The answer to 'what does installation do' is that installation is the process of properly setting up and configuring a new HVAC (Heating, Ventilation, and Air Conditioning) system in a home or building. This involves carefully positioning the indoor and outdoor units, connecting the ductwork, electrical wiring, and refrigerant lines, and ensuring the system is properly charged and functioning as intended.
A professional HVAC installer will follow specific manufacturer guidelines and industry best practices to ensure the system is installed safely, efficiently, and in compliance with local building codes. Proper installation is crucial for the long-term performance and energy efficiency of the HVAC system, as well as the comfort and safety of the occupants.
