Approximately 25-40 percent of wasted energy in home heating and air systems results from leaking residential air ducts. Sealing of these leaks has always been very labor intensive and somewhat unreliable since access to the ducts and manually sealing them can sometimes be impossible.

DeHart is the first to offer innovative technology in the greater Modesto area with AEROSEAL. Aeroseal is a revolutionary sealing system that seals your air ducts from the inside, filling your air leaks with a patented gel solution that adheres to your ducts to seal all leaks up to 5/8".

The Aeroseal system begins with a diagnostic visit at your home with our testing specialist, to test your system for leakage. This is achieved with a computerized testing system that uses your house pressure to isolate leakage and airflow inefficiencies. The technician will process your information and present it to you in easy to read and understand information sheets. You will then be on your way to a healthier and more efficient air ducting system.

Upon completion you will receive a certificate of recognition that your system has been sealed, along with a ten-year guarantee of all sealing results.
