Ductwork Design Mistakes

Air Quality and Comfort Require HVAC Expertise

When companies undertake commercial construction and renovation, the checklist of considerations is daunting.

Air Conditioner on the RoofFrom contractor selection to building codes, from security systems to fire regulations, the list of things needing immediate attention often makes it easy to overlook some of the basics that are critical to both comfort and affordable energy costs.

Proper ductwork design is one of these.

Hot and cold spots, poor air quality, drafts, and even mold – these are the consequences of bad duct design and poor airflow. Comfort and energy efficiency are not to be taken for granted; they require expertise in HVAC ductwork design.

That’s our specialty at ZEN Industries. We not only make ductwork to specification, we are experts at system design, shop and coordination drawings, and advanced building information management.

Improper Duct Sizing and Sealing

When it comes to ductwork, one size does not fit all. One of the first considerations of Ductwork Fabricationduct design is the type and model of air conditioning units in use. Different rooms will have varying load, and rule of thumb calculations are rarely optimal.

The most common sizing problem is to make ductwork too small, creating a situation where the HVAC system cannot deliver adequate heating and cooling, regardless of the core system’s efficiency.

Is your contractor using the Air Conditioning Contractors of America’s (ACCA) Manual D Spreadsheet to determine duct size? Has your contractor or duct supplier used modern building information management (BIM) software to plot duct runs and fittings?

Bad duct sealing goes hand-in-hand with improper sizing to cause the most problems.

Air leaks waste, on average, as much as 20% of your conditioned air, putting it into wall spaces where it does little good. New, high efficiency systems are affected by air loss the most, as they are built to run at lower capacity and the air they condition has a greater chance of being lost through badly sealed ducts.

Too Many Fittings and Badly Placed Elbows

Roof Ducting It’s not always a question of poor planning and sloppy execution. Traditional methods of duct design are simply inadequate compared to the efficiencies possible with modern, 21st century software and experienced building information management.


Today, it’s possible to plan out an entire HVAC system in 3D detail, minimizing duct fittings and preventing conflicts with other disciplines, including plumbing and electrical runs. Badly placed elbows, too few returns, sharp bends, and unnecessary fittings are a thing of the past.


At ZEN Industries, we have the experience and proven methods to plan for the fewest fittings and to position elbows and duct runs for the greatest efficiency, and ultimately for the highest comfort.


Not surprisingly, efficiency and comfort are good for your budget too. Minimizing fittings and prefect sizing for duct runs means you save on both production and installation costs. Assuring that all fittings are placed properly in software means airflow can be optimized, making the most of today’s high efficiency systems.

Consequences Cost Money

Ceiling DuctworkTaking shortcuts in duct design doesn’t save money. What may seem like a quick solution during installation often contributes to a shorter life for your air conditioner, to air pressure differences that cause distracting noises or even slammed doors.

Even high-efficiency air conditioning needs to work harder, longer, and costs more due to badly designed delivery systems.

Mildew, mold, and allergens add to health costs that are difficult to measure.

Problems like these are why project managers, contractors, and architects turn to ZEN Industries. Our designers work hand-in-glove with our duct fabricators, making sure that every order is designed to provide for the comfort, health, and energy efficiency of the building in which it will be installed.

Add the facts that our duct products are affordable and delivered on time, and you can see why ZEN Industries has become a sought-after source of high quality duct and duct related services.
