Duct Leakage Testing

(how much air is leaking through the duct work)

Ducts running through attics or unheated crawlspaces are only allowed to leak 4 cubic feet per minute per 100 square feet of space that they serve. We like to test at the rough phase, because it is easier to isolate only the ductwork needing testing. You'll also be more likely to get passing results. As systems are built today, panned and stud cavity returns are very leaky by nature. The fewer of them needing to be tested, the better. Give us a call for help!
