How Does an AC Expansion Valve Work?
When it comes to your air conditioner you have many parts that are individual and work with the unit to ensure it is running. These parts can start to have a problem and can end up with issues that mean they need to be replaced. The expansion valve is part of the outside unit that works with the refrigerant. The refrigerant is in the unit as a liquid. It has to be cooled and changed to a gas so that it can carry the cold air to the house. The cooled refrigerant will help to take the heat out of the house and release it outside. This is done on a constant basis as your AC is working. Once the heat has been released the gas has to change back to liquid so that it can be cooled. The problem is that it is too hot and it cannot be sent back. This is where the expansion valve comes into play. It is there to use pressure to move the warmed refrigerant into the chamber so that it can be cooled and used again. If this part is not working you will start to see signs of problems.
