At Alpha Weatherization, we specialize in duct sealing services that enhance comfort, improve air quality, and lower energy costs for homes and businesses across Chicagoland. Your ductwork is the circulatory system of your building—responsible for delivering conditioned air from your HVAC system to every room. But when that system leaks, energy is wasted, comfort decreases, and your heating and cooling equipment must work harder than it should. Our expert duct sealing solutions address these issues at the source, ensuring that your system performs at peak efficiency year-round.
In many Chicagoland homes, as much as 20–30% of the air that moves through ducts is lost through leaks, holes, or poorly connected joints. That’s conditioned air you’ve already paid to heat or cool—escaping into attics, basements, or crawl spaces. Alpha Weatherization’s professional duct sealing service eliminates those losses through a meticulous process that improves airflow, reduces system strain, and creates a healthier, more efficient indoor environment.
How Duct Sealing Works
Our process begins with a comprehensive inspection of your duct system. Using advanced diagnostic tools, including pressure testing and thermal imaging, we identify the exact locations and severity of air leaks. These leaks are often found at connection points, around vents, or in hard-to-reach sections of ductwork. Once identified, we seal them with specialized mastic sealants, aerosolized sealing technologies, or durable metal-backed tapes designed specifically for HVAC applications.
Unlike temporary fixes or DIY patches, our professional-grade materials and methods are built to last. Every seal we apply improves the integrity of your duct system, ensuring that the air you pay to heat or cool reaches its intended destination—your living or working spaces.
Our Proven Process
We’ve refined our duct sealing approach to provide clear communication, consistent results, and measurable improvements in system performance.
1. Initial Consultation and Assessment
Our process starts with a detailed on-site evaluation. We inspect the accessible ductwork and perform tests to measure system efficiency and air leakage. This data-driven assessment allows us to create a plan tailored to your specific property and HVAC system.
2. Targeted Sealing Strategy
Based on our findings, we develop a customized sealing plan that addresses both the most significant leaks and the smaller gaps that collectively waste energy. We consider your system’s layout, accessibility, and airflow design to ensure maximum benefit from our work.
3. Professional Sealing and Testing
Our technicians then apply sealants to joints, seams, and connections throughout your duct system. For inaccessible or hidden sections, we use aerosol-based sealing technology that distributes sealant particles throughout the ducts, automatically closing leaks from the inside. Once sealing is complete, we retest the system to verify measurable reductions in leakage and improvements in overall airflow.
4. Final Verification and Clean-Up
We conclude every project with a thorough cleanup and a post-sealing performance report, so you can see the difference our work makes. The result is a more efficient, balanced HVAC system that delivers consistent comfort while reducing wear and tear on your equipment.
