Air Duct Sealing

Marshall Cleaning Service provides professional air duct sealing using Aeroseal technology to help reduce air leaks inside your duct system. Leaky ductwork can cause uneven temperatures, poor airflow, excess dust, higher energy bills, humidity problems, and reduced HVAC performance throughout your home.

Improve Comfort, Airflow, and Efficiency

Our air duct sealing service helps conditioned air reach the rooms where it belongs. By sealing leaks from inside the duct system, Aeroseal can help improve comfort, reduce wasted energy, support better overall HVAC performance, and help your home feel more consistent from room to room.

Cleaner Air

Help reduce dust, allergens, odors, and pollutants entering the duct system.

Why Leaky Ducts Are a Problem

Many homeowners assume furnace filters are enough to control the dust circulating through the home. However, leaky return ducts can pull dust, dirt, allergens, odors, humidity, and pollutants from attics, crawlspaces, wall cavities, and other unconditioned areas.

Once those contaminants enter the duct system, they can be pushed back into your living spaces over and over again. Added humidity inside the ductwork can also create comfort issues and may contribute to conditions where mold growth is more likely.

How Aeroseal Helps

Aeroseal seals duct leaks from the inside. Instead of tearing apart walls, ceilings, or duct runs, the sealing technology is introduced into the duct system and works to close small leaks where air is escaping.

This helps keep conditioned air moving where it should, while helping block unwanted dust, dirt, allergens, humidity, and odors from being pulled into your system.

Take Control of Dust with Aeroseal

Blocks Dust and Allergens

Sealed air returns help stop dust, dirt, allergens, and other pollutants from being pulled into your duct system and blown throughout your home.

Provides Healthier Airflow

By reducing duct leakage, your HVAC system can deliver more of the conditioned air you expect while helping keep unwanted contaminants out of the airflow.

Helps Control Humidity

Sealing return duct leaks can help prevent humid, unconditioned air from entering the system, which may help reduce moisture-related comfort problems.

Leaky Ducts Waste Energy

In many forced-air heating and cooling systems, a significant amount of conditioned air can be lost through leaks, holes, and poorly connected ducts. That means your HVAC system may run longer, work harder, and still struggle to keep the home comfortable.

Sealing duct leaks helps your system deliver more air to the rooms where it belongs. This can improve efficiency, lower energy waste, and help extend the life of your heating and cooling equipment.

Your Home Should Feel Comfortable in Every Room

Aeroseal can help reduce “dead zones,” improve airflow, balance temperatures, and make rooms feel more consistent. This is especially helpful for upstairs rooms, bedrooms, bonus rooms, and areas that never seem to heat or cool properly.

Pair Duct Sealing with Air Duct Cleaning

Professional duct sealing is a smart upgrade for many homes, especially when combined with air duct cleaning. Cleaning helps remove built-up dust and debris, while sealing helps reduce the leaks that can allow new dust, humidity, and pollutants to enter the system.
