What Is Aeroseal?

Aeroseal is a state-of-the-art duct sealing method that seals ducts from the inside out. Developed by indoor air quality scientists at the Lawrence Berkeley National Laboratory, Aeroseal is recognized as the most effective way to seal and clean ducts for improved performance, and can reduce duct leakage by up to 90%!

National Heating and Air Conditioning is one of the few HVAC contractors in the Cincinnati region to offer Aeroseal. Since most ductwork is not accessible without a major disruption to the living space (ductwork in walls, in particular), sealing ducts from the inside using Aeroseal is a major technological breakthrough and an energy efficient, simple solution to the problem of leaky ducts. Read more about Aeroseal on their website.

How Does Aeroseal Duct Sealing Work?

Our duct sealing process begins with a thorough evaluation of your home’s duct system. We target any obvious external leaks using traditional duct sealing methods before applying the Aeroseal system.

Signs You Need Duct Sealing in Cincinnati

If your home isn’t cozy and comfortable as it should be, you could be facing a ductwork problem! At National Heating and Air Conditioning, we’ll help you spot the signs early, so you can recover from HVAC issues quickly. Here are the most common reasons homeowners turn to duct sealing services:

  • Odd smells from your HVAC vents: Improper duct sealing may lead to musty or moldy odors from your vents, which could be a result of an opening arising somewhere within your ductwork that is allowing new air in, as well as dust and debris!
  • Uneven heating and cooling in your home: If you’ve noticed hot spots or cold spots in your home, it may be due to duct blockages or leaks within your HVAC system. In this case, duct sealing is a process of locating and repairing the areas in your home that are receiving uneven hot or cold air.
  • Your energy bill keeps going up: If you’ve run up a tab on your energy bill lately, but haven’t seen improvements in the comfort of your home, your HVAC may not be running as efficiently as it should be. Ask our HVAC technicians to assess your home’s ductwork for any damages or repair needs. A few ductwork repairs could mean a lot of savings on heating and cooling!
