What is Duct Sealing?
Duct sealing is a proven method for closing gaps and leaks in ductwork for residential buildings. The process involves using specialized, non-toxic aerosol sealants that are distributed through the duct system under pressure. These sealant particles are carried directly to gaps or holes, where they cling and build up until the leak is sealed—without coating the entire inside of the duct.
This targeted approach ensures that only the necessary spots are addressed, preserving the overall integrity of your ductwork. The entire process is monitored in real time to verify coverage and effectiveness, delivering measurable improvements in HVAC efficiency, indoor air quality, and year-round comfort.
Whether your property is newly built or decades old, duct sealing offers a precise solution to boost airflow, reduce energy waste, and restore peace of mind. With reliable, local expertise and a knack for adapting to any challenge, we’re committed to keeping Nevada homes comfortable and efficient no matter how tough the desert climate gets.
How Duct Sealing Works
Desert homes in Nevada face unique challenges, from dry air to intense heat—all of which make airtight ductwork essential for lasting comfort and energy efficiency. Here’s how the Aeroseal process restores efficiency, comfort, and peace of mind with unparalleled precision.
Step 1: System Prep and Pressurization
First, every vent and register in your duct system is temporarily sealed. The system is then pressurized to pinpoint exactly where leaks are hiding—even those invisible to the eye. This thorough prep ensures that only leaky areas are targeted for sealing, avoiding unnecessary disruption to your space.
Step 2: Injection of Sealing Particles
With the system prepared, the Aeroseal process introduces safe, water-based sealing particles directly into the pressurized ductwork. These microscopic particles travel on the moving air, automatically seeking out and collecting at each leak point—sealing holes and cracks from the inside out.
Step 3: Real-Time Leak Measurement
Throughout the process, advanced monitoring tools measure the exact amount of air escaping from your ducts. You receive real-time feedback—before, during, and after sealing—so there’s no guesswork about how much airflow (and money) you’re saving.
Step 4: Verified Results and Restored Comfort
At completion, the system delivers a printed report showing a dramatic reduction in duct leakage—often up to a 90% improvement. The result is powerful: optimal airflow, cleaner indoor air, and greater efficiency, so your home stays cooler in Nevada’s desert climates while running more economically year-round.

Frequently Asked Questions
Aeroseal duct sealing is one of the most effective ways to improve airflow, reduce energy waste, and restore comfort—especially in Nevada homes where extreme heat makes HVAC performance non-negotiable. Because the process seals leaks from the inside out and provides measurable before-and-after results, homeowners can feel confident they’re investing in a solution that delivers real impact—not guesswork.
At the same time, it’s normal to have a few practical questions before you commit. Many homeowners want to know how long duct sealing will hold up, whether it’s something they can tackle themselves, and how it compares to replacing ductwork entirely. Here are a few quick answers to help you decide what’s right for your home
Aeroseal duct sealing is designed to be a long-lasting solution, not a temporary patch. Once the sealant particles bond to leak points inside your ductwork, they form a durable seal that can hold up for many years under normal HVAC use.
That said, how long results last depends on factors like the condition of your duct system, whether ductwork is exposed to extreme heat or shifting, and if future renovations or repairs disturb the ducts. For peace of mind, it’s smart to schedule periodic HVAC inspections to confirm your system stays airtight and efficient over time.
In most cases, duct sealing is not a DIY project—especially when you want verified, measurable results. The Aeroseal process requires specialized equipment, careful system pressurization, and real-time monitoring to locate leaks and seal them from the inside without impacting the rest of the ductwork.
DIY methods like tape, mastic, or patching can help with small, visible leaks, but they often miss the hidden gaps that cause the biggest energy loss. Professional duct sealing ensures the job is done thoroughly, safely, and with performance results you can actually measure.
Sometimes—depending on what’s going on with your duct system. Duct sealing is often the best first step when ductwork is generally in good shape but leaking at joints, seams, or small gaps. It can dramatically improve airflow and efficiency without the cost and disruption of full replacement.
However, duct replacement may be worth it if your ductwork is:
- Crushed, disconnected, or poorly designed
- Heavily deteriorated or contaminated
- Undersized or unable to deliver consistent airflow
- Located in areas that make repairs impractical
A professional assessment can help you compare options and choose the most cost-effective fix—whether that’s sealing, targeted repairs, or a full duct upgrade.
