Aeroseal Services

Improved Indoor Air Quality

Aeroseal prevents dust, pollen, humidity, and airborne pollutants from entering your ducts through cracks or gaps. By sealing leaks, it helps reduce allergy and asthma triggers, prevents mold and mildew growth, and ensures your air is cleaner and safer to breathe—especially important in Florida’s high-humidity climate.

Enhanced HVAC Performance

Leaky ducts force your HVAC system to work harder to maintain your desired temperature. Aeroseal stops conditioned air from escaping into attics, crawlspaces, or unconditioned areas, which allows your system to deliver air more efficiently—improving airflow, comfort, and overall system performance.

Lower Energy Bills

Aeroseal can reduce your heating and cooling costs by up to 40%, saving homeowners as much as $850 per year. Sealing leaks is a cost-effective alternative to duct replacement—and the energy savings start immediately.

Extended HVAC Lifespan

By minimizing strain on your HVAC system, Aeroseal reduces wear and tear on motors, blowers, and compressors. This helps prevent breakdowns, cuts down on repair costs, and extends the life of your equipment—delaying the need for a costly replacement.

Eliminates Hot & Cold Spots

When air leaks before it reaches certain vents, rooms further down the duct line stay warm while others become overcooled. Aeroseal balances your airflow—leveling out temperatures across your entire home and eliminating uncomfortable hot and cold spots.

Aeroseal duct sealing is quick, clean, and results-driven. At Millian Aire, we follow a proven four-step process to ensure every leak is identified, sealed, and documented—giving you immediate results and long-term comfort.

Step 1: Free Estimate

Call us or schedule online at your convenience. One of our technicians will provide a completely free, no-obligation estimate, so you can explore your options without pressure.

Step 2: Pre-Seal Test

We conduct an initial pressurization test on your duct system to create a "before" snapshot of its condition. This test identifies how much air is leaking and helps guide the sealing process.

Step 3: Aeroseal Application

A safe, non-toxic sealant is blown into your ducts under pressure. Using computer-controlled equipment, we precisely monitor the flow and ensure every crack and gap is sealed from the inside—without cutting into walls or ceilings.

Step 4: Post-Seal Test & Results

Once the process is complete, we conduct a second test to measure the improvement. You’ll see a detailed report showing exactly how much your duct efficiency has improved—often up to 90% less leakage.

Aeroseal technology is only as effective as the technician applying it. At Millian Aire AC & Heating, we bring decades of HVAC experience and a meticulous approach to every Aeroseal project—ensuring your ducts are sealed properly the first time.

Precision Matters with Aeroseal

A successful Aeroseal application requires:

• Accurate pre-seal testing to pinpoint leakage
• Real-time monitoring and adjustments during the sealing process
• Final post-seal verification to confirm airtight results

Without these steps done correctly, you could be left with persistent leaks and the added cost of follow-up repairs.
