The North American Insulation Manufacturers association put together a great handout explaining this in detail ⮕
Blower door testing is a way to test the "leakiness" of your home. By depressurizing your home and measuring the rate at which air infiltrates through imperfections in the building envelope.
As part of this process, we will inspect the house with a smoke stick to pinpoint potentially hidden air leaks (making it much easier to address them when the time comes to get to work). We also offer blower door testing as an isolated service to test the effectiveness of improvements that have been made to a home, and to provide homeowners and contractors with a roadmap to further improve a home's efficiency moving forward.
Green South Energy's duct leakage testing services can determine exactly how much energy your home or building is losing through leaky ducts, and how much money you could save by sealing those ducts.
A duct blaster is a sophisticated piece of diagnostic equipment which connects to your home's duct system and measures the rate at which ducts leak air. The duct blaster looks much like a blower door, and is essentially a high-powered fan that connects to a computer, where our diagnostic software measures rates of air infiltration. Using the results of the duct blaster test, we can help you determine whether your home or building would benefit from a duct sealing upgrade, and to what extent.

We offer infrared thermal imaging throughout the region, both as part of our comprehensive home energy audit and as a stand-alone service designed to pinpoint energy waste and other building science issues.
Having your home evaluated with an infrared scanner sheds valuable light on the effectiveness of your home's thermal envelope. An infrared scanner reveals hidden air leaks and areas where insulation isn't performing, and can also yield some interesting surprises -- such as where an uninsulated hot water pipe or recessed lights may be contributing to an ice dam, for an example. It's a valuable part of any good home energy audit, and a step that we guarantee to take with thoroughness and precision.
