Air DUCT SEALING for Energy Efficiency

Seal Your Ducts from the Inside!

  • Improved Comfort
  • Improved Air Quality
  • Greater Energy Savings
  • Prolonged Heating/Cooling Equipment Life

In houses with forced-air heating and cooling systems, ducts are used to distribute conditioned air throughout the house. But in typical houses, about 25-40% of the air that moves through the duct system is lost due to leaks, holes, and poorly connected ducts. The result is higher utility bills and difficulty keeping the house comfortable, no matter how the thermostat is set.


STEP 1: Prep & Test

Prepare System / Blocking

Registers are temporarily blocked with foam plugs to force air in the duct work 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.

Connect System to Ductwork

Once the system is properly prepped, the Aeroseal machine is connected to the duct work 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.

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 25-40%).

STEP 2: Seal & Measure

Leaky Ducts Are Found

The patented aerosol sealant is injected as a mist into the ductwork. Holes and cracks in the duct system are found by the pressurization.

Sealant Seals The Ductwork

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

Monitor Process

This entire process is computer controlled so technicians can monitor the progress in real time and watch the minute by minute reduction in leakage.

STEP 3: Enjoy Comfort & Energy Savings

Certificate of Completion

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

The Results are Instant

Once the entire project is complete, homeowners will notice the results immediately. Temperatures throughout the home will be more even, 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.
