Different Types of HVAC Ducts for Air Conditioners

Can’t decide which duct to choose for installing your air conditioners? You may be looking for professional assistance to clean your air ducts but are still determining the type you have in your home. We’ve got you covered. We will walk you through the different types of ducts and how to clean them.

1. Flexible HVAC Ductwork

This type of ductwork is constructed from a metal coil that is then covered by a flexible plastic layer. Flexible air ducts are also insulated with glass wool. Other materials, such as polyethylene or metalized plastic, can be used. Flexible ductwork is usually square-shaped and has no offsets or elbows. If you have a small house, your home likely has a flexible air duct.

2. Rigid Ductwork

Rigid ductwork is available in many different sizes, shapes, and materials. The rigid ductwork can be tailored to meet the customer’s needs. They are durable, hard, and reliable. There are three types of rigid air ducts:

3. Sheet Metal Ducts

This type of ductwork is usually made from aluminum or galvanized steel, but the latter is more popular due to its lighter weight and ease of assembly. Installing a sheet metal air duct means you won’t need to worry about mold and other dangerous growths. Both materials are non-porous, which prevents mold from growing in the ductwork.

4. Fiberglass Lined Ducts

Fiberglass can be used to line rigid ducts. The ducts are similar to sheet metal but have an internal or external fiberglass coating. The fiberglass-lined air ducts in these ducts can reduce the noise of air conditioners. They are used in offices and commercial buildings.

Fiberglass ducts are not recommended because they can deteriorate.

Releases small particles of glass into the air. Exposure to fiberglass particles over a long period can cause serious health problems, such as asthma. Fiberglass is porous and allows bacteria and mold to grow. The fiberglass-lined air vents are difficult to clean.

5. Fiberboard Ducts

Fiberboard is made of compressed, resin-bonded fiberglass that is laminated with foil. The lamination protects the fiberboard from moisture. Fiberboard air ducts are preferred by heating and cooling systems due to their insulation. These air ducts can also be a breeding ground for mold and bacteria, just as the fiberglass-lined ducts.

What Is the Best?

Many types of ductwork are on the market, but Sheet Metal is the most recommended. This type of air ductwork is non-porous and does not allow bacteria or mold to grow. The sheet metal ductwork can also help you avoid the health risks associated with fiberglass air ducts. Remember to regularly clean your duct system to maintain good indoor air quality. If you need help with how often to do this, you can read our article on how to clean air ducts.

You can choose a flexible duct if you are limited in space. Air ducts of this type are not only space-saving, but they also allow you to move them around.
