Your air ducts are the lungs of your home’s HVAC system—quietly delivering warm or cool air to every room. But like any system that’s hidden behind walls and ceilings, it’s easy to forget that air ducts need attention too. At Go Air Ducts, we conduct thorough inspections that often reveal underlying issues most homeowners aren’t aware of. These problems can compromise your HVAC system’s efficiency, increase energy bills, and affect your indoor air quality.
Let’s break down the most common air duct problems found during professional inspections and explain why addressing them early is so important.
1. Dust and Debris Buildup
One of the most frequent findings in duct inspections is excessive dust and debris. Over time, dirt, pollen, pet dander, and even construction dust can accumulate inside your ductwork. As air flows through the system, these particles can circulate through your home, aggravating allergies, triggering asthma, and reducing indoor air quality.
Excessive buildup can also restrict airflow, forcing your HVAC system to work harder than necessary, which leads to higher energy usage and utility bills.
2. Mold and Mildew Growth
In humid environments or systems with condensation problems, we often discover mold or mildew inside the ductwork. This is particularly common near evaporator coils or in areas where ducts pass through unconditioned spaces like attics or crawl spaces.
Mold spores in your HVAC system can be a serious health concern, especially for people with allergies, respiratory conditions, or weakened immune systems. A musty smell in your home could be the first sign of a hidden mold issue.
3. Leaks and Disconnected Ducts
Leaky ductwork is more common than most homeowners realize. During inspections, we often find cracks, loose joints, or sections of ductwork that have completely disconnected—especially in older systems or poorly installed ones.
Leaky ducts can waste up to 30% of your conditioned air, meaning you’re paying to heat or cool spaces that aren’t getting that airflow. Not only does this reduce comfort in your living areas, but it also puts extra strain on your HVAC system.
4. Poor Insulation or Uninsulated Ducts
Ducts that run through attics, basements, or crawl spaces should be properly insulated to prevent heat loss or gain. During inspections, we frequently find ducts that are under-insulated or not insulated at all.
This causes cooled or heated air to lose its temperature before reaching the vents, leading to uneven room temperatures and inefficient energy use. Insulation upgrades can drastically improve system performance and comfort.
5. Pest Infestations
Rodents, insects, and even birds sometimes find their way into ductwork, particularly if there are gaps or broken seals. During inspections, we sometimes discover droppings, nests, or even live pests inside the ducts.
This isn’t just a cleanliness issue—it can be a health hazard. Pest activity in ducts can contaminate the air and damage duct materials, leading to poor air quality and costly repairs.
6. Improper Duct Sizing or Layout
Sometimes, the root problem isn’t damage—it’s poor design. During inspections, we occasionally encounter ducts that are too small or poorly routed to handle the demands of the HVAC system. This can result in rooms that never reach the right temperature or systems that cycle on and off constantly.
Correcting these design flaws improves airflow and balances the distribution of air throughout the home, increasing both efficiency and comfort.
7. Blocked or Closed Vents
It’s not uncommon to find blocked vents or closed dampers during a duct inspection. Homeowners might unknowingly obstruct vents with furniture or decorations, or close them in an attempt to redirect airflow. While it may seem harmless, this can lead to imbalanced pressure in the system, reduced efficiency, and even duct damage over time.
Why Regular Duct Inspections Matter
Most of the problems listed above are silent—but their effects are anything but. You might notice symptoms like rising energy bills, uneven temperatures, musty odors, or more frequent allergy symptoms, without realizing that your ducts are the source.
Routine inspections by a qualified team like Go Air Ducts help catch issues before they become major problems. We provide visual assessments, airflow testing, and if needed, advanced diagnostics using cameras or pressure readings to detect leaks and blockages.
