Duct tape is useful for repairing just about anything, but ironically, not for ductwork. Although the name may be misleading, general-purpose adhesive tape was by no means designed for use in HVAC ducts. In fact, if you tried to use “normal” duct tape on your ducts, it most likely wouldn't work. There are many things that live up to their name, unfortunately adhesive tape is not one of them.
While adhesive tape has many uses, wart removal is one that comes to mind. This sticky substance should never be used to seal ducts. The adhesive tape can adhere to even the toughest surfaces and is able to withstand many things. But it does not withstand extreme temperature changes in air ducts well.
Heating cycles can cause the adhesives on the adhesive tape to break. Over time, the adhesive tape weakens and ends up falling. Adhesive tape can withstand a lot of things. It's no secret that adhesive tape can bond even the toughest surfaces together. However, the only thing it can't withstand is heat and extreme temperature changes.
This is one of the many reasons why duct tape should never be used. Good morning, I'm Brandon from the air duct cleaning company Planet Duct in Colorado Springs. In this post, I want to talk about the importance of using the right adhesive tape for ducts. Despite its name, adhesive tape is not designed for air ducts.
Using adhesive tape on air ducts won't work, but luckily there are tapes designed for ducts. If you “fix” the ducts with adhesive tape, there may be a reduction in your energy bills, but this drop is temporary.
