Replacing Commercial Ductwork

Duct Renovation in Commercial BuildingIn any commercial building, HVAC ductwork plays a vital role in maintaining a livable climate.

 Both employees and customers benefit from a building with a comfortable indoor environment, thanks to a properly functioning HVAC system and modern ductwork.

While a good duct system can last 20 years or more, HVAC ductwork is susceptible to age and deterioration over time, often with noticeable effects. Making sure your ductwork is up to date and functioning properly ensures a comfortable working environment, promotes energy efficiency, and even increases worker productivity.

In this article, we take a look at the signs of aging ductwork, and how ZEN Industries can help with your HVAC renovation projects.

Signs of Aging Ductwork

There are a few ways to assess the health of your project’s ductwork. Here are some of the most common signs that it may need replaced. ZEN Industries recommends that ductwork be replaced in commercial buildings when they are experiencing problems like these.

Airflow and Temperature Inconsistencies

When some rooms of a building are different temperatures or have less airflow than others, this may be a sign that the HVAC duct will need replaced.

Reduced airflow may be an indication that something is blocking the duct near that area, or that the duct has been bent, crushed, or otherwise damaged between the takeoff and the supply vent. Built up debris, animal activity, leaks, or physically damaged components can all interrupt the delivery of conditioned air, contributing to some areas being to hot while others are uncomfortably cold.

Physical Damage

Damaged DuctworkOne of the most obvious signs that a commercial building’s ductwork may need replaced is physical damage to the ductwork itself.

Over time, ductwork can become damaged by rust or corrosion, which could cause air leaks if left unattended. Pests such as mice can also damage ductwork from chewing on insulation, leading to energy loss from uninsulated sections of duct.

Improperly installed or older ductwork can come apart, separating at loose joints or where tape has peeled away. Other forces can also bend, crush, or block airflow through the ductwork, leading to restricted airflow in affected areas. This happens when building work and renovations are done over the years, as well as when other aging systems put weight or shift against aging ductwork.

Higher Energy Bills

Another common sign that ductwork may need replaced is an increase in energy bills. Higher energy costs have a variety of causes, including damaged ductwork or blockages within the ductwork. Any time the flow of conditioned air is impeded, the system works longer and harder than necessary.

It is also possible that higher energy costs are the result of ductwork that passes through an uninsulated space within the building. Ducts installed in uninsulated spaces can cost building owners significantly more in energy expenses, since the air outside the ductwork can affect the temperature of the air inside of it.

Hot air around uninsulated ductwork can warm up the cooler air inside the duct during the summer, and the same is true for cold air around ducts transporting heated air in the winter. Having ductwork pass through an uninsulated section of the building wastes valuable energy that could otherwise be carried to the appropriate sections of the building.

The Advance of Time

Rotted HVAC DuctworkMost HVAC systems begin to show signs of physical damage after fifteen to twenty years of operation.

Older HVAC ducts are less energy efficient, and exposed sections of ductwork can look unsightly if they have been affected by rust or corrosion damage.

Older HVAC systems in commercial buildings are often much less energy efficient than their modern counterparts, even if the ductwork itself is not damaged. In older buildings, the cavities between joists were often used as substitutes for proper ductwork at the time of construction.

This method is not very energy efficient, as a large amount of air from the HVAC system is lost due to leaks when the air is not conducted properly. Installing proper ductwork in these areas ensures efficient airflow and minimizes energy loss from heated or cooled air that would otherwise dissipate.
