Residential Air Duct Sealing VA

The #1 reason that homeowners want Aeroseal Home Duct Sealing is because they experience uncomfortable rooms that are too hot and too cold or large temperature differences between the upstairs and downstairs floors. We find that most of these homes that suffer from hot and cold spots are due to leaky duct work that is unable to deliver conditioned air where it is meant to go!

Increase Your Comfort

Our simple process seals leaky duct work from the inside- even the hidden duct work in your walls, floors, attic, and crawlspace!

Sealed duct systems allow heated and cooled air to be properly distributed to the intended areas, resulting in a more comfortable living environment!

Live Healthier

Many homeowners notice higher than average dust on their registers and throughout their home- even after having their HVAC system cleaned. Leaky duct work pulls dust, mold, humidity, and other allergens and contaminants into your home and presenting frustrating indoor air quality issues and / or allergy problems.

Duct leaks also contribute to safety issues with back drafting gas appliance fumes and drawing radon into your living spaces.

Our simple process provides an EPA endorsed solution and a patented verification that your system is as leak- free as possible!


Energy Savings

Nearly 50% of the average home’s energy bill is spent on heating, air conditioning, and ventilation. According to the US Department of Energy duct leakage costs homeowners $25 billion each year, and even much more than that to commercial building operators and owners.

On average, 30 cents of every $1 you spend on heating and cooling your home disappears because of duct leaks in your HVAC system.

Our simple process seals duct work quickly and efficently from the inside so your unit doesn’t run as long, your utility bills aren’t as high, and your thermostat is satisfied faster!

Air Duct Sealing- Frequently Asked Questions

A series of government reports have shown that air duct sealing can lead to as much as $850 in energy savings per year. Some homeowners have saved up to 40% on their energy bill. Naturally, exact savings are difficult to precisely estimate since they depend on a multitude of variables such as your weather, house condition and design, your heating and air conditioning system, system usage – as well as other factors like energy prices.

How our Aeroseal process works:

– Preseal test to measure the leakage as a baseline for measuring progress.

– Block off the registers with foam or plastic.

– Inject an UL tested and approved aerosol into the duct system.

– Since the air has no place to go except out through the leaks (the registers are blocked), the sealant material is deposited precisely at the air duct holes or cracks where leakage occurs.

– A computer and sensors are used to measure and control the progress. The technology is patented from the University of California and the process is endorsed by the Environmental Protection Agency.

– Postseal test to measure improvements.

– Complete report and certificate printed on the spot to provide a record of improvements.

Holes and cracks up to 5/8th of an inch wide can be completely sealed.

Inspection discovers any obvious break in the duct work and, as the initial step of the sealing process, the Aeroseal system will establish an exact amount of leakage in the duct system. Of course, many people already know that a room or two in their house doesn’t get good air circulation because they can feel it. Or, they already know that their energy bill is high because they see it. The diagnostic measurement, provides a scientifically valid means to understand the performance of your air duct system. Many people are surprised to learn that homes typically leak 30% to 40% or more of their air through air duct leaks.

Also, all of our Aeroseal air duct certified technicians are qualified to run a program made by the Environmental Protection Agency (EPA) called “Duct Investor”. Duct Investor takes a comprehensive list of variables and provides a homeowner with the best available estimate of what they should realize in cost savings.

The vinyl sealing material remains rubbery, never cracking.

The sealing material has been found in rigorous testing to last over 10 years without failure.

It’s likely that the holes and cracks in the ductwork have allowed dust and other particulate matter to enter the system. If you are experiencing extensive levels of household dust, this might be the reason. In most instances, duct cleaning is found to be required prior to Aeroseal sealing. Your Air Duct Solutions representative can advise whether it will be necessary to clean your ductwork prior to sealing.

The sealant only sticks to the holes in the air duct without coating the rest of the duct.

The sealant material consists of a water-based solution (65% water) prior to application. The dried sealant material primarily contains two chemicals, vinyl acetate polymer (VAP) and 2-ethyl-1 hexanol (2E1H). The vast majority of what is left in the duct system is VAP, which has been used in water-based paints, adhesives, and hair spray. VAP has been used in chewing gum, and has no OSHA Exposure Limit. 2E1H is a common industrial solvent and is not considered toxic by OSHA. A review of the literature showed no ill effects after long-term exposure to concentrations of 200 ppm. The largest concentration of 2E1H measured in test houses was 1 ppb (200,000 times smaller), during Aeroseal injection. The sealant is UL-listed for smoke generation and flame spread (UL 723 0,0), and additional testing by UL showed no signs of mold growth or erosion.

    "I can’t thank you enough for the change in our 2 rooms we could not heat or cool upstairs. Even though our home is only 10 years old, we have used space heaters in these 2 rooms during the winter and used additional fans in the summer. After you sealed the ducts, we have not used any of these additional units. Our temperature has been constant throughout the house. Also, as a bonus our energy bills dropped 8%."

    "When I reviewed my energy bill after the first three months following Aeroseal, I was disappointed that my bill went up. Then after I realized I had switched to variable rates, I reviewed my usage…it went down by 11%, with no other changes in my home. Besides the excellent comfort enhancements, I am excited to get that kind of additional energy savings."

    "I just wanted to drop you a quick note regarding the performance of our AC unit since you all did the duct sealing. Before the sealing when running the AC we had a temperature differential of approx 15 degress between the basement and the second floor, we had to run the AC so cold to get the upstairs halfway comfortable. We would also run a single room AC unit in the master bedroom to get it cool at night. With today's temp hitting 87 I checked the temperature was only 3 degrees difference between the basement and second floor. No more room AC unit for us, plus we get to raise the overall AC temp by several degrees since it's working so much better. Thank you for doing such great work. We are big fans of the process and have told all of our friends. Keep up the great work."
