How Can I Tell If My Air Ducts Need To Be Sealed?

Signs Your Air Ducts May Need Sealing

Leaky ductwork is a common issue in many homes and can lead to comfort problems and higher energy costs. The challenge is that duct leaks are often hidden, so you have to rely on symptoms.

Here are the most common signs your ducts may need sealing:

• Rooms that are too hot or too cold compared to others
• Higher energy bills without a clear reason
• Weak airflow coming from vents
• Excess dust or poor indoor air quality
• Your HVAC system runs longer than usual to reach the set temperature

In many homes, especially in the Texas Hill Country where ductwork runs through hot attics, air can escape before it ever reaches your living space.

The most accurate way to confirm duct leaks is through a professional inspection or airflow test. This helps identify where air is being lost and how much it’s affecting your system.
