Expert Air Duct Repair and Sealing in Denver, CO
For homeowners across Denver, Aurora, Littleton, Lakewood, and the entire Front Range, a hidden problem within your walls could be draining your wallet and compromising your comfort. At FirstCall Home Services, we specialize in professional air duct repair and sealing services in Denver, CO, designed to restore your HVAC system’s efficiency, improve your indoor air quality, and reduce your energy bills. The dry climate and temperature extremes of Colorado can exacerbate leaks, tears, and disconnections in your ductwork, leading to significant energy loss—often 20-30% of the air moving through your system. Our certified technicians use advanced diagnostic tools and sealing techniques to locate and permanently fix these issues, ensuring your Denver home receives balanced, clean, and efficient airflow. Don’t let conditioned air escape into your attic or crawl spaces. Contact FirstCall Home Services today for a comprehensive ductwork assessment and reclaim your home’s comfort and efficiency.
Why Air Duct Repair & Sealing is Critical for Denver, Colorado Homes
The ductwork in your Denver, Arvada, or Centennial home is the critical circulatory system for your heating and cooling. When this system is compromised due to aging, poor installation, rodent damage, or settling common in Colorado soils, the consequences are immediate and costly:
Skyrocketing Energy Bills: Leaky ducts force your furnace in Boulder or AC in Parker to work 20-40% harder to maintain the desired temperature, leading to shockingly high monthly bills from Xcel Energy or other providers.
Uneven Heating & Cooling: You’ll experience persistent hot and cold spots—maybe your upstairs in Westminster is always stuffy while your basement remains chilly. This is a classic sign of poor airflow distribution due to leaks or blockages.
Poor Indoor Air Quality (IAQ): Leaks in return ducts can pull unfiltered air from attics, crawl spaces, or wall cavities in Historic Denver neighborhoods like Capitol Hill or Baker. This air contains dust, insulation fibers, mold spores, and pests dander directly into your living spaces.
Increased HVAC Wear and Tear: The constant strain of compensating for lost airflow leads to more frequent breakdowns and a significantly shortened lifespan for your expensive HVAC equipment.
Reduced System Capacity: Your properly sized system becomes undersized, struggling to reach set temperatures on the hottest Denver summer days or coldest Front Range winter nights.
Our air duct repair services in Denver, CO, directly combat these issues by restoring your system’s integrity. We seal leaks, remove obstructions, and reinforce damaged sections, ensuring proper ventilation and balanced pressure throughout your home.
Comprehensive Air Duct Services for the Denver Metro Area
1. Professional Air Duct Inspection & Diagnostics
Every lasting repair begins with an accurate diagnosis. Our technicians use state-of-the-art tools, including borescope cameras and pressure differential testing, to map your duct system. We identify:
Leaks at joints and seams
Crushed or disconnected flex duct in attics
Corroded or torn metal ductwork
Poorly insulated sections causing energy loss
Blockages from debris or collapsed insulation
2. Advanced Air Duct Sealing Services in Denver
Sealing is our specialty. We don’t use temporary, DIY solutions. Depending on the duct type and location, we employ the most effective, durable methods:
Aeroseal® Technology: For leaks in inaccessible areas, we use this innovative polymer sealant. It is injected into the pressurized duct system, where it travels to leaks and seals them from the inside out with surgical precision. This is ideal for sealed walls or finished ceilings in homes across Cherry Creek or Highlands Ranch.
Mastic & Mesh Sealing: For accessible ductwork in basements or attics, we apply thick, paste-like mastic and fiberglass mesh tape over joints and seams. This creates a permanent, flexible seal far superior to duct tape, which fails quickly in Denver’s dry climate.
Metal Duct Repair & Reconnection: We repair torn sheet metal ducts with new sections and proper screws, then seal them with mastic. We also reattach completely disconnected runs that are wasting massive amounts of energy.
3. Complete Air Duct Repair & Replacement
Some damage requires more than sealant. Our repair services include:
Replacing Damaged Flex Duct: We remove crushed, torn, or mold-compromised flexible duct runs in your Thornton or Aurora attic and install new, properly sized and insulated R-8 flex duct.
Reinforcing Structural Integrity: We add additional straps and supports to prevent future sagging or disconnection.
Insulation Repair & Upgrade: We repair torn vapor barriers and replace missing insulation on ducts in unconditioned spaces, a critical step for energy efficiency in our climate.
