Air Duct Sealing & Repair
Your HVAC system is responsible for keeping your home comfortable year-round, but damaged or leaking air ducts can severely impact its efficiency. Studies show that up to 30% of conditioned air can be lost due to leaks in ductwork. This means your heating and cooling system is working harder than necessary, leading to higher energy bills and uneven temperatures throughout your home or commercial space.
Leaky air ducts can also allow dust, allergens, and contaminants to enter your HVAC system and circulate throughout your living space. This can contribute to poor indoor air quality, causing allergies, respiratory issues, and overall discomfort.
By investing in professional air duct sealing and repair, you’re not only saving money on energy costs but also improving the air quality and comfort of your property. If your indoor space has inconsistent temperatures, high utility bills, or excessive dust, it’s time to consider a professional duct sealing service.

Helpful Tips for Maintaining Your Air Ducts
Change Your Air Filters Regularly
Dirty air filters restrict airflow and contribute to dust buildup in your ducts. Replace filters every 1-3 months to maintain clean and efficient airflow.
Keep Vents and Registers Clean
Regularly dust and vacuum your vents to prevent dirt and debris from entering your ductwork. This helps maintain good air quality and airflow.
Monitor Indoor Humidity Levels
Excess moisture can lead to mold growth inside your ducts. Use a dehumidifier if necessary to keep humidity levels between 30-50%.
Schedule Regular HVAC Maintenance
Professional inspections and cleanings help detect and fix small issues before they become major problems.

Frequently Asked Questions
Can air duct leaks cause higher energy bills?
Yes! Leaky ducts allow conditioned air to escape, making your HVAC system work harder to maintain the desired temperature. This leads to increased energy consumption and higher utility bills.
How is air duct sealing performed?
Professional air duct sealing involves identifying leaks, applying specialized sealants or mastic, and reinforcing weak connections. In some cases, aerosol-based sealing methods are used for maximum coverage.
Can I seal my air ducts myself?
While minor leaks might be temporarily sealed with tape, professional air duct sealing ensures a long-lasting solution. Experts use industry-grade materials and equipment to properly identify and fix leaks, improving your HVAC system’s overall efficiency.
