Ducts placed out of sight often slip out of our minds. However, this doesn’t mean that they are not subjected to deterioration. Although a duct can serve your home for about a decade, its performance can plummet before due time because of neglect or improper installation. On the other hand, if you repair and maintain your HVAC ducts, they can attend to your needs for a fair amount of time. Hence, as a general rule of thumb, you should try to repair any faults as soon as possible. Therefore, you must recognize some telltale signs of HVAC air duct repair.

Creation Of Hot Or Cold Spot:

Your HVAC air ducts serve an important role in circulating hot and cold air around your house. If the air duct’s performance is under par, you can expect a hindrance in the airflow. As a result, air pressure out of air vents may drop in some places due to uneven circulation. Another immediate effect of poor airflow and uneven circulation is the creation of hot and cold spots. Hot or cold spots form when the heating or cooling is sporadic; therefore, some rooms may experience exceptional cooling while others may not.

Dusty Or Moldy Air Vents:

It’s hard to see what’s going on in your HVAC ducts. However, you can get a sneak peek through air vents and air registers. Therefore, if you see a major dust buildup or some mold growing, it’s safe to assume that most of the duct’s interior will be like that. This will eventually translate to low air quality and poor airflow. Hence, you might need to call in an HVAC specialist that may inspect your ducts and help you clean them.

Unusual Sounds From Your Air Ducts:

Can you recall the sound of air whooshing out from a small leak? You might hear a similar sound near your HVAC air ducts, indicating a structural leak. You may hear loud rattling or shaking sounds because of the loose-fitting of components. Most of these strange sounds are continuous and stay there when you are operating your HVAC unit. Ignoring such sound may be detrimental to the health of your HVAC system because it can lead to further wear and tear. Hence, call your HVAC specialist when you hear such sounds.

High Electricity Bills:

When your air ducts are under the weather, your HVAC unit feels the storm. Due to restrained airflow and poor outcomes, the HVAC unit has to work overtime to maintain a similar comfort level. Now, we all know what that means, high electricity bills! However, that’s not all; due to deteriorating air ducts, your HVAC unit parts might undergo faster wear and tear. Consequently, you would have to bear additional repair or replacement costs.


Ill-maintained or faulty air ducts will eventually open up a pandora of problems. Hence, to avoid all that inconvenience, regular HVAC maintenance is a must.
