Your ductwork works hard behind the scenes, but when it starts to wear out, it can cause all sorts of headaches — higher bills, uneven temperatures, and a lot more dust than usual. One Hour Heating & Air Conditioning® is here to guide you through the common signs it's time to replace your ductwork.

How Long Do Air Ducts Last?

With proper installation and maintenance, most ductwork systems can last between 15 to 25 years. However, several factors can affect their life span, including the quality of materials, environmental conditions, and the presence of any initial installation flaws. Regular inspections and annual cleaning can help identify potential issues early and extend the life of your ductwork. One Hour® provides professional air duct services so your HVAC system runs smoothly.

Key Warning Signs You Need New Ductwork

Even with a long life span, ductwork can still develop problems that affect the operation of your HVAC system. Watch out for these indicators that it's time to replace your air ducts: 

Cracks, Holes, Rust, and Other Visible Damage

Take a peek at your ducts. If you spot visible damage like cracks, holes, or rust patches, your system could be leaking precious air. That means your HVAC has to work harder to keep your home comfortable.

Increased Energy Bills 

If your energy bills are creeping up with no clear explanation, leaky ducts might be the culprit. When conditioned air escapes through gaps, your system compensates by working overtime — and your utility bill pays the price. Replacing faulty ducts can bring those costs back down.

Uneven Heating or Cooling

One room feels like a sauna, while the other one feels like a fridge. Inconsistent temperatures are a classic sign of ductwork issues. When ducts are damaged, air can struggle to reach certain areas, leaving your home out of balance.

Strange Noises

Ducts should not be making a scene. If you hear rattling, whistling, or banging noises when you switch your system on, it could signal loose or damaged sections. While some issues can be repaired, ongoing noise might signal time for a full replacement.

Can You Replace Ductwork at Home?

Replacing ductwork at home is complicated. While some minor ductwork repairs can be DIY, replacing an entire system requires specialized knowledge and equipment. For safe and effective ductwork replacement, it's best to contact the professionals at One Hour Heating & Air Conditioning®. In between annual cleanings and inspections, there are a few tips you can use to keep ducts clean and running smoothly, such as:

  • Clear all supply and return vents  — move any furniture, debris, or other items that block airflow.
  • Replace your air filter regularly, using the correct size for your system.
  • Check for unusual whistling or air noises near return vents.
  • Keep indoor humidity between 30-50% for optimal comfort.
  • Maintain proper ventilation in kitchens and bathrooms by keeping exhaust fans clear and working.
