The process of central AC system installation involves several steps. A central air conditioning company comes to the site and assesses it to find the best location for the outdoor unit and the indoor evaporator coil. Following this, the outdoor condenser is installed and connected to the indoor evaporator coil through refrigerant tubing. The system is then connected to the ductwork to distribute cooled air throughout the house. Finally, the newly installed system undergoes a thorough check to ensure it's working efficiently and safely.
