Our Professional Duct Cleaning Process

Real duct cleaning requires specialized equipment and proper technique to actually remove contaminants rather than just redistributing them. We follow industry best practices to ensure thorough, effective cleaning that delivers measurable results.

Our technicians begin by creating strategic access points in your ductwork at locations that allow complete cleaning while minimizing penetrations. Each access point gets professionally sealed after we finish, often leaving your system more airtight than before we arrived.

We establish negative pressure by connecting powerful HEPA-filtered vacuum equipment to your main trunk line. This creates a contained environment where everything we dislodge flows toward collection instead of escaping into your home. The vacuum runs continuously throughout the entire process, maintaining protective negative pressure.

Different tools work through your ductwork to physically scrub interior surfaces clean. Rotating brushes spin against duct walls, breaking loose stuck-on debris and growth. Compressed air agitation blasts stubborn contamination free. The specific techniques vary based on whether you have flexible duct, rigid metal, or duct board.

What Gets Cleaned

• All main trunk lines carrying bulk airflow
• Individual branch runs serving each room
• Return air pathways and plenums
• Supply and return registers throughout your home
• Boot connections where ducts meet ceiling vents
• Air handler compartment and accessible coil surfaces

When mold growth is present, we apply EPA-registered antimicrobial treatments specifically designed for HVAC systems. These treatments prevent regrowth without introducing harmful chemicals into your breathing air.

Why Duct Sealing Is Critical

While cleaning addresses what’s inside your ducts, sealing fixes how well they actually deliver conditioned air to your rooms. The energy waste from leaky ductwork often surprises homeowners once they understand the scope of the problem.

Many Florida homes have ductwork installed with minimal attention to air sealing. Connections between sections typically relied on fabric duct tape alone, which fails rapidly in extreme attic heat. After just five to ten years, much of this tape has deteriorated completely, leaving gaps at virtually every connection point.

The financial impact adds up quickly. If your home spends $200 monthly on summer cooling and has typical 30% duct leakage, you’re wasting $60 every single month. That’s $300 per summer season and $3,000 over ten years pumped uselessly into your attic from a problem most homeowners don’t even know exists.

Our Sealing Process

Mastic Sealant Application We use professional-grade mastic, a paste-like material that dries flexible and withstands extreme temperatures for decades. Every accessible joint, connection, and gap gets thoroughly sealed.

Mechanical Reconnections Disconnected sections receive proper mechanical reconnection with sheet metal screws or fasteners before sealing. Simply covering a separation doesn’t create lasting repairs.

Fiberglass Mesh Reinforcement Larger openings get reinforced with fiberglass mesh before mastic application, creating structural integrity that prevents future separation.

Insulation Repair Damaged duct insulation gets replaced or repaired, preventing temperature loss as conditioned air travels through hot attics.

Return air leaks deserve special attention because they’re actually worse than supply leaks. When return ducts leak in your attic, they pull 140-degree attic air into your system instead of relatively cooler indoor air. This superheated air carries dust, insulation particles, and potentially mold spores while forcing your AC to work much harder.

Combined Cleaning and Sealing Benefits

Addressing both issues simultaneously provides benefits that exceed either service alone. Clean ducts with sealed connections deliver maximum airflow efficiency. Your system moves air easily through clean interior surfaces while sealed connections ensure that air actually reaches intended destinations instead of leaking into attics.

Indoor air quality improves dramatically when you remove existing contaminants through cleaning while preventing new contamination infiltration through sealing. Homes with sealed return ducts no longer pull attic dust and allergens into living spaces, keeping newly cleaned ducts cleaner much longer.

The energy savings compound in interesting ways. Clean ducts reduce resistance on your blower motor, letting it move air more efficiently using less electricity. Sealed ducts ensure this efficiently moved air reaches rooms instead of attics. The combination typically reduces cooling costs 20-35% compared to dirty, leaky ductwork.

Health Improvements

• Reduced allergen circulation from removed dust and mold
• Eliminated musty odors from biological growth
• Lower dust mite populations in cleaner environment
• Decreased respiratory irritation for sensitive family members
• Prevention of new contamination through sealed returns

Energy and Comfort Benefits

• 20-35% reduction in cooling costs
• More consistent temperatures between rooms
• Improved system performance and lifespan
• Quieter operation from better airflow
• Faster cooling when system activates

What to Expect During Service

Understanding the service process helps you prepare properly and know what to expect on the day we arrive. Most combined cleaning and sealing services complete in one day, though larger homes with complex duct systems may require additional time.

We’ll need clear access to your attic or crawlspace where most ductwork runs. If you use your attic for storage, creating temporary pathways or relocating some items helps us work efficiently. We navigate these spaces carefully, but extensive storage can limit access to certain duct sections.

The actual work varies in length depending on your home size and duct complexity. A typical single-story home with straightforward duct layout requires 4-6 hours for combined cleaning and sealing. Larger two-story homes or those with complex configurations might need 8-10 hours, though we complete even extensive work in a single day whenever possible.

You’ll notice minimal disruption inside your home. Most work occurs in attics or crawlspaces. We access your living space primarily to remove and clean registers and to reach your air handler. We use drop cloths to protect flooring and vacuum any dust from register removal.

After completing the work, we conduct a final walkthrough showing documentation of what we found, what we addressed, and the results achieved. You’ll see before and after photos, understand exactly what was cleaned and sealed, and receive recommendations for maintaining your improved system.

Maintaining Your Investment

Professional duct cleaning and sealing provides lasting benefits, but proper maintenance extends these benefits and protects your investment. The most important task is also the simplest: changing your air filter consistently.

During Florida’s peak cooling season from May through September, filters should be changed monthly. This frequent replacement prevents dust that bypasses filters from accumulating in your freshly cleaned ductwork. Moving into fall and winter when your system runs less, you can extend to every 60 days, though monthly replacement remains ideal for homes with pets or severe allergies.

Annual professional HVAC maintenance helps verify that your sealed ductwork remains intact. Technicians performing tune-ups can spot new leaks developing before they become significant problems and identify any sections needing touch-up sealing.

Controlling humidity throughout your home prevents the condensation that promotes mold growth in ductwork. If your home feels clammy despite running AC, consider whole-home dehumidification. Maintaining indoor humidity between 45-55% keeps ducts dry and prevents mold growth that would necessitate repeated cleaning.

Cost and Value Analysis

Service Investment

Duct Cleaning (1,500-2,500 sq ft home): $450-700 Includes all accessible supply and return ducts, register cleaning, HEPA vacuuming, and antimicrobial treatment if needed.

Duct Sealing: $600-1,200 Mastic sealing all accessible connections, mechanical repairs of disconnections, insulation repair, and performance verification.

Combined Service Package: $900-1,500 Better value than separate services with single-visit convenience addressing both air quality and efficiency.

Return on Investment

The financial return comes primarily through energy savings. A home spending $200 monthly on summer cooling with typical 30% duct losses wastes $60 monthly. Professional sealing reducing losses to 8-10% saves approximately $40-50 monthly during peak season.

Over a typical cooling season, that’s $200-250 in savings. Year-round, considering Florida’s extended cooling needs, savings often reach $300-450 annually. Your investment in combined services typically pays for itself within 2-4 years purely through energy savings, then continues providing returns throughout your ductwork’s lifespan.

Additional value comes from avoided damage costs, improved equipment longevity from cleaner operation, and health benefits that are harder to quantify financially but very real for families with allergies or respiratory sensitivities.
