What does purge mean on air conditioner?

The most common reason you may hear a fan running constantly when there is no air conditioning running is because your air conditioner is purging. To understand why, we need to talk about the process of air conditioners. When an air conditioner cycles on, the compressor compresses the refrigerant to a high-pressure state. The pressurized refrigerant passes through the condenser coil where it gets cooled. Then the refrigerant passes through the expansion valve and into the air handler. The air handler

What does purge mean on an air conditioner?

The term purging is used mostly on air conditioners with ducts. A ductless system doesn’t have a single air handler unit. Instead each room or zone has an air handler (they look like boxy fans) that blows air into the space. If the air contains allergens or dust, it could be a health hazard. With a ductless system, the air handler is placed inside the room and blown out into the space, which means the air never comes in contact with

What does purge mean in the air conditioning system?

When air conditioners are in use, a fan motor forces air through the system to remove moisture and other pollutants. This process is called “purging.” This motion of air also causes dust and other airborne particles to be drawn into the system. This process is necessary to keep the system operating properly. If the system does not perform properly, it can severely damage the system, including the compressor, which is a very expensive component to replace.

What does purge mean in an air conditioner?

The purging process refers to the removal of moisture and contaminants from the air after the system has cooled an area to a comfortable temperature. This process uses the air handler to draw in fresh air, which is then cooled as it passes through the system’s condenser coils. The cooled air is then blown out of the vents throughout the house.

What does purge mean in an air handler?

Once the air conditioning system is operating, the heating and cooling coils that cycle the air through the system are constantly cycling on and off to distribute conditioned air to all the rooms in your home or office. Periodically, the system will cycle off when it reaches the end of its run, allowing the air to be replaced by unconditioned air. Once the system is turned off, the fan continues to run and causes air to be drawn into the air handler. This is the process known as “
