Similar to an AC unit, air ducts can last anywhere from 10-15 years with proper care and maintenance. It is, however, important to note that over time, air duct seals, joints, and seams are vulnerable to deterioration. This deterioration can cause a litany of problems for your HVAC systems, including increased energy costs, poor performance, and overall discomfort in the home. If you’re air ducts are at least 10 years old, it is time to have them inspected and possibly replaced by a professional.

Poor Airflow

If you start to notice that airflow in your home’s vents is decreased or not operation at optimal levels, it might be a sign your HVAC system is functioning properly. When ductwork is damaged, old, filthy, or clogged, your home is likely to suffer the consequences – high energy bills and discomfort due to lack of being able to regulate air temperatures. If you notice your HVAC system’s airflow struggling or depleting, it may be time for a replacement.

Mold and Odors

A sure sign that all is not well with your air ducts in your HVAC system is when bad odors start emanating through them. In the past, we’ve discussed what is causing that smell in your HVAC, and we feel compelled to bring it up again here. Mold is always a severe problem, especially if it gets into your ductwork. When mold penetrates your ductwork, harmful (and potentially fatal) mold spores are spread throughout your house. If you HVAC systems emits a foul smell, and you fear that mold may be the cause, contact a mold remediation expert immediately.

Dents, Punctures, and Noisy Operation
