A ducted air conditioning system is a type of central air conditioning system that uses ducts to distribute cooled or heated air throughout a building. The system consists of an indoor unit, which is installed in a central location, and an outdoor unit, which is installed outside the building. The indoor unit is connected to the outdoor unit by a system of ducts, through which the cooled or heated air is circulated.

A ducted air conditioning system works by drawing in air from the room, cooling or heating it, and then circulating the cooled or heated air back into the room through a system of ducts. The indoor unit contains a refrigerant that is used to cool or heat the air, depending on the desired temperature. The outdoor unit contains a compressor and an expansion valve, which work together to control the flow of refrigerant and regulate the temperature of the air being circulated.

There are several benefits to using a ducted air conditioning system:

• Ducted air conditioning systems can cool or heat a large area, making them ideal for
  use in large buildings or homes.
• Ducted systems are generally more energy-efficient than other types of air
  conditioning systems, as they allow for more precise temperature control and
  distribute the cooled or heated air evenly throughout the building.
• Ducted systems are generally quieter than other types of air conditioning systems,
  as the indoor unit is typically located in a central location and the noise is dissipated throughout the ducts.
• Ducted systems can be controlled by a central thermostat, allowing you to set the
  temperature and control the system from a single location.

To ensure that your ducted air conditioning system is operating efficiently and effectively, it is important to perform regular maintenance. This includes:

• Changing the air filter regularly to ensure that the air being circulated is clean and free of contaminants.
• Checking and cleaning the ducts regularly to ensure that they are free of dust, debris, and other contaminants.
• Cleaning the indoor and outdoor units regularly to remove any dirt or dust that may have accumulated.
• Having the system serviced by a professional technician on a regular basis to
  identify and repair any potential issues.

It is also important to follow the manufacturer’s recommendations for maintaining your
ducted air conditioning system to ensure optimal performance and longevity.
