Your ductwork is likely out of sight, but that doesn’t mean you shouldn’t give a thought to it now and then. The fact is, ducts, like everything else in your home, can age and deteriorate, requiring repair or replacement.
Signs of Old Ductwork
High energy bills. If your energy bills are mounting, the cause may be aging ductwork. Duct segments that come loose or develop holes over time lose conditioned air. If they are in unconditioned spaces, this could be costly. The ducts should be repaired; if they are more than 15 years old, they may need to be replaced.
Aging ducts. If your ductwork is 10-15 years old, take a good look at it now and then. Some signs of aging may not be repairable. For instance, rust or corrosion of the metals can mean it’s time to replace the ductwork altogether.
Unbalanced airflow. Your airflow should be even throughout your home. If it seems temperatures are uneven from room to room,, then it might be time to redo the ductwork. Ductwork may collapse or become blocked, leading to temperature differences and uneven airflow.
Poor indoor air quality. Aging or compromised ductwork may be allowing pollutants such as mold, mildew, pollen and dust into the home’s air supply. If repairs to the ductwork appear likely to be too extensive, then it may be time to replace it.
Humidity. Moisture or excess humidity is another concern. Damaged ducts can allow moisture to be drawn into the home’s supply air, raising humidity and making it more challenging — and more expensive — to cool your home in the summer.
If your ducts are located in a space where it’s difficult to examine them, ask your HVAC consultant about a duct blower test. Using a blower fan to pressurize ducts, the consultant will determine if the air from the HVAC blower is sufficient to maintain pressure throughout the ducts.
