Signs You Need Air Duct Sealing

Signs You Need Air Duct Sealing

Ensure maximum HVAC efficiency and indoor comfort with properly sealed ductwork. Even small leaks or gaps in your ducts can waste energy, reduce airflow, and affect air quality—costing you money and comfort every month.

Why Duct Sealing Matters

According to the U.S. Office of Energy Efficiency and Renewable Energy, up to 40% of a building’s energy use goes toward heating and cooling. Leaky or poorly connected ducts can cause significant energy loss, forcing your HVAC system to work harder and shortening its lifespan.

Common Causes of Duct Leaks

• Improper installation or loose connections
• Damage from rodents, moisture, or physical impact
• Shifts during maintenance or attic work
• Normal wear over time from heat and vibration

Warning Signs of Leaky or Broken Ducts

• Noticeable dust buildup or poor indoor air quality
• Uneven temperatures—hot and cold spots throughout the home
• Rising energy bills despite normal usage

What to Do If You Suspect a Ductwork Issue

A professional HVAC technician should inspect every section of your ductwork—including joints, seals, and insulation. Damaged or missing sections must be replaced immediately, and all seams resealed with proper materials such as mastic or metal tape. Avoid using standard duct tape, which deteriorates quickly from moisture and heat.

Once repairs and sealing are complete, a follow-up air pressure test can verify improved efficiency and airflow consistency throughout your home or building.

• Lower energy bills and improved system efficiency
• Better airflow and consistent temperatures
• Cleaner, healthier indoor air quality
