals, as well as in residential homes. The rooftop AC installation process involves the mounting of the AC unit onto the roof, as well as the installation of the necessary ductwork and wiring. The installation of the AC unit is done by a professional HVAC technician, who will assess the size and weight of the unit and ensure that it is properly secured to the roof. The technician will also make sure that the necessary ductwork and wiring are properly installed and connected to the AC unit. Once the installation is complete, the AC unit will be able to provide cool air to the building, helping to maintain a comfortable temperature.
