Ducts have a maximum lifespan of 20 to 25 years, but they start to deteriorate at 15 years old, significantly reducing the efficiency of the HVAC system. This is why experts suggest replacing ducts around every 15 years. The materials used to make ducts, such as fiberglass and plastic, are prone to wear and tear over time, which can have a negative effect on the performance of the air conditioning system and indoor air quality. If you observe that your ducts are badly damaged, it's best to call a professional for a complete duct replacement project.
Like all HVAC equipment, air ducts can become worn out and break down, so it's important to have your ducts inspected and possibly replaced every 10 years or so. If you're looking for a new HVAC system, local companies like Fox Family Heating and Air can provide estimates. It's also essential to keep in mind that air duct seals, joints and connections are vulnerable to deterioration over time. If there are holes in the ducts, you'll also hear loud noises when air moves through the ducts.
You can always check the air filter first and change it if necessary (a clogged air filter will restrict cooling performance). To find out if replacing the ducts is right for your home's comfort needs or to schedule a duct cleaning or inspection, contact AAA Heating and Cooling. A qualified HVAC technician will decide if a repair or a full duct replacement would be more beneficial for you and make expert recommendations accordingly.
