Can My Ductwork Go Bad? What Metrics to Consider?

There is a lot of misconception surrounding ductwork, whether it can go bad over time or if it might last a lifetime. As one of Burnaby’s air duct cleaning teams, the team from Air Duct Cleaning Services wanted to clear a few things up for you here.

So, here is all the information you need to know about whether or not your ductwork can go bad over time.

Time is a Factor

Many HVAC repair professionals and heating and cooling experts will tell you that if you haven’t replaced your ductwork in around 15 years or more, it likely needs to be updated. This is especially true if you’re considering investing in a new heating and cooling unit. However, does this mean that your air ducts are “bad” and falling apart? Not likely. But there is a concern that outdated ducts can be much harder to maintain and don’t always work as well.

It’s a Matter of Efficiency

When HVAC professionals talk about having bad ducts, what they usually mean is that they’re inefficient, and updating them will benefit you in a number of ways. They’ll be easier to clean and maintain, you’ll have fewer air leaks, and they’ll likely be able to distribute hot and cold air throughout your property much more quickly and effectively. Ductwork shifts and moves due to the thermal expression and heat extremes. This eventually leads to ductwork that’s poorly connected and in some cases, it can become disconnected completely in parts, causing spikes in your energy costs and a less comfortable temperature in your home. It can also cause your HVAC system to work overtime.

Key Metrics to Consider

If you’re wondering whether your ductwork is going bad, here are some metrics and signs to keep in mind:

1. Age of the system – If your ducts are 15–20 years old, it may be time for a professional inspection.

2. Energy bills – Unexplained spikes in heating or cooling costs often point to leaky or inefficient ducts.

3. Airflow strength – Weak airflow in certain rooms can mean blockages or disconnected sections.

4. Indoor air quality – Excessive dust, musty odors, or allergy flare-ups may indicate dirty or damaged ducts.

5. Noise levels – Whistling or rattling sounds when your HVAC runs can be a sign of leaks or loose connections.

These factors don’t always mean your ductwork needs replacing, but they do suggest it deserves a closer look.

Maintenance Goes a Long Way

Fortunately, ductwork doesn’t automatically need replacing just because it’s older. With proper cleaning and maintenance, ducts can continue functioning effectively for years. Regular duct cleaning helps remove dust and debris that strain your HVAC system and circulate pollutants indoors.

It’s also important to schedule routine HVAC inspections. A professional can test for air leaks, check connections, and recommend improvements such as sealing or insulating ducts—solutions that are often more affordable than full replacement.
