Aeroseal
Aeroseal duct sealing technology offers a highly effective solution for enhancing the efficiency of your HVAC system. It utilizes a patented, non-toxic aerosol sealant designed to seal ductwork efficiently. The process works by pressurizing the duct systems, pushing sealant particles directly to the leaks, and sealing them from the inside out without having to coat the entire interior of the ducts.
This technology is not only efficient but also exceptionally reliable. It delivers sealant precisely where needed, ensuring the integrity of the ductwork. The sealing process is monitored in real-time, allowing for a comprehensive coverage and effectiveness assessment. This meticulous approach ensures you experience improved HVAC efficiency, air quality, and overall comfort within your space.
By choosing Aeroseal, you are taking a proactive step toward enhancing your home’s comfort and efficiency.
Why Aeroseal Works So Well
Targets leaks that are inaccessible
Traditional manual sealing can only reach visible seams and accessible joints. Aeroseal reaches leaks hidden in cavities, behind insulation, and inside wall chases.
Minimal disruption
No demolition, no attic tear-outs, and usually no major mechanical disassembly — most residential jobs finish in a few hours.
Measurable outcomes
We perform diagnostic duct leakage testing and issue a detailed report showing pre-seal leakage (CFM25 or CFM50) and post-seal reduction so you can clearly measure ROI.
Improves comfort & air quality
By sealing pathways that draw dust, insulation fibers, or attic air into the system, Aeroseal helps lower allergen and dust circulation while improving room-to-room comfort.
Energy & equipment benefits
Sealed ducts deliver conditioned air to living spaces more efficiently, reducing runtime and system wear.
Who Sees the Biggest Improvements
Aeroseal is especially valuable if you have any of the following:
- Rooms that are consistently hotter or colder than the rest of the house.
- High energy bills despite a relatively new HVAC system.
- Ductwork in unconditioned spaces (attics, crawlspaces, garages).
- Old flexible ducts with many joints or long runs.
- Renovations or additions where duct joints increased.
- Allergy concerns or odors that seem to come from the ventilation system.
If you own a seasonal rental or a home that’s winterized part of the year, we’ll explain commissioning steps so you get the benefit when the property is occupied
What We Can Also Do for You
We treat Aeroseal as one powerful tool in a broader comfort and efficiency strategy. Our technicians can deliver these complementary services, all coordinated for minimal disruption:
Full Duct Cleaning & Sanitation
When ducts are heavily contaminated, a pre-seal cleaning improves seal quality and indoor air. We offer safe, tested cleaning methods and sanitizing options when appropriate.
Duct Insulation Upgrades
Sealing combined with proper insulation in attics or crawlspaces prevents heat loss/gain and magnifies Aeroseal’s efficiency benefits.
Airflow Balancing & Register Optimization
After sealing, rebalancing ensures rooms receive the right airflow; we tune dampers, adjust register locations, and recommend zone strategies.
Return & Transfer Location Improvements
We identify poor return locations or pressure imbalances that can undermine comfort and propose corrective wiring or duct modifications.
HVAC Tune-Up & Maintenance Plans
Seal gains are best preserved with healthy HVAC equipment — we offer seasonal tune-ups and maintenance agreements.
Frequently Asked Questions
Is Aeroseal safe for my family and pets?
Yes. The Aeroseal sealant is non-toxic once it cures and the process is performed with ventilation and manufacturer procedures. Our crew follows safety steps and clears the space afterwards. If you have specific chemical sensitivities, tell us in advance so we can further tailor our approach.
How long does the seal last?
Aeroseal creates a durable, flexible seal that is designed to last for many years. Normal system use won’t break the seal; major duct disassembly or physical damage could require touch-ups. We explain how to avoid actions that might disturb the sealed areas.
Will Aeroseal fix all my comfort problems?
Aeroseal fixes leakage in the duct system, which is a major cause of uneven comfort. However, some comfort issues are also caused by undersized equipment, poor insulation, or duct layout problems. We diagnose and clearly communicate whether Aeroseal alone is the right fix or part of a larger solution.
Do you need to clean ducts before sealing?
If ducts are clogged with debris or have loose material, we may recommend cleaning first. Very dirty systems can reduce the quality of the seal. We inspect and recommend cleaning when it will improve outcomes.
Does Aeroseal affect airflow or static pressure?
Properly executed Aeroseal reduces leakage without significantly increasing static pressure. Our technicians monitor static pressure and airflow, and we adjust or recommend upgrades if the system needs moderation for optimal performance.
How much leakage reduction should I expect?
Outcomes vary by system; many homes see leakage reductions in the range of 50–90% depending on starting conditions. We provide an estimated target range in the written quote based on initial diagnostics.
Will Aeroseal void my HVAC warranty?
No. Aeroseal is a non-invasive process and is an accepted professional service; it does not void equipment warranties. We document everything and work to manufacturer guidelines.
How disruptive is the work?
Residential jobs are usually completed in a few hours with minimal footprint. We protect floors and furniture, close off work areas, and clean up thoroughly.
