When you flick on your central heating or cooling, you want to know that all that treated air is going into your living spaces. Minimizing wasted air means one thing: HVAC duct sealing.

Here’s how getting your ducts sealed (and choosing Aeroseal to do it) can help you get the most out of your furnace and air conditioner whenever they switch on.

First, What Is Duct Sealing?

Your ducts are made up of pieces, attached as tightly as possible to reduce air leaking into parts of your home that you don’t need to heat or cool. Your HVAC system needs to work harder to push air through leaky ducts.

When it comes to leaky ducts, your HVAC system needs help to run at peak efficiency. Professional duct sealing makes your ducts more airtight, leading to less wasted hot or cold air. Technicians insulate your ducts, then apply a sealant inside them to prevent air leaks.

That means that whenever your AC or heat pump turns on to combat a steamy Indianapolis summer, less cool air escapes to places like your crawl space or the attic. When winter hits Avon, Mooresville, or Plainfield, a sealed duct system means less heat loss between your furnace and distant areas of the house.

How Aeroseal Is Different from Other Duct Sealing Methods

Aeroseal is a type of duct sealant that disperses as a vapor, allowing it to comprehensively coat the interior of your vents more freely through your system than a liquid, foam, or putty-style sealant. As a technician applies Aeroseal, it gets into and fills the tiny cracks and crevices that are nearly impossible to find with the naked eye.

Leaky air ducts mean losing up to 25–40% of treated air, according to the U.S. Department of Energy. Aeroseal can help your Indianapolis home dramatically reduce that waste and cut the loss of cooled or heated air.

How to Seal Leaking Air Ducts with Help from the Professionals

When you schedule duct sealing, a professional HVAC technician handles everything from start to finish. Here’s what our technicians will do:

  1. Pressurize your duct system. The first thing your technician will do is seal each HVAC vent and register and pressurize your system. This allows us to get a “before” snapshot of how much air is leaking from your untreated ducts. As the pressure decreases, your technician will measure air leakage to create a baseline.

  2. Apply Aeroseal. Next, your technician will apply Aeroseal by distributing the sealant through the ductwork. We’ll measure how much sealant your system needs based on the size of your home and how extensive your ductwork is.

  3. Re-measure. When the Aeroseal has settled, your technician will take a new pressure measurement of the system to catch any remaining leaks and make sure the sealant has traveled throughout the entire length of the duct system.

  4. Cleanup. Your technician will clean up the minimal waste from the procedure and re-open your HVAC system for use.

Is Aeroseal Worth It?

Yes! Aeroseal’s water vapor-based formula not only allows it to easily and quickly fill cracks throughout your system, but it also has other benefits:

  • Reduced energy use. Because more heated and cooled air will be carried to your living spaces, your HVAC system won’t have to work as hard or as often to maintain your desired temperature. That means your energy bills will go down, too!

  • Lessened wear and tear. Duct sealing means that your system can do more heating and cooling with less work, reducing stress on your AC and furnace.

  • Minimal cleanup. Aeroseal’s formula means that almost all of it goes toward sealing, with very little waste. That means that your technician will have to spend almost no time cleaning up once the job is done, letting you enjoy your HVAC system sooner.

  • All-access formula. Because Aeroseal is vaporized, it travels throughout your entire system without needing to access each individual duct. This is ideal for hard-to-reach ducts, especially ducts behind walls.
