AC Infographic

  1. Receiver Dryer
    The receiver dryer is designed to protect the air conditioner’s component parts from damage by absorbing moisture from the unit’s refrigerant.
  2. Expansion Valve
    The expansion valve removes pressure from the system’s refrigerant so it can expand or change from a liquid to gas in the evaporator.
  3. Condenser
    The condenser changes the A/C unit’s refrigerant from gas to liquid so it can continue its path through the system.
  4. Compressor
    Often referred to as the heart of the air conditioning system, the compressor circulates refrigerant throughout the unit to facilitate the air cooling process.
  5. Condenser Fan
    This fan is designed to cool the A/C unit’s condenser so it can effectively convert the system’s refrigerant from gas to liquid.
  6. Pressure Switch
    The pressure switch is a safety device that prevents damage to the air conditioning compressor by turning it off should the switch detect that the unit’s system pressure is too high or too low.
  7. Electric Disconnect
    Also commonly known as a switch box, the disconnect houses the breakers or fuses of the air conditioning system.
  8. Thermostat
    The thermostat is a device mounted on a wall that allows homeowners to control the temperature of their home.
  9. Service Valve
    Connected to the refrigerant side of the A/C unit, this device provides an access point so a technician can perform service work on the system.
  10. Contactor
    Controls the power to various parts of the air conditioning system by allowing or stopping electricity flow.
  11. Capacitor
    The capacitor stores electrical energy and is designed to give an A/C system’s compressor, fan motor and blower motor a sudden burst of voltage upon start up.
  12. Evaporator
    The evaporator coil is designed to absorb heat from the air being drawn into the A/C system from a home’s interior spaces.
  13. Filter Drier
    The filter drier acts to remove both particles and moisture from the refrigerant system.
  14. Filter
    Usually placed on the return section of an air conditioning system, filters are designed to trap contaminants such as pollen, dirt, dust and smoke so they do not enter the living spaces of a home.
  15. Blower
    A blower is a motor connected to the fan blades that moves air throughout the air conditioning system.
