Leaky ducts are one of the biggest issues we see in new home construction. Every connection along the duct system runs the risk of leakage if not properly installed and sealed.
The duct blaster used in conjunction with a smoke machine can identify the location of leaks in a HVAC system. This is especially helpful in new home construction as this test can be performed before the drywall is hung.
Builders wanting to obtain credit for energy efficient housing will need to test out at a certain level of tightness. Using these tools to ensure the ducts are tight while they are still accessible can prevent a lot of headache in the end. Once the drywall is hung there is little that can be done to identify and correct the leak.
