Signs your Ductwork Needs to be Repaired or Replaced

Research shows that almost 25% of the air in your Heating, Cooling, and Ventilation System (HVAC) ducts go astray due to potential leakages and loosely fixed vents. It causes hundreds of dollars of extra energy bills every year. So, the solution to this issue is to either upgrade your ductwork or hire Air Duct Repair and Replacement Services in your vicinity.


People who own HVAC systems underestimate the importance of ducts, which can be a costly mistake. The reason is that ducts play a significant role in the functioning of an HVAC system by pulling air from various parts of the surroundings and then circulating the heated or cooled air. 

You must understand that if your system has holes, it will weaken the air pressure. It makes the system work harder, burdening your energy notices. HVAC ducts made out of fiberglass and plastic can last up to 10 or 15 years. 

Spending on air duct repair and replacement will save you from high bills. So, experts recommend observing the condition of your ducts before it causes significant damage. 

If your HVAC system is not performing efficiently, you must consider approaching an air duct cleaning or repair service to get it fixed. It will help you avoid complex problems. Likewise, damaged ducts can be a source of toxic air, so timely duct maintenance is essential. Air duct cleaning is crucial for your good health and clean surroundings. 


1. HVAC System Produces Annoying Sounds 

Although HVAC systems emit a sound when they function, an annoying, rattling or unusual sound can be alarming. Even excess vibration of the system while heating or cooling the space can also be a sign of air duct repair and replacement. Duct joints are thru of thin plastic or fiberglass, so you may hear a rattling or shrilling sound when they are damaged. 

2. Unexpected High Energy Bills

Typically, 20% of the air escapes when the HVAC system functions, but it will reflect in your energy bills if the amount exceeds that limit. It means that your HVAC system is not working up to the mark and has to devote extra energy to fulfill the requirements. You must get your ducts inspected if you have unexpectedly high-energy beaks. 

3. Jagged Heating or Cooling 

If your HVAC system is functioning inefficiently, you may notice that one or two rooms in your building may not be adequately warmed or cooled. A reason can be broken ductwork, as it may not be circulating air efficiently. This issue can be quite easily detected using an indoor thermometer. 

4. Dusty Surroundings 

Dust is simply a nuisance when it exceeds a specific limit. It connects to many serious issues, especially for people with underlined health conditions. If you observe too much dust in your indoor surroundings, it is a possibility that it may cause due to damaged ductwork. Any leakage in the ducts may allow dust from the outside to penetrate the inside. The dust carries through the vents to the indoor surroundings. Too much dust can be a cause of cardiovascular diseases among people. 

5. Mold and Mildew Growth 

Likewise, mold and mildew growth can also trigger due to badly connected or poorly shielded ductwork. Mold or mildew tend to grow due to differences in temperatures inside and outside of the air ducts. For instance, when warning air from outside penetrates cold HVAC ducts, condensation occurs, and when this happens regularly, there is a chance that mold or mildew develops. An unpleasant smell when the HVAC system indicates mold growth can cause serious health issues and damage to furniture objects.  

6. Pest Infestations

While there is a risk of mildew growth due to damaged ductwork, it may also cause pest invasions. Any leakages in the HVAC ducts may allow vermin to enter and establish colonies. It is also a significant cause of health ailments. 

We can detect Pest infestations through an unpleasant odor, microbial air, and unusual sounds while the HVAC system works. Apart from this, HVAC may also get impaired if pests cause logjams within the ductwork. So, experts recommend that you carry out regular inspections of your HVAC systems. If there are any usual signs, you should contact a certified technician from a professional service. 

7. Respiratory Issues

If your home members show symptoms like frequent sneezing, allergic reactions, or strange coughs, which cause is not apparent. A possibility might be that your ductwork might be verminous with allergen particles like pollen or dust fragments. 

Pollen and dust can be very harmful to people suffering from respiratory disorders. So, you must frequently examine your ductwork for any damages before your indoor air quality becomes unbearable. 

8. Wreckages Around HVAC Vents

By default, the vents come with the purpose to release cold or warm air within your house. But if the air is too murky, it will surely leave symbols on the ducts over time. The debris forms due to the accumulation of dirt, grime, fur, pet remnants, or insect relics. It is an alarming issue and needs professional treatment right away; otherwise, it may cause severe health conditions. 

9. Tousled Ducts

If the air ducts are tousled or twisted, it hinders the HVAC system’s proper functioning resulting in high energy bills. Now the question is, how do the ducts get tangled? An encounter with a heavy item such as a rock or tree branch causes the ducts to twist and hinder airflow. Sometimes, the ducts also develop leakages and can be detected from exposed areas of the HVAC system. 

10. Old HVAC Air Ducts 

If your HVAC ductwork is too old, then it may also need repair. Even if an old HVAC system’s ductwork appears to expect, it may have asbestos insulation (a cancer-causing material), so getting your ductwork inspected immediately is crucial. 

Now, the duct installation procedures have advanced compared to previous years. More effective and benign material is in use for the HVAC ductwork installation. So, replacing the ductwork is essential; otherwise, your health might be at risk.
