About Us

MAVCAP Industries, the developer and manufacturer of A-C DrafShields, is a leading manufacturer of AC vent and grille covers, specifically those used for weatherization. Our range of products are being successfully applied across many industries, properly sealing off grilles, vents and associated duct work. Our products can be used for:

  • Winterizing a home or building

  • Energy audits

  • Duct cleaning

  • The containment of asbestos, smoke or debris

  • As a way to comply with the new EPA Renovation, Repair and Painting Lead Rule

  • Restoration

  • Construction

  • And more!

No matter what reasons you may have for blocking an air vent, MAVCAP's A-C DraftShields is the perfect instant and reusable HVAC seal for you! Along with offering a great product we also have:

  • Certification - Energy savings calculations have been thoroughly certified by the Chu & Gassman Engineering Company. They are New York professional engineering company and have been reviewed by Public Utility companies

  • Testing and Recognition – A-C DraftShields have also been tested by the American Energy Audit, a RESNET approved Training and Quality Assurance Provider. Their testing and recognition certification required our product to produce a positive pressure of 25 Pa (Pascal) and to hold a seal to 350 CFM, which it did

A-C DraftShields have also been adapted for use when you need to create a negative pressure and prevent debris from exiting the HVAC system. This can be useful during duct cleaning or to seal off duct work to prevent any contaminants, like debris, from entering the duct system during construction. A-C DraftShields has also been adapted to properly and fully seal off duct work and vents during duct pressurization and leak testing. No matter your need, all of our covers are reusable, certified and proven to work.
