Air Conditioning Ductwork

One of the most overlooked yet essential part of every home is the air conditioning ductwork. When the air conditioner is in optimal condition, you can save a lot on the costs of heating and cooling your home. Further, an efficient duct system provides the right ventilation, keeping your family comfortable no matter the weather outside.


What is air conditioning ductwork used for?


The duct system is made of passageways used for proper ventilation or airflow. It supplies air and exhausts it from your home. Ductwork includes heating, ventilation, and air conditioning.

For example, the air is sucked from your house into an air conditioner or heater and then pushed back through the ductwork. Without proper return vents, you will begin to experience problems with air pressure and climate control.

Keep in mind that only air moves through the ductwork. The duct system does not include the pipes that transfer water or gas throughout your home.


Is it necessary to replace ductwork?


It is wise to check on your duct system every 15 years. This is the typical lifespan where ductwork runs efficiently. Although duct systems can last up to 25 years, most deterioration of ductwork begins after 15 years. Major issues such as collapsed ducts, gaps in the ductwork, and pests commonly appear around this time.


Understanding the Parts of Ductwork


Now, it is important to know the functioning of the ductwork by first understanding all of its key components:


● Air terminals- These components are the outlets that return air inlets, exhaust, and air supply through diffusers.

● Return and Supply Plenums- The return plenums carry air from the return vents into the air handler. Meanwhile, the supply plenums bring air to rooms that need heating or cooling.

● Smoke and fire dampers- When ducts need to pass through a firewall, this part of ductwork is included to seal off the duct immediately upon detection of fire or smoke. To reopen the ducts, an HVAC technician needs to do so manually.

● Stack boots and heads- The stack boot provides the transition from a duct to a relatively thinner duct in the wall. This allows vertical airflow in thin walls.

● Take-offs- You may notice several metal tabs fitted into the openings attached to the main duct. These allow small portions of airflow into branch ducts.

● Turning vanes- This component reduces air turbulence and resistance to airflow. These vanes guide the air and the direction it takes.

● Volume control dampers- This part of the duct system minimizes airflow volume either manually or automatically.

● Vibration isolators- These are inserted in the duct to minimize vibration. For instance, blowers create a vibration, which can create noise throughout the home. To avoid this, the rubberized vibration isolator is added.



Materials Used in Ductwork Installation and the Best Material to Use?


Some of the common materials used in duct systems include aluminum (because it is light and easy to install) or galvanized steel (typical or standard).

Other ductwork installation may use flexible plastic, fiberglass duct board, and polyurethane foam panels. A non-porous material like galvanized steel and aluminum is seen as the best options to prevent mold growth.


Keeping the Air Ducts Clean


Clean air ducts is important for the health of your family. Especially when there is a respiratory-related global pandemic, you need to make sure the air inside your home is clean. Air ducts can be filled with bacteria, mold spores, pollen, pet dander, mildew, and other harmful contaminants.

Further, air ducts can also get clogged with these air particles and make your HVAC equipment work less efficiently. Not just that, but you may encounter health issues. For healthier air circulation, keep your ductwork clean.

First and foremost, choose the right filters and check them once a month. Regularly vacuum particulate at least once a week as these can get trapped in the HVAC. Finally, schedule professional maintenance ductwork inspection, especially before the beginning of summer and winter.


Going Ductless


Modern heat pumps and split-system air conditioners do not rely on conventional duct systems. The equipment uses zoning strategies instead. Ductless air conditioning and heat pumps are common in the modern HVAC industry. You will need to consult an HVAC expert if you want to get a ductless system to ensure adequate ventilation in your home.
