Breathe Easier, Save Money, Live Better 

Here's what Aeroseal Duct Sealing services can mean for you


Save Money with Energy Efficiency

Leaky ducts can waste a significant amount of the heated or cooled air your HVAC system produces. By sealing your ducts, you're ensuring more of that conditioned air reaches the rooms it's intended for, enhancing your system's energy efficiency and potentially reducing your utility bills.


Lengthen Your HVAC Lifespan

A well-sealed duct system helps your HVAC equipment operate more efficiently, reducing the strain on your system and potentially extending its lifespan.


Breathe cleaner, fresher air

Leaks in your ductwork can draw in dust, allergens, and other pollutants from your attic or crawlspace and circulate them throughout your home. Aeroseal duct sealing helps to prevent this, contributing to a cleaner and healthier indoor environment.


Create Consistent Room Temperature

Do you have rooms that are too hot in the summer or too cold in the winter? Aeroseal can help. By ensuring conditioned air isn't lost to leaks, it can help maintain consistent temperatures throughout your home.

Our Aeroseal Duct Sealing Process

Here's what solutions we can provide:

Inspecting a Prefabricated Wall

Our technicians begin by inspecting your existing ductwork to identify the scope and nature of any leaks.

Protective Gear

All registers are then temporarily blocked with foam plugs to prevent the sealant from escaping.

Mopping the Floors
Inject Sealant

A small access hole is made in the supply or return and a temporary collar is installed. The patented Aeroseal duct sealing process begins by injecting a fog of aerosolized sealant particles into the duct system.

Sanitation Unit
Seal Leaks

As the sealant mist travels through your ductwork, the particles stick to the edges of leaks and begin to accumulate. This buildup eventually seals the leaks.

Final Inspection and Report

After the sealing process is complete, we conduct another inspection to ensure all leaks have been sealed. We provide you with a detailed report showing the before and after sealing leakage measurements.

We always leave your home as we found it. All access holes are sealed, and any leftover materials are cleaned up and removed.

Questions about Duct Sealing in Maryland?

  • How long does an energy audit take?
    On average it can take 2-3 hours to complete an audit, with a potential of it taking 4+ hours. Houses with gas, oil or propane heat tend to be on the longer side compared to a house that has electric heat.
  • What do you do in an energy audit?
    Our team will take a comprehensive look at your home and find areas where you are losing energy and spending excess money on utility bills. We use a variety of testing equipment such as an infrared camera to check on insulation and leaks, a blower door test to find how much the home is leaking and where, and gas safety equipment to check for high CO and any gas leaks.
  • What do I receive at the end of the energy audit?
    You will receive a game plan for your home to maximize efficiency and comfort in the form of an audit report. This report will contain the findings from the inspection, recommendations to improve any issues with notes, and yearly savings to calculate ROI for any investment made in the home. You will also be qualified for rebates through utility sponsored programs (BGE, PEPCO, DELMARVA).
  • Where in the house do you need to go into?
    Ideally our team will have access to the entire home, but the priority areas will include the attic, HVAC room, bathrooms, kitchen, and any trouble areas. All doors will need to be able to be opened and closed during the audit for certain testing that is performed.
  • Where can I learn more about the rebate programs?
    You can use the following links to find the utilities website about the rebate programs. BGE- ; PEPCO- ; DELMARVA -
  • Why do I receive rebates?
    The rebates and energy efficiency programs are funded through the EmPOWER MD Act, which can be found as a sub-charge on the back of your utility bill. You can learn more on the state website here -
  • I already had an energy audit, can I have another one done?
    An energy audit is good for one full year before the rebates associated with the inspection expire. If you have had an audit over a year ago and would like to consider rebates you will need to have a second audit to refresh the rebates. The refresher audit will cost $300 as the $100 is a one time only offer and the full cost is supplemented by the utility.
