Air Duct Services
A well-maintained air duct system plays a vital role in the efficiency and longevity of an HVAC system. Clean and properly adjusted air ducts help improve airflow, reduce energy consumption, and contribute to better indoor air quality. Regular maintenance can also extend the lifespan of the HVAC system and prevent costly repairs. In cases of urgent issues, such as a complete system failure during extreme weather conditions, prompt attention is necessary. However, scheduling routine air duct services can help prevent unexpected breakdowns and ensure optimal system performance.
Types of Air Ducts
Sheet Metal Ducts
Sheet metal is the most commonly used duct material. Made from galvanized steel, these ducts are typically formed into rectangular or round shapes. Many sheet metal ducts are lined with fiberglass insulation to improve energy efficiency and reduce noise. Their durability and resistance to mold make them a reliable choice for ductwork.
Fiberglass Duct Board
Fiberglass duct board is a cost-effective alternative to sheet metal ducts. While it provides good insulation and soundproofing, it is less durable and more susceptible to damage from pests such as mice. Additionally, fiberglass can develop mold over time if exposed to moisture. It is often used for the main trunk lines in a duct system, with smaller ducts branching off to individual rooms.
Flexible Ducts
Also known as flexduct, flexible ductwork consists of a wire coil covered by a plastic liner, fiberglass insulation, and a vapor barrier. It is commonly used in tight or irregular spaces where rigid ducts cannot be installed. Flexduct is also useful for connecting rigid ductwork to supply air registers. While it is quieter and easier to install, it can be less energy efficient and may become kinked or bent, restricting airflow. For these reasons, it is generally recommended to use flexible ducts sparingly and only when necessary.
By understanding the different types of air ducts and ensuring proper maintenance, homeowners can improve HVAC efficiency, reduce energy costs, and maintain a healthier indoor environment.
