Can Flexible Ducts Be Cleaned?

Posted on Jul 1, 2021

A common question HVAC professionals hear is whether flexible ductwork can be cleaned. This type of duct work has been used in the HVAC industry for many years, as it is versatile and inexpensive. However, cleaning flexible ducts can be a challenge, especially for anyone who is not trained in the proper tools and techniques, as flexible ductwork is also easy to damage if not treated properly. 

What are Flexible Ducts?

Flexible ducts are basically what they sound like – instead of having a rigid ductwork system that cannot bend, flexible ducts are able to be bent and manipulated. You might have seen this type of ductwork running from your dryer to the exhaust output, or in a basement ceiling to get around plumbing. Flexible ducts consist of three layers: an outer polyethylene protective liner, fiberglass insulation and an inner polyethylene liner.

There are several reasons to use flexible duct work. The first is that it is easy to assemble and manipulate. Therefore, many homeowners use flexible ducts as their dryer exhaust duct work. If you must avoid obstacles with your duct work, such as pipers, electrical wiring or structures in the home, flexible ductwork is a great choice. Additionally, flexible ducts are cost-effective because they are insulated and inexpensive. 

Can flexible ducts be cleaned? 

In short, yes! Flexible ductwork, or flex duct, can be cleaned, and should be cleaned regularly, just like the regular HVAC ductwork in your home. However, flexible ducts should only be cleaned by a trained professional, as they can be easily damaged if they are cleaned using inadequate tools or by someone without experience cleaning these ducts. A company like Airpro Indoor Air Solutions has the expertise and tools to provide a thorough cleaning of all HVAC systems, including those consisting of flex duct work. Flexible ducts can be delicate and tend to deteriorate over time. This deterioration is sped up if the cleaning or maintenance are not done regularly or properly. 

Considerations when using flex duct work 

Flexible duct work has a lot of advantages – easy to use, inexpensive to buy, quick to manipulate around other objects in the home. However, there are some things to consider when working with flex ducts, including the length of the duct work and pest control. Flexible ducts should be kept fairly short, as static can build up in these types of ducts and airflow can be reduced. Additionally, pests such as rodents can more easily chew through the liner of these systems, meaning your duct work needs to be replaced. If the inner liner is torn, which is possible with pest infestations or inadequate cleaning, the fiberglass fibers can filter into your HVAC system and pollute the indoor air, which causes a health hazard for those in the home. However, all of these issues can be avoided with regular maintenance and professional cleaning.
