Air Conditioning Component: AC Condenser - Houston's Premier Auto Repair Facility

The capacitor is needed in order to cool the refrigerant that is heated up by the compression in the compressor. The hot refrigerant gas flows into the condenser and transfers heat to the surroundings via the pipe and fins. As it cools down, the state of the refrigerant changes again from gaseous to liquid.


How they work

The hot refrigerant gas flows on top into the condenser and transfers heat to the surroundings via the pipe and fins. Due to cooling down, the refrigerant exits the condenser at the lower connection in liquid state.


Effects of failure

A defective condenser may exhibit the following systems:

  • Poor cooling performance
  • Failure of the air conditioning system
  • Continuously running condenser fan


Causes for occurring faults can be:

  • Leaks at the connections caused by damage
  • Insufficient heat exchange due to contamination
