• Compressor: The heart of the AC system, the compressor pressurizes the refrigerant, enabling it to circulate and cool the air.
• Condenser Coil: Located outside your home, the condenser coil dissipates heat from the refrigerant.
• Evaporator Coil: Situated inside your home, the evaporator coil absorbs heat from the air, cooling it down.
• Refrigerant: A special fluid that absorbs and releases heat, circulating through the system to cool the air.
• Fan Motors: These motors circulate air across the condenser and evaporator coils, facilitating heat transfer.
• Ductwork: The network of ducts that distributes cooled air throughout your home.
• Thermostat: The control center that regulates the AC unit’s operation based on the desired temperature.
