What is Aeroseal?

001Aeroseal Duct Sealing is an award winning patented breakthrough technology created by the department of energy, that tackles leaks from the inside out. This new technology offers homeowners an easy route to significant home energy savings, often up to a 30% reduction in energy use.

Heating and cooling costs represent the overwhelming majority of utility expenses for homeowners, and an average of 30% of that cost is leaking out the ductwork instead of being delivered to the rooms that need it. Aeroseal is the first effective solution to sealing leaky airducts located throughout the entire ductwork system.




The Problem:
You can see a water leak, but an air leak is invisible.

Duct leaks can be difficult and costly to find with duct work hidden between the walls, floors, and ceilings of any residential home or commercial building. The older, traditional use of mastic or taping of leaks not only is less effective than Aeroseal, but also can be very labor-intensive and expensive and can only be applied to ducts with physical access. Your home or building will typically experience some of these issues if you have leaky ducts:

002Thermal imbalance.

Hot or Cold Rooms are a Common Problem with a Simple Solution:
People struggling with high temperature variations between rooms or floors might not realize most of their conditioned air is escaping through duct leaks instead of flowing into their living space!
Your HVAC system is using energy to push conditioned air through your ductwork and into your living spaces. When your duct system contains leaks this conditioned air is actually pushed into your attic, crawlspace, or basement. Sealing your ductworks will allow your system to properly heat and cool your home by keeping conditioned air where you want it.



High Energy Bills:

Over 90% of existing buildings located throughout North America have air duct systems that contain small holes and cracks that reduce the level of comfort and increase heating and cooling costs. On average, 30 cents of every $1 spent on heating and cooling never makes it to your living spaces because it is leaking out of your ductwork! Only your thermostat can tell your furnace or air handler to stop running. If conditioned air can’t get to the thermostat your furnace or air conditioning unit will just keep on running.

003Your High Utility Bills may be caused by Duct Leaks:

Does your HVAC system run constantly? Do you notice higher than expected utility bills?
Duct leaks are caused by a variety of factors including the age of the dwelling, type of construction, type of ductwork and local building codes.
Repairing and patching leaks in HVAC duct systems saves cooling, heating, and fan energy. In air-based systems, ducts deliver all of the heating and cooling to conditioned spaces. Any duct leakage translates into extra air that must be supplied so sufficient heating or cooling reaches the conditioned space. This not only increases effective heating and cooling loads, it also increases fan energy due to increased flow and/or run time. Sealing duct leaks reduces the amount of heated or cooled air the supply fan must handle to deliver the same amount of air to the conditioned space.

004Dust and Allergies in Your Home:

Pollen, dust mites, mold, animal dander and other contaminates are common allergy triggers. There is not much you can do about pollen or dust outside of your home but when you’re indoors nothing is worse than having that month long runny nose during the fall or mold allergies in the spring.
When you have dirty and leaky ductwork in your home you can expect with 100% certainty that these common contaminates are in there with you.



Benefits of Duct Sealing with Aeroseal:

Aeroseal Home Duct Sealing can improve your home comfort, reduce your energy bills, and improve your indoor air quality:

• Thermal balancing & improved home comfort
The #1 reason home owners want Aeroseal Home Duct Sealing is because they experience hot and cold rooms or high temp differences between upstairs vs downstairs living areas. The majority of homes we see suffer from these issues due to leaky duct work not delivering conditioned air where it is meant to go! Our simple process seals leaky ductwork from the inside – even the hidden ductwork behind your walls!
• Receive before-and-after diagnostics of your HVAC system and let the proof speak for itself.
• Indoor air quality & home safety
• Energy Savings & Utility Bills
Nearly 50% of the average home’s and commercial building energy bill is spent on heating air conditioning and ventilation. Duct leakage in residential homes costs consumers $25 billion each year and costs much more to the commercial building operators / owners. On average, 30 cents of every $1 you spend on heating and cooling your home or building disappears into thin air due to duct leaks.
• Clean, safe and guaranteed for 10 years!


005Breaking down the process, how Aeroseal works

Step 1. Prepare Your System: Plugging your registers with foam forces the air in your duct work to escape through leaks. By forcing air to escape through leaks we are able to pretest your duct system and begin the duct sealing process.





006A small access hole is cut into the supply or return and a temporary collar is attached. The air conditioning indoor coil, fan, and furnace are temporarily blocked with a foam plug to prevent sealant particles from entering this part of your system.
The next step of the process is to pretest and inject non-toxic sealant into your duct work. The pretest measures exactly how much duct leakage your system has in square inches and also calculates just how much air is escaping through leaks in your duct work.




007 Step 2. Pretest Your Ductwork: Once the system is properly prepped the Aeroseal machine is connected to the duct work using lay flat tubing.
The Air Duct Diagnostic pretest will detect the exact amount of duct leakage in the duct system – the typical duct leakage detected in a home is between 30-40%.
Next, the non-toxic, UL tested and approved, aerosol sealant is injected into your duct system. As the sealant exits your ductwork through leaks it begins to collect on the edge of the hole until the leak is completely sealed. Aeroseal can seal leaks up to 5/8ths of an inch.



Step 3. Seal Your Ductwork: Small aerosol particles are injected and kept suspended in the airflow by continuous air movement. The aerosol particles begin collecting on the edges of holes and cracks in your duct work and seal your leaky duct work from the inside.
This entire process is computer controlled where you can monitor the results in real time showing you just how effective the Aeroseal process is. Ducts are sealed with only 1 to 2 oz. of sealant material.

Step 4. Review Your Results: A computer generated analysis summarizes your home’s duct leakage reduction providing you with verification of the success of the Aeroseal application.




010Step 5. Enjoy Improved Home Comfort & Indoor Air Quality!: Now that you’ve had your ductwork sealed with Aeroseal you can expect to experience increased home comfort, improved indoor air quality, and lower energy bills! Once the process is complete your certified Aeroseal technician will provide you with a printed certificate summarizing your results.
