When Is The Time To Replace Your Air Ducts

It’s important to remember that air ducts are a critical part of your home and office ventilation. With their absence, your HVAC unit wouldn’t be able to take the fresh and clean air from one room to another.

Therefore, deterioration can lead to many complications to your HVAC systems, such as the high consumption of energy, low system efficiency, and general discomfort within your home and office. With the latest models designed to energy efficiency, you may be able to avoid additional expenses through a timely upgrade.


Poor System Airflow

     When you feel the cool air throughout your room or office, but you have observed that your unit doesn’t release air out the way it used to. This may be due some factors  that include issues with the compressor or broken vents. Though you may hire a professional technician to do the repair, it can be quite costly depending on the maturity of your system and the degree of the issue. When your ductwork is defective, old, dirty, or congested in any way, your home or office will have to put up with the consequences such as inflated electric bills and inconvenience. 

 Inconsistent Heating or Cooling Performance

     When some areas in your home or office are too hot, while the others are too cold, then there might be an issue that needs to be fixed with your HVAC ducts. There are a number of factors that can impair your system and make it difficult to chill your home or office. You can always try inspecting your air filter first and replacing it when necessary. A clogged air filter will drop cooling performance. If that doesn’t improve your unit, then it’s high time to call for a licensed technician to diagnose your ductwork.


Debris and Punctures around the Vents

     The presence of scratches and defects can drastically hold back the efficiency of your cooling system. If you can clearly see punctures in your ductwork, contact a professional technician to diagnose the issue. A HVAC technician will identify whether you would be advisable to do repair or opt for a complete duct replacement and get some professional recommendations accordingly. The debris may be the result of the buildup of dusts, fragments, pet hair, or even pests.


Molds and  Odors in the Ducts

     As time passes by, moisture in your home or office air ducts can form molds. This problem can also be a result of poorly installed or insulated ducts. Mold and mildew accumulate as a result of the difference between internal and external temperatures of the HVAC ductwork. When this occurs, your HVAC system works but spreads mold bacteria and bad smells throughout your home or office. From chronic allergies to even potentially severe medical complications, mold in your ductwork can become an item laundry list of problems. If your HVAC system releases a foul odor and worry your ducts may contain molds, seek professional assistance immediately. While duct cleaning can help, a complete replacement is always the best thing to do.

     When you start hearing a lot of noise from your heating or cooling system, the ductwork could be truncated. These unpleasant sounds often indicate a serious problem  – such as a belt moving out of place or damaged motor bearings – that could result in a costly repair or need for replacement if not fixed immediately. If you regularly hear whirring sounds or if the HVAC ductwork is wobbling too much when heating or cooling, your house or office, then you need to inspect the ducts. Remember that the ducts are installed with plastic or fiberglass joints. If these joints get busted, you will often hear whirring sounds. Pay attention to this noise before it gets worse.


Improper Duct and Design

If your ductwork was not installed properly for one reason or another, replacement is a must. Unfit design or installation is one of leading causes of residential power outages. Despite installing a brand new AC unit that suits your place, poor ductwork reduces optimal efficiency and comfort is almost impossible. Improper duct design can disrupt its proper function even with the right HVAC equipment size.

These leaks allow cooled air to get out of the ductwork, and dust and dirt to penetrate. They allow quantities of contaminants and pollutants to spread to your home or office. Dust mites can cause asthma in children and other high risk individuals.
