The four main types of ductwork commonly used in HVAC systems are:
Flexible Ductwork
This type of ductwork is made from a metal wire coil and is covered with a layer of flexible plastic. These ducts are designed to be flexible and can be bent or shaped to fit into tight spaces or around obstacles. This makes them ideal for use in tight areas such as attics or crawl spaces.
Flexible ducts are easy to install and come with built-in insulation, typically made of glass wool or plastic materials such as polyethylene. They’re an excellent choice for tight spaces, such as attics or crawl spaces. A significant drawback of flexible ductwork is that it can be easily crushed and kinked, resulting in airflow restrictions. Also, they are susceptible to tears, leaks, and degradation over time.
Sheet Metal Ducts
Sheet metal ducts are the most common type of duct in the US. They are suitable for both residential and commercial applications. These ducts are usually made with galvanized steel or aluminium for their lightweight and easy installation. The best part of installing sheet metal ducts is that they are resistant to mold and bacterial growth. They are also durable, and their smooth surfaces reduce friction, improving airflow.
A significant drawback of sheet metal ducts is that they are expensive and labor-intensive to install. The other drawback is that they are poor insulators. If you have metal sheet ductwork in an unconditioned area, such as an attic or crawl space, the outside of the ducts needs to be wrapped with insulation to prevent heat transfer.
Fiberglass Lined Ducts
Fiberglass-lined ducts are very similar to sheet metal ducts; the only difference is that they have internal and external fiberglass lining. These ducts are preferred for commercial AC installations as they can help dampen the sound of your air conditioner.
This type of duct is not typically recommended due to its high installation cost. The biggest problem, however, is that it tends to trap lots of dust, allergens, and bacteria. Therefore, it will need to be cleaned more frequently; additionally, this type of duct is difficult to clean, which increases maintenance costs.
Additionally, fiberglass-lined ducts do not last long, and if they are not replaced promptly, they will begin to deteriorate, releasing fiberglass particles into the air. This is a significant health concern, as exposure to fiberglass can irritate the eyes, skin, throat, and lungs. Prolonged exposure to deteriorating fiberglass may pose health risks, including respiratory irritation.
Fiberboard Ducts
Fiberboard duct is made of compressed and resin-bonded fiberglass. The outside of the duct is laminated with a foil sheet, which protects it from moisture and acts as an air barrier for better insulation. The inside of the duct also features a special coating that fully seals the fiberboard, preventing fiberglass particles from escaping.
Fiberboard ducts are better insulated and have acoustic properties, making them perfect for commercial and industrial applications. Compared to sheet metal and fiberglass-lined ducts, these ducts are less expensive and easier to install.
However, a significant drawback is that they trap more dust and debris, which impacts indoor air quality. They are also challenging to clean and have rough interiors, which creates airflow resistance and highlights the relationship between AC ductwork and HVAC performance.
The Science Behind Airflow and Efficiency
Airflow affects everything from how quickly your house cools down to how fresh the air feels. When air is distributed evenly, your HVAC system doesn’t have to work as hard, which can extend its lifespan and save you money on repairs. The science behind airflow and efficiency lies in the relationship between air pressure, duct design, and system performance.
Static Air Pressure and Velocity
Air must move at the right speed and volume through ductwork to effectively cool your space. A narrow or dirty duct will create resistance, forcing your system to work harder. This reduces the efficiency of your system and the lifespan of your unit.
Air Leaks and Energy Loss
Leaky ducts are the most common reason behind the loss of efficiency. Conditioned air that escapes through the gaps puts a strain on your system, forcing it to work harder than necessary and increasing energy loss.
Air Return and Pressure Balance
Energy-efficient AC systems maintain a balance between the supply and return airflows, ensuring optimal performance. If the return air path is restricted, it can create negative pressure, drawing unconditioned air from outside, attics, and garages.
Installation Quality and Its Impact
The following are the ways ductwork AC installation can affect cooling performance and efficiency:
Proper Sizing for Efficiency
Ductwork installation must be sized to match the capacity of your system. Undersized ducts will reduce airflow and strain your system, while oversized ducts can reduce air velocity, resulting in poor air circulation and uneven cooling.
Sealing and Insulation
Poor sealing and insulation can result in a 20-30% decrease in cooling efficiency. When your air ducts are not properly sealed, it allows conditioned air to escape before it reaches your house. This leads to energy loss, forcing your system to work harder to compensate for the loss.
Balancing the System
A quality installation ensures that each room receives the correct volume of conditioned air. This helps enhance energy efficiency and ensures that no room gets too hot or too cold.
The Value of Trusted AC Installation
Working with a reputable HVAC installer in Orange County brings long-term benefits, including:
Accurate Load Calculations
One of the first steps a trusted installer takes for AC installation is performing a Manual J load calculation. This enhances ductwork and HVAC performance, ensuring proper air circulation and energy efficiency.
Code Compliance
Trusted HVAC professionals adhere to local, state, and national building codes, which are designed to protect homeowners and maintain energy standards. For example, in Orange County, California, Title 24 compliance is mandatory for AC and ductwork installation. The title ensures that systems are designed, installed, and tested to meet or exceed modern energy efficiency and safety standards.
Testing and Balancing
This ensures that your HVAC system and its ductwork deliver the right amount of airflow to every room in your home. It ensures optimal comfort, energy efficiency, and noise reduction, while also extending the lifespan of your air conditioner.
Duct Condition and Its Role in Long-Term Efficiency
