F A Q, or Frequently Asked Questions can be seen below.
Any additional questions can be asked through our Contact Us page.
Question 1. Will Aeroseal fix the comfort problems (hot or cold spots) in my home?
Answer 1. When we seal the ductwork, using the Aeroseal technology, you can expect the conditioned air to be delivered to where it is intended to go and not into the attic or to the outdoors. With proper duct design, it should greatly reduce the temperature differences between rooms & floors.
Question 2. Can Aeroseal reduce the amount of dust in my home?
Answer 2. Most ductwork runs through dirty attic spaces. Leaking ducts will pull in dust, insulation particles and other pollutants into the home. Aeroseal will reduce this leakage by up to 95% dramatically improving the indoor air quality.
Question 3. How much savings should I expect from Aeroseal?
Answer 3. Exact savings are hard to estimate due to many variables (house condition, duct design & leakage, efficiency of HVAC equipment, usage, etc.) but expect between 20% – 40% savings on your heating & cooling costs.
Question 4. How do I know if I need my ductwork sealed?
Answer 4. Schedule a duct or whole house assessment! We will visually inspect & pressure test the system to determine the amount of leakage and if Aeroseal would benefit your home.
Question 5.How long does it last?
Answer 5. Aeroseal has a 10 year guarantee but has been stressed tested in a laboratory to last more than 40 years.
Question 6. Is it safe?
Answer 6. The patented Aeroseal sealant is non-toxic and is used in hospitals, universities, surgery centers, clean rooms and government institutions. The main component is vinyl acetate polymer, which is used in water based paints and chewing gum.

Question 7. Is there an odor?
Answer 7. There may be a very mild odor, similar to Elmer’s Glue, during the sealing process that will dissipate within a few hours.
Question 8. Should I be in the home during the Aeroseal process?
Answer 8. While it is certainly safe to be in the home during the process, the HVAC system will be shut off during the process.
Question 9. Are there any VOC’s emitted by Aeroseal?
Answer 9. An independent lab found extremely low concentration of VOC’s during the sealing process. The primary component has no OSHA maximum exposure limits.
Question 10. How big of a leak will Aeroseal fix?
Answer 10. The Aeroseal process will seal just about any size hole with enough time & sealant, however any hole larger than 5/8” (about the size of a nickel) will be sealed manually. If hidden leaks are uncovered during the sealing event, the process will be stopped and a solution discussed.
Question 11. Where does the sealant leaking from the ductwork go?
Answer 11. Any sealant leaking from the duct system will settle in the attic or wall cavities. We filter the air in the home, during the sealing process, with an industrial air scrubber to capture any particles that may enter the living space.
Question 12. Will Aeroseal harm the HVAC system?
Answer 12. Our technicians are trained to isolate & protect all HVAC systems and components throughout the sealing process.
Question 13. Will Aeroseal harm electronics?
Answer 13. No, but we recommend any items with fans be turned off during the process.
Question 14. Does the ductwork need to be cleaned before the sealing?
Answer 14. Extremely dirty ducts should be cleaned prior to Aeroseal. Our technicians can assess the condition and make proper recommendations.
Question 15. Can the ductwork be cleaned after the Aeroseal process?
Answer 15. All types of ductwork can be successfully cleaned after they have been sealed with the Aeroseal technology.
Question 16. Will my ductwork be coated with sealant after Aeroseal?
Answer 16. Aeroseal does not line or coat the ductwork. The sealant only collects where the air is trying to escape (holes). Approximately 2 ounces of residual sealant remain in the duct system.
