Aeroseal® Duct Sealing

Aeroseal® Duct Sealing

What is Aeroseal?

Aeroseal was developed in conjunction with the U.S. Department of Energy and is a revolutionary air duct sealer. This innovative technology reduces air leakage by sealing duct systems from the inside! The elastic polymer builds up in duct gaps but does NOT coat the inside of the sheet metal. As a result, after Aeroseal has been applied, ducts can still be cleaned without damaging sealed areas. The Aeroseal polymer will fill gaps up to ⅝ inches! The Aeroseal treatment is clean and virtually odorless. This system is applied by a trained Mendel Technical Representative and is backed by Mendel so you have complete peace of mind!

The Clean & Seal package from Mendel offers a complete air duct service to keep your home cleaner and healthier. We use the special Rotobrush system to thoroughly clean your air ducts; after cleaning, we seal air duct leaks with the revolutionary Aeroseal® elastic polymer that builds up in duct gaps but does NOT coat the inside of the sheet metal. You can choose from several packages offered by Mendel.

For duct sealing only, we offer the Whole-House Aeroseal Duct Service, which seals leaks up to ⅝" and will not crack or chip with the natural expansion and contraction of you sheet metal ductwork. Aeroseal is unique as it seals leaks in ductwork buried in your walls and floors as well as the leaks in ductwork you can see.

Energy Conservation - Lower Utility Bills

Air duct leakage not only impacts the comfort level in your home, but is a huge waste of America’s energy resources, amounting to $25 billion per year! In fact, a study by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) shows that 20% – 40% of air loss through leaky ducts goes into walls, ceilings and attic cavities, decreasing your home’s comfort level. This is especially concerning when we realize that, on average, 50% of our utility bill each month is spent on heating and air conditioning!

Why Choose Aeroseal from Mendel

  • Your Home is more Comfortable
    Air duct sealing and insulating helps solve common problems, such as rooms that are too hot in the summer or too cool in the winter.
  • Improved Air Quality—You Live in a Healthier Environment
    Fumes from household and garden chemicals, insulation particles and dust can enter your duct system, aggravating allergies and asthma. Duct sealing improves the air quality by reducing the risk of pollutants entering the ducts and circulating in your home.
  • Keep More Money in your Pocket
    Leaky ducts can significantly reduce heating and cooling system efficiency by as much as 20% or more. Sealing and insulating ducts increases efficiency thus lowering your energy bills. The investment made by many customers is paid back is just a few seasons! And if you plan to install new heating and cooling equipment, a sealed duct system may allow you to downsize to a smaller, less costly system that provides better dehumidification.
  • Eliminate Harmful Gasses—Clean Air Equals Good Health
    Leaky duct work in your heating and cooling system may cause back-drafts, in which gases are drawn back into the living space, rather than expelled to the outdoors. Sealing can minimize this risk.
  • Good Stewardship—Eliminate Harmful Air Pollution
    By sealing your ducts and reducing the amount of energy necessary to comfortably heat or cool your home, you can reduce the amount of air pollution generated.

The Mendel Experience

  • Efficiency Improvement Results in Cost Savings
    A recent study by McKinsey & Company shows the potential energy savings derived from various simple home improvements. Duct sealing saves such a significant amount of energy that the required investment would be paid for by the money you save on heating and cooling bills!
  • Leakage Reduction Provides Greater Heating & Cooling Capacity
    On a recent duct-sealing job, Mendel reduced the amount of duct leakage by 94% — from 841 Cubic Feet / Minute (CFM) to 51 CFM. See the Certificate of Completion for details — and imagine how much more comfortable your home could be!

Aeroseal Wins a Top Honor

On January 25th – 27th, thousands of HVAC industry experts, from around the world, met at the Orange County Convention Center in Orlando, FL for the 2016 AHR EXPO. This is the industry’s biggest gathering and a showcase of the latest and greatest innovations the industry has to offer. As part of this annual event, organizers review the latest products and technologies in ten different categories and award the Product of The Year Award.

This year, Aeroseal Technology was selected as the Product of The Year Award winner! Aeroseal has won many awards over the last few years, but this is a big one! Not only because it was selected by a panel of some of the HVAC industry’s leading members, but because it was given in recognition of Aeroseal’s game-changing effect on our industry. This award underscores the experiences we have in the field… Aeroseal is now solving the unsolvable. This dynamic new product is changing the way we look at indoor air quality, energy saving strategies, and other HVAC-related issues!
