Breathe Easier and Save More: Why Air Duct Sealing in Salem, NH Is a Smart Investment
Inconsistent indoor temperatures? Dust buildup? High energy bills? These are common signs your HVAC system might be underperforming - often due to leaky ductwork. Air duct sealing in Salem, NH is one of the most effective solutions to improve indoor air quality, enhance HVAC efficiency, and reduce utility costs.
Whether you're a homeowner trying to lower your energy bills or a business owner seeking better indoor comfort, properly sealed ducts can make a dramatic difference.
What Is Air Duct Sealing and Why Does It Matter? Air duct sealing is the process of identifying and repairing leaks in the ductwork of your HVAC system to prevent air loss. In Salem, NH, where seasonal temperature extremes put HVAC systems to the test, sealing your air ducts can improve energy efficiency by up to 20%, enhance indoor comfort, and extend your HVAC system’s life.
The Importance of Air Duct Sealing in Salem, NH
In New England’s variable climate, your HVAC system works hard to keep your home or business comfortable. However, leaky air ducts can significantly undermine its performance. According to the U.S. Department of Energy, as much as 30% of conditioned air can be lost through gaps, holes, and poorly connected ducts.
By investing in air duct sealincorng in Salem, NH, you ensure that every dollar spent on heating or cooling your property is used efficiently—not wasted through leaks. For homes or businesses with unique layouts or aging duct systems, upgrading to a custom ductwork installation can further enhance airflow, comfort, and energy efficiency throughout your space.
Common Issues Caused by Leaky Ductwork
High Energy Bills: Your system works harder to compensate for lost air.
Uneven Heating or Cooling: Certain rooms feel too hot or too cold.
Poor Indoor Air Quality: Dust, allergens, and pollutants enter through leaks.
Strain on HVAC Equipment: Shortens system lifespan and increases maintenance needs.
How Air Duct Sealing Works
At Cornerstone Services, our duct sealing process includes:
Initial Inspection – Our technicians use advanced diagnostic tools to locate leaks.
Cleaning – Before sealing, ducts are cleaned to ensure effective adhesion of sealing material (link to internal Air Duct Cleaning page).
Sealing with Mastic or Aeroseal – We apply industry-grade materials to seal joints, gaps, and holes.
Final Testing – We recheck airflow and pressure to confirm that sealing was successful.
This professional approach ensures long-lasting results and improved HVAC performance.
Benefits of Air Duct Sealing in Salem, NH
