Why Use Metal Ducting?

Before any replacement of metal ducting or HVAC systems, we strongly recommend having an expert check before you make any changes. That being said, here are some clear signs that your metal ducting has to be changed.

• Significant rust on the ductwork
• A reduced input/output (this can indicate a large amount of dust inside the ducting)
• Broken areas that allow air to escape, whether this is on the ducting pipe or the connecting joints
• Condensation on the ductwork
• If the ducting hasn’t been checked or worked on in years
• Mould in areas neighbouring the ducting (could be an indication of mould being within the ductwork.)

How does ducting get mould?

Unfortunately, mould can form in ducting, over time this can cause serious repercussions to your health and the overall health and performance of the ventilation system that the ducting is facilitating.

Essentially, mould forms in ducting due to condensation that can occur through breakage in the ducting, poor maintenance, and faults that cause humidity to form within the ducting.

Mainly, the likelihood of metal ductwork growing mould is very low. However, this can happen if certain circumstances are met. A clean, sealed duct will present an environment where mould can’t grow, this changes with the introduction of dust & humidity.

Can I prevent damage in my ducts?

Yes, it is entirely possible to prevent damage to your ducting, which can ensure it will last longer. Here are the most simple steps you can take…

• Cover the ducting with ducting insulation.
• Regularly check for any holes in the ducting
• Ensure any connections between the ducting are completely secure.
• Ensure that your ventilation system/ ducting is checked by a HVAC expert.
• Be vigilant by making sure the ducting is not near any leaks or water, or that no leaks have appeared near, next to, or in/on the ducting.

Can I still use metal ducting if it is rusted?

We would not recommend using ducting that has rusted, especially if the rusting is advanced. Rusting results in the rusted object flaking away, eventually, if left untreated or not replaced, this rusting can affect the structural integrity, as well as the general strength of the duct.

In some circumstances, items can be restored from rust damage, whilst an area of ducting that has rust damage should either be replaced entirely, or have the affected area removed and replaced.

Is there an alternative to ducting?

As yet, there is no alternative to ducting that can provide the same level of efficiency without the use of the ducts themselves. Alternative conduits have not been found. Although there may be other materials that can influence the effectiveness of a ducting system, they have not been distributed on a mainstream basis.
