As an HVAC expert, I have encountered numerous cases where homeowners are hesitant to replace their ductwork when replacing their air conditioner. However, from my experience, I can confidently say that replacing ducts is crucial for optimal efficiency and air quality. Over time, the duct system ages just like any other equipment. The gaskets, seals, and joints can weaken and malfunction, leading to reduced comfort and increased energy costs. This is why it is recommended to replace ducts every 10 years to ensure high indoor air quality. When replacing an air conditioner, many contractors will recommend replacing the ductwork as well.
This is because a new AC unit paired with old ducts can result in uneven distribution of air and decreased efficiency. By installing new ductwork, you can ensure that the air is evenly distributed throughout your home, providing maximum comfort. It is important to note that not all cases require a complete replacement of ductwork. A trained HVAC technician will assess the condition of your ducts and make expert recommendations accordingly. However, it is still necessary to check and potentially replace your ducts every 10 years or so. Since most people replace their air conditioning units every 15 years, it is best to consider replacing the ductwork at the same time.
This will not only ensure superior performance but also save you from the hassle of having to replace your ducts separately in a few years. In conclusion, as an HVAC expert, I highly recommend replacing your ductwork when replacing your AC unit. It may seem like an additional expense at first, but in the long run, it will save you from discomfort and high energy costs. Trust me, investing in new ductwork is worth it for the sake of your indoor air quality and overall comfort.
