The Perfect Time for Air Duct Insulation

If you’ve noticed rising energy costs, inconsistent room temperatures, or if your ductwork is located in unconditioned spaces, it’s time to consider air duct insulation. Aging systems and visible condensation are clear signs too. Modernizing your home with the help of proper air duct sealing or insulation services can extend the lifespan of your system by several years helping you save money and postpone full air duct replacement.

Help Your Aging System

Another service that may be required for aging systems is Air Duct Encapsulation, which works inside your ducts to ensure that no harmful fibers can enter the airflow.

Air duct encapsulation uses a protective coating inside ducts to stop harmful particles from entering the air. This coating, often applied to fiberglass duct liners in HVAC systems, prevents fiberglass fibers from mixing into air circulation, maintains duct structure, and helps improve HVAC efficiency and durability.

Insulation Options to Suit Your Needs

Choose from fiberglass or reflective insulation for air ducts, ensuring a custom fit that boosts both efficiency and comfort.

Rely on our professionals for a meticulous assessment, selection, and installation of the ideal insulation material. Ensure your ductwork meets the optimal R-value for air duct insulation to promote energy conservation.

Seal leaky air ducts for your system’s optimal performance.

Sealing leaky air ducts involves applying specialized materials such as mastic or metal tape to close gaps and cracks in the ducts. This method can be effective for small, accessible leaks but may not be sufficient for larger or more complex issues.

Air duct leak detection is an essential step in the sealing process. This involves identifying and locating the leaks in the ductwork.

To fully address leaky air ducts, a comprehensive approach is necessary. This may involve a combination of partial insulation, and other methods such as:

  • Aerosealing: This method involves using a pressurized system to seal leaks from the inside of the ducts. It is particularly effective for sealing hard-to-reach or hard-to-find fissures in the ductwork.
  • Duct cleaning: Cleaning the ducts can help remove debris and contaminants that may be contributing to leaks or compromising the overall performance of the HVAC system.
  • Duct replacement: In extreme cases, it may be necessary to replace damaged or deteriorated ducts to ensure the system operates efficiently and safely.
  • Regular maintenance: Regular inspections and maintenance of the HVAC system, including the ductwork, are essential for identifying and addressing potential issues before they become major problems

Benefits of Air Duct Sealing

By sealing air leaks, you can prevent the infiltration of unconditioned air, which can lead to reduced indoor air quality and increased energy bills.

You can also improve air pressure with air duct sealing. By ensuring a tight seal, you can maintain optimal air pressure and reduce the strain on your HVAC system.

Mastic vs. Metal Tape for Air Ducts

Mastic is a popular choice for sealing larger gaps and cracks, while metal tape is better suited for smaller, more precise applications.

The Best Sealant for Air Ducts

When it comes to choosing the best sealant for air ducts, Aeroseal is a popular and effective option. It is a laboratory-tested, long-lasting, and safe solution that can be applied from the inside of the ducts.

Preserve Your Comfort and Wallet

The cost of air duct sealing and full air duct insulation can vary depending on the size of the home and the scope of the work but it’s much less expensive than replacing the whole ductwork.

Our certified technicians are ready to transform your home’s energy usage, air quality, and overall comfort through air duct insulation and air duct sealing services. Protect your home and enjoy the benefits of well-insulated ducts.

Help The Environment

Properly sealed ducts help the environment by reducing the energy required for heating and cooling, thereby cutting down on greenhouse gas emissions associated with energy production. Additionally, it minimizes thermal loss, resulting in lower energy consumption and a subsequent reduction in the environmental impact of energy use.

Air Duct Sealing/ Insulation Frequently Asked Questions

  1. Is air duct insulation always necessary, or can proper maintenance eliminate the need for it?


Not necessarily, provided the initial installation was correctly performed and your HVAC system is regularly maintained.


  • If the installation is done according to all the rules, and the initial inspection for energy efficiency and safety is performed, then everything should be fine.
  • Regular filter changes and annual checks of the cooling coils are essential.
  • You also need to thoroughly clean the system once every 3 years, we are at your service for your Air Duct Cleaning needs.
  • Undetected minor system issues can, over time, lead to costly repairs (for example, if a filter does not fit tightly or is not regularly replaced, it can cause mold growth and damage to equipment)

Other factors that determine whether you’ll need this service:

  • Environmental factors: levels of humidity, temperature extremes, and how frequently the system is used
  1. What kind of materials are usually used for Air Duct Insulation? Why are those good materials? 

Fiberglass is commonly used for its excellent insulation properties. However, due to health risks associated with incorrect installation, such as the potential inhalation of tiny fiberglass particles, there are stringent installation guidelines. These particles can lodge in the lungs and increase cancer risks. Over time, fiberglass can also deteriorate into small particles, especially in environments where sound absorption is a factor.

In that case air duct encapsulation is the solution. The process involves sealing the surface of the duct board to prevent the release of harmful fibers into the air. This protective barrier ensures that the air circulating through your home remains clean and healthy.

  1. What kind of materials are used by MainDuct?

We use materials approved by the EPA (environment protection agency) for use in ventilation systems. These materials act as a protective barrier that separates the insulation materials from the air flow.

4. What is the difference between Air Duct Sealing and Air Duct Insulation?

Both are aimed at making sure your duct system is well-insulated. Air duct sealing focuses on specifically closing gaps, cracks, and leaks in the ductwork. Whereas Air duct insulation involves wrapping the whole ductwork with insulating materials.
