Benefits of Air Duct Sealing and Coating
Here’s why properly sealing and coating your air ducts is essential for a healthier, more efficient home—and why it shouldn’t be overlooked during HVAC maintenance:
Energy Efficiency
Sealed ducts keep heated or cooled air inside. This helps your heating and cooling systems work better without extra effort.
Cost Savings
Many homes lose lots of air through leaks. Fixing these leaks cuts down on energy waste and lowers your monthly bills.
Improved Comfort
When air flows right, every room feels just right. No more cold spots or uneven temps around the house.
Healthier Indoor Environment
Clean, sealed ducts stop dust and allergens from spreading inside your home.


Healthier Homes Through Clean Air Ducts
Clean air ducts help keep your home healthy. Dust, pollen, and other environmental allergens can pile up inside your ducts over time. This buildup lowers indoor air quality and puts your family at risk of breathing in pollutants that can cause allergies or breathing problems.
Choosing professional cleaning with safe methods cuts down these airborne irritants. That leads to better indoor allergen control and improves indoor environmental health for your whole family.
Our certified techs clean well without using harmful chemicals or causing risks. This leaves you with fresher, healthier air that helps everyone feel better all year long.
A Closer Look at Our Process
Our process for air duct sealing and coating is built around precision, safety, and long-term performance. Each step is carefully planned to ensure your home’s duct system operates at peak efficiency with minimal disruption.
Initial Inspection and Airflow Testing
Using airflow meters, infrared tools, and video scopes, we map your duct system and locate all leaks, damage, and weak points.
Sealing the Duct System
Based on the test results, we use a combination of brush-on mastic and reinforced foil tapes to completely seal all problem areas
Interior Duct Coating
For older or exposed ducts, we apply an antimicrobial, elastomeric coating throughout the interior duct surfaces. This process improves airflow.
Final Testing and System Check
Once everything is sealed and coated, we re-test the system for airflow improvement and verify temperature consistency throughout the home.
Energy Efficiency and Cost Savings with Air Duct Sealing
Sealing air ducts stops leaks where warm or cool air escapes before reaching rooms. This energy efficient duct sealing keeps more heated or cooled air inside your home. Some benefits of sealing ducts:

Advanced Methods for Air Duct Sealing and Coating
Inspection and Diagnostics
Our team begins with a thorough inspection of your HVAC system using video cameras and air pressure tests to identify leak points and degraded areas.
Aerosol-Based Sealing
Using safe and effective sealing materials, we distribute an aerosolized sealant inside your duct system. This material naturally finds and seals even the smallest cracks and holes, reducing air loss immediately.
Surface Coating Solutions
For ducts with internal corrosion or moisture problems, we apply a durable coating material designed to withstand heat and inhibit mold growth. These coatings also add a protective layer to extend the life of your duct system.
The Role of Air Duct Coating in Long-Term Durability
Air duct coating is typically applied after sealing and is used to reinforce ductwork and prevent future issues. The coating is a specialized compound that lines the interior of the duct and creates a smooth, resilient surface. This can reduce internal friction, prevent microbial growth, and protect against corrosion.
When Is Duct Coating Recommended?
1. Older duct systems showing signs of surface degradation
2. Metal ducts with minor internal rusting
3. Systems with recurring mold or mildew issues
4. Homes in high-humidity areas

Duct Sealing and Coating Maintenance Tips
After sealing and coating, regular maintenance ensures the longevity and efficiency of the duct system:
Regular Inspections
Schedule periodic checks to detect any new leaks or issues.
Filter Replacement
Change HVAC filters as recommended to maintain air quality.
Monitor Energy Usage
Keep an eye on energy bills for any unexpected increases.
