Aeroseal Home HVAC Duct Sealing

How Aeroseal Duct Sealing Works?

The process begins with our technicians sealing off your home's vents and registers. Then, a small, temporary access hole is made in your ductwork to connect the Aeroseal machine. The system's computer measures the amount of leakage in your ducts before any sealing begins, providing a baseline measurement.

Next, the Aeroseal machine pressurizes the ductwork and injects the sealant mist. The sealant particles are carried by the air to every leak, where they stick to the edges of the holes and to each other, forming a tight, durable seal. 

The computer monitors the entire process, providing a real-time graph that shows the leakage rate decreasing as the seals are formed.

Once the duct sealing is complete, the machine provides a final measurement and a certified report showing the improvement. This report details the "before and after" leakage rates, proving the effectiveness of the duct sealing treatment.

How Do You Know if You Need Duct Sealing?

Aeroseal duct sealing is a powerful solution that addresses several key problems often faced by homeowners due to leaky ductwork. 
These issues, which can be difficult to diagnose without professional equipment, often lead to a less comfortable, less healthy, and more expensive living environment.

Here's a breakdown of the primary issues Aeroseal solves:

1. High Energy Bills

Leaky ducts can be a major source of energy waste. A home with leaky HVAC ducts can lose 20-30% of its conditioned air (heated or cooled) through cracks and gaps in the ductwork. These cracks and gaps force your HVAC system to keep running longer and working harder to reach and maintain the right temperature. By sealing these leaks, Aeroseal reduces the workload on your system, leading to significant savings on your monthly energy bills.

2. Uneven temperatures and lack of comfort 

If you have "hot spots" or "cold spots" in your home, it's a classic sign of leaky ducts. The conditioned air that is supposed to be delivered to every room is escaping into unconditioned areas like attics, crawl spaces, or wall cavities. Aeroseal ensures that the right amount of air reaches every vent, eliminating temperature imbalances and creating consistent comfort throughout your home.

3. Poor Indoor Air Quality

Your duct system is not just for distributing air—it's a closed loop. When there are holes in the return ducts, your system can pull in unfiltered air from attics, basements, or garages. This air often contains dust, allergens, insulation fibers, and other pollutants. Aeroseal seals these entry points, preventing the contamination of your indoor air and leading to a cleaner, healthier environment.

4. Excessive Dust Indoors

If you find yourself constantly dusting, leaky ducts could be the culprit. As mentioned above, holes in your ducts can draw in large amounts of dust and debris from unconditioned spaces and then circulate it throughout your home. Sealing the ducts dramatically reduces this influx of dust, making your home noticeably cleaner.

5. Overworked HVAC System

When your HVAC system has to constantly compensate for lost air, it's under increased strain. This accelerated wear and tear on your HVAC system can lead to frequent breakdowns and a shortened lifespan for your equipment.
