What is air conditioning air ducts and why is it importance in your AC systems? Air ducts play an essential role in air conditioning systems. They are responsible for transporting air in and out of the home. The best way to ensure that your air conditioning ducts work perfectly in Dubai is by maintaining them regularly.

Your AC system is made up of compressors, condensers, fan, evaporator coil, and other tiny components. The air conditioning duct provides the raw material that they need to function: air. The duct system circulates cooled air from the compressor/condenser into the home and takes away the old air.

How Do Air Conditioning Air Ducts Work?

In most cases, the core cooling components of an AC unit is kept outside the building. This is done for two reasons, the first is for easy access to fresh air, and secondly, to keep the noise away. However, this makes it getting the chilled air into the building.

This is where your air conditioning air ducts come in. Ducting systems are designed to handle two types of airflow: air flowing in and air flowing out. This means that problems with your AC ducts have the potential to cause you some discomfort.

Importance of Air Ducts

Air ducts are your air conditioner’s main source of ventilation and the best place to filter the air coming into your home. Many air ducts today come with inbuilt filters to cleanse exterior air to remove dust, dirt, pollen, and contaminants that cause air contamination.

This is especially important in Dubai’s climate where the combination of high temperatures and higher humidity makes the heat really harsh. Your Air conditioning air ducts keep the desert sand, dirt, and other debris out of the building as it supplies clean air to your building.


However, this also means that pollutants can get into your home when your air ducts leak or gets bad. This can lead to foul air, asthmatic reactions, and other possible health symptoms. A buildup of contaminants can also reduce the efficiency of your AC system resulting in poor performance.

Make sure the air and your surrounding are pollution-free by keeping your AC ducts in good condition. You can do this by practicing proper duct maintenance or hiring the services of a professional AC maintenance company.

Different Types of Air Conditioning Air Ducts

The type of air conditioning duct or ducting system design you use will primarily depend on your unique needs. There are several different types available in the market today, but these are divided into two broad groups. These are:

1. Rigid ductwork

These types of ducts are inflexible and are often custom-designed for each use case. As a result of this, they are long-lasting, reliable, and often insulated. Rigid ducts come in a variety of shapes, sizes, and materials. The most common of them include:

Sheet metal ducts

This is the most common type of duct found in Dubai today. They are the shiny silver ones you see in action movies. They are constructed with steel or galvanized aluminum which makes them quite rigid and durable.

Sheet metal ducts come in different shapes including round, oval, and rectangular. They have a non-porous surface as a result of their material making them less likely to encourage mold than any other type of duct on this list.

Fiberglass lined ducts​

Fiberglass lined ducts

Sheet metals are often insulated from condensation and heat loss by lining them with fiberglass duct liner material. This insulation can be done inside or outside the duct and provide less surface area for heat, cold, or anything else to pass through.

Fiberglass liners also have the added advantage of reducing the sound of an operating AC system. This makes them especially popular in commercial buildings and restaurants in Dubai. Although the fiberglass lining is usually installed alongside the AC system, it can also be added later on.

You should be careful using liners as they may deteriorate over time and contaminate the air. It can be difficult cleaning fiberglass liners as this can damage them and reduce their effectiveness. Fiberglass lined ducts can also be contaminated with biomatter in the air.

Fiberboard ducts

This is another type of duct made of compressed resin polymer boards bonded with inorganic glass fibers. This construction makes fiberboard boards strong, durable, and highly efficient at trapping air and water vapor when wrapped with foil.

Fiberboard ducts are cheaper and easier to maintain than sheet metal ducts. They also offer many acoustical and thermal benefits. The insides of a fiberboard AC duct are often sealed with foil to prevent fiberglass particles from entering your AC system.


However, fiberboard ducts have the same drawbacks as fiberglass liners. They are more easily contaminated than sheet metal AC ducts. They also have a rough surface which can affect your air conditioner’s airflow and efficiency.

2. Flexible ductwork

Unlike rigid AC air ducts, flexible ducts often adaptable to many different configurations. They are tube-shaped and made of a spring steel wire mesh covered with a bendable, durable plastic. Some models come padded with special insulation to minimize noise.

Flexible ducts are mostly installed in areas where rigid ducts cannot be installed. In most cases, they are easier to install and cost less than rigid ducts. However, if not installed properly, they are also more likely to hamper the efficiency of your air conditioner. This can happen when they are installed with many bends and turns.
