When it comes to HVAC systems, ductwork is one of the most important components. Its main purpose is to distribute cold or warm air to the connected rooms in your home. There are four main types of ducts: flexible, rigid, semi-rigid, and sheet metal. Each type of duct system uses several materials to suit unique applications.
All HVAC system installations, repairs, and maintenance must be performed by a trained professional. Flexible ducts are usually round tubes made of steel wire propellers covered in flexible but durable plastic. Most flexible ducting is also surrounded by insulation to keep the air at the right temperature. This type of air duct is the easiest to install and is the second least expensive. Flexible ducting is the best type of ducting for use in cramped or uncomfortable spaces where rigid ducting would be too difficult to install.
Because these air ducts are flexible, they can bend around fixed structures to function in almost any space. However, flexible ducting is susceptible to bending and bending, which can restrict airflow and decrease the efficiency of the HVAC system. Airflow can also be reduced somewhat by ridges on the inside of the ducts. Another advantage of flexible ducting is that they are excellent for air quality. Because the ducts are made of plastic instead of fiberglass, which forms some rigid ducts, no dangerous particles are released into the air, meaning there are fewer air contaminants to inhale. This plastic is also resistant to mold and rust, meaning that air quality stays clean for much longer.
Flexible ducts have less chance of air leaking from the HVAC system than rigid ducts, although they are more prone to perforation. Rigid sheet metal is the most common type of ductwork. Made of galvanized steel or aluminum, it has a thick and solid wall that makes it very durable. The interior is known to trap dust and other particles, but its smooth surface is generally easy to clean. So, if you're opting for sheet metal in your home, it's a good idea to have the ducts professionally cleaned from time to time to maintain adequate air quality.
Because of their non-porous surface, they are also the least likely to withstand mold growth. The type of rigid ducts can also be coated with fiberglass. This type of duct is very similar to sheet metal ducts but has an inner or outer fiberglass lining. These ducts are preferred in commercial buildings and offices as air ducts lined with fiberglass have the ability to dampen the sound of air conditioning. Semi-rigid air ducts are made of a coil of metal wire and are covered with a flexible plastic layer. The flexible air duct also has thermal insulation made of glass wool, although other materials such as polyethylene or metallized PET can be used.
Flexible ducts usually look like a cube and have no elbows or deviations. Your home is likely to have a flexible air duct if you're short on space. When choosing the type of ducting for your HVAC system, review their qualities and select one that fits your needs and the type of home or building. If you still don't know what type of ductwork is the best choice for you, you can consult with HVAC experts. They can help you choose the right ductwork based on your property's design scheme, space, and budget. In addition, your ducts will need maintenance and cleaning.
In general, it's best to let them be installed by professionals as they know what type of duct is most convenient and suitable for you.
