Aeroseal – duct sealing

What are the BENEFITS of DUCT SEALING for homeowners?

 

STEP 1: Prep and Test

1. Prepare System / Blocking

Preparing the Aeroseal duct sealing starts like this:

Registers are temporarily blocked with foam plugs to force air in the ductwork to escape through any leaks. Then, the air conditioning indoor coil, fan, and furnace are also temporarily blocked with a foam plug to prevent sealant particles from entering this part of the HVAC system.

2. Connect System to Ductwork

Once the system is properly prepped for duct seal, the Aeroseal machine is connected to the ductwork using lay-flat tubing. A small access hole (which will be closed upon project completion) is cut into the supply or return, and a temporary collar is attached. One end of the tubing connects to the collar; the other end connects to the Aeroseal machine.

      3. Pretest Ductwork

The Aeroseal system runs a pretest that pressurizes the duct system and provides a leakage reading on the computer. It will detect the exact amount of duct leakage in the duct system (the typical duct leakage detected in a home is between 30-40%). Many dealers will test the supply and return individually, while others will test them simultaneously.

STEP 2: Measure &  Duct Seal

1. Leaky duct seals Are Found

The patented aerosol sealant is injected as a mist into the ductwork. The pressurization finds holes and cracks in the duct system.

     2. Sealant Seals The Ductwork

The aerosol particles collect on the edges of holes and cracks in the ductwork to seal them from the inside.

3. Monitor Process

This entire Aeroseal duct sealing process is computer-controlled, so homeowners can monitor the progress in real time and watch the minute-by-minute reduction in leakage.

STEP 3: Enjoy Comfort & Energy Savings

1. Certificate of Completion

Upon completion, the homeowner is presented with verifiable proof of the seal in the form of a computer-generated certificate that includes the Aeroseal application’s before-and-after results.

2. The Results are Instant

Once the entire Aeroseal duct sealing project is complete, homeowners will notice the results immediately. Temperatures throughout the home will be evener, hot and cold spots should be eliminated, and the HVAC system will run more efficiently, which will help to save money on utility bills. Homeowners will also notice improved indoor air quality. There should be less dust, fewer allergens, and cleaner air.
