A Few Things
To Know

The ductwork that is separated at the joints, plenums with broken or rusted‐out seams, improperly sealed access openings or doors, and other sources of air leakage can be a significant source of energy waste.


We’ll get those ducts ready


Plugging your registers with foam forces the air in your ductwork to escape through leaks. By forcing air to escape through leaks we able to pretest your duct system and begin the duct sealing process.

Preparing your system for air duct sealing


Getting ready for the sealant


A small access hole is cut into the supply or return and a temporary collar is attached. The air conditioning indoor coil, fan, and furnace are temporarily blocked with a foam plug to prevent sealant particles from entering this part of your system.

Preparing your unit for air duct sealing


We are ready for the Aeroseal machine


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%.

Pretesting your ductwork before air duct sealing


Time to find the holes and cracks


Small aeroseal particles are injected and kept suspended in the airflow by continuous air movement. The aeroseal particles begin collecting on the edges of holes and cracks in your ductwork and seal your leaky ductwork from the inside.
