When Should You Consider Replacing the Ductwork in Your Home?

replacing ductwork

Let’s face it. It’s easy to ignore the ductwork in your Metro-East home. Out of sight is out of mind. But even this hidden hero in your home has a finite lifespan. Aging ductwork can lead to airflow problems, poor HVAC performance, or higher energy bills. Fortunately, Ernst Heating & Cooling can help you determine if it’s time for a ductwork overhaul.

Although you may think ductwork is just a convenient way of directing air around your home, those joints, seals, and seams are always working. When warm air rushes through them in the winter months, the ductwork will expand—the ductwork contracts when your HVAC system switches to A/C in the summer. The movement can be minuscule, but it can be enough to cause leaks in the seams. These small changes can reduce airflow and put an unnecessary burden on your HVAC unit. Condensation in the summer may lead to rust, especially if your ductwork isn’t insulated.

When is it time to consider new ductwork? If you notice one or more of these warning signs below, contact Ernst Heating & Cooling to learn about ductwork replacement or renovation.

Uneven cooling or heating

Have you noticed that certain rooms in your home just haven’t gotten warm this winter? Your ductwork may not be moving air efficiently, resulting in cold spots in the winter and warm spots in the summer months. A leaky air duct is losing air before it has a chance to make the room comfortable. Who wants that?


Yes, you’re going to hear a noise as your HVAC system works. A little noise is normal. Whistling or rattling noises suggest damage inside the ductwork. Constant rattling sounds mean the HVAC ductwork is vibrating more than usual.

Mold and odor

Do you notice a damp smell in your home? Condensation within your ductwork can lead to mold and mildew formation. This not only adds an unpleasant odor, but it can also cause health issues for you and your family. Mold may also damage your furniture and other possessions.

Noticeable dents and punctures

When was the last time you looked at your ductwork? Of course, there’s no way you can see inside your home’s walls. But if you have a basement, take a moment to eyeball the visible ductwork. If you see any dents or punctures, contact Ernst Heating & Cooling now for a thorough inspection.

Higher energy bills

Many variables can contribute to higher energy bills, including temperature swings, higher energy costs, or even a clogged air filter. Fault ductwork may also be the culprit. If your home’s ductwork has sprung a leak, you’re paying for air that never reaches its destination.

A duct system replacement or renovation can keep your family comfortable and save you money over the long term.
