The #1 reason homeowners want Aeroseal Duct Sealing is because they experience hot and cold rooms or temperature 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! Simple, yet revolutionary process seals leaky ductwork from the inside – even the hidden ductwork that is behind your walls and otherwise unreachable!
Many homeowners notice dust collection around registers and higher than average dust collecting on surfaces throughout their homes. Leaky ducts pull dust, mold, and other pollutants into your home, presenting indoor air quality issues and creating and/or aggravating allergy problems. Duct leaks also contribute to safety issues in residential homes relating to back drafting of gas appliance fumes, auto exhaust and radon gas into your living space. Aeroseal home duct sealing will keep those dust, mold, and pollutants from being pulled into your living areas improving your air quality!
Nearly 50% of the average homes 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.
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. How Aeroseal Works: Preparing your System 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. How Aeroseal Works: Attaching the Collar 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.
Once the system is properly prepped the Aeroseal machine is connected to the duct work using lay flat tubing. How Aeroseal Works: 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.
Small aerosol particles are injected and kept suspended in the airflow by continuous air movement. How Aeroseal Works: Sealing your Ductwork 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.
A computer generated analysis summarizes your home’s duct leakage reduction providing you with verification of the success of the Aeroseal application. How Aeroseal Works: Before & After Sealing Once the process is complete your certified Aeroseal technician will provide you with a printed certificate summarizing your results.
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!
