How to Change an Air Conditioner Condenser

How Does a Home Air Conditioner Condenser Work?

One of the mina parts of a home air conditioner is a condenser coil. The condenser coil works in conjunction with the evaporator coil and the compressor to remove the hot air from a home while replacing this air with cool air to quickly reduce the internal temperature inside the home.


  1. A home air conditioner has three main parts that help it to cool down a home. The compressor, the condenser and the evaporator. These parts work together to remove the hot air from a home and replace it with air that has been cooled using a liquid that is easily converted into a gas form.

  2. An air conditioner compressor works in conjunction with an air conditioner compressor. The compressor draws in the liquid coolant and heats it. This heated coolant is then transferred from the compressor into the condenser.

  3. Once the heated liquid coolant is in the condenser it is then cooled using small vents that the liquid flows through. The liquid is continuously cooled until it reaches the end of these long hollow coils. 

  4. The liquid coolant once inside of the condenser is then put under pressure. This pressure forces the coolant out of the compressor and into a small valve which converts the liquid into a mist. 

  5. The coolant is then led through a set of hollow coils to help the liquid evaporate and cool down as it travels through these coils. This air is then blown across the cooled coils and up and out of vents throughout the home.

  6. Once the liquid has traveled throughout the air conditioning system, it is then fed through the coils back to the compressor where the process will be repeated as long as the air conditioning unit is running.
