Ductwork VS Duct Work: What’s the Difference?

When referring to the ventilation aspect of HVAC, do you say “ductwork” or “duct work”? Word differences like this one might seem trivial to one. They might also be educational to another.

According to the Merriam-Webster dictionary, ductwork (one word) means “ducting” or “a system of ducts.” A duct (as a noun) is defined as “a pipe, tube, or channel that conveys a substance.”

Duct work (two words) is more appropriately used to describe work performed on ducts. Aire Serv has a nice one-liner on its blog, “It’s simple – if you want your ductwork to work, you’ve got to do a little duct work.” Read the full Aire Serv blog post here.

Let’s Recap:

  • Ductwork: a system of ducts
  • Duct: a pipe, tube, or channel that conveys a substance (HVAC ducts convey air)
  • Duct Work: work performed on ducts

Now that we’ve distinguished between ductwork and duct work, let’s take a deeper look at the latter: duct work (two words).

Quality Duct Work Improves HVAC Equipment Performance

Many HVAC contractors can overlook the importance of duct work: work performed on ducts. It’s one thing to install best-in-class SEER air conditioning units and AFUE furnaces. It’s another thing to ensure proper duct performance for distributing conditioned air to the desired rooms/spaces in a home or building.

The Journal of Light Construction published a helpful article about quality control for ductwork. Read the full story here.

Duct Cleaning: As you run your HVAC equipment and conditioned air gets distributed through your ductwork (one word), it’s important to clean your ducts to avoid buildup of nasty stuff like dust, dirt, and airborne allergens that can get blown into your living spaces.

Duct Insulating: When installing ductwork (one word), it’s important to wrap the ducts with insulation to avoid the conditioned air losing its conditioned temperature due to the external side of ducts being a different temperature than the inside of ducts.

Duct Sealing: To ensure proper duct performance, it’s important to plug any holes/cracks (big and small) in ducts where conditioned air can leak from the ducts before it reaches the desired room/space in a home or building.
