AeroSeal is a service wherein our technicians would spray a special chemical in your ducts and vents. This special particle foam would seal leaks in your ducts and vents.


  • No hot and cold spots in the house
  • Up to 30% reduction in energy bills
  • Improves air-quality by not letting all insulation, bugs or other particles in the ducts
  • Gas appliances release combustion gases, so duct sealing prevents those gases to enter the house

Step 1: Preparation

  • All the vents in your house are sealed with foam so that the air in the ducts only escape through the leaks. Then a small escape is cut in the supply or return vent and the AC coil and the furnace are protected by foam so that the sealant cannot reach there.

Step 2: Pretest of the ductwork

  • Once the system is properly prepped the Aeroseal machine is connected to the ductwork using lay flat tubing. The Air Duct Diagnostic pretest will detect the exact amount of duct leakage in the duct system – the typical duct leakage detected in a home is between 30-40%.

Step 3: Seal the Ductwork

  • Small aerosol particles are injected and kept suspended in the airflow by continuous air movement. The aerosol particles begin collecting on the edges of holes and cracks in your ductwork and seal your leaky ductwork from the inside.  This entire process is computer controlled where you can monitor the results in real time showing you just how effective the Aeroseal process is. Ducts are sealed with only 1 to 2 oz. of the sealant material.

Step 4: Review the Results

  • A computer-generated analysis summarizes your home’s duct leakage reduction providing you with verification of the success of the Aeroseal application. Once the process is complete your certified Aeroseal technician will provide you with a printed certificate summarizing your results.
