Common Issues With Residential Ductwork & How To Fix Them


When it comes to residential dwellings, ductwork is one of the most important components for a healthy and efficient HVAC system. Problems with your ductwork can lead to inefficient air distribution, high energy costs, and discomfort in your home. If you're dealing with any of these issues, it's important to understand the common issues with residential ductwork and how to fix them.

Leaky Ducts

One of the most common issues with residential ductwork is leaky ducts. Over time, your ducts will deteriorate and small cracks can form, which can lead to significant energy losses. To fix leaky ducts, you need to patch any cracks or tears and seal the seams with mastic or foil-backed tape.

Airflow Imbalances

Another issue that can come up with residential ductwork is airflow imbalances. This can be caused by improperly sized ducts, unevenly distributed air registers, or improperly installed ducts. To fix this problem, you first need to determine the cause of the imbalance, and then adjust the size of the ducts, add/remove air registers, or repositioning the ducts in the system.


Proper insulation around your ductwork is essential for efficient energy performance. Improperly insulated ducts can cause significant energy losses and hot/cold spots throughout your home. To fix this issue, you need to ensure that the insulation is in the right places and that it's the appropriate size and material.

Ductwork Cleaning

Cleaning your ducts is essential to ensure that they don't become clogged with dust and debris. A clogged duct can reduce the flow of air and put additional strain on your HVAC system. To clean your ducts, you need to hire a professional duct cleaning company.

By understanding the common issues with residential ductwork and how to fix them, you can help ensure that your HVAC system is functioning properly and that your home is comfortable. If you're dealing with any of these issues, make sure to take steps to address them quick, to avoid further damages and extra costs.
