Which Kind of Ductwork Material Should You Use for Your HVAC System?

Your ductwork plays the critical role of directing heated or cooled air from your HVAC system to different parts of your home. It's also the channel through which air is returned to your furnace or air handler to be treated. You can choose between different ductwork materials, with each having its own perks and quirks. Let's explore the different types of ductwork material to help you identify the best one for your heating and cooling needs.

Sheet Metal

This type of ductwork is made of aluminum or galvanized steel. It's very durable, and its nonporous surface makes it the least likely to develop biological growth. The smooth interior surface usually traps particles like dust. If you choose sheet metal for your home, it's advisable to have the ducts cleaned by a professional occasionally to maintain good indoor air quality.

Fiberglass

Some sheet metal ducts have an internal or external fiberglass lining to insulate against heat loss. The lining lowers the HVAC system's sound, making it a popular option for offices and commercial buildings. With a sealed interior lining, the fiberglass ducts will need intense cleaning, which can reduce durability. Fiberglass ductwork can also be contaminated with mold and bacteria.

Fiberboard

Fiberboard ductwork is usually the most inexpensive ductwork system to install. It's constructed with resin-bonded fiberglass strands. The exterior has foil that serves as a water retarder and air barrier. The strands make the interior textured. Consequently, the crevices can trap dust and debris, posing an indoor air-quality concern. The rough surface can affect airflow and efficiency.

Flexible Ducts

Flexible ducts comprise a steel spring coil encapsulated in thick plastic. They're lightweight, inexpensive, and easy to install. Their flexibility makes them ideal for installation in tight spaces that can't accommodate rigid ductwork. Flexible ducts have inner ribs that cause more airflow restriction than sheet metal ducts.

Kinks, turns, and bends should be minimized during flexible duct installation, as they can hurt HVAC performance. Therefore, it's essential to work with a quality HVAC installer. Flexible ductwork is good for indoor air quality.

The best ductwork material for your home will depend on its overall design and your specific circumstances, such as the need for noise reduction or heat retention, as well as your budget. An experienced HVAC professional can give you proper guidance on ductwork material. Contact Air Assurance if you need assistance with any HVAC-related issues in the Broken Arrow area.

Suspect a Ductwork Issue? Some Common Reasons to Call for Help

Airflow obstructions can occur for a variety of reasons, many of which take place where you can't see them: in the ductwork. In addition to compromising your comfort, airflow issues can lead to energy waste, which will create noticeable increases in utility expenses.If you suspect a ductwork issue, there are a few things you can check on your own. Otherwise, there are some common duct issues that will require a call to an HVAC professional.Here are some common airflow issues you can check on your own:

• Dirty or clogged filters

• Obstructed vents

• Obstructed air intakes

If these don't seem to be the cause, it could be one of the following:Leaky ducts. If your ducts haven't been well maintained, and have developed leaks over the years, your conditioned air is able to escape into unconditioned spaces before it reaches your living space. In addition to obstructing airflow, duct leaks are a major source of energy waste. Once your technician has sealed the leaks, you will notice an immediate difference in interior comfort and lower utility bills.Obstructed ducts. There are a variety of reasons ducts can become obstructed. Sometimes it is the result of pest infestations. Obstructions can be the result of construction debris, dust and other debris that accumulates over time. Interior duct insulation can eventually collapse, which can also cause obstructions. Your HVAC contractor will remove any obstructions and may need to make some repairs depending on what he finds.Disconnected ducts. Sections of ducts are joined together via a series of connectors and joints. If the connections are just beginning to separate, it can cause the air to seep out. However, a major disconnection will completely shut down your air supply.Flex duct issues. Flex ducts are a popular choice for new duct designs because they are more flexible and eliminate the need for cumbersome and inefficient joints and connections. If the flex material collapses, or becomes compromised, it will obstruct air flow.Do you suspect your ductwork may have airflow problems? Call Air Assurance for help.
