Signs Your Ducts Are Leaking and Need Repair
When your ductwork develops leaks, it can cause problems throughout your entire HVAC system. Spotting the signs early can help you fix the issues before they get worse and restore your system’s performance. Here are some common signs that your ductwork may have leaks:
- Uneven Heating or Cooling: Some rooms feel too hot or too cold compared to others.
- High Energy Bills: Your HVAC system works harder, causing a spike in energy costs.
- Poor Airflow: Weak or inconsistent airflow from vents can indicate leaks.
- Unusual Noises: Whistling or hissing sounds near ducts can mean air is getting out.
- Musty or Moldy Smells: Leaks can let moisture in, leading to mold growth and bad odors.
- Dust Buildup: Excess dust around vents or in rooms may mean leaks are letting dirt in.
