Commercial Aeroseal DuctSealing for Facilities
Seal duct leaks without demolition. Improve efficiency, airflow, and compliance.
Commercial Buildings Lose Significant Energy Through Leaking Duct Systems
HVAC duct leakage is one of the most common—and costly—sources of energy waste in commercial and industrial facilities. Studies show that HVAC systems can lose up to 30% of conditioned air through duct leaks, reducing system efficiency and driving up operating expenses.
For property owners and facility managers across Los Angeles, duct leakage can also contribute to:
- Challenges meeting Title 24 compliance requirements
- Failed or delayed commissioning and retro-commissioning
- Increased tenant comfort complaints
- Uneven temperatures across zones, floors, or tenant spaces
In many buildings, studies indicate that 25–60% of heated and cooled air is lost before it ever reaches occupied areas. Beyond energy waste, duct leakage can negatively impact indoor air quality (IAQ) by allowing contaminants, dust, and unfiltered air into the system.
Poor IAQ has been linked to increased allergy and asthma symptoms, as well as “sick building syndrome”—conditions that can affect occupant health and productivity. Research, including findings from the NIH, shows that improving indoor air quality can enhance workplace productivity, support better learning environments, and reduce health-related symptoms in commercial and industrial settings.
What is Aeroseal Duct Sealing?
Aeroseal is a patented technology developed at Lawrence Berkeley National Laboratory that seals air leaks inside HVAC duct systems.
Instead of manually sealing ducts from the outside, Aeroseal injects microscopic sealant particles into the duct system. Escaping air draws these particles to the edges of leaks, where they accumulate and seal the opening.
The process allows technicians to seal leaks in hidden ductwork located behind ceilings, walls, and mechanical spaces.
Aeroseal Commercial Sealing Process
1️⃣ Duct Leakage Test
Technicians measure the amount of air leaking from the HVAC duct system.
2️⃣ System Preparation
The duct system is isolated and connected to the Aeroseal equipment.
3️⃣ Aeroseal Application
Sealant particles are injected into the duct system and drawn to leakage points.
4️⃣ Verification Test
Software verifies the reduction in duct leakage after sealing.
This process provides measurable results and documentation of improved duct performance.

Studies show 25–60% of heated and cooled air can be lost through duct leakage before it reaches living spaces. Poor indoor air quality (IAQ), heightened allergy symptoms or sick building syndrome (literally when indoor air issues make people sick). According to the NIH, studies show that improvement of IAQ increases office productivity and school learning, and improves sleep significantly while decreasing the risk of allergic and asthmatic symptoms within residential, commercial, and industrial spaces.

What is Aeroseal Duct Sealing?
Aeroseal duct sealing is a patented breakthrough technology that tackles leaks from the inside out.
Aeroseal duct sealing software allows our technicians to conduct a duct leakage test—accurately measuring the duct leakage in residences. The Aeroseal duct sealing process puts escaping air under pressure and causes polymer particles to first stick to the edges of a leak and then to each other, until the leak is closed.

Aeroseal vs. Traditional Duct Sealing Methods
For large commercial and industrial facilities, Aeroseal offers a more efficient, less disruptive alternative to traditional duct repair or full system replacement.
Unlike manual sealing methods—such as tape, mastic, or external patching—Aeroseal technology seals leaks from the inside of the duct system, reaching areas that are otherwise inaccessible and ensuring long-lasting, airtight results.
Compared to duct replacement, Aeroseal:
- Requires significantly less downtime and disruption to operations
- Eliminates the need for demolition or major reconstruction
- Provides measurable leakage reduction and system performance improvement
In most commercial applications, the investment in Aeroseal is offset through energy savings within 3 to 7 years, while also improving airflow performance and overall system efficiency.
According to the U.S. Department of Energy, duct sealing is one of the most cost-effective energy efficiency upgrades for commercial buildings. In some cases, Aeroseal projects may also qualify for tax incentives or energy efficiency programs.
Aeroseal Benefits for Commercial & Industrial Facilities
Aeroseal duct sealing delivers measurable performance improvements for large commercial and industrial buildings—without costly demolition or operational disruption:
- Significantly reduce HVAC energy consumption and operating costs
- Improve airflow balance across large facilities
- Enhance occupant comfort in commercial environments
- Reduce odors, fumes, and air leakage between zones
- Improve overall HVAC system performance and efficiency
Industry Insight
