Does the Ductwork Material You Choose Impact Your HVAC?

Installing new ductwork material can be a significant undertaking. Whether it’s a new home or a retrofit, the decision will be part of your heating and cooling for years to come. That means it’s important to get it right. There are several kinds of ductwork material to choose from. What’s the difference between them? Which one is best for your home? Let’s take a look.

  • Sheet metal. Hard and durable, these ducts are much less prone to leaking than other types of ducts, which can save you energy. However, they also gather dust more easily. That dust is then circulated through your home. Fortunately, the smooth surface makes it easy to clean. Consider having your ducts professionally cleaned every few years to boost AC performance and IAQ.  Properly installed sheet metal ductwork is sealed with a paint on type sealer called mastic making it the most efficient system you can install so long as it is also properly insulated with R8 ductwrap type insulation.
  • Fiberboard. An outer layer of foil protects the interior resin and fiberglass ducts. This is usually the cheapest ductwork material to buy and install, and it is well-insulated to save energy. In humid climates, it also attracts moisture, which may foster mold and mildew inside the duct. This can be particularly problematic during the Georgia summer.  Never recommended by our firm.
  • Fiberglass. Most notable for reducing AC noise.  Furthermore, the fiberglass lining helps reduce heat loss as air travels through the ducts. However, it’s also less durable than other materials, making it more prone to leaks when not properly installed with staples, tape, and mastic products.  
  • Flexible. Made of wire and plastic polymer, these ducts can bend and change shape, making them a great option for fitting into tight or hard-to-reach places. Installation on these ducts seems fairly simple — so much so that some homeowners attempt it themselves. However, without proper training in ductwork installation, you can easily put too many bends and kinks into these ducts. As a result, air has a harder time going through them. They’re also prone to punctures and other damage, which result in leaks.  When connecting these ducts to the main ductwork whether it is sheet metal or fiberglass you must properly connect and seal the connection or your loose significant airflow.  In Georgia, it is now required to install R8 flex ductwork for energy consumption savings.
