Ductwork serves as the circulatory system of your home or building. But those intricate elements of ductwork you see above your property aren’t something that HVAC experts throw together without thought. Proper ductwork design is responsible for the efficient distribution of heated or cooled air throughout the space, ensuring comfort in every corner. However, several common mistakes made during the ductwork design process can drastically impact the overall performance and efficiency of the HVAC system. Fortunately, experts like us at JC & JC HVAC Mechanical Contractors have the knowledge and experience to prevent these pitfalls. We’ll highlight some of the biggest mistakes and how true experts can avoid them.
Failing to Properly Seal the Ducts
The first mistake we often encounter in ductwork design is a failure to seal the ducts properly. This seemingly small oversight can lead to significant issues. Unsealed or poorly sealed ducts can result in substantial air leakage, which means that the conditioned air — whether heated or cooled — doesn’t reach its intended destination. Instead, it seeps into spaces where it’s not needed, like between walls or in the attic.
The consequences of this are twofold. Firstly, the HVAC system has to work overtime to compensate for the lost air, leading to increased energy consumption and higher utility bills. Secondly, the overall comfort level within your home or building decreases due to inconsistent temperatures.
Not Getting the Right Size
Another frequent error is not getting the right size of ductwork for the specific needs of the space. The size of the ducts plays a critical role in the amount of air that can be distributed throughout your home or building. If the ducts are too small, they can restrict airflow, causing your HVAC system to work harder than necessary. This reduces efficiency but also accelerates wear and tear on the system.
Conversely, if the ducts are too large, they may not provide enough air pressure to distribute the conditioned air effectively. This can result in uneven temperatures and comfort levels throughout your space. Poor ductwork practices can also include ductwork that’s too big for a smaller space, leading to inefficient heating or cooling.
We use precise calculations based on the size and layout of your space, as well as the capacity of your HVAC system, to determine the optimal duct size. This delivers balanced airflow, optimal system performance, and energy efficiency.
Poor Insulation of the Ductwork
The insulation of the ductwork is another critical factor often overlooked during the design process. Without proper insulation, heat can escape from the ductwork during winter, and cool air can escape during summer. This means your HVAC system has to work harder to maintain the desired temperature, leading to increased energy consumption. By properly insulating the ductwork, your HVAC contractors can minimize thermal loss, ensuring that more of the conditioned air reaches its intended destination.
Excessive Long Runs of Ductwork
Another common mistake is creating ductwork designs with excessively long runs. The longer the duct runs, the more energy it requires to push air through them. This can decrease the efficiency of your HVAC system and increase your energy costs. This requires careful consideration and is especially important in large commercial facilities that need plenty of airflow.
Placing Ductwork in Poor Positions
The placement of ductwork can significantly impact the efficiency and effectiveness of your HVAC system. Placing ductwork in unconditioned spaces, such as attics or crawlspaces, can lead to significant energy loss due to temperature differences. By avoiding unconditioned spaces and considering factors like sunlight exposure and outdoor temperatures, expert HVAC teams can make sure you get the best bang for your buck.
