Frequently Asked Questions
Aeroseal is a modern method of sealing air leaks in your duct system from the inside, without needing to tear into walls, ceilings, or ductwork.
Instead of manually sealing ducts, the process uses a specialized machine to push a fine mist of sealant through your system. The sealant particles travel through the ducts and stick to the edges of leaks, sealing them over time.
Here’s how the process works:
This method can seal leaks that are difficult or impossible to reach with traditional duct sealing.
In homes across Fredericksburg, Kerrville, and the Texas Hill Country, duct leaks can lead to uneven temperatures, higher energy bills, and reduced comfort. Aeroseal offers a way to improve system performance without major disruption to your home.
It’s often used as part of a larger effort to improve airflow, efficiency, and indoor air quality.
Aeroseal duct sealing can be a strong investment, but it depends on your home and HVAC system condition.
In many homes, especially older ones, ductwork can leak 20–30% of conditioned air before it ever reaches your living space. Sealing those leaks can make a noticeable difference in comfort and efficiency.
Here’s when Aeroseal is typically worth it:
Key benefits of Aeroseal include:
However, it may not be the best option if:
In the Texas Hill Country, where HVAC systems run hard during long, hot seasons, sealing duct leaks can help reduce strain on your system and improve comfort throughout your home.
The best way to know if Aeroseal is worth it is through a professional duct leakage test. This shows how much air you’re losing and whether sealing will deliver a meaningful return on investment.
Aeroseal duct sealing is priced based on your home’s size, the condition of your ductwork, and how complex your system is.
Most homeowners can expect to pay anywhere from $1,500 to $4,000 for a typical home, though larger or more complex systems can reach $6,000 or more.
Several factors influence the total cost:
Aeroseal is often more efficient than traditional duct sealing because it seals leaks from the inside, including areas that are hard to reach manually. The process typically includes pre-testing, sealing, and post-testing to verify results.
For homeowners in Fredericksburg, Kerrville, and surrounding areas, sealing ducts can improve airflow, increase energy efficiency, and reduce strain on your HVAC system.
The most accurate way to get pricing is through a professional evaluation, since every home’s duct system is different.
Aeroseal duct sealing is a relatively quick and non-invasive process compared to traditional duct repairs.
In most homes, the full process takes around 4 to 6 hours, though some smaller systems may be completed faster and larger or more complex homes may take longer. The exact timing depends on:
The process itself includes:
Most homeowners can expect the entire service to be completed in a single day, with minimal disruption and no need for major demolition.
For homes in Fredericksburg, Kerrville, and across the Texas Hill Country, Aeroseal offers a fast way to improve airflow, comfort, and energy efficiency without extensive construction.
Aeroseal Duct Sealing Near Me
If your home never quite feels right—one room always warmer, another always colder—your HVAC system might not be the problem. The real issue could be hidden leaks in your ductwork, quietly wasting energy behind the walls.
At 72 Degrees Texas, we use Aeroseal duct sealing to fix this problem from the inside out. It’s a modern solution for homeowners who want their systems to work efficiently without tearing into their homes. And with decades of experience working on homes across the Texas Hill Country, we know how to get results you can feel.
Traditional duct sealing requires crawling through attics or cutting into walls to tape and seal gaps manually. Aeroseal skips all that.
We use a computer-controlled process to push a safe, mist-like sealant through your ducts. This mist naturally finds and seals leaks—no matter how small—without coating the entire duct system. The process takes just a few hours, but the results can be dramatic.
If you’ve tried everything else—upgraded your HVAC, installed smart thermostats, even added insulation—and still notice uneven airflow or rising energy bills, Aeroseal is a smart next step.
Ductwork in our area often runs through attics, basements, or wall cavities where heat, dust, and age take a toll. Homes built decades ago may never have had proper duct sealing. Newer homes may have flexible ductwork that’s prone to shifting and leaking over time.
Aeroseal works especially well in these conditions. Whether your system is decades old or recently installed, sealing leaks from within keeps air moving exactly where it’s supposed to go—without pulling in attic dust or losing cooled air to crawlspaces.
When you schedule an Aeroseal service with 72 Degrees Texas, here’s what happens:
You don’t need to move furniture, open walls, or schedule days off. Most jobs are done the same day.
Yes—especially if your home has older ductwork or signs of leakage. Leaky ducts force your HVAC system to work harder and longer, which adds up on your monthly bill. Sealing those leaks can cut energy waste by up to 30%.
Wondering about the Aeroseal duct sealing cost? It varies depending on the size and condition of your duct system, but many homeowners recover the cost in energy savings over time. We provide honest quotes, explain your options, and never pressure you into extras you don’t need.
If you’re not sure whether your home needs Aeroseal, we can help. Start with an air duct inspection to see how your system is performing. If we find gaps, weak airflow, or signs of energy loss, Aeroseal might be the fix. We can also pair your sealing service with HVAC maintenance, duct cleaning, or attic insulation to give your home a full performance upgrade.
We’ve been helping families across the Hill Country since 1986, and we’re proud to offer services that actually solve problems. Aeroseal is one of the most effective ways to improve HVAC efficiency and comfort without major disruption. It’s clean, fast, and built to last.
If your system is working overtime but your home still feels off, let’s take a look at your ductwork. Aeroseal could be the simple fix that makes your whole system work better.
