• Evaporator Coil: Located inside, the evaporator coil absorbs heat from the air inside your home, cooling it down.
• Refrigerant: A specialized fluid that absorbs and releases heat, circulating throughout the system.
• Blower Motor: This motor drives the fan that circulates air across the evaporator coil and through the ductwork, distributing cool air throughout your home.
• Ductwork: The network of ducts that carries the cooled air from the AC unit to the vents in your rooms.
• Thermostat: The control center that monitors the temperature and signals the AC unit to turn on or off.
