Once we created an attic access in this homeowner's home, we found two bathroom attic fans that were exhausting into the attic. In the wintertime, this hot humid air, blowing into a cold attic will create condensation and possibly mold on organic material. We took action and vented them outside of the house through the gable.
This homeowner had moisture damage from sweating ductwork. In the 'Before' picture, you can even see the moisture pooling on the duct! The ducts were not insulated and the attic was poorly insulated. We applied our Tight 'N True encapsulation system to the sweating ducts to ensure that they stay dry and the house stays comfortable.
Attics can be 20 degrees in winter and 130 degrees in summer!
Your vented attic is the worst possible place to locate ducts. Attics are the extreme opposite temperature of the air your ducts are trying to move to your rooms. Ductwork also has lots of gaps and holes that can leak into the attic. The air you paid to heat and cool and want to go to your rooms leaks out of the ducts into the attic, lost forever, or is exposed to major opposing temperature differences in the attic.
Duct encapsulation and sealing gaps and joints in the ductwork can prevent air loss and help your system run more efficiently. It keeps your ductwork at a steady temperature, meaning the air moving through the ducts isn't affected and will change the preferred temperature of your home more quickly.
