Aeroseal duct sealing by Duct Diagnostics in Connecticut

The Power of Aeroseal

When it comes to sealing ductwork, most homeowners and businesses don’t realize how much air — and money — is lost through leaks. Traditional methods like tape or mastic can cover visible damage, but they often miss leaks hidden behind walls or in hard-to-reach areas. That’s why our team relies on Aeroseal, an innovative and cost-effective solution that seals leaks from the inside out. It’s the smarter, more reliable way to make your ducts airtight.

How it Works

Developed at Lawrence Berkeley National Laboratory in 1994, Aeroseal uses advanced aerosolized technology to locate and seal duct leaks internally. A calibrated fan pressurizes the duct system, keeping sealant particles suspended until they reach areas of escaping air. As pressure changes, the particles are drawn to the leaks, where they collect and create a durable seal. This process works without coating the interior duct walls, targeting only the problem areas.

The results are immediate and powerful. Aeroseal improves system efficiency, reduces energy costs, and eliminates common issues like excess dust, humidity, and musty odors. By delivering air more effectively, it creates consistent comfort in every room. For most households, the savings on energy bills allow Aeroseal to pay for itself within three to five years — far more cost-effective than replacing windows or insulating walls.

The Benefits of Aeroseal Duct Sealing

Sealed ducts mean a more comfortable and healthier indoor environment. With Aeroseal, you’ll notice better temperature control throughout your home or business, ensuring cool rooms in the summer and warm spaces in the winter. Increased HVAC efficiency translates to lower energy bills and even the possibility of downsizing to a smaller, more affordable system. By reducing leaks, Aeroseal also improves indoor air quality, lowering exposure to dust, insulation particles, fumes, and allergens. In addition, it decreases carbon monoxide risks and reduces overall energy consumption, helping protect both your family and the environment.

Why Choose Aeroseal Duct Sealing?

Unlike traditional duct sealing methods that only address visible leaks, Aeroseal seals leaks throughout the entire duct system, even those hidden behind walls, ceilings, and floors.

Benefits of Aeroseal include:

  • Improved HVAC efficiency

  • Lower monthly energy costs

  • More consistent room temperatures

  • Better indoor air quality

  • Reduced dust and allergens

  • Improved airflow throughout the home

  • Reduced HVAC wear and tear

  • Increased overall comfort

  • Long-lasting results backed by extensive testing

Many homeowners combine Aeroseal with Residential Air Duct Cleaning for maximum HVAC efficiency and indoor air quality improvements.

Is Aeroseal Worth the Investment?

Many homes lose a significant percentage of conditioned air through duct leakage. By sealing these leaks, Aeroseal helps HVAC systems operate more efficiently and reduces wasted energy.

While every property is different, many homeowners recover the cost of Aeroseal through energy savings over time. In addition to lower utility bills, homeowners often experience improved comfort, better airflow, and reduced strain on HVAC equipment.

Along with Aeroseal duct sealing, professional Dryer Vent Cleaning services can help improve overall system performance and efficiency.
