Types of Ducts We Seal

Signs of Leaking or Damaged Ducts
When the duct system develops leaks, it can cause problems throughout the entire HVAC setup. Spotting the signs early can help fix issues before they worsen and restore overall system performance. Here are some common signs that the ductwork in a property 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.
