Bending sheet metal is a process of modifying the shape of sheet metal without having to remove any material. When sheet metal undergoes the bending process, the outer bend experiences stretching while the inner bend is compressed.

Frequently Asked Questions About Custom Ductwork

Where is the best spot to place ductwork?

The ideal spot to place ductwork is within the home’s thermal boundary. If you place it in an unconditioned basement or attic, you will lose significant efficiency, and your HVAC systems will have to work harder to keep you comfortable.

Why is sheet metal ideal for ductwork fabrication? 

Sheet metal is ideal because it is flexible, water-resistant, and facilitates streamlined airflow. Most ducts use galvanized mild steel, which is rust-resistant, durable, and lightweight, making it easy to install and maintain.

How important is precision cutting?

Precision cutting is crucial for ensuring a proper fit and a secure seal. If the cut is off by just a bit, it can create a gap that allows air to seep through the seam. Over time, a tiny gap can have a big impact on your monthly heating and cooling bills.

What can cause ductwork to fail?

Improper planning, poor manufacture, and incorrect installation are the most common causes of ductwork failure. For this reason, we spend considerable time planning each cut and checking each step to ensure everything fits tight and is installed correctly.

Our quality control processes are designed to deliver superior quality ducts you can depend on year after year.

How important is accurate duct sizing?

Accurate duct sizing is imperative! For example, if your ducts are too large, the air pressure won’t sufficiently distribute the air throughout your home. As a result, your comfort will be negatively affected. Your utility bills will increase in addition to wear and tear on your HVAC systems.

If your ducts are too small, this will cause static pressure to rise, increasing the amount of noise generated by the air moving through your ducts.

How long does it take to install new ductwork?

Generally, ductwork installation takes between one and four days to complete. It depends on the size of the property and the complexity of the installation.
