Duct Sealing

Aeroseal Duct Sealing

On average, air transportation systems (heating and air conditioning ducts) leak about 25-40%. All of this lost air is not only conditioning unusable space (behind walls, crawl spaces, etc.), but it is also picking up odors and dust from those spaces and transporting them throughout the house. As a result, the average savings generated from professional Aeroseal duct sealing could pay for itself in 3-5 years.

What are the Signs of Leaky Air Ducts?

Many homeowners and commercial businesses will notice early signs of leaky air ducts such as a change in room temperature, excessive humidity, an increase in dust, odors and fumes, and more costly energy bills. When you find yourself in this situation, it may be time to have your air ducts checked to see if they are leaking and are in need of professional air duct sealing.

Without professional care, leaky air ducts can lead to many issues that can negatively affect your health, your finances, and the indoor air quality of your home or business. Leaky air ducts will make it more difficult for your HVAC system to properly heat up or cool down your living or working space, which can lead to hot rooms in the summer and cold rooms in the winter. Leaking air ducts will also force your HVAC system to work harder, resulting in higher energy bills that will cost you money that otherwise could go towards other expenses. Excessive humidity levels are another result of poorly sealed air ducts that can lead to costly home repairs. Finally, having poorly sealed air ducts can lead to excessive dust and odors and an increased risk of poor air quality that can lead to future health issues for individuals suffering from respiratory illnesses, such as asthma.

How Do We Get This Done?

Duct Diagnostics’ Aeroseal sealing process only takes about a day per system to complete and is covered in 5 simple steps:

  1. Before heading to your home or business, our team makes sure that our truck has all the necessary equipment needed to get the job done. This equipment includes an air dryer, a fan box, 2 heaters within this fan box, 36” layflat tubing that attaches to the air ducts and laptop equipment used to monitor both our pretesting and post testing results.
  2. Once we arrive on site, we insert a foam block into the register and also block off the HVAC system, sectioning off the air ductwork that needs to be sealed.
  3. After all blocks have been placed, we perform a Duct Blast pre-test. This pressure test allows us to determine how much CFM leakage currently occurs from our customers’ air ducts.
  4. Once the pretest is complete, we inject the polymer sealant material through your air ducts, seeking out and sealing holes and cracks up to 5/8th of an inch wide. The sealant material attaches directly to these problem areas, effectively sealing them without coating the inside of the ductwork. While this injection process takes place, we monitor the sealant’s progress using a specialized computer program on our laptop.
  5. Once the Aeroseal sealing process is complete and the polymer dries, which usually takes up to an hour, we perform a Duct Blast post-test. We then print out the sealing and tightness certificates, which verify that your air ducts have been successfully sealed.

Once we’ve completed the process, your seal is guaranteed for 10 years, 40 years testing.

What Are the Benefits of Aeroseal Duct Sealing?

Professional Aeroseal duct sealing services lead to increased comfort level of your home or business. You will have much greater control over room temperatures to keep your space cool during the summer and warm during the winter. Properly sealed ducts will also increase the efficiency of your heating and cooling system, lower your energy bills and allow you to downscale to a smaller and less costly heating and cooling system. Using Aeroseal to seal your air ducts will also reduce the risks of combustion gases like carbon monoxide entering your living or working space and will further improve your indoor air quality by reducing exposure to fumes from household and garden chemicals, insulation particles, and dust that can aggravate asthma and allergy problems. The Aeroseal process seals leaks nearly impossible to reach using traditional methods and contributes to an overall reduction of the amount of air pollution created from generating less energy.
