The duct’s efficiency will determine the intake and output of air. Therefore, ensure that the installation is done correctly to ensure that the air pressure, cooling, and heating systems performance are balanced.

Importance of Proper Installation

When ductwork is installed correctly, it will keep the whole house comfortable, distributing the temperature evenly around the house. Poor installation will bring several problems. For example, you may experience air leakages. It will make the whole system work inefficiently, and the air quality will be inferior. It may cause the entire air conditioning and the heating system to fail. It will add more cost when it comes to repairs.

For proper installation, ensure that the sizing of the ductwork is checked. The size of the ductwork should always match the size of your air conditioning and heaters. It will ensure that their performance is as efficient as possible. When your ductwork is done correctly by professionals, it will ensure the system has a long-lasting optimal efficiency. The duct will adequately distribute airflow to all the rooms in the house or the buildings.

Materials Used to Make Ductwork

Aluminum

Ductwork made using aluminum is very light, which makes it very easy to install. Aluminum is easy to customize in unique shapes according to the site or the shop.

Galvanized Steel

They are the most popularly used materials to fabricate the ductwork. A zinc coating prevents metals from rusting. Therefore, you will cut on painting costs. The metal ducts will be lined with duct liners or wrapped with a duct wrap on the outside. In certain circumstances, a doubled-wall vent will be required.

Polyurethane and the Phenolic Panels

The form panel is made using a factory-made aluminum finish inside and outside. Aluminum foil thickness will vary depending on whether it’s used on the inside or outside.

Fiberglass Duct Boards

These types of panels are made for built-in thermal insulators. The interior surfaces absorb noise and provide quiet air conditioning and heating operation unit.

Flexible Ducts

The ducts are manufactured using flexible plastic covering metal wire coils that form a tube-like shape. These flexible ducts come in a large selection. They are very suitable for attaching air supply outlets to ductworks that are not easy to bend.

Components of Duct Systems

Apart from the duct itself, a duct system has several other parts. The parts work together with the vent to offer quality air conditioning to your entire house.

Vibration Isolator

They are placed in the duct before air handlers to reduce vibrations and noise when the system is in operation.

Take-Offs

Volume Control Dampers

The duct systems require ways to regulate airflow magnitude to different sections of the unit. The dampers can be automated or manual.

Smoke and Fire Dampers

They are found in systems that pass through fire curtains and firewalls. They are designed to automatically seal the duct when they detect any smoke or fire. They stay sealed until manually opened by a technician.

Turning Vanes

They are placed in the ductworks to help minimize resistance and irregular motion to airflows. The air gets controlled by the vanes and can easily alter direction.

Air Terminals

It’s an outlet that helps supply and exhaust air. When it comes to air supply, you will find diffusers in small HVAC units mostly installed in residential housing. Grilles used for exhausting is only for appearances. However, some are fitted with air filters.
