Energy Audit professionals use AC-Draftshield to cover air duct grilles during pressure testing. Our energy audit series AC-Draftshield domes with a sensor port pre-installed for your convenience. Use additional vent covers without sensor ports to cover other AC vents, and save precious time during a routine energy audit.
Also consider the lack of garbage created by using a reusable vent cover as opposed to covering a vent with duct tape and disposable materials. Adding this up over the course of multiple inspections will not only save time and money, but also reduce your impact on the environment.
