If your ducts are more than a decade old, it's time to think about replacing them. Poorly connected ducts or those with multiple holes can cause air pressure to be lost, making your HVAC system work harder and increasing your energy bill. Ducts are usually made from a combination of materials such as fiberglass and plastic, and they are designed to last 10 to 15 years on average. Like any other equipment, the duct system also ages over time. Gaskets, seals, and gaskets can weaken and malfunction, reducing comfort levels and increasing energy costs.
To avoid these problems, it is recommended to replace the ducts every 10 years in order to maintain good indoor air quality. When it comes to cleaning or replacing ducts, it is important to hire an experienced professional. The National Association of Air Duct Cleaners suggests employing a professional to clean your ducts every three to five years, while the EPA says you can usually skip cleanings unless you observe visible signs of mold or excessive dust. If there are severe outgrowths of mold, replacement may be necessary, particularly if the ducts have been rusted.
