In this article, we will provide detailed advice on the types of air ducts, how to choose, as well as factors that affect prices so that you can make the right decision for your project.
The Importance of Ductwork in HVAC Systems
Ductwork is the means of conducting air from the air conditioning system to the rooms and areas of use. A quality ductwork system will ensure:
- Distributes air evenly throughout the building, helping to maintain stable temperature and humidity.
- Optimize air conditioning performance, reduce energy consumption.
- Minimizes leaks, dust, and noise.
For large projects in Hai Phong such as shopping malls, office buildings or industrial factories, a quality duct system is a decisive factor in the stable operation and longevity of HVAC equipment.

Popular types of air ducts in Hai Phong
To choose the right air duct, you need to understand the types of air ducts that are commonly used. Each type has its own advantages, suitable for each need and project:
- Round air duct: Hai Phong round air duct is usually made from galvanized steel or stainless steel, with the advantage of stable air flow and low pressure loss. This type of duct is easy to construct, maintain and is suitable for both central air conditioning and industrial air exhaust systems.
- Square/rectangular air ducts: Hai Phong square air ducts help optimize ceiling space, suitable for projects with limited space. The product is easily combined with air boxes, air valves and other accessories, widely used in office buildings and commercial centers.
- Flexible duct (Flex duct): Hai Phong flexible duct is made of plastic or fabric, flexible in bending and installation in tight spaces. This is a cost-effective solution, suitable for renovation projects or areas where rigid ducts are difficult to install.
Factors affecting Hai Phong air duct quotation
When looking for Hai Phong air duct quotes, you need to pay attention to many factors that affect price and installation costs, specifically:
Duct material
Material is the most important factor affecting Hai Phong air duct quotation, because each type of material has different characteristics and prices.
- Galvanized steel is currently a popular choice thanks to its reasonable price, high durability and good oxidation resistance, suitable for most civil and industrial works.
- Stainless steel has outstanding advantages in terms of rust resistance, suitable for environments with high humidity or strict hygiene requirements such as food factories and hospitals; however, the cost is often higher than galvanized steel.
- Flexible ducts made of plastic or fabric are low cost, easy to construct and flexible but limited in lifespan and load-bearing capacity.
It is this difference that makes investors need to carefully consider between long-term efficiency and budget to choose the right material for the duct system.
Size and shape
Size and shape are also important factors that determine the price of air ducts in Hai Phong. Large-sized air ducts, serving high air flow, will of course have higher prices due to the cost of more production materials and more complex technical requirements.
In addition, the shape of the duct also makes a difference: round ducts are often cheaper than square or rectangular ducts for the same flow rate, thanks to their simple structure and low material consumption. However, square ducts have the advantage of saving space, being easy to arrange in low ceilings or narrow areas, so they are still chosen by many projects despite their higher price. Therefore, the choice of which type of duct depends on the construction conditions, design space and investment budget of the project owner.
Length and quantity
The length and quantity of ductwork in a project directly affects the overall cost. The larger the project, the more ductwork is required, resulting in a corresponding increase in material, transportation and construction costs.
However, not only the quantity but also the length of the pipe plays an important role. If the design system is unreasonable, requiring many long pipe sections or many complex joints, the cost will increase significantly. On the contrary, a scientific design, optimizing the air duct will help reduce the length of the pipe, saving both materials and installation effort. Therefore, to optimize the cost of Hai Phong air duct quotation, a careful survey and detailed drawings from the beginning will help investors avoid unnecessary costs.
Accessories included
Accessories that come with the ductwork also significantly affect the total quote, which many people often overlook when estimating costs. A complete system not only has ductwork but also needs important accessories such as air valves to adjust the flow, elbows to change the direction, flexible joints to reduce vibration and air boxes to distribute air evenly.
Depending on the scale and nature of the project, the quantity and type of accessories will vary, resulting in a difference in cost. In particular, for large projects or projects with high technical requirements, accessories are often ordered with good quality, ensuring durability and safety, leading to a higher overall cost. Therefore, when receiving a quote for Hai Phong air ducts, you need to request a clear list of all accompanying accessories to have an accurate view and avoid additional costs during the construction process.
Consulting on choosing the right air duct for your needs
To choose the right air duct, you need to determine the specific needs of the project:
For houses, apartments
For residential or apartment projects, especially small spaces and low ceilings, the choice of air ducts should prioritize compactness, flexibility and ease of maintenance. Round air ducts are a popular choice thanks to their stable air conduction, low pressure loss and quick installation in limited spaces. In addition, flexible air ducts are also very suitable for apartments because they are easy to bend and convenient to install in complex areas such as false ceilings, narrow corners or sub-pipes.
In terms of materials, galvanized steel is often preferred because of its high durability, good rust resistance and reasonable cost compared to stainless steel. For families who want to save costs while still ensuring efficiency, flexible air ducts combined with round galvanized steel air ducts will be the optimal solution. In addition, focusing on periodic maintenance and cleaning of air ducts will help the system operate stably, maintaining fresh air quality for the living space.

For offices, shopping centers
For large-scale projects such as office buildings or shopping centers in Hai Phong, the duct system needs to ensure strong, stable air circulation and energy savings. Round or rectangular ducts are often used because they can withstand large air flows and are easy to arrange in technical ceiling spaces.
Suitable materials for these projects are galvanized steel or stainless steel, ensuring high durability and long-term operation. In addition, the scientific design of the branching system plays an important role in distributing air evenly to all areas, avoiding uneven hot and cold rooms.
In addition, in shopping malls, aesthetics are also of concern, so many investors often choose square ducts combined with air boxes to easily hide behind plaster ceilings. Therefore, when looking for Hai Phong duct quotes for offices or shopping malls, it is necessary to carefully consider cost, durability and ability to meet large flow.
For factories and industrial parks
Factories and industrial zones are structures with their own characteristics, often operating in dusty environments, high humidity or corrosive chemicals. Therefore, the most suitable type of air duct is stainless steel or galvanized steel, which is rust-resistant, strong and adaptable to harsh environments. The air duct system here is often large in size to meet the need for strong air circulation, ensuring a well-ventilated working environment for workers and machinery.
In addition, the combination with flow control valves makes it easy to control the air in each production area, both optimizing performance and saving energy. With a large scale, the process of designing and installing the ventilation system in the factory requires an experienced unit to ensure safety and efficient operation. Therefore, when choosing ventilation for industrial parks in Hai Phong, investors not only care about the price but also have to consider the reputation and construction capacity of the contractor to avoid incurring repair costs later.
