Our Duct Cleaning Process

Step 1: Pre-Inspection

Visual and camera inspection of ductwork to identify mold, damage, or disconnected ducts — plus upfront recommendations and pricing.

Step 2: System Preparation

Drop cloths and floor protection laid down, furniture covered, registers sealed, and negative pressure equipment set up before any cleaning begins.

Step 3: Source Removal Cleaning

Rotating brushes and compressed air agitate debris throughout the duct interior, while HEPA-filtered negative air machines extract contaminants from the entire system. Each supply register, return grille, and vent cover is removed, cleaned, and reinstalled.

Step 4: Furnace & Air Handler Cleaning

Blower wheel, furnace cabinet, evaporator coil, and condensate drain pan are all cleaned to restore full system efficiency.

Step 5: Sanitization

EPA-registered antimicrobial and deodorizing treatments available, safe for occupants and pets. Mold inhibitor applied where needed.

Step 6: Final Inspection

Camera documentation confirms clean ducts, airflow is tested, all covers are secured, and we walk you through before-and-after findings with maintenance recommendations.

Common Duct Problems We Repair:

Air Leaks in Ductwork: Leaky ducts waste 20-40% of heated and cooled air:

• Disconnected duct sections
• Separated seams and joints
• Holes or tears in duct material
• Loose or missing connections
• Deteriorated duct tape or mastic
• Poor original installation

Signs of Duct Leaks:

• High energy bills despite normal usage
• Uneven temperatures in different rooms
• Difficulty maintaining comfortable temperature
• Excessive dust in some rooms
• Whistling sounds from ductwork
• Rooms that never get comfortable

Damaged Ductwork:

• Crushed or collapsed flexible ducts
• Torn or punctured duct sections
• Corroded metal ducts (especially in crawlspaces)
• Deteriorating duct insulation
• Animal damage from rodents or pests
• Construction damage during renovations

Undersized or Poorly Designed Ducts:

• Insufficient airflow to certain rooms
• Noisy airflow in ductwork
• Rooms too hot or too cold
• Pressure imbalances in system
• Restricted airflow causing efficiency loss

Disconnected Ductwork:

• Ducts separated from registers or boots
• Sections fallen apart in attic or crawlspace
• Connections pulled loose from air handler
• Return ducts disconnected
• Complete loss of airflow to rooms

Inadequate Insulation:

• Ductwork in unconditioned spaces (attics, crawlspaces)
• Missing or deteriorated duct insulation
• Energy loss from uninsulated ducts
• Condensation problems on cold ducts
• Excessive heat gain/loss

Our Ductwork Repair Process

Comprehensive Inspection

Visual inspection, airflow and pressure testing, and thermal imaging across attics, crawlspaces, and basements to identify all issues before any work begins.

Professional Duct Sealing

We use mastic sealant, UL-181 foil-backed tape, and mechanical fasteners for accessible leaks — plus Aeroseal technology to seal inaccessible leaks from the inside.

Duct Replacement & Modification

Damaged sections replaced, undersized ducts upgraded, poorly routed runs rerouted, and all new ductwork installed to code with proper supports.

Duct Insulation

Uninsulated or deteriorated duct insulation replaced with the correct R-value for Littleton’s climate, including vapor barriers and sealed insulation seams.

Post-Repair Cleaning

Debris from the repair process cleared, newly exposed sections cleaned, and the full system restored for improved indoor air quality.

Performance Testing

Airflow, temperature balance, and pressure testing confirm all leaks are sealed and the system is operating at peak efficiency.

Benefits of Duct Cleaning & Repair in Littleton

Better Air Quality: Removes dust, pollen, pet dander, mold spores, and allergens, especially impactful for allergy and asthma sufferers.

Energy Savings: Sealed ducts eliminate 20–40% air loss, reducing heating and cooling bills through improved system efficiency.

Even Comfort: Consistent airflow and temperatures throughout every room, with fewer hot and cold spots.

Longer HVAC Life: Less strain, fewer cycles, and cleaner components mean reduced maintenance and a longer-lasting system.

Cleaner Home & Fresh Air: Less dust on surfaces, eliminated musty or pet odors, and fresher air circulating throughout.

Types of Ductwork We Service in Littleton

Sheet Metal

Rigid galvanized steel, the most durable type, common in older Littleton homes, and capable of lasting 50+ years with proper care.

Flexible Ducts

Standard in modern homes but prone to crushing and kinking. We repair, replace, and optimize flex duct for proper airflow.

Fiberglass Duct Board

Rigid panels with built-in insulation that can deteriorate over time. We seal, repair, and replace as needed.

Fiberboard Ducts

Less common in newer builds and susceptible to mold if moisture is present. We inspect, clean, and seal thoroughly.

Return Air Plenums

Building cavities used as return air paths are inefficient and problematic — we install proper return ductwork to improve both efficiency and air quality.

Most homes every 3–5 years. Every 2–3 years with pets, every 1–2 years with multiple pets or smokers. Also recommended after renovations, flooding, or moving into a previously occupied home.

Other factors that increase frequency: number of occupants, home age, allergy or respiratory concerns, and nearby construction or dusty environments.
