The different types of air conditioning ducts

Air conditioning has become a necessity for people living in hot and humid climates as well as commercial spaces such as schools, offices, hotels and retail stores. Air conditioning helps with comfort and productivity as well as offering a string of health benefits and improved air quality. If you’ve ever wondered how air conditioning works or ran into a problem with your current unit, you might have come across the duts. An important component which distributes cooled or heated air throughout the premises.

With so many different types of units on the market, there also comes a range of ducts to choose from, each one offering a new benefit or feature.

Types of air conditioning ducts

Sheet metal ducts

These are the most common types of ducts found in domestic and commercial buildings. Sheet metal ducts are made of galvanised steel, aluminium or stainless steel and come in rectangular or circular shapes providing flexibility. They are easy to install, durable and cost-effective.

Flexible ducts

Made of a combination of plastic and metal wire, which makes them flexible and easy to install, flexible ducts come in different sizes and shapes and are often used in places where sheet metal ducts cannot fit. Providing energy efficiency, this option makes them a popular choice for residential buildings as homeowners can save on energy bills and energy consumption.


Fibreglass ducts are made from glass fibre and are known for their insulation properties, making them ideal for homes and offices. They are also easy to install and require minimal maintenance.

Duct board ducts

Made of a rigid board material that is covered in fibreglass insulation, duct board ducts are lightweight and easy to install as well as being energy efficient.

Panned joist ducts

Panned joist ducts are a type of duct that is installed between the joists in the floor or ceiling. They are often used in older homes but can also be installed in any orientation. This type of duct is often used to extend the reach of an existing duct system.

How to choose an air conditioning duct type

A professional air conditioning company can help you select the right type of duct for your specific needs and ensure that it is installed correctly depending on your property, your personal needs, the system type you have and the primary purpose of the unit.

  • Size and layout of your building or space
