Traditional Duct Sealing vs Aeroseal
Introduction
Leaky ductwork is one of the most common hidden problems in Florida homes. According to the U.S. Department of Energy, the average home loses 20–30% of conditioned air through duct leaks. That’s money wasted on energy bills, added strain on your HVAC system, and hot or cold spots throughout your home.
Two main solutions exist: traditional duct sealing and Aeroseal technology. Here’s how they compare—and which might be best for your Tampa Bay home.
What Is Traditional Duct Sealing?
How It Works
- A technician locates leaks manually by inspecting ductwork.
- Mastic sealant or foil-backed tape is applied to holes, seams, and cracks.
- In some cases, ducts are wrapped with insulation for added efficiency.
Pros
- Effective at sealing large, visible leaks.
- Lower upfront cost than Aeroseal.
- Straightforward process many HVAC technicians can perform.
Cons
- Labor-intensive and time-consuming.
- Hard to access ducts in walls, ceilings, or tight attic spaces.
- Typically seals only 60–70% of total leaks, leaving hidden ones untreated.
What Is Aeroseal Duct Sealing?
How It Works
- The duct system is temporarily sealed and pressurized.
- A computer-controlled machine introduces a safe, non-toxic sealant mist into the ducts.
- The particles find leaks and bond to them from the inside out—even gaps as small as a pinhole.
- The system generates a before-and-after leakage report showing exactly how much efficiency was gained.
Pros
- Seals hidden leaks that traditional methods miss.
- Proven to reduce leakage by up to 95%.
- Improves comfort by eliminating hot and cold spots.
- Helps lower energy bills and extend HVAC lifespan.
Cons
- Higher upfront cost than traditional sealing.
- Requires certified Aeroseal equipment and technicians.
Tampa Tip: Why Aeroseal Matters in Florida Homes
In Tampa Bay, most ductwork runs through hot attics or tight crawlspaces—places where manual sealing is nearly impossible. Even small leaks in these areas can waste a lot of energy as cooled air escapes into 120°F attic air.
Because Aeroseal works from the inside out, it seals every leak throughout the entire system, making it especially effective in Florida’s climate.
Which Option Is Better?
- Traditional Duct Sealing: Best for homes with a few accessible leaks and a smaller budget.
- Aeroseal: Best for homeowners who want maximum energy savings, verified results, and a long-term solution.
Many Tampa homeowners find that Aeroseal pays for itself in just a few years through lower utility bills and improved comfort.
