Air Duct Sealing with Aeroseal Overview
Aug 15, 2024
Lecture Notes: Air Duct Sealing with Aeroseal
Introduction to Air Duct Issues
The EPA estimates that up to 40% of air moving through the duct system in homes is lost due to leaks.
Problems Caused by Air Duct Leaks:
Difficulty in heating and cooling certain rooms
Increased humidity levels
Entry of dust and allergens into living spaces
Higher heating and cooling bills
Challenges in Repairing Ducts:
Ducts are often located in concealed areas like walls, ceilings, attics, and basements
Traditional repairs can be difficult and expensive
Introduction to Aeroseal
Unique Solution:
Aeroseal is the only method that seals air ducts from inside the ductwork
No need for destructive access to walls or ceilings
Aeroseal Technology
How it Works:
Small, dry adhesive particles are blown into the blocked duct system.
Particles are heated and suspended in the air, moving through the duct system to find holes.
Particles attach to the edges of the holes to create seals.
Continues until the ductwork is entirely sealed.
Benefits:
Improved comfort
Better indoor air quality
Reduced energy bills
Home Seal Pro System
Technological Advancements:
Wireless capabilities and mobile Pro trailer system make installations easier and faster.
Aeroseal Process Steps
Initial Inspection:
Technician conducts a thorough inspection of the home.
All vents (supply and return) are blocked using closed cell foam blocks.
Setup:
Connection of flexible plastic tubing from Home Seal Pro unit @ trailer to injection point @ furnace.
The entire Aeroseal process is controlled by a wireless tablet.
Pre-Seal Test:
Conducted to measure the initial rate of leakage.
Sealing Process:
Wireless tablet allows for mobility for safety checks and consumer engagement.
Post-Seal Test:
A final leakage test is conducted.
Certificate of completion is provided, showing pre and post leakage rates and percentage of improvement (up to 98%).
Final Steps:
Removal of blocks from vents.
Injection point is patched.
Heating and cooling system is turned back on.
Conclusion
Effectiveness:
Aeroseal is an effective, affordable, and viable method for sealing air ducts.
Suitable for homes of all sizes and ages.
Considered the best solution available today for duct analysis and sealing.
