What factors affect the cost of duct sealing?

  • Size of your home: Larger homes with larger ductwork systems typically require more time to inspect and seal, which increases your overall costs. That said, we value your time and budget, which means we'll work hard to seal your ducts quickly.
  • Accessibility: Sometimes ductwork can be hard to reach, such as in a tight crawl space. If accessibility is an issue, your technician may need to spend more time sealing your ducts. However, you can rest assured that we'll work as efficiently as possible.
  • Severe damage: If your ductwork is severely damaged with large gaps and cracks, sealing may not be possible. In this case, we'll probably recommend replacing your ducts altogether, saving you money in the long run.

Customer Review

...courteous and professional... a pleasure to work with.

Jimmy and Mike came over inspected the ductwork, cleaned the drains, and changed the capacitors on the compressors on both of the external units. They also cleaned the condensers to maintain good airflow. They were courteous and professional and generally a pleasure to work with. It is so good to feel confident in dealing with a company that wants to provide good service.
