How does Aeroseal Work?
Aeroseal is a patented breakthrough technology that tackles duct leaks from the inside out. The Aeroseal process puts escaping air under pressure and causes polymer particles to stick first to the edges of a leak, then to each other until the leak is completely sealed.
Breaking down the process & how Aeroseal works
From preparation to pretesting your ductwork all the way to handing you your Aeroseal certificate.
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.
A 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.
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.
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.
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.
Once the process is complete your certified Aeroseal technician will provide you with a printed certificate summarizing your results.
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!
Dust & Allergies
Dust 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 leaky ductwork in your home you can expect with 100% certainty that these common contaminates are in there with you.
Dust and allergies in your home may be caused by Duct Leaks
Do you notice substantial dust in your home?
Ductwork is typically run through attics, crawlspaces, basements or even behind walls. When you have leaks in your ductwork, they will suck air from these spaces into your living areas.
By sealing your ductwork you can limit the entrance points of your home that allow dust, pollen, or mold into your home and insure a much cleaner & healthier environment.
Homeowners who seal their ductwork with Aeroseal experience less dust and allergies in their homes!
Lower Your 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!
Your 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.
