Signs That Your Air Ducts Need to be Replaced

There are several key indicators that your property may require air duct replacement, including:

  • Air leaks: Gaps or holes in your ductwork can cause air to escape, reducing efficiency and comfort.
  • Dirty air ducts: Over time, dust, pests, and debris can accumulate in your ducts, leading to poor air quality.
  • Mold growth: Moisture can enter ducts, creating a breeding ground for mold, which can cause health problems.

Frequently Asked Questions About
Air Duct Replacement in Virginia

Knowing when your air duct system only requires simple repairs can save you time and money. Signs to look out for when a repair is needed include leaky air ducts, poorly insulated systems or imbalanced ductwork. Eventually, all air ducts will need replacement. The age of your air ducts and damage caused by smoke, water or rust are the most common causes for air duct system replacements.

If you hear strange sounds from your ducts, you could have leaky air ducts. Another obvious sign of air duct leakage is high energy bills. When air escapes out of the ducts, your system wastes energy, producing more hot or cold air. Your leaky ducts will likely result in a spike in your energy bill. It may also cause your system to run frequently.

Duct sealing lasts anywhere from 10 to 15 years. If you use quality materials and have a professional handle the duct sealing, it could last closer to the end of that range. However, most flex duct systems only last about 15 years and no amount of care will make them last longer. You should ask your HVAC technician about the length of time your duct sealing will last.
