Air Duct Sealing in Union City
Energy-Saving Through Duct Sealing in San Jose & the Bay Area
Once the leaking areas have been found, it is time to seal them off. Any cracks, gaps, or holes that have been identified must be closed to prevent air from escaping. There are three primary methods of duct sealing, each with its own pros and cons.
These methods include using:
- Duct sealing tape – This affordable technique is not very time-consuming and is easy to apply. However, it does not have the same amount of durability as other methods.
- Mastic duct sealant – Although it is quite messy to apply, mastic duct sealant is a great substance to fill gaps. Once it is hard, it can endure for quite a long time. Any drips should be wiped up before they are dry, to avoid having sealing where it doesn’t belong.
- Aeroseal ducting – For areas that are hard to reach, this sophisticated technology is known for being one of the best kinds of sealant. It pressurizes even the tiniest cracks using only the precise amount of sealant to avoid mess.

What Is Involved in Duct Leak Testing
Since there are so many negative effects of loose or leaky ducts, it is important to identify where these leaks are located. Then our professionals can get started on tightly sealing any places where the heated or cooled air is escaping.
During a leak test, our experts can set up specialized tools to measure the rate of airflow. As a calibrated fan blows out air, another appliance is used to sense the air pressure. Depending on the percentages of these factors, we can determine the levels of airtightness of the ducts.
