Aeroseal FAQ: Homeowner Questions Answered About Duct and AeroBarrier® Sealing
If you're a homeowner curious about how Aeroseal and AeroBarrier® can improve your home's comfort, energy efficiency, and indoor air quality, you're in the right place. This FAQ covers the most common questions homeowners have about our proven duct and envelope sealing solutions. From understanding how they work to the benefits they offer, we’ve got you covered.
Understanding the Problem: Hidden Leaks in Your Home
When you walk through your home, you probably don’t think about the tiny gaps behind your walls, under your floors, or around your ductwork. But those unseen leaks are doing more than letting a little air in or out — they’re quietly driving up your energy bills, compromising your comfort, and letting in allergens and outdoor pollutants.
That’s where Aeroseal and AeroBarrier® come in. These proven air-sealing technologies were developed to fix what most people don’t even realize is a problem: invisible air leakage. Whether you’re building a new home or living in one that’s been around for decades, understanding these solutions can make a measurable difference in how your home feels and performs.
1. What Do Aeroseal and AeroBarrier Do?
Aeroseal and AeroBarrier are air-sealing technologies that close gaps and leaks from the inside out. Aeroseal targets your home’s ductwork, sealing leaks in heating and cooling systems that often account for major energy loss. AeroBarrier seals the building envelope — the outer shell of your home — making sure that the conditioned air you pay for stays inside and unwanted air stays out. Both systems use a computer-guided process to precisely locate and seal leaks. There’s no need to tear out drywall or hunt for leaks by hand. It’s a verified process, and you get the before-and-after data to prove it.
2. Will I Notice a Difference?
Most homeowners do — almost immediately. The most common feedback is simple but powerful: “This home just feels better.” That’s because a sealed home tends to stay warmer in winter and cooler in summer, without cold spots, uneven temperatures, or that constant hum of your HVAC trying to keep up.
You may also notice:
- Less dust on surfaces
- Reduced drafts around windows and doors
- Improved air quality
- Quieter rooms, especially in shared-wall buildings
3. How Long Does the Seal Last?
Aeroseal and AeroBarrier use flexible water-based sealants that stay intact, even as your home naturally shifts over time. Accelerated aging tests show they last over 50 years, thanks to their 30% flex rating, which means they bend and move with the structure without breaking the seal. Once applied, they’re in place for the long haul.
4. Is It Safe for My Family?
Yes. Safety is a core part of the design. Both Sealants are verified low VOC, meaning they meet strict third-party standards for low chemical emissions.
- No off-gassing
- No strong odors
- No harmful chemicals
Because it’s water-based and non-toxic, it’s safe for children, pets, and anyone living in the home.
5. What If My Home Is Older? Will This Still Work?
Definitely, in fact, older homes tend to benefit the most from Aeroseal as ductwork in existing homes often leaks more than homeowners realize, and traditional repairs would require opening walls or ceilings. Aeroseal works from the inside of the ducts, which means no demolition or mess.
6. Does It Work in All Climates?
Yes. Aeroseal and AeroBarrier are designed to perform reliably in every climate zone — from humid southern summers to dry desert heat and harsh northern winters. Sealing your home improves your comfort and reduces the strain on your HVAC system regardless of where you live.
7. What Kind of Savings Can I Expect?
Homes built to meet the 2021 IECC energy code, with envelope sealing, can save up to $700 annually on energy bills. Even more importantly, sealed homes reduce the demand on heating and cooling systems, which can extend the life of your HVAC equipment and help you avoid costly repairs.
8. Do These Technologies Support Green Certifications?
Yes. Many builders and homeowners use Aeroseal and AeroBarrier to help meet high-performance standards like:
- ENERGY STAR®
- IECC 2021 Code
- Passive House
- Net Zero Ready
- Other green building and energy efficiency certifications
These certifications add long-term value to your home and may make you eligible for rebates and incentives, depending on your local utility provider.
