WHAT IS AEROSEAL?
Aeroseal Duct Sealing is a breakthrough that effectively seals up leaks from the inside out. Our trained technicians are skilled in the subtle art of the Aeroseal process and can walk you through the steps. Developed by the Indoor Environment Program at Lawrence Berkeley National Laboratory, the Aeroseal software was tested by some of the best Indoor Air Quality scientists in the country. Aeroseal Duct Sealing can reduce duct leakage by up to 90% and save a typical homeowner up to $1000 a year in energy costs and a typical building up to 30% of HVAC energy use.
Q: What size of holes can be sealed using the Aeroseal air duct sealing process?
A: Holes and cracks up to 5/8th of an inch wide can be completely sealed with Aeroseal.
Q: What does the Air Duct Diagnostic and Inspection tell me?
A: The inspections will pinpoint any duct work breaks within the duct system. Then our technicians and their technology will establish an exact amount of leakage in the system.
Q: What are the estimated savings?
A: According to a series of government reports, duct sealing can lead to as much as $850 in energy savings per year. Exact savings are difficult to estimate since every home or building is different. Savings depend on your home’s condition, weather, HVAC system, and more. Bruno Air Conditioning technicians can also run a program made by the EPA called “Duct Investor” that can provide the best available estimate of what you should realize in cost savings.
Q: How does an Aeroseal air duct seal work?
A: In a nutshell the process goes as follows:
- Pre-seal diagnostic to measure the leakage as a baseline for measuring progress
- Block off the registers with foam
- Inject a UL tested and approved aerosol into the duct system
- 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 process
- Post-seal test to measure improvements
- Complete report and certificate printed immediately to provide a record of improvements
Q: How long will the air duct sealing material last?
A: The sealing material has been tested to successfully last for over 10 years.
Q: Do air ducts need to be cleaned before air duct sealing?
A: In most cases, duct cleaning is not found to be required prior to Aeroseal sealing, however, a Bruno Air technician will advise you if it will be necessary to clean your ductwork prior to sealing.
Q: Does the sealant coat the inside of the ductwork?
A: The sealant will only stick to the holes and cracks within the air duct without coating the rest of the duct.
Q: Is the sealing material used by the Aeroseal air duct sealing system safe?
A: 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.
Q: Does the sealant leave an odor?
A: No, Aeroseal air duct sealing leaves no lingering odor.
Q: If the rooms of my home have inconsistent temperatures, can Aeroseal improve the performance of my heating and A/C system(s)?
A: The Aeroseal sealing system can help improve the comfort and temperature uniformity in your home by sealing the cracks and holes within your system. This will allow cool air to reach your entire home instead of just a few rooms.
Q: Can the Aeroseal air duct sealing system reduce the amount of dust in my home?
A: Yes, the Aeroseal air duct sealing system can reduce the amount of leakage by as much as 90%, reducing dust and other indoor air pollutants from the conditioned air in your home.
Q: Is the sealing guaranteed or can I get my money back? What if it doesn’t work?
A: Aeroseal provides a 10-year warranty on the seals created with our process. *Note: the warranty is for on-site seal failures and does not cover additional damage, wear or tear, and subsequent replacement of failed ducting.
Aeroseal Duct Sealing is proven to be the most effective means of securing and solving air leaks. It is available to be used in residential homes as well as commercial buildings. The process is done within 4 to 8 hours for entire home sealing. There’s an immediate difference in your home’s energy consumption and temperature. If you think your home has air leaks, contact us today to schedule a diagnostic.
Bruno Air Conditioning seals air leaks by using the UL approved sealing materials for efficiency and success. The duct sealing system also has a 10 year guarantee for residential applications.
Through our Aeroseal air duct diagnostic, one of our certified technicians will inspect and evaluate your HVAC unit to recommend ways to maximize efficiency and improve your home’s comfort. Using our tools, we can accurately gather reports on the building’s duct leakage and airflows. Inspections will largely focus on:
- Home/Building Construction
- Duct Work style
- Age of the establishment
- Disparity in room temperatures
- Indoor Air Quality issues
- High Energy bills and more
After all the information is gathered by a Bruno Air Conditioning professional, all room, ceiling, or floor registers are replaced with foam plugs. Once the area and system is sealed, the injection machine is connected to your air duct system through a tube and the process begins. The Aeroseal Duct Sealing injects the particles that then travel through the air duct system and attach themselves to holes or cracks, eliminating the leaks. Once complete, a Bruno Air Conditioning technician will verify that they have been appropriately sealed.
You will receive a sealing certificate and a tightness certification that will show duct leakage amounts before and after sealing, a graph of the sealing process, plus overall heating or cooling capacity improvement. The tightness certification will show the tightness of the duct system after completion of the sealing process.
Aeroseal Duct Sealing technology seals duct leaks in air distribution ducts by injecting a fog of aerosolized sealant particles into a pressurized duct system. What makes this so effective is that particles are suspended until they reach the edges of leaks. The particles then stick together to efficiently seal cracks and holes from within your system.
Aerosol particles are directed toward and deposit at the ductwork leaks because:
- All supply, return and exhaust grilles are temporarily sealed, so that all the airflow passes through the ductwork leaks;
- Small aerosol particles are kept suspended in the airflow by continuous air movement;
- As the air stream makes a sharp turn to exit through a leak, the particles collide with and adhere to the leak edges; and
- Using adhesive solid particles allows the built-up seal to span leaks as much as 5/8 inch wide.
Aeroseal Duct Sealing is a solution to high energy bills, air flow imbalances, and provides uniformity in comfort in every room. It also reduces the following from entering your home:
- Excess Humidity
- Automotive Exhaust
- Radon Gas
Did you know that American homes use almost 25% of the energy consumed in the United States, with the average household spending $2000 a year on home energy bills? Duct leakage costs home owners and professionals, billions each year simply for escaped energy. The leaks force your Heating, Ventilation, and Air Conditioner to work harder and cause performance concerns.
Air duct leaks also pose health concerns. A leak contributes to poor indoor air quality by allowing dust and other harmful particles inside your home. According to the EPA, most people spend roughly 90% of their lives indoors. This makes indoor air pollution one of the five most urgent environmental problems facing the United States.
Aeroseal Duct Sealing is a simple six step process conducted by Bruno Air Conditioning professionals that is affordable and successful. Improve your home’s comfort and restore your quality of life by sealing your air duct leaks from the inside with trusted, affordable, and effective technology.
- Wall registers are covered in order for air to escape only through the leaks
- Sealant is injected into the ducts for approximately 1 hour
- Small aerosol particles are kept suspended in the airflow by continuous air movement
- As the air stream makes a sharp turn to exit through a leak, the particles collide with and adhere to the leak edges
- Ducts are sealed with only 1-2 oz. of the sealant material remaining in the ducts
- A computer-generated analysis summarizing your home’s or building’s amount of leakage is generated, providing verification of success of the process
